Polished steel square bar

Polished steel square bar

Polished steel square bar (also known as Polished Square Bar) is a solid square steel processed through cold drawing. Compared to standard black square bars, it possesses a smoother, cleaner surface texture and superior dimensional tolerances.
Due to its good structural strength and ease of processing, it is widely used in machinery part manufacturing, architectural decoration design, and various hardware processing, serving as a practical base material for industrial and engineering applications.

➤ Specifications
▪️ Size: 6.4mm～ 50.8mm
▪️ Material: SS400, S45C
▪️ Cutting Service: Standard lengths or custom precision cutting based on drawings.

➤ Product Features
▪️ High Dimensional Accuracy: The cold drawing process ensures precise cross-sectional dimensions (tight tolerances), suitable for slides or guides requiring precise assembly.
▪️ Smooth & Clean Surface: Removes the black oxide scale (mill scale) from the hot-rolling process, presenting the original bright metallic luster with excellent texture.
▪️ Enhanced Mechanical Properties: Through work hardening, its tensile strength and hardness are superior to hot-rolled steel of the same grade.
▪️ Cost-Saving Processing: Since the surface and size already meet high standards, allowances and time for subsequent turning, milling, or polishing are reduced.

➤ Applications
▪️ Precision Machinery Parts: Used for making keyways, sliders, guide rails, precision shafts, and other components.
▪️ Architecture & Decoration: Applied in forged railings, interior design grilles, and furniture frames to present a refined metallic texture.
▪️ Hardware & Tool Manufacturing: Suitable for producing hand tools, screw molds, jigs, and fixtures.
▪️ Automotive Parts: Used for manufacturing high-strength fasteners, connecting rods, and steering mechanism parts.
