Main products
Hot rolled square steel
Hot rolled square steel, is steel that is rolled or machined into a square cross section. Square steel can be divided into two types: hot-rolled and cold-rolled; hot-rolled square steel has a side length of 5-250mm and cold-drawn square steel has a side length of 3-100mm.
Square Steel
[square steel] steel rolled or worked into a square cross section
The density of steel is: 7.851g/cm3
Calculation of the theoretical weight of steel
The unit of measurement for calculating the theoretical weight of steel is the kilogram (kg). The basic formula is.
W (weight, kg) = F (cross-sectional area mm2) × L (length, m) × ρ (density, g/cm3) × 1/1000
Square steel can be divided into two types: hot-rolled and cold-rolled; hot-rolled square steel with side lengths of 5-250mm and cold-drawn square steel with side lengths of 3-100mm.
Cold-drawn square steel
Cold-drawn square steel refers to cold-drawn steel with square shape of forging
Cold-drawn square steel refers to cold-drawn steel with square shape.
Cold drawn steel is forcibly stretched steel under room temperature conditions with tensile stress exceeding the yield point strength of the original steel bar to produce plastic deformation of the steel bar in order to improve the yield point strength of the steel bar and save steel for the purpose.
Cold drawing is the use of cold extrusion technology, through the precise die, pull out all kinds of high-precision, smooth surface round steel, square steel, flat steel, hexagonal steel and other shaped steel.
The concept of cold drawing of steel bars: to save steel, improve the yield strength of steel bars for the purpose of tensile stress beyond the yield strength and less than the ultimate strength to stretch the steel bars, so that the practice of plastic deformation is called cold drawing of steel bars.

Product specification
Cold-drawn bright square steel: 3×3mm-80×80mm
Twisted square steel
The diameter of twisted square steel is 4mm – 10mm, the common specifications are 6*6mm and 5*5mm, which are twisted from 8mm and 6.5mm diameter coil elements drawn and twisted respectively.
Material: Q235.
Torque: standard torque of 120mm/360 degrees, the standard torque is relatively beautiful and practical.
Use: Widely used in steel grating, steel structure or reinforced concrete to replace rebar.
Advantages: twisted and twisted square steel increases the tensile force of the structure, beautiful appearance, greatly reducing capital costs; sharp edges, accurate diameter.
