Material: Square steel is usually made of carbon steel or low alloy high strength structural steel. Common materials include Q235 and Q345.
Application areas: Square steel is widely used in building structures, machinery manufacturing, vehicle manufacturing, metal processing and other fields. They are used as supporting structures, frame structures, pillars and other parts that require high strength.
Square steel is a type of steel that is square in cross-section and has good strength and stability. The shape of square steel makes it perform well when subjected to bending and shear forces, making it suitable for a variety of engineering and manufacturing applications. Square steel can be hot-rolled square steel or cold-drawn square steel, the former is generally used in most building and structural applications, while the latter is used in applications that require more precise dimensions.
Material type:
Steel substrate: usually hot-rolled or cold-drawn steel
Steel standards:
Chinese standards: GB/T 709 (hot-rolled square steel), GB/T 1220 (cold-drawn square steel)
Steel models:
Q235: carbon steel with a yield strength of 235 MPa
Q345: low-alloy high-strength structural steel with a yield strength of 345 MPa
Cross-sectional dimensions:
Side length:
Hot-rolled square steel: Common range is from 20mm to 200mm
Cold-drawn square steel: Common range is from 10mm to 100mm
