ERW
ERW Mechanical Tubing
ERW mechanical tubing is produced by cold-forming steel sheets into a cylindrical profile. High-frequency electric current is applied to the edges, heating the material until they are fused together under pressure. This process creates a high-strength bond without the use of added filler metals, resulting in a clean, consistent weld.
Standard Specifications & Grades
We stock ERW mechanical tubing in both hot-rolled and cold-rolled finishes:
ASTM A513 Type 1: Hot Rolled (standard structural and mechanical use)
ASTM A513 Type 2: Cold Rolled (for tighter tolerances and superior surface finish)
Available Profiles & Sizes:
Round: 0.375″ – 16″ OD | 0.035″ – 0.250″ Wall
Square: 0.500″ – 6″ OD | 0.049″ – 0.120″ Wall
Rectangle: 0.500″ – 8″ OD | 0.049″ – 0.120″ Wall
