Our quality control ranges from the selection of raw materials to cold forging of blanks, tooth rubbing, and full-scale inspection of optics. 2. In the whole manufacturing process, we will divide all dimensions and performance into semi-finished products, finished products and the final three stages. 3. It is widely used in bed frames, iron doors, folding chairs, garden equipment, fences, stairs, ships, docks, machine tools, DIY projects etc. 4.
