Flat steel refers to steel with a width of 12-300mm, a thickness of 3-60mm, a rectangular cross-section and a slight blunt edge. Flat steel can be finished steel, and can also be used as blanks for welded pipes and thin slabs for stacked sheets. Main application: Flat steel can be used as a finished material to make hoop iron, tools and mechanical parts, and it can be used as a house frame structure and escalator in construction.
Galvanized flat steel refers to galvanized steel with a width of 12-300mm, a thickness of 4-60mm, a rectangular section and a slight blunt edge. Galvanized flat steel can be used as a finished product to make hoop iron, tools and mechanical parts, and it can be used as a building frame structure, escalator and so on.

Square steel bar, solid bar. Hot-rolled square steel refers to steel that is rolled or processed into a square section. Square steel can be divided into hot-rolled and cold-rolled; Cold-drawn square steel refers to cold-drawn steel that is forged in a square shape.

Hexagonal steel is a kind of section steel, also known as hexagonal bar, and the cross-section is a regular hexagonal bar. Hollow hexagonal steel is widely used in various structural parts, tools and mechanical parts. Compared with the round tube, the hexagonal tube generally has a larger moment of inertia and section modulus, and has a larger resistance to bending and torsion, which can greatly reduce the weight of the structure and save steel.

Carbon steel hexagonal bar, also known as carbon steel hexagonal steel, is a type of section steel, which is a long strip of solid steel with a regular hexagonal cross-section.
