Shandong Rigang Supply Chain Management Co.,Ltd Zinc ingot refers to pure zinc, and of course there will be impurities, but as zinc ingot, it has at least 90% purity. The use of zinc ingots: mainly used in die-casting alloys, battery industry, printing and dyeing industry, pharmaceutical industry, rubber industry, chemical industry, etc. Alloys of zinc and other metals are widely used in electroplating, spraying and other industries. Zinc alloy die castings are used in automobile, light industry and other industries. The processing performance of many zinc alloys is relatively good, and the pass processing rate can reach 60%-80%. Excellent medium pressure performance, can be deep drawn, and has self-lubricating properties, which prolongs the life of the mold. It can be welded by brazing, resistance welding or arc welding (need to be in helium), and the surface can be electroplated and painted. Good cutting performance. It has superior superplastic properties under certain conditions.

Shandong Rigang stainless steel coil is made from hot-rolled steel coil as raw material, which is subjected to acid washing to remove oxide skin and then subjected to cold continuous rolling. The finished product is rolled hard coil. Due to the cold work hardening caused byStainless steel coil is a non-rusting metal product that is widely used in many fields due to its special properties in industrial production. The following is a brief introduction to the use of stainless steel coils in industrial production.

ShandongWelded steel pipe, also known as welded pipe, is a steel pipe made by welding steel plates or strips after being rolled and formed. Welded steel pipes are divided into straight seam welded pipes and spiral welded pipes according to the form of welds. Classified by production method: arc welded pipe, resistance welded pipe, (high-frequency, low-frequency) gas welded pipe, furnace welded pipe. The production process of straight seam welded pipe is simple, with high production efficiency, low cost, and rapid development. The strength of spiral welded pipes is generally higher than that of straight seam welded pipes. Narrow billets can be used to produce larger diameter welded pipes, and billets of the same width can also be used to produce welded pipes of different diameters. However, compared to straight seam pipes of the same length, the weld length increases by 30-100% and the production speed is lower. Thick wall coil products include: large coil, large diameter thick wall coil, various materials thick wall coil, hot rolled thick wall coil, cold rolled thick wall coil, etc.
All welded pipes can be made into galvanized welded pipes, which can be found through product consultation on the homepage.

Shandong Rigang  Hot-dip galvanized steel pipes are widely used in construction, machinery, coal mines, chemicals, electric power, railway vehicles, automobile industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery, greenhouse construction and other manufacturing industries..
