Galvanized flat iron is a kind of steel used for lightning protection and grounding.

Steel steel is one of the four major steel varieties (plates, tube, type, silk). Depending on the shape of the section, the type of steel is divided into simple section steel and complex cross -sectional steel (different -type steel). The former refers to Fang Steel, Round Steel, Flat Steel, Clason Steel, Hexagon Steel, etc., and the latter refers to work steel, slot steel, rails, window frame steel, curved steel, etc.
Founded steel-steel with square sections, divided into hot rolling and cold rolling; hot-rolled square steel edges of 5-250mm; cold-tilled square steel edges 3-100mm.
Round steel-round section steel, divided into three types: hot rolling, forging and cold pull. The supply is also called hot rolled bars. Forging round steel is thicker and use it as a shaft. The diameter of the cold-pulling steel is 3-100 mm, and the size accuracy is high.
Flat steel-12-300mm wide, 4-60mm thick, and the cross section with a slightly pure side steel. Flat steel can be a finished steel, or a thin plate for welding pipes and a thin sheet for tubing.
Corner steel -divided corner steel and no corner steel. The specifications of corner steel are represented by the sizes of edge length and thickness. The corner steel specifications are usually No. 2-20, that is, the number of centimeters of the edge length. For example, corner steel such as No. 5 refers to corner steel with a length of 5cm (50mm). The same number of corner steel often has 2-7 different edges.
Reinforced steel is not steel
