Rectangular Support Frame Assembly with Stainless Steel Support Frame and Multiple Large Openings

Support frames with large rectangular openings concentrate weld distortion at the corners; without a controlled welding sequence and fixture, the frame warps and bolt-hole pattern shifts outside tolerance, requiring costly rework at installation. Meiyu's Changsha line uses sequenced, procedure-qualified welding under ISO 3834 certification to produce this stainless steel support frame with rectangular openings and bolt-hole pattern within your drawing tolerance. Post-weld dimensional inspection verifies frame squareness and hole positions before release. ISO 9001 and EN 15085 certifications govern structural welded member production at Meiyu's Hunan facility (north of 30,000 m²) serving construction machinery, rail transit, automotive, and industrial equipment customers. Output serves military, automation, and railway buyers. For pricing, provide bolt-hole pattern, frame squareness tolerance, and weld quality class — our Changsha fabrication team will confirm feasibility and price from your print.
