Round Electric Welded Steel Tubing

Round tubing is renowned for its strength-to-weight ratio and resistance to buckling, making it well-suited for applications involving high loads and pressure, such as hydraulic cylinders and roll cages. Additionally, its smooth, continuous surface facilitates welding and bending processes. Strong, durable and cost effective.

Product Description

Round carbon steel tubing is a versatile, durable hollow section manufactured from carbon steel. It is widely used across structural, mechanical, and industrial applications due to its strength, weldability, and cost effectiveness.

Benefits of Round Electric Welded Steel Tubing

High strength-to-weight ratio; excellent weldability; cost-effective compared to alloy materials; consistent dimensional accuracy; suitable for a wide range of structural and mechanical uses.

High Strength-to-Weight Ratio: Lightweight but strong and stiff tubing.
Uniform Wall Thickness
: The welded tubing maintains consistent thickness, resutling in better durability. 
Cost-Effective:
Welded is more economical than seamless tubing, especially for larger diameter and thicker wall thicknesses.
Versatile: 
ERW tubing can be used in a wide range of applications, including construction, automotive, agriculture, and manufacturing.
Customizable: ERW tubing can be easily cut, bent, and welded, allowing for customization to meet specific project requirements.
Smooth Surface Finish: The welding process results in a smooth surface finish, which can reduce friction and improve the appearance of finished products.

Applications of Round Electric Welded Steel Tubing
