Our chain factory started 30 years ago making low grade steel chain for marine and decoration purpose, while accumulating experience, personnel & technology about chain material, chain welding, chain heat-treatment & chain application in various industries. Chain grades were covering Grade 30, Grade 43 and up to Grade 70. This was primarily due to then Chinese steel mill capacity insufficiency for developing higher strength alloy steel, but with carbon steel only for chain making industry.
Our chain making machines then were manual, and heat-treatment technology was still catching up.
Nonetheless, our determination and passion for round steel link chain making has helped us with practical achievements during those years:
When touring our chain factory today, it’s a modernized workshop equipped with latest full auto robotized chain making machine, advanced quenching & tempering heat-treatment furnaces, auto chain length tension test machines, complete sets of chain link & material testing facilities.
Thanks to China machinery engineering development, as well as Chinese steel mills R&D for high alloy steel materials (MnNiCrMo), we have well established our products range for now and future, i.e., quality and high strength round steel link chains for:
Our 30 years history of round steel link chain manufacture is not yet far from the beginning, and we have much to learn, to make and to create……we view our road for future an endless chain strand with each link to be of aspiration and challenge, and we’re determined to take it and walk it up:
