S235JRH Sqaure Tubes Cold Formed

Xinsteel keeps all kinds of stock cold formed rectangular tubes s235jrh,cold forming rectangular hollow sections S235JRH and rectangular pipes cold form finished S235JRH.Square hollow sections is inherently strong and efficient.These sections give buildings a better strength-to-weight ratio than those using comparable steel,concreteor timber products.
