Qingdao Hexin specializes in manufacturing high-quality steel rollers such as forged steel rollers, grooved steel rollers, pressed steel rollers, roll assemblies, stainless steel rollers, and steel rollers for glass annealing. These rollers are made from materials like CK45 or CK40 seamless steel tubes or alloy steel, and undergo heat treatment (quenching and tempering), machining, welding, assembly, stress relief, surface hard chromium plating, super grinding, and abrasive finishing. With over 30 years of experience in roller production, our workshop ensures surface roughness as low as Ra 0.2, making them suitable for coating machines, printing machines, metallurgical equipment, membrane systems, paper processing equipment, textile machinery, and glue coating systems. Our rollers are also ideal for various film production lines, papermaking lines, and large-scale printing equipment.
