20' or 24' R/L
Description: ASTM A513 Type 1 is produced to O.D. and Wall dimensions. This is the least expensive mechanical tubing. It is produced from low carbon steel & possesses relatively good cold working characteristics. Also available as special order in DS, HSLA, galvanized, flash-controlled and telescoping.
Application: Used for furniture, storage racks, machine components, fences and more.

Description: ASTM A513 Type 2 is produced to O.D. and Wall dimensions. It is produced from low carbon steel & possesses relatively good cold working characteristics. Also available as special order in DS, HSLA, galvanized, flash-controlled and telescoping.
Application: Used in environments where cosmetically appealing surfaces and light weight are required. Examples include display racks, furniture, greenhouses, exercise equipment, and many others.

Chemistry
Tolerances
Round1/4" OD x .035" W
to
12" OD x 5/8" W

17'/24' RL
Description: DOM tubing is normally produced to O.D. and I.D. dimensions. It is an Electric Welded Tube, redrawn to remove weld flash, control dimension and improve properties. DOM stands for “drawn over mandrel” and the material is tested for weld soundness and straightness. This product is superior in finish and wall uniformity to seamless tubing. DOM offers superior dimensional tolerances, concentricity and mechanical properties.
Application: Commonly used in the automotive, appliance and construction industries.
Hot Finish Seamless1026 HRA519
Chemistry
Tolerances
Round3" OD x 1/2" W
to
20" OD x 3" W

17'/24' RL
Description: Hot Finished Tube is produced to O.D. and Wall dimensions. It is a lower-cost product than Cold Drawn Seamless tube and is a good material for applications that do not require the close dimensional tolerances and quality of surface finish that a Cold Drawn Seamless tube provides. If tight tolerances are required, machining is used to finish the product to exact specifications.
Application: Hot Finish Seamless tubing is used for products that require a thicker wall and a high strength material such as hydraulic cylinders, rollers and sleeves.
Cold Drawn Seamless
1026 A519
Chemistry
Tolerances
Round3/4" OD x .083" W
to
8" OD x 1" W

17'/24' RL
Description: Cold Drawn Seamless Tube is normally drawn to O.D. and I.D. dimensions. It has closer dimensional tolerances, better surface finish and higher mechanical properties than corresponding grades of Hot Finish Seamless tubing.
Application: Cold Drawn Seamless tubing is used for mechanical applications such as bushings, spacers, or other parts where mechanical properties are not specified or required.
