Long Description
We are a professional sheet metal & heavy steel structure fabrication manufacturer focusing on OEM custom precision large machine frames and equipment racks, providing one-stop processing services from design drawing optimization, blanking, welding, machining to surface finishing. Adopting standard qualified MIG welding technology, we ensure uniform, firm and aesthetic welding seams, perfectly meeting the assembly accuracy and load-bearing demands of large industrial machines, automation equipment, production line racks and mechanical supporting structures.
All products are manufactured using high-quality structural steel and sheet metal materials, paired with precise CNC cutting and fixed fixture assembly processes, effectively controlling product dimensional tolerance and overall verticality. We carry out full-process quality inspection, covering raw material screening, welding forming, precision calibration and finished product testing, to guarantee each machine frame runs stably under long-term operation, without deformation or loosening.
As a direct factory, we offer competitive wholesale prices without middlemen, support flexible OEM customization including size adjustment, structural modification, material selection and surface treatment customization. Whether for small-batch proofing or large-scale bulk orders, we guarantee stable delivery cycle, complete supporting documents and thoughtful after-sales technical support, becoming a reliable long-term partner for global equipment manufacturers.
