In the solar industry, the spotlight is often on panel performance and installation techniques. However, the transportation of solar mounting structures is a critical step that directly affects project timelines, product quality, and even site safety. Improper handling or logistical oversights can lead to damaged components, installation delays, or unnecessary costs.

Whether you're shipping across provinces or exporting internationally, here’s what you need to know to ensure safe, efficient delivery of solar racking systems.

 

 

 

1. Packaging Protection Matters

Solar mounting structures are typically made of aluminum (like 6005-T5) or hot-dip galvanized steel — both of which require careful handling during shipping to avoid:

Surface scratches or oxidation

Bending or warping of rails and clamps

Missing bolts or hardware

Recommended packaging methods:

Shrink-wrapped or foam-wrapped metal components

Wooden pallets or steel frames for long items like rails or posts

Boxed small parts with clear labeling

Anti-corrosion packaging for sea freight

 

2. Load Optimization and Labeling

Efficient loading reduces shipping costs and risks. Group items based on installation zones (e.g., roof vs. ground mounting kits) and label all components clearly.

Pro Tips:

Stackable bundles for aluminum rails with corner protection

Separate heavy steel parts from lightweight accessories

Include a detailed packing list with quantities and weights

 

 

 

3. Customs & Export Documentation

For international shipping, clear customs documentation is vital. Delays at ports can damage components due to exposure or poor handling.

Documents to prepare:

Commercial invoice

Packing list

Certificate of origin

Material data sheets (for aluminum, steel)

HS codes and descriptions (e.g., “solar PV mounting bracket system”)

 

4. Route and Environment Considerations

Climate and road conditions affect delivery quality:

In humid regions, use moisture-resistant packaging to avoid corrosion.

For long-haul inland transport, secure loads against vibrations or shifting.

In coastal shipments, extra rust protection (like oil coating or vapor-phase inhibitor paper) is advised for ZAM or carbon steel solar structures.

 

 

 

5. Handling at the Job Site

Once delivered, storage and on-site handling also matter:

Store components on flat ground away from water or mud

Avoid stacking beyond recommended height

Keep small parts kits in weather-proof containers

Use forklifts with padded arms for long rails to avoid bending

 

Conclusion

The journey of a solar mounting structure doesn’t begin at installation — it begins in the factory, and safe, strategic transportation is key to project success. From packaging to paperwork and onsite handling, each step must be planned carefully.

At TopFence, we understand the challenges of global logistics. That’s why our solar mounting systems are professionally packaged and labeled to ensure they arrive intact, on time, and installation-ready.

As solar technology evolves, mounting systems are becoming more versatile and cost-effective. One growing trend in solar PV installation is the rail-less (or "no-rail") mounting system, also known as direct-to-deck mounting. But when is this solution the best fit for your project? In this article, we’ll explore when and why a rail-less system might be the optimal choice.

 

 

 

What Is a Rail-less Solar Mounting System?

Unlike traditional systems that use long aluminum rails to support solar panels, a rail-less system eliminates the need for these rails. Instead, solar panel clamps and pv mounting brackets attach directly to the roof surface or structural members. This significantly reduces material use and simplifies logistics.

 

 

When to Use Rail-less Mounting Systems？

Small to Medium Residential Rooftops

For projects where panel count is limited and layout is straightforward, rail-less systems offer faster, more efficient installation without compromising on structural integrity.

Projects with Cost-Sensitive Budgets

Removing rails reduces material costs, packaging size, and shipping fees. For installers aiming to control overall system costs, this can make a real difference.

Low-Pitch or Flat Metal Roofs

Standing seam metal roofs are especially suitable. Mounting clamps can be directly attached without drilling, preserving roof integrity and simplifying installation.

Warehousing & Commercial Projects with Tight Timelines

Rail-less systems require fewer parts and tools, speeding up installation and reducing labor time—ideal for time-critical jobs.

 

 

 

When to Be Cautious

Complex Layouts or Large-Scale Ground Mounts: Rail-based systems provide better structural alignment across uneven terrain or non-uniform layouts.

