Gated hardware ground springs are usually made of cast iron high strength stainless steel or other metallic materials, with excellent corrosion resistance, oxidation resistance and strength, and high reliability.

What are ground springs made of?

The basic configuration of the ground spring is the celestial axis and the earth axis (or foundation). The axle is a fitting that connects the door frame to the door fan at the top, consisting of a button-type shaft fixed to the door fan with adjustable bolts and a shaft sleeve fixed to the door fan. The shaft can be applied to almost all wooden, steel, aluminum alloy doors and rimless glass doors using glass clamps.
