G1 Green Tech is a company that specializes in door gasket.
We are producing the gaskets that can be applied to all kinds of doors such as sliding windows and doors, front door, automatic door and glass door etc.

A lot of energy is lost between the chinks in the door and external harmful material flows in. It is difficult for the general product to solve this problem due to the low function of durability, friction, lifespan and restoring force and the product limit.

As G1 Green Tech uses TPU material and solves the crucial function and the problems in gasket all the time, our products are recognized as the ones having consumers' conveniences and excellent function. G1 Green Tech always think over and endeavor to solve eco-friendliness and consumers' conveniences, together with its effort to think about the product from consumers perspectives and provide good products.
