Grills are made from different materials like stainless steel, mild steel, brass and cast Iron. Usually grills are either cylindrical rods or rectangular bars. Grills made from rectangular bars are much stronger compared to cylindrical. Also the bars could be hollow which is less strong then the solid bars/rods. Grills can be custom made too. We inspect quality control after the preparation of raw materials and after the production process which involves bolting and welding.
