Product Description
Cold Rolled Welded Hollow Square Rectangular Carbon Steel Tube
Cold rolled welded hollow square rectangular carbon steel tubes are a popular choice for a wide range of applications due to their strength, durability, and versatility. They are commonly used in the construction industry, as well as for the manufacture of furniture, vehicles, and other industrial products. In this article, we will explore the characteristics, benefits, and applications of cold rolled welded hollow square rectangular carbon steel tubes.
Characteristics
Cold rolled welded hollow square rectangular carbon steel tubes are made from carbon steel that has been processed using a cold rolling method. This results in a smoother and stronger tube with better dimensional accuracy and straightness compared to hot rolled tubes. The welding process used to join the edges of the tube results in a seam that is less visible and stronger than the joint produced by other methods.
Benefits
Cold rolled welded hollow square rectangular carbon steel tubes offer several benefits over other types of tubes. First and foremost, they are stronger and more durable, making them suitable for use in high-stress applications. They are also more resistant to bending and twisting, which makes them ideal for use in structural applications. The smooth and straight edges of cold rolled welded hollow square rectangular carbon steel tubes make them easier to work with, allowing for easier cutting, drilling, and welding. Finally, they are more affordable than some other types of tubes, making them a popular choice for cost-conscious industries.
Applications
Cold rolled welded hollow square rectangular carbon steel tubes are used in a wide range of applications due to their strength and versatility. In the construction industry, they are used for the manufacture of buildings, bridges, and other structures. They are also used in the production of furniture, such as tables and chairs, as well as in the manufacture of bicycles and other vehicles. Cold rolled welded hollow square rectangular carbon steel tubes are also used in the industrial sector for the production of machinery, equipment, and other products.
One of the key advantages of cold rolled welded hollow square rectangular carbon steel tubes is their suitability for use in structural applications. They are used as support beams, columns, and other load-bearing structures in the construction industry. The strength and durability of these tubes make them ideal for use in high-stress applications where other types of tubes may not be suitable.
Cold rolled welded hollow square rectangular carbon steel tubes are also commonly used in the manufacture of furniture and other consumer goods. Their strength and durability make them ideal for use in tables, chairs, and other pieces of furniture that need to support weight and withstand regular use.
In the industrial sector, cold rolled welded hollow square rectangular carbon steel tubes are used for the production of machinery and equipment. They are used in the manufacture of agricultural machinery, construction equipment, and other heavy-duty equipment that requires strong and durable materials.
In conclusion, cold rolled welded hollow square rectangular carbon steel tubes are a popular choice for a wide range of applications due to their strength, durability, and versatility. They are used in the construction industry, as well as for the manufacture of furniture, vehicles, and other industrial products. With their smooth edges, dimensional accuracy, and strong welding seams, these tubes offer several benefits over other types of tubes, making them an ideal choice for cost-conscious industries that require reliable and efficient solutions.
Rectangular Cold Rolled Tube
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.
