What materials do you use? How do you ensure strength and durability?

We use 7075/6061 aluminum alloy, alloy steel, carbon steel, stainless steel 304/316, and insulated composite materials depending on product type. Each product features clear breaking strength ratings and WLL (Working Load Limit). Strength is guaranteed through CNC precision machining, batch tensile testing, heat treatment, surface hardening, and corrosion-resistant coatings to achieve long-term durability for industrial use.
