Project Background
A solar mounting system manufacturer from Southeast Asia was looking for a reliable supplier of corrosion-resistant steel components for a ground-mounted photovoltaic project.
The project required structural materials that could withstand long-term outdoor exposure in a humid environment while maintaining stable mechanical performance during installation and operation.
Compared with traditional galvanized steel, the customer was interested in Zn-Al-Mg coated steel solutions due to their improved corrosion resistance and better edge protection after fabrication.
Customer Requirements
The customer's main requirements included:
| Requirement | Details |
|---|---|
| Product | Zn-Al-Mg coated C Channel / Solar Mounting Bracket |
| Material | S250GD+ZM |
| Application | Ground-mounted PV support structure |
| Surface Treatment | Zn-Al-Mg alloy coating |
| Processing | Roll forming, punching and cutting |
| Requirement | Stable quality, accurate dimensions, export packaging |
The customer required a supplier who could provide not only steel material but also customized processing according to their solar mounting system design.
Our Solution
Based on the project requirements, GNEE STEEL provided S250GD+ZM Zn-Al-Mg coated steel coil as the raw material and processed it into customized galvanized C channels for photovoltaic mounting applications.
The supplied solution included:
- S250GD+ZM structural steel material
- Customized C channel profiles
- Precision punching according to drawings
- Required cutting lengths
- Export-standard packaging
The Zn-Al-Mg coating provided enhanced corrosion protection, making the components suitable for long-term outdoor applications.
Production and Quality Control
During production, each batch was inspected to ensure compliance with customer requirements.
Quality inspection included:
- Material grade verification
- Thickness measurement
- Dimension inspection
- Surface quality inspection
- Coating weight testing
Before shipment, finished C channels were properly bundled and protected to prevent deformation and surface damage during ocean transportation.
