Field & Engineering Micro-Answers
Direct structural engineering answers to the most searched Google questions regarding Ground Mount System
Why choose aluminum over galvanized steel for ground solar purlins?
Aluminum offers zero maintenance, eliminates rust at cutting/drilling edges, is three times lighter for cheaper freight, and delivers superior recyclability under EU CBAM rules.
How is galvanic corrosion prevented between steel posts and aluminum purlins?
UV-resistant composite separation washers and isolation gaskets are inserted at all steel-to-aluminum contact surfaces to eliminate electrolytic action.
What column spacing (span) can be bridged with 6005A-T6 rails?
Our high-moment aluminum purlins safely span 3.20m to 3.80m between driven posts, reducing the number of steel piles needed per MW.
Does the purlin design shade bifacial module rear sides?
No. Slim-profile purlins and optimized rail placement minimize underside shading, preserving up to 25% bifacial albedo gain.
What packaging is utilized for MW-scale containerized deliveries?
Purlins are pre-bundled in steel-strapped wooden skids (ISPM-15 compliant) sized for 40ft High Cube containers and curtain-side mega-trailers.
What is SolarAlu annual supply capacity for utility projects?
With 12,000 metric tons annual extrusion capacity, we reliably deliver 200+ MW of solar mounting aluminum per year.

Why EN AW-6063-T6 Structural Aluminum Over Hot-Dip Galvanized Steel?
Photovoltaic mounting structures are 25 to 30-year infrastructure assets. Specifying extruded aluminum over heavy galvanized steel delivers decisive advantages in structural rooftop safety, installation speed, and zero lifetime maintenance.
| Engineering Criterion | SolarAlu 6063-T6 / 6005A Anodized Aluminum | Hot-Dip Galvanized Steel (HDG) |
|---|---|---|
| Specific Weight & Rooftop Dead Load |
2.70 g/cm³ (~1.8 - 2.5 kg/m² structural load)
3x lighter than steel; preserves structural load reserves on large-span industrial roofs without expensive building reinforcement. |
7.85 g/cm³ (~6.0 - 9.0 kg/m² structural load)
Heavy dead weight; frequently violates building deflection limits on lightweight sandwich and trapezoidal roofs. |
| Atmospheric Corrosion & Lifespan |
25+ Years Maintenance-Free (Qualanod 15µm/20µm)
Forms an impervious self-healing aluminum oxide layer; zero corrosion in marine seaside (C4/C5) and industrial chemical atmospheres. |
Corrosion Initiates within 5–8 Years
Field cutting and bolt drilling damages the zinc barrier layer; rust run-off stains PV glass and demands periodic repainting. |
| Installation Speed & Labor Cost |
45% - 50% Faster Job Site Assembly
Pre-engineered T-Slot channels allow rapid snap-in fasteners; zero on-site cutting, zero welding, and minimal crane hoisting required. |
Heavy Labor & Slower Progress
Heavy manual lifting on roofs, complex multi-piece bolting, and awkward alignment double the on-site mechanical installation labor hours. |
| Galvanic Compatibility with PV Modules |
100% Metallurgical Compatibility
Solar module frames are also manufactured from anodized aluminum; zero electrical potential difference, preventing bimetallic contact corrosion. |
Bimetallic Galvanic Cell Risk
Direct steel-to-aluminum contact forms a galvanic cell in humid conditions, corroding the module frame and voiding panel warranty. |
| End-of-Life Residual Asset Value |
80% - 85% Scrap Residual Value
Aluminum is infinitely recyclable without property degradation, representing a liquid financial asset at decommissioning. |
Low Residual Scrap Value
Corroded steel scrap value is negligible and often does not cover the crane and disassembly labor costs. |
