Q235B is a carbon structural steel under the Chinese GB/T700 standard. It has a low carbon content, which makes it have good plasticity and welding performance. Its yield strength is 235MPa, tensile strength is 370-500MPa, and elongation is high, which can meet certain plastic deformation requirements.
Rich and diverse dimensions: can be customized according to different needs. Smooth surface, seamless inner and outer walls: can provide better fluid transmission and thermal conductivity. Wide selection of materials: suitable for various environments and working conditions. High strength and corrosion resistance: long service life.
The cross section of the round tube is circular, the pressure distribution is uniform, and it has good pressure resistance. The round tube is electroplated or hot-dip galvanized, which can effectively prevent the corrosion of the pipe and extend the service life. The round tube has a regular shape, a smooth inner cavity without burrs, and can smoothly transport liquids, gases, solids and other substances.
Black square tube, also known as black square tube, is a common building material, usually made of hot-rolled or cold-drawn steel strip. Its surface is usually treated with rust prevention to prevent oxidation and corrosion.
Structural steel is widely used in the fields of construction, bridges, machinery manufacturing, etc. S280GD+Z, S350GD+Z and S450GD+Z are three different types of high-strength structural steels, which differ in hardness, yield strength, tensile strength, etc., so the prices will also be different.
Galvanized square pipe refers to galvanized square pipe, which is a steel pipe with a square cross-section and the surface is galvanized to enhance corrosion resistance.
