PRODUCT QUALITY
Quality is controllable by our strictly test. We have many times test pre-production, mid- production and late production. Before pre-production, we will strictly select the raw material supplier to make sure our doors quality. In the mid-production, there are 3 production line. Every production line will be inspect by our professional QC. If there is any problem about the door in any production line, it will be repaired by our worker.
