    How We Pack Stainless Steel Coil

    For stainless steel coils, we wrap the coils in brown paper and bundle them onto wooden pallets. If extra protection is needed, we offer reinforced packaging with metal straps at the four corners, which may involve an extra cost. We also provide custom packaging options to suit individual customer needs, ensuring safe and tailored delivery.
