What is square steel？

Square steel: It is solid, a bar. Different from Square Tubes, it is hollow and belongs to pipes.

Steel village: It is a material made of various shapes, sizes and performances required by steel ingots, billets or steel through pressure processing. Steel is an important material indispensable for national construction and the realization of the four modernizations. It is widely used and has a wide variety. According to the different cross-sectional shapes, steel is generally divided into four categories: profiles, plates, pipes and metal products. In order to facilitate the organization of steel production, order supply and good management, it is divided into heavy rails, light rails, large steel, medium steel, small steel, Steel Cold-bent steel, high-quality steel, wire, medium and thick steel plate, thin steel plate, electrical silicon steel sheet, strip steel, seamless steel pipe steel, welded steel pipe, metal products and other varieties.
Square steel calculation formula
Similar bars include round steel, hexagonal steel, and octagonal steel. See national standard GB/T702-2008 Hot rolling, steel bar size, shape, weight and allowable deviation
Hot-rolled square steel: refers to steel rolled or processed into a square cross-section. Square steel can be divided into 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 is steel rolled or processed into a square cross-section
The density of steel is: 7.851g/cm3

Theoretical weight calculation of steel
The unit of measurement for theoretical weight calculation of steel is kilogram (kg).
The basic formula is: W (weight, kg) = F (cross-sectional area mm2) XL (length, m) x p (density, g/cm3) X1/1000 Square steel can be divided into 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. Cold drawn square steel
Cold drawn square steel refers to cold drawn steel with a square forged shape.
Cold drawn steel is to stretch the steel bar at room temperature with a tensile stress exceeding the original steel bar yield point strength, so that the steel bar produces plastic deformation to achieve the purpose of improving the steel bar yield point strength and saving steel.
Cold drawn steel is to use cold extrusion technology to draw various types of high-precision, smooth-surfaced round steel, square steel, flat steel, hexagonal steel and other special-shaped steel through precise molds.
Concept of steel bar cold drawing: The practice of stretching steel bars with a tensile stress exceeding the yield strength but less than the ultimate strength to produce plastic deformation for the purpose of saving steel and improving the yield strength of steel bars is called steel bar cold drawing.
Stainless steel square steel: rolled or processed into a square section

Theoretical weight calculation of steel
The unit of measurement for theoretical weight calculation of steel is kilogram (kg).
The basic formula is: W (weight, k:) = F (cross-sectional area mm2) XL (length, m) Xp (density, g/em3) x1/1000
Product Specifications
Stainless steel square steel is mainly used in fine decoration, such as doors and windows.
Product Specifications
Cold-drawn bright square steel: 3x3mm-80x80mm
Twisted square steel
The diameter of twisted square steel is 4mm-10mm, and the commonly used specifications are 6*6mm and 5*5mm, which are twisted by wire drawing of 8mm and 6.5mm diameter coils respectively.
Material: coil Q235.
Torque: The standard torque is 120mm/360 degrees, which is relatively beautiful and practical.
Use: Widely used to replace threaded steel in steel gratings, steel structures or reinforced concrete.
Advantages: Twisted square steel increases the tensile force of the structure, has a beautiful appearance, and greatly reduces capital costs: clear edges and corners, and accurate diameter.
