Product Description
Carbon steel square steel is a solid long strip of steel with a square cross-section. Square steel is made from steel ingots, billets or steel through pressure processing. Square steel can be divided into two types: hot-rolled and cold-rolled; hot-rolled square steel refers to steel that is rolled or processed into a square section. Square steel is generally used in light steel structures, such as steel roof trusses, civil housing skeletons, etc.

The difference between round steel and other steel bars
1. The appearance is different, the round steel has a smooth appearance, no texture and no ribs, and other steel bars have engraved or ribbed surface appearance, which causes the bonding force between the round steel and the concrete to be small, while the other steel bars and the concrete have less adhesion. Great adhesion.
2. The composition is different. Round steel (grade 1 steel) belongs to ordinary low carbon steel, and other steel bars are mostly alloy steel.
3. The strength is different, the strength of the round steel is low, and the strength of other steels is high, that is, the round steel with the same diameter can withstand less tensile force than other steel bars, but the plasticity of the round steel is higher than that of other steel bars. Strong, that is, the round steel has a large deformation before being broken, while the deformation of other steel bars is much smaller before being broken.
