Lengge runs its own manufacturing facility in Hebei province — China's core production region for steel and construction hardware. The entire process from raw material intake to finished packing happens in-house. No outsourcing, no subcontracting. When you place an order, it goes straight to our production floor, not to a third-party workshop.The factory covers over 20,000 square meters and is set up to handle both standard bulk runs and custom specification orders. What you see here is what makes your product.
Every beam is cut, pre-drilled, welded and hot-dip galvanized in-house, then quality-checked against our own inspection reports before it ships — giving buyers documented proof of strength and safety, not just a supplier's word.
