while rigorous quality control and green production ensure international standards.
C-beam is a kind of cold-formed steel with “C” cross-section, also known as C-channel and C-purlin. Its unique shape is similar to the letter “C”, with horizontal flanges at the top and bottom, and vertical webs to provide strength and stability. So it is widely used in construction, machinery, photovoltaic bracket, etc. It is characterized by light weight, high strength load bearing and easy installation.
