Aluminium Rectangular Box Assembly with Modular Welded Frame Module and Diagonal Cross-Bracing

Outer frame dimensions, diagonal brace angles, and bolt-hole pattern positions are the three governing callouts for this modular welded frame module; all controlled to your print tolerances using welding fixtures and post-weld dimensional inspection at Meiyu's Changsha facility. Aluminium section stock is cut to length and welded with cross-bracing clamped in position before tack welding to prevent angular distortion. ISO 3834 welding quality management and ISO 9001 certification govern each weld procedure qualification, inspector qualification, and dimensional record at Meiyu's Hunan plant (north of 35,000 m²). EN 15085 certification is held for welded rail and structural applications. The facility serves automation, construction, rail transit, and new energy storage customers with fabricated aluminium frame assemblies. Clients include automotive, military, and railway buyers. Provide section size, brace configuration, and weld quality class and your drawing for quoting. For a direct quotation.
