Pre-galvanized C Section Products Advantages:

●C section steel matches to excellent plasticity and flexibility, high structural stability and more sensitive construction. It is widely used for the solar mounting structure big projects with more than thousands of MW.


●Pre galvanizing can reach an average of 40μm~70μm (zinc layer thickness according to customer's drawing requirements). 


●The raw materials use POSMAC, Nippon Steel, domestic materials normally use Rizhao Steel, HBIS, JISCO Steel and SHOUGANG Group, the original material brands are selected according to the requirements of different countries and customers. Common material selection standard is SS275JR, SS355JR.

Packing of C Section Products

Normally we will choose the PET STRAP with wooden base, STEEL STRAP or STEEL STRAP WITH NYLON STRAP for packing, which is safe enough for transportation. If the customer have special requests, we can do OEM as per customers’ requirements.

Advantage of c section steel:

C section steel matches to excellent plasticity and flexibility, high structural stability and more sensitive construction. It is widely used for the solar mouting structure big projects with more than thousands of MW.

The steel structure by c purlins is enough light comparing with the concrete structure, moreover self-weight C profile itself is more lighter, so the self-weight of whole steel structure is reduced indeed. But still it is strong enough for the supporting of the solar panels.

Solar mounting structure by galvanised c section purlins could realize simple construction, lower the cost and less demand for construction requirement.

Introduction of factory

The Factory covers an area of 6,000 square meters with the most advanced equipment. Annual Steel production reached 500,000 tons. There are 10 production lines for profile products. Quality and delivery can be ensured for each order. We have the records that delivery a project c profile of 200 tons in 2 weeks. And the zinc layer reach to average 120um.
