Our production facilities feature three production lines for stainless steel coiled tubes and pipes. We have more than ten years of exporting experience and are equipped with bending, stretching, saw cutting, stamping, polishing, and other processing equipment. Our stainless steel products are widely used in bathroom fittings, hangers, hardware, condensation heating equipment, and hotel supplies. We welcome domestic and foreign customers to provide drawings or samples.
We have experience exporting stainless steel tube products for more than ten years.
Our production of stainless steel coils has a history of ten years, featuring two production lines that produce continuous welded pipe using advanced technology. We have introduced bright annealing technology, allowing online softening treatment of stainless steel pipe. In addition, we conduct compression testing, flaring, bending, 100% hardness tests, tensile strength testing, and air tightness testing. Prices are reasonable and quality is reliable, with 80% of our coils currently exported worldwide.
Seamless coiled tubing is the preferred choice in critical applications, as it eliminates the risk of impurities often associated with welded coiled tubing.
