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.
