Industrial Straightening & Leveling Solution: ISO 9001, +40% Flatness Accuracy

Straightening & Leveling

We provide access to industrial leveling services that correct internal stresses, edge wave, camber, and coil set in flat-rolled steel—delivering geometrically stable material that won’t distort during your downstream welding or machining. This solves a common frustration for international buyers: receiving hot-rolled or coiled steel that warps during fabrication. We work with processors who handle hot-rolled (Q355B, S355J2), abrasion-resistant (AR400), quenched & tempered (A514), and stainless grades, ensuring your raw material performs as expected.

Product Overview

Our vetted partners use multi-roll precision levelers capable of processing 1.0 mm to 100 mm thick plates and typically achieve flatness better than 2 mm per meter—meeting ASTM A568 Class II or EN 10029 standards. They adjust roll pressure based on material yield strength to avoid surface marking, and many offer optional flatness verification reports upon request. All maintain equipment calibration logs, giving you confidence that leveling isn’t just cosmetic—it’s engineered for fabrication stability.
