Welding and assembling are the two main connection methods for solar mounting structure.

Welding has lower requirements for angle steel. And it has the advantage of lower price, better connection, firmer, so it’s more common applications on solar mounting bracket. However, the problem with welding is that the joints are prone to corrosion and the maintenance cost will be high. Anti-corrosion work must be carried out every year. Therefore, the welding cost is high. In addition, welding in field installations consumes a lot of power, which also increases costs. Although welding has low material requirements and good connection effect, the process is slightly rough, the bracket is not beautiful.

Channel steel is gradually replacing these welded brackets to overcome the above problems. As a kind of splicing bracket, the finished channel steel bracket does not need welding on site, and can be directly spliced by bolts on site. It is fast in installation, beautiful in appearance, very durable and easy to adjust.

Corigy’s solar mounting structure adopt channel steel, which can greatly reduce the cost for customer.
