Photovoltaic bracket c purlin is used as the purlin or rail support in roof and ground photovoltaic mounting systems. It connects columns, base brackets, clamps, and module rails. The advantage is that the section, hole layout, length, and surface finish can be matched to the bracket drawing, so the C purlin arrives ready for bolt connection and does not need site punching.

Product Advantages
1) Photovoltaic bracket c purlin can be punched before surface treatment, so bolt holes and slots keep protected edges.
2) The 41-series support sections fit many PV brackets, while C100-C300 sizes can be used for heavier steel frames.
3) Q235B and Q355B options let the buyer match roof load, ground span, and wind design.
Main Applications
Used in rooftop PV supports, ground PV structures, carport PV frames, and farm PV support rows.
Suitable for purlin positions that connect to clamps, bases, and rail parts.
Production Process
Coils or strips are roll formed into C section, punched or slotted, cut to length, and treated with galvanized or ZAM surface.
Bundle marks can show project row, length, and section size for site sorting.
Packaging and Transport
Small parts are packed by set or by size label. Long sections are bundled with end protection and pallet marks.
When a shipment includes several close sizes, labels show diameter, length, thickness, or section code.
