Surface & Edge Processing
Surface finish: 2B matte / 2B bright
Surface roughness：Ra 0.05–0.09μm
Edge : Slit edge
Burr height: 10% of material thickness
Anti-rust treatment: Uniform thin anti-rust oil coating on surface
Coil Parameters
Precision stainless steel cold-rolled strips are wound on plastic reels with an inner diameter of 280 mm (11.024 inches). The maximum outer diameter of the steel strip reel is 870 mm (34.252 inches). This means that a single strip with a width of 22.1-22.4 mm (0.870-0.882 inches) can have a maximum weight of approximately 91-93 kg.
(Note: Delivery sizes and special dimension requirements can be customized as per request.)
