Introduce	. I-shaped steel is shaped like an I, having the same upper and lower edges and half the body. . At first, it is usually dark green, but it is often left outdoors so it appears yellow clay quickly. . Body height from 100-800mm wing width from 50-400mm. Common length is 6m or 12m




Uses	Application in construction of prefabricated workshops, mechanical industry, crane beams, platforms, and other bearing structures, ...



Steel Mark	SS400, GOST, JIS, Q, BS, KS, TCVN
Origin	Origin: China, Korea, Taiwan, Japan, Vietnam ...
