How we produce the steel solar photovoltaic mounting structure for a 500 MW project

 

Recently, Corigy just finished an order for a 500MW photovoltaic solar mounting bracket. The solar racking adopt Zn-Al-Mg steel material which the corrosion resistance is 5-10 times that of traditional galvanizing. And it is especially suitable for high humidity and coastal environments.

Raw Material Preparation

Substrate Selection: High-strength cold-rolled steel coil (S350GD + ZM275) is used to ensure mechanical properties.

Coating Treatment: The substrate is hot-dip coated with zinc-aluminum-magnesium (Zn-Al-Mg alloy, typically composed of Zn-11% Al-3% Mg). The coating thickness is typically 60-150g/m², providing excellent corrosion resistance and self-healing capabilities.


Uncoiling & Leveling

Uncoiling: Steel coil is fed into the production line via decoiler.

Leveling: Multi-roller leveler eliminates internal stresses and ensures flatness.

 

Progressive bending through a series of rollers to form C-shaped cross-sections

 

Automated hemming process

Imported high-precision hemming equipment is used, and the forming angle is precisely controlled by a CNC system. A single-step forming process ensures structural strength and reduces weld joints. The forming accuracy error is controlled within ±0.5mm, ensuring a perfect fit during subsequent assembly.
