18 Gauge Steel Sheet Metal Panels | Cold Rolled 8x12 Inch (8-Pack)
Premium USA-Sourced ASTM A1008 Carbon Steel • Processed by The Metal Box Company
Product Overview
This listing features a premium, high-volume 8-pack of pre-cut 18-gauge cold-rolled steel sheet metal blanks. Each individual piece measures exactly 8 inches wide by 12 inches long, delivering a massive combined total of 672 square inches (4.67 square feet) of clean, workable material per package. Sourced directly from full-scale 4x10 foot commercial mill master stock, these panels are systematically processed down to highly requested retail profiles at our facility in Fort Smith, Arkansas. This structured workflow mirrors a traditional butcher portioning large bulk cuts down to individual consumer sizes—safeguarding material integrity, eliminating commercial bulk minimums, and delivering project-ready metal straight to your bench with zero waste.
Material & Technical Specifications Material Grade Heavy-Duty ASTM A1008 Commercial Grade Carbon Steel (Mill Finish / Black Iron) Thickness / Gauge 18 Gauge (Approximately 0.0478" / 1.21 mm) for structural stiffness and high weldability Dimensions (Per Sheet) 8 x 12 Inches (Exact Metric: 203.2 mm x 304.8 mm) Total Quantity 8 Heavy-Duty Sheets Per Pack (672 Square Inches Total Coverage) Processing Method Cold-Rolled for enhanced tensile strength, precise thickness tolerances, and superior flatness Magnetic Properties Magnetic (Standard, ceramic, or heavy-duty neodymium magnets adhere firmly) Country of Origin United States (Sourced domestically and processed in Arkansas) Condition & Edge Quality
- Surface Condition: Brand new, premium raw steel stock. The cold-rolling process ensures a smooth, uniform surface that provides an exceptional foundation for painting, priming, powder coating, or plating. The material features complete freedom from thick mill scale, drastically cutting down preparation time. A light film of rust-preventative oil is maintained to preserve the raw surface during transit.
- Edge Quality: Every plate is mechanically squared and shear-cut to precise commercial tolerances. Because these sheets are never plasma or laser cut, they possess zero slag, hardened edge crust, or thermal dross. This safely protects your drill bits, band saws, and tools from encountering premature brittle failure points.
Need Custom Dimensions? We Cut to Order at No Extra Cost
If your project requires specific smaller sub-sections or localized dimensions cut down from these 8x12 panel profiles, simply finalize your purchase and immediately send a message detailing your requirements. We will custom-shear the plates exactly to your layout specs before packing your order.
Ideal Applications & Uses