Heavily Snow-Loaded Areas: Rails add strength and distribute weight more evenly; in high-load zones, rail-less may not meet structural requirements.

Tile Roofs: These require specialized hooks and mounting hardware—rail-less options are limited and may not be ideal.

Key Benefits of Rail-less Systems

Lower material cost and shipping fees

Faster installation and fewer tools required

Reduced rooftop load

Cleaner aesthetic (flush mount)

 

 

Conclusion

A rail-less solar mounting system can be a smart, efficient choice for residential and certain commercial rooftop applications—especially when simplicity, speed, and cost-effectiveness are priorities. However, each site has unique structural and climatic factors. Be sure to evaluate project conditions and local code compliance before choosing a no-rail solution.

As the solar energy industry continues to expand, so does the demand for durable, cost-effective, and long-lasting mounting materials. One standout solution gaining traction is ZAM-coated steel—an innovative material that is rapidly replacing traditional galvanized steel in many applications.

But what exactly is ZAM? And why are more solar companies and EPCs switching to it?

 

 

 

What Is ZAM?

ZAM stands for Zinc-Aluminum-Magnesium coated steel. It is a type of hot-dip alloy coating that consists of:

Zinc (Zn) – the primary corrosion-resistant element

Aluminum (Al) – enhances surface stability and oxidation resistance

Magnesium (Mg) – improves adhesion and provides self-healing properties

This combination creates a protective layer that performs far better than traditional hot-dip galvanizing (HDG) in many environments.

 

Top Reasons Customers Are Choosing ZAM

1. Superior Corrosion Resistance

ZAM offers 2 to 3 times better corrosion resistance compared to conventional HDG coatings, especially in:

Salt-spray environments (coastal, marine regions)

Industrial zones with high pollution

High-humidity climates

This longer service life translates directly into lower maintenance costs and longer-lasting installations.

 

 

2. Thinner Coating, Stronger Protection

Unlike HDG, which requires a thick zinc layer, ZAM can achieve better performance with thinner coatings (often 10–30μm). This results in:

Lighter structures

Better precision in component design and tolerance

Lower material usage, which is both cost-efficient and eco-friendly

3. Self-Healing Ability

Thanks to magnesium’s role in the alloy, ZAM-coated steel can self-heal scratches and cut edges, preventing rust from spreading—an advantage especially important during installation and transportation.

 

 

4. Excellent Weldability and Formability

ZAM-coated steel allows for easy:

Bending, punching, and rolling

Welding without extensive damage to the coating

This makes it ideal for complex solar racking designs and custom solutions.

5. Attractive Appearance

ZAM has a smooth, silvery finish, offering a clean, high-tech look that fits well in visible installations such as carports, fences, or rooftop solar systems in urban areas.

 

ZAM vs. HDG: A Quick Comparison

Feature	ZAM	HDG
Corrosion Resistance	★★★★☆	★★☆☆☆
Coating Thickness	Thin (10–30μm)	Thick (65–85μm)
Self-Healing	Yes	No
Appearance	Smooth & Clean	Rough & Matt
Cost	Slightly Higher	Lower Initial Cost
Environmental Impact	Lower Zinc Use	Higher Zinc Use

 

 

 

Conclusion

More and more solar developers are moving toward ZAM-coated steel because it offers long-term reliability, reduced total cost of ownership, and better performance in harsh environments. For projects requiring durability, efficiency, and a modern finish, ZAM is becoming the material of choice.

At Xiamen Topfence, we offer ZAM-based pv mounting systems tailored for both ground and rooftop PV projects. If you're planning a project that needs advanced protection with lasting value—ZAM is worth the upgrade.

In the solar mounting industry, carbon steel is widely used for its strength, durability, and cost-effectiveness. However, one common question arises: Will carbon steel rust? And if so, how can we prevent it? Let’s explore.

 

Does Carbon Steel Rust?

