Qingdao Hexin is a leading manufacturer specializing in high-quality steel rollers for various industrial applications. Our product range includes forged steel rollers, grooved steel rollers, pressed steel rollers, roll assemblies, stainless steel rollers, and steel rollers specifically designed for glass annealing. These rollers are manufactured using CK45 or CK40 seamless steel tubes or alloy steel as the raw material. After undergoing quenching and tempering heat treatment, machining, welding, assembly, stress relief heat treatment, surface hard chromium plating, super grinding, and super abrasion, our products meet the highest quality standards.
With over 30 years of experience in roller manufacturing, our workshop ensures a surface roughness of Ra 0.2, making our rollers suitable for coating machines, printing machines, metallurgical equipment, membrane systems, paper machinery, textile equipment, and glue coating devices. Our rollers are also compatible with various film production lines, papermaking lines, and large-scale printing equipment.
