Hot Rolled Structural Steel Tubing

Structural steel tubing is manufactured from hot rolled shot blasted and oiled prime carbon flat rolled steel, which is cold-formed into a tubular shape and electric resistance welded. It is produced to the physical and chemical requirements of ASTM A500 B and structural steel tubing is readily fabricated. It may be bent, flared, flattened, swaged, punched, drawn and can be mechanically joined or welded by all the commonly used practices.

Mechanical sizes range in lengths from 20 to 24 ft.

Rectangular Mechanical Tube

Mechanical sizes range in lengths from 20 to 24 ft.

Round Mechanical Tube

Cold Drawn Seamless (CDSM): Round steel tubing that is available in a wide range of sizes. Good machinability, weldability and formability. ASTM A 519. This product is gradually being replaced by drawn over mandrel tubing.


Drawn Over Mandrel (DOM): Made by roll forming and welding steel strip. Welding flash removed on OD and ID. Tube is then normalized and drawn over a mandrel, producing a tube with excellent surface finish, closer tolerances than CDSM, and superior concentricity and straightness. Not used in pressure applications. ASTM A 513 Type 5.


Welded: Lowest cost steel tubing. Flash removed on OD. Used for rollers, spacers, conduit, etc. ASTM A513 Type 1 or Type 2.

Round Welded Tube

Seamless Hydraulic Tube

All of our hydraulic tubing is seamless, fully annealed, and pressure tested. They meet J.I.C. standards.
