Trustworthy quality, reliability and working closely with partner and customers around the world are the key reasons why we are one of the most competitive manufacturers in the market.
Our company has established brand image in the industry since 30 years ago, with rich experience and expertise in this field. We imported advanced technology from South Korea in March, 2000, ensuring our know-how leading position in the industry. At the beginning, we regard "rubber joint" as our core product. There are four product lines, including rubber joints & metal expansion joints, SS expansion bellows, rubber back valves and shock absorbers. We are expanding our business scope and focusing on water supply industry.
Quality is a part of our culture. We take it seriously on inspection and quality check, so we comply with ISO9001:2008 system. Actually, we are raising the bar on quality inspection. A unique independent quality inspection team was organized to handle the quality management system regularly before delivery. More new advanced technologies were used in the production and composition, saving more power and being better for the earth. Whenever and whatever you need the products, we will be your responsible partner after you inform us!
