Four Kinds Of Steel Galvanized Yuan Flat Iron

Section steel is one of the four major steel varieties (plate, tube, profile and wire). According to the section shape, the section steel is divided into simple section steel and complex section steel (special section steel). The former refers to square steel, round steel, flat steel, angle steel, hexagonal angle steel, etc., while the latter refers to I-beam, channel steel, rail, window frame steel, bending section steel, etc.
Square steel - the steel with square section, which is divided into hot rolling and cold rolling; the side length of hot-rolled square steel is 5-250mm; the side length of cold-drawn square steel is 3-100 mm.
Round steel - round section steel, divided into hot-rolled, forged and cold drawn three kinds, hot-rolled round steel diameter of 5-250 mm, of which 5-9 mm is commonly used as raw material for drawing steel wire, called wire rod; due to the coil supply, it is also called hot-rolled wire rod. Forged round steel is straight and thick, and is used as shaft blank. The diameter of cold drawn round steel is 3-100 mm, with high dimensional accuracy.
Flat steel - 12-300 mm wide, 4-60 mm thick, cross-section and slightly pure edge. Flat steel can be finished steel, can also be used as welded pipe blank and thin slab for laminated sheet.
Angle steel - divided into equal angle steel and unequal angle steel. The specification of angle steel is expressed by side length and side thickness. Usually the angle steel specification is 2-20, that is, the centimeter of side length. For example, No.5 equal leg angle steel refers to the angle steel with side length of 5cm (50mm). The same horn steel often has 2-7 different side thicknesses.