Yes, carbon steel is prone to rusting when exposed to moisture, oxygen, and other environmental elements. Unlike stainless steel or aluminum, carbon steel lacks sufficient corrosion resistance on its own. Over time, unprotected carbon steel will develop surface rust, which can compromise both the structural integrity and appearance of the solar mounting system.

 

 

Why Still Use Carbon Steel for Solar Structures?

Despite its susceptibility to rust, carbon steel remains popular in solar racking systems for several reasons:

High strength-to-weight ratio

Lower material cost compared to aluminum and stainless steel

Good load-bearing capacity for ground mount and large-scale projects

Easy fabrication and installation

To maximize its advantages, it’s crucial to apply effective anti-corrosion treatment.

 

Protection Methods for Carbon Steel Structures

Here are the most common and effective surface treatments used in the solar industry:

1. Hot-Dip Galvanizing (HDG)

A thick layer of zinc is applied by immersing steel in molten zinc. HDG offers:

Excellent long-term corrosion resistance

Self-healing capability at cut edges

Typical zinc coating thickness: 65μm to 85μm

Ideal for outdoor and coastal installations

2. Zinc-Aluminum-Magnesium (ZAM) Coating

ZAM is a newer type of coating offering:

Superior corrosion resistance (up to 2-3 times better than HDG in salt spray tests)

Thinner coating with better surface finish

High-performance protection in aggressive environments

 

 

3. Powder Coating or Epoxy Painting

These coatings offer both protection and aesthetics:

Applied electrostatically and cured under heat

Often used for custom colors or secondary protection

Requires good surface preparation to ensure adhesion

 

Additional Tips for Corrosion Prevention

Avoid water traps in the design (open profiles, drainage holes)

Use compatible fasteners (e.g., stainless bolts with HDG steel)

Apply touch-up spray (zinc-rich paint) on cut edges during installation

Choose suitable protection based on climate (desert, seaside, humid areas)

 

 

Conclusion

Yes, carbon steel can rust—but with the right surface treatment such as hot-dip galvanizing or ZAM coating, it becomes a reliable and long-lasting material for solar racking systems. When designed and protected properly, carbon steel structures can serve your solar project for 20+ years, even in harsh environments.

If you're looking for a durable, cost-efficient, and well-protected steel pv mounting system, carbon steel with advanced anti-corrosion treatment is a strong choice.

When planning a rooftop solar project, choosing the right mounting system is a key factor for long-term performance and safety. The two most common options are Ballasted (non-penetrating) and Penetrating solar mounting systems. Each offers distinct advantages and limitations depending on your roof type, structural capacity, and installation goals.

This article breaks down the pros and cons of both systems to help you make an informed decision.

 

 

 

What is a Ballasted Mounting System?

Ballasted mounting systems use weight—typically concrete blocks—to hold solar panels in place, without penetrating the roof surface. They are mostly used on flat roofs.

 

Pros:

No Roof Penetration: Ideal for maintaining the waterproof integrity of the roof.

Fast Installation: No drilling or sealing means faster setup and lower labor costs.

Easily Removable: Great for leased buildings or temporary installations.

Simplified Permitting: In some jurisdictions, non-penetrating systems face fewer regulatory requirements.

 

Cons:

Heavy Load: May not be suitable for roofs with limited load capacity.

Wind Sensitivity: Requires more ballast or additional anchoring in high-wind areas.

Limited Tilt Angles: Lower tilt angles can reduce solar efficiency.

Flat Roof Only: Not applicable for sloped or pitched roofs.

 

 

 

What is a Penetrating Mounting System?

Penetrating systems use bolts, screws, or anchors to secure the pv mounting structure directly into the roof or building substructure. They are suitable for flat or sloped roofs made from metal, tile, concrete, and more.

 

Pros:

Stronger Hold: Provides excellent wind resistance, especially for sloped or high-wind areas.

Lightweight System: No need for extra ballast, ideal for roofs with low weight tolerance.

Flexible Tilt Angles: Allows optimal panel positioning for higher energy output.

Broad Compatibility: Works with a wide range of roof types and materials.

 

Cons:

Roof Penetration Risk: Requires proper waterproofing to avoid leakage.

