Compared with I-beam, this product comes with the merits of high precision, lightweight and high section modulus. This product includes HW wide flange, HM medium flange, HN narrow flange, etc. Thanks to their high stability, high plasticity and ductility, they are used for buildings that need to bear a heavy load and to withstand strong vibration and natural calamity, particularly those constructions located in earthquake belt.
