S275JR square tubing is made of non-alloy structural steel. In its name, "S" represents structural steel, "275" indicates a minimum yield strength of 275 MPa, and "JR" signifies its specific impact toughness at room temperature. This material is typically manufactured into square sections using processes such as hot rolling or cold drawing, featuring uniform wall thickness and straight edges.
Regarding dimensions, S275JR square tubing is available in various combinations of side lengths and wall thicknesses. Common side lengths range from 20 mm to 400 mm, while wall thickness depends on specific application requirements. Different specifications of square tubing have varying weights per unit length, directly impacting material usage and cost.
In terms of applications, S275JR square tubing is primarily used in building structures, machinery manufacturing, vehicle frames, and general engineering structures. In construction, it is commonly used in beam-column systems, roof trusses, and supporting components; in machinery manufacturing, it can be used for equipment frames and protective structures; and in vehicle manufacturing, it is suitable for chassis and body frames.
