Product Description

This service is intended for customers who need specific steel members or joint forms welded by a qualified fabrication team. ZSJH reviews material grade, thickness, joint design, welding position, access, distortion control and inspection requirements before production. The workflow can include fit-up, tack welding, preheating where specified, controlled welding, cleaning, visual inspection, dimensional checks and reporting.
