Overview
Matte Steel Bar combines austenitic 304 chemistry with a low-reflectivity matte surface for reliable corrosion resistance and a refined decorative appearance under varied lighting. The matte finish reduces glare and fingerprint visibility while maintaining consistent dimensional accuracy, making the bar suited to architectural handrails, display fixtures, kitchen equipment and modern interior systems. Supplied to ASTM A276 / EN 10059 with mill test certification per EN 10204 3.1, it supports global procurement for design-led architectural and industrial projects.

FAQ
Most enquiries reduce to a small set of recurring technical questions.
01 What is matte stainless bar?
Matte stainless bar has a non-reflective, low-glare surface typically produced by chemical etching or light abrasive brushing.
02 What are typical applications?
Matte bar is widely used for architectural and decorative hardware, indoor railings and kitchen / bathroom fixtures where reduced glare is preferred.
03 Is matte bar magnetic?
304 / 316 are austenitic and non-magnetic in the annealed condition. 430 is ferritic and magnetic.
04 What shapes are available?
Round, square, flat and rectangular. Common bar diameters 10 - 100 mm.
05 How is matte bar protected for shipment?
Individual PE sleeve and end caps protect the surface. Wooden crate or steel frame packaging for export.
