How We Hold Quality
A lock structure assembly area is located inside our factory. Workers fit the lock catch and check its position and opening. The lock structure helps reduce the risk of theft while keeping the grate easy to open manually. Workers also check the holes, color, and size of each batch. Buyers can install the grate after delivery.
We run three levels of quality control: incoming material spot checks, process patrol checks, and finished goods factory checks. Quality checks are performed on a fixed schedule. We spot-check products and raw materials. Third-party inspection is welcome. A full inspection is not performed before packing; spot checks are carried out before packing. Quality is monitored throughout the process. Material documentation and inspection data are available to buyers. This data can help with project approval.
