We operate some foreign trade. The domestic construction has developed well in the past two years, and the demand for anti-theft doors and fire doors is increasing day by day. We have found Shuangpeng Industrial Co., Ltd. in China after many understandings and field visits. After a period of understanding and negotiation, we signed a long-term contract for security doors and villa doors. After two years of cooperation, we feel that we have really found the right partner. Their products are sold well in us, with high quality, and are welcomed by some middle and high income people. And they have good reputation, timely delivery, and good post-service.