Longer Installation Time: Drilling and sealing add time and complexity.

Ongoing Maintenance: Roof seals should be inspected periodically.

May Require Engineering Approvals: Structural assessments may be needed depending on local codes.

 

 

Quick Comparison Table

Feature	Ballasted Mounting	Penetrating Mounting
Roof Compatibility	Flat roofs only	Flat, sloped, and varied types
Structural Load	Heavy (requires strong roof)	Light (direct anchoring)
Installation Time	Faster	Slower
Roof Waterproofing Risk	Low	Higher (requires sealing)
Wind Resistance	Moderate	High
Tilt Angle Flexibility	Limited	Flexible
Maintenance Requirements	Minimal	Requires inspection

 

Which One is Right for Your Project?

 

Choosing between ballasted and penetrating systems depends on several factors:

Roof type (flat or sloped?)

Structural load capacity

Local weather conditions (especially wind zones)

Installation timeline and budget

Waterproofing and long-term maintenance requirements

In our daily life, water is available by unscrewing the faucet. We hardly realize that water is an important resource.

 

But in many countries, water is as precious as oil. Water scarcity makes poor people even poorer, because they have to pay extremely limited supplies in exchange for the necessities of survival, and water pollution worsens the poverty situation in many countries because the polluted water quality cannot continue life but accelerates the end of life.

 

Can our renewable energy industry contribute to improving poverty in these countries? Yes, we can! Using renewable energy to power water treatment facilities may be a very suitable solution.

 

Xiamen Kingfeels Energy, as a professional solar structure manufacturer, has designed many solar mounting system solutions to fix solar panels, for powering water pumping. And these PV panel installations are very easy for each customer. After being installed, PV systems can be used for pumping water for pumping drinking water, as well as for irrigation of land. We wish our solar mounting can be applicated more and more water pumping station, more and more people can access to a safe and clean water supply.

As solar energy continues to expand across the globe, selecting the right materials for ground-mounted solar systems becomes a crucial decision for developers, EPCs, and asset owners. Two of the most common materials used in solar mounting structures are aluminum and steel—each offering unique benefits and trade-offs. But which one is better for your ground solar project? Let’s explore the key differences to help you make an informed decision.

 

 

1. Strength and Structural Integrity

Steel is significantly stronger than aluminum. It has a higher tensile strength and load-bearing capacity, making it an ideal choice for utility-scale solar farms or sites with harsh environmental conditions, such as heavy snow or strong winds. Galvanized steel (typically hot-dip galvanized) also resists corrosion over time when properly treated.

Aluminum, while not as strong as steel, is still suitable for many ground-mount applications, especially in small to medium-scale projects. It’s generally used in extruded profiles with optimized shapes that provide the necessary strength with less material.

 Choose steel when structural strength under load is a top priority.

2. Corrosion Resistance

Aluminum naturally forms a protective oxide layer, giving it excellent corrosion resistance—especially in coastal or highly humid environments. This makes it a go-to choice for areas prone to rust issues.

Steel, unless it is galvanized or coated, is more susceptible to corrosion. Hot-dip galvanization can significantly extend the lifespan of steel structures, but over time, corrosion might still occur, especially if coatings are damaged.

Choose aluminum for long-term corrosion resistance, particularly in coastal regions.

 

 

3. Weight and Handling

Aluminum is about one-third the weight of steel, making it easier and faster to transport, handle, and install. This can reduce labor costs and construction time on-site.

Steel, being heavier, typically requires heavier machinery and more manpower for installation. However, its rigidity often means fewer supports are needed.

for Choose aluminum for ease of installation and lightweight transport.

4. Cost

Steel is generally more cost-effective than aluminum on a per-kilogram basis. Even with galvanization, steel structures often offer a better price-performance ratio, especially for large-scale installations.

Aluminum is more expensive, but the added cost may be offset by reduced labor, faster installation, and lower maintenance over time.

Choose steel for budget-sensitive projects with robust construction teams.

