Galvanized I-beam, also known as steel beam, is a section shape of long steel. It is divided into ordinary steel, light steel and H-beam steel. Common beam and beam of the wing root to edge thinning, has a certain Angle, ordinary beam and beam model is to use the high waist centimeters Arabic Numbers, web and flange and the thickness of the flange width different specifications to waist high (h) * waist leg width (b) (d) says the number of blessing, such as "sewing worker 160 x 88 x 6", said the waist is 160 mm high, The width is 88mm, with 6mm ordinary beam thickness of the leg.

Galvanized angle steel is divided into hot-dip galvanized angle steel and cold-galvanized angle steel. Hot-dip galvanized angle steel is also called hot-dip galvanized angle steel or hot-dip galvanized angle steel. The cold galvanized coating mainly ensures the full contact between the zinc powder and the steel through the electrochemical principle, and generates the electrode potential difference for anti-corrosion.
