Turned Ground and Polished Steel Bar TGP Round Bar
Features
Turned Ground and Polished Steel bar is a silver bright steel produced by processing hot-rolled steel through processes such as annealing, cold drawing, and polishing. It has the characteristics of high dimensional accuracy and good surface quality. Especially for polished materials, which effectively remove surface decarburization layers, surface cracks, and various external defects. They are widely used in industries such as mechanical equipment manufacturing, electronics, petroleum, chemical, automotive, railway, shipbuilding, aerospace, nuclear power, etc.
Our company has a production capacity of 20000 tons/year, advanced production technology, excellent product quality, and products with high precision, high straightness, and high roundness.
Product varieties: high-quality carbon structural steel, alloy structural steel, bearing steel, spring steel, easy cutting steel, etc.
