Hot Rolled Round Tubes
Hot Rolled Round Tubes
Hot Rolled Round Tubes are manufactured from flat-rolled steel that is formed into a tubular shape and welded using the Electric Resistance Welding (ERW) process. This method preserves material properties and creates a uniform structure without irregularities. Available in a wide range of diameters with relatively thin walls, these tubes are ideal for structural and mechanical applications requiring strength and lightness.
- A513 / A519
- Carbon Steel
- ERW Process
- Excellent Weldability
Overview
Hot Rolled Round Tubes are essential structural components manufactured from flat-rolled basic oxygen steel. The production process involves forming the steel into a precise tubular shape, followed by welding using the electric resistance method. This advanced welding technique ensures no loss of material properties and creates a uniform structure without irregularities, making these tubes reliable for demanding applications. Available in a comprehensive range of diameters, Hot Rolled Round Tubes are specifically designed with relatively thin walls, offering an excellent balance of strength and weight. For tubing measuring 1-1/4" OD and larger, internal flash is meticulously controlled to a maximum height of .010 inches, while smaller diameters typically contain flash. These tubes serve as fundamental building blocks for various projects requiring robust metal supply in Los Angeles, from structural frameworks to fencing systems. Their versatility makes them suitable for construction professionals, metal fabricators, and industrial contractors throughout the Los Angeles area who need reliable materials for structural tubing applications and mechanical projects. When you need consistent quality and reliable performance for your construction metal needs in Los Angeles, Hot Rolled Round Tubes provide the structural integrity and dimensional stability required for successful project completion across commercial, industrial, and infrastructure applications.

How to Measure & Specify
To specify a Round Tube:
- Outside Diameter (O.D.): Specify the tube's outer diameter in inches (e.g., 2.0").
- Wall Thickness (WT): Specify in inches or gauge (e.g., 0.125" or 11 ga).
- Length: Required length in feet (e.g., 20').
- Grade: Specify standard (e.g., ASTM A513).
- Full Spec Example: "2.0" OD x 0.125" wall x 20' length, ASTM A513"
Measurement Tip: Measure across the outside of the tube to get the O.D. Wall thickness is measured at any point around the circumference.
Order Checklist
