Cold Rolled Square, Rectangular, Round Tubes for Furniture, Fitness Equipment, Store metal Fixture...etc.
Cold Rolled Square Tube refers to cold-drawing, cold-bending, cold-drawing and other cold processing at normal temperature to process steel plates or steel strips into various types of steel. Advantages: fast forming speed, high output, and no damage to the coating, can be made into a variety of cross-sectional forms to meet the needs of the use conditions; cold rolling can cause a large plastic deformation of the steel, thereby improving the yield of the steel point.
Rectangular Cold Rolled Tube is a strong, resilient, tough and durable construction material option that can be used for a nearly endless amount of applications. The close tolerances, dense structure and good finishing abilities allow rectangular steel tubing to be utilized either statically or dynamically. Rectangular structural steel tubing can withstand extreme temperatures, pressures and an array of changing climate disparities, while being used in both industrial and domestic settings.

Rectangular Steel Tubing Properties & Dimensions
ASTM A500 verified rectangular steel tubing maintains established, clearly defined seams that are not located anywhere within the curvature of the tube. This type of quality control allows for a consistently well-maintained product that is strong and can resist stress from all directions, while being able to easily connect to other structural shapes. A 10.6 radius of corners is also preserved so the corner section of the rectangular steel tubing does not exceed the set parameter of specified wall thickness.
It is worth noting that some of the structural steel items may contain the abbreviation "HSS," which stands for Hollow Structural Section. Essentially, this means that the manufactured product is a square or rectangular steel tube that meets the structural specifications of ASTM A500 Grade B or C. If, however, you see the ASTM A500 designation on a print without a corresponding grade, please ask your engineer for additional clarification, since the minimum tensile strength of Grade C is higher than that of Grade B.
Rectangular Structural Steel Tubing Material Properties
Steel is composed of mainly iron and carbon with smaller amounts of other elements that makeup the minority of the material structure. Nickel and manganese are often added to raw steel compositions to provide increased tensile strength and to promote increased stability within the iron-carbon solution. In addition, chromium increases the hardness of the steel, while the melting temperature, and vanadium also increases hardness while making it less prone to metal fatigue.

Short Description |
Cold rolled square steel pipes or cold rolled black annealed square tubes is made by the cold rolled sheets or coils, its name comes from the scaly, dark-colored iron oxide coating on its surface. It's used in applications that don't require galvanized steel. |
