Core Advantages

Why ZAM Steel Solar Mounting Outperforms Conventional Systems

SLPV700 series mounting systems use zinc-aluminum-magnesium coated high-strength steel — the material choice for solar projects that demand long-term reliability and lower total cost.

5× Better Corrosion Resistance

ZAM coating delivers 5× longer service life than hot-dip galvanized steel in coastal, humid, and high-chloride environments. No need for additional anti-corrosion treatment or frequent maintenance.

Lighter Weight, Lower Cost

High-strength ZAM steel (yield strength 550–700 MPa) means thinner sections with no strength compromise. Lighter structure, lower freight, easier installation — reduced total mounting cost.

Faster Installation

Optimized structural design with pre-assembled components. Fewer parts, simpler installation process — reduces on-site labor cost and project timeline significantly.

Commercial Rooftop Mounting

Lightweight, high-strength rooftop mounting solutions for commercial and industrial buildings. Ballasted or fixed-penetration systems designed for various roof types and load conditions.

03 — COASTAL

Coastal & High-Corrosion Environments

Zn-Al-Mg coated steel is the natural choice for seaside, tropical, and desert solar installations. No additional anti-corrosion coating needed — reducing both material cost and maintenance requirements.

04 — CUSTOM

Custom Mounting Design

Send your project specifications, site conditions, or current design. We provide material substitution recommendations and structural optimization for cost reduction.

05 — COMPONENTS

Mounting Components Supply

Zn-Al-Mg coated high-strength steel rails, clamps, splices, and hardware. Compatible with standard solar module frame dimensions. Available for bulk orders and long-term supply agreements.

06 — ENGINEERING

Structural Engineering Support

Structural load calculations, wind speed analysis, and foundation recommendations. Help your engineering team select the right mounting solution for your specific site conditions.

Material Advantage

Why Zn-Al-Mg Coated Steel is the Future of Solar Mounting

Zinc-Aluminum-Magnesium (ZAM) coated steel is revolutionizing solar mounting systems in demanding environments where conventional hot-dip galvanized steel falls short.

Self-Healing at Cut Edges

Zn-Al-Mg coating contains aluminum which creates a protective barrier at cut edges and scratches — the weak points of standard galvanized coatings. Critical for on-site cutting and installation.

Superior Chloride Resistance

Chloride ions from coastal air and salted environments rapidly degrade standard galvanized coatings. Zn-Al-Mg alloy composition provides exceptional resistance to chloride-induced corrosion.

Thinner, Lighter, Cost-Effective

High-strength Zn-Al-Mg coated steel (550–700 MPa yield strength) allows thinner profile walls while meeting structural requirements. Result: lighter structures, lower freight cost, easier handling.

Long-Term Lifecycle Value

No repainting, no anti-corrosion maintenance, no early replacement. Zn-Al-Mg coated mounting systems maintain structural integrity for 25+ years — matching solar panel lifespan.

FAQ

Common Questions About Solar Mounting

Yes. We support custom manufacturing based on project specifications, site conditions, or engineering drawings. Send your requirements and our technical team will provide structural recommendations and a detailed quotation within 24 hours.

Zinc-Aluminum-Magnesium (Zn-Al-Mg) coating provides up to 5× better corrosion resistance than standard HDG coating, especially in coastal and high-chloride environments. It also has self-healing properties at cut edges. While Zn-Al-Mg has a slightly higher upfront material cost, the total lifecycle cost is significantly lower due to reduced maintenance and longer service life.

MOQ depends on the product type and specifications. We welcome both pilot orders (trial runs) and full-container or full-truck orders for large solar projects. Please send your project details for a specific quotation.

Yes. With your project location (wind speed, snow load), site conditions, and module specifications, we can provide structural load calculations and foundation recommendations as part of our technical support service.

For first orders, we typically accept T/T 30% deposit + 70% against copy of B/L. For established partners and large project orders, L/C or payment terms can be discussed. All orders include SGS quality inspection reports before shipment.
