Steel tubing for OEMs and fabricators.

Square, rectangular, and round ERW tube that goes straight into your product — telescoping fits, flash-controlled IDs, dedimpled ends, and formable grades, from 18 ga to 1/4″ wall, mill-direct from Mansfield, Ohio.

What We Run for OEMs

Component tube, not commodity tube.

OEM tube has a job to do after it leaves the mill — it gets punched, formed, welded, telescoped, or coated. Our fabrication customers spec formability grades, fit-up tolerances, and end conditions, and we hold them run after run: support hardware, carrier racks, wall jacks, dock ladders, telescoping supports, and engineered building components.

Specs: ASTM A513 mechanical for parts, A500 for structural members (to 1/4″ wall, 2″×6″), and A1076 UV-coated precoated rounds for certified building components. Not sure which? Start with the A500 vs A513 comparison.

FAQ

OEM tubing, answered.

What tubing do OEMs and fabricators buy from Major Metals?

Square, rectangular, and round ERW tube from 18 ga up through 1/4″ wall, in hot rolled, HRPO, and galvanized — to ASTM A513 for mechanical parts, A500 for structural members, and A1076 UV-coated precoated tube for building components like truss webbing. Typical end uses on our spec sheets: support hardware, wall jacks, carrier racks, dock ladders, and telescoping assemblies.

Can you hold telescoping-fit tolerances?

Yes — we run tube specified to telescope into or over a mating tube, with ID/OD controlled to the fit. Tell us both members of the assembly and we'll tool to the clearance.

How tight can you control weld flash?

Flash-controlled ID down to .010″–.020″ per customer spec, plus dedimpled ends — both are standard requests from our OEM accounts, held to the spec sheet on every run.

Do you support formability and grade requirements?

Yes — chemistry-controlled grades for forming operations, higher-strength grades on request, and certified A1076 structural grades (e.g., Grade 42/65 rounds) for engineered building components. Certs ship with the material.