5. Environmental Impact and Sustainability

Both materials are recyclable, but aluminum has a higher embodied energy (energy used in production). However, because it is lightweight and requires less maintenance, aluminum may have a lower overall lifecycle impact in some cases.

Steel is also widely recycled and has a mature global recycling infrastructure. Some developers may choose materials based on the availability of low-carbon steel or recycled aluminum.

Consider local availability and enviromental priorities when evaluating sustainability.

 

 

 

Final Verdict: Which Is Better?

There’s no one-size-fits-all answer. The best choice between aluminum and steel for ground solar mounting depends on your project size, environmental conditions, budget, and logistics.

 

Criteria	Best Material
Structural Strength	Steel
Corrosion Resistance	Aluminum
Lightweight Installation	Aluminum
Cost-Effectiveness	Steel
Coastal Applications	Aluminum
Large Utility Projects	Steel

 

When in doubt, consult with your solar mounting system supplier or structural engineer. A hybrid approach—using steel for foundations and aluminum for above-ground structures—is also gaining popularity as it combines the strengths of both materials.

As the solar industry continues its rapid expansion, durability and long-term reliability have become critical factors in solar mounting system design. Among the most trusted methods for protecting steel structures in outdoor installations is Hot-Dip Galvanizing (HDG). This treatment greatly enhances the durability of solar mounting systems, especially in ground-mounted applications such as C channel solar structures and single pile solar mounting systems. In this article, we explore how HDG steel adds lasting value to modern solar panel mounting solutions.

 

 

 

What Is Hot-Dip Galvanizing?

Hot-Dip Galvanizing is a process where fabricated steel parts are dipped into molten zinc. This forms a tough, tightly bonded zinc coating that shields the steel from corrosion. The result is a uniform, durable protective layer that extends the life of solar mounting systems, even under harsh environmental conditions.

 

Benefits of HDG for Ground Mount Solar Structures

1. Exceptional Corrosion Protection

Ground-mounted solar systems are often exposed to moisture, UV rays, soil chemicals, and varying temperatures. HDG-treated steel offers superior corrosion resistance, making it ideal for long-term outdoor installations. For example, C channel solar structures benefit from full-surface protection, including weld joints and internal edges.

2. Longevity and Low Maintenance

HDG extends the lifespan of steel components to 25–30 years or more with minimal maintenance. This is particularly valuable for single pile solar mounting systems, which are often used in utility-scale solar farms where maintenance access is limited and costly.

3. Strength and Structural Integrity

HDG enhances not just the lifespan but also the mechanical strength of components by preventing rust-related degradation. C channel solar structures—commonly used in fixed-tilt or adjustable angle arrays—must withstand heavy wind and snow loads. Hot-dip galvanizing ensures their continued performance throughout the project lifecycle.

4. Economic Efficiency Over Time

While HDG may have a slightly higher upfront cost than untreated or painted steel, its long-term durability eliminates the need for frequent repainting, repair, or replacement. This significantly lowers the total cost of ownership for large-scale solar installations.

 

 

 

Real-World Applications in Solar Mounting Solutions

Whether used in agricultural fields, desert zones, or coastal areas, HDG is a key component of reliable solar infrastructure. The following systems gain the most from this treatment:

C Channel Solar Structure (also known as C-Steel Ground Mounting System): These steel structures form the core frame of many ground-mount PV systems. Their C-shaped profile offers high strength and easy installation. HDG coating preserves their structural properties and prevents rust, ensuring project longevity.

Single Pile Solar Mounting System: Often deployed in utility-scale projects, this design relies on vertical posts driven into the ground. HDG treatment protects these load-bearing elements from soil corrosion and weathering over time.

 

 

Conclusion

Hot-Dip Galvanizing is a critical factor in the long-term performance and reliability of ground-mounted solar systems. Whether you’re deploying a single pile solar mounting system or a C channel solar structure, HDG steel solar mounts offer a resilient, cost-effective solution for modern solar panel mounting solutions.

By investing in galvanized steel, solar developers and EPCs not only safeguard their infrastructure but also align with sustainable and low-maintenance engineering practices.
