Channel Steel Product Description
Product Introduction
Channel steel is a long steel product with a groove-shaped section, which is an economical and high-efficiency section profile. It is widely used in building structures, vehicle manufacturing, curtain wall supports, mechanical frames and various engineering brackets. Featuring excellent bending resistance, high structural strength, convenient installation and high cost performance, it can be processed by hot rolling, galvanizing, cutting, punching and other methods according to customer requirements.
