Cold Drawn Bar
White shaft steel or Cold Drawn Bar It is steel that has been processed from... Round Bar By undergoing a cold-drawn process at normal temperatures, the steel is reduced in size to achieve superior properties compared to conventional hot-rolled steel, both in terms of surface finish and dimensional accuracy.
Our products are made from standard grade steel. SS400 This is the most popular grade on the market. The steel has consistent hardness, a clean surface, and is free of rust and black stains, making it ready for immediate use without extensive surface finishing.
Key features of AY Contento's bright steel shafts.
- Precision (High precision): It has very low dimensional tolerances, allowing it to fit into bearings or drilled holes better than black steel.
- Smooth Surface (Beautiful glossy surface): The smooth, glossy surface gives a premium feel, ideal for furniture or architectural projects where the material's texture needs to be showcased.
- Machinability (Ease of turning): The steel is ductile and hard enough, making it suitable for lathe work, milling, or threading.
- Straightness: Having been precisely straightened, it remains stable and does not wobble when rotated in machinery.
Applications
- Mechanical work: Used to make shafts, nuts, screws, and various fasteners.
- Furniture work: Chair legs, door handles, balustrades (for indoor use), and loft-style decor.
- Automotive work: Motorcycle parts, axle, bushings.
- Fence work: Italian wrought iron fences or gates that require a smoother, more elegant look than reinforcing iron bars.

Frequently Asked Questions (FAQ)
Round steel bars (e.g., SR24) The surface is rough, black, and the dimensions are inaccurate. Suitable for reinforced concrete work. White shaft steel The finish is smooth, the silver is shiny, and the size is much more precise, making it ideal for mechanical work and display purposes.
Yes, since it's carbon steel (not stainless steel), it can rust if exposed to moisture. We recommend applying a protective paint or rust-preventive oil if not in use immediately.
