20 years passed by, we made many quality tests on our Invisible Hinges, such as Fire rating(CG001 90 minites), Weight loading(CG001, 120 kgs/3 pcs), Salt spray test(Stainless steel 304 18 hours). and we pasted all of them with perfect performance.

We have more than 10 QC workers specially, and each product will be checked carefully before packing to avoid any inferior product shipped to our customers.

We have been producing Door Hardware Fittings(Invisible Hinges, Handles, Stoppers, Bolts) for more than 20 years, and we are pride of that the feedback rate of quality problem is less than 1%.
