Product Overview
This listing features pre-cut 18-gauge cold-rolled steel sheet metal blanks. Each individual piece measures exactly 8 inches wide by 12 inches long, delivering a clean 96-square-inch fabrication layout. Sourced directly from massive 4x10 foot commercial mill stock, these panels are systematically processed down to highly requested retail dimensions at our facility in Fort Smith, Arkansas. This method mirrors a traditional butcher portioning large cuts down to individual consumer sizes—eliminating bulk purchasing waste and delivering project-ready metal directly to your shop.

- Surface Condition: Brand new, premium raw metal stock. The cold-rolling process ensures a smooth, bright finish that provides an excellent base for painting, powder coating, or plating. The material features complete freedom from mill scale. A light film of rust-preventative oil may be applied to preserve the raw surface during transport.
- Edge Quality: Every plate is mechanically squared and sheer-cut to precise dimensions. Because these sheets are never plasma or laser cut, they possess zero slag, hardened edge crust, or dross. They arrive with smooth, parallel edges ready for immediate alignment, welding, or bending.
