How We Hold Quality
A slip-resistant pattern mold area is located inside our factory. Workers control the pattern depth, pattern spacing, and grate thickness during production. These controls help maintain the slip-resistant surface and consistent product strength. Workers also check the pattern, size, and holes 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 during the inspection process. 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 and can be used to support project approval.
