4 Pcs 20 Gauge Steel Sheets
These 12″ by 6″ cold-rolled steel plates come in a 4-piece set. Each sheet is 20-gauge (0.9 mm) and coated with a light protective oil to resist oxidation during shipping, then wiped clean before use. Made from low carbon steel, they offer strength, durability, and ductility with solid weldability. They’re designed to cut, drill, weld, and bend while preserving structural integrity, enabling clean, professional finishes for auto body repairs, brackets, or fabrications.
5 Pack 20 Gauge Sheet Metal
This set includes five 6″ x 12″ sheets of 20-gauge cold-rolled steel, offering a compact, versatile solution for DIY fabrications, auto repairs, and industrial projects. The material provides excellent durability and a smooth, uniform surface ideal for precision cutting and forming. It is highly weldable and formable, suitable for custom fabrications, prototypes, repairs, and a broad range of creative endeavors, with reliable performance across common welding methods.
2 Pcs 18 Gauge Steel Plates
Two 12″ x 9″ sheets of 18-gauge cold-rolled steel provide robust material for heavier-duty projects. Coated with a light protective oil to prevent oxidation during shipping, these sheets wipe clean before use. The steel offers strong, ductile properties with good plasticity, weldability, and resistance to shock and vibration, making them suitable for automotive structural components, brackets, and repair panels. They support cutting, drilling, welding, and bending while maintaining uniform, professional finishes.
4 Pcs 18 Gauge 16×12 Sheets
This set includes four 16″ x 12″ sheets at 18-gauge (1.2 mm). Each sheet is cold-rolled steel with a light protective oil coating for shipment, easily wiped clean, and ready for immediate processing. The material provides strong structural integrity, excellent weldability, and ductility for automotive fabrication tasks, including chassis work, brackets, and panel patches. The sheets are well-suited for cutting, bending, and shaping to achieve precise, durable results.
K&S Precision Stainless Sheet, 6×12
This 0.018″ thick stainless steel sheet (0.46 mm) is ideal for DIY automotive, crafts, and furniture applications. Made from 430 stainless steel, it offers excellent wear resistance, strength, and durability for demanding environments such as engine compartments, backplates, or decorative panels. It is commonly used across automotive, aerospace, and food-related applications where reliable structural performance and corrosion resistance are important. The sheet provides a balance of formability and toughness, suitable for various fabrication methods.
Buying Guide: Key Considerations For Automotive Sheet Metal Panels
- Material type and thickness: Choose steel grades (mild steel vs. stainless) based on corrosion resistance, weldability, and load requirements. Gauge thickness affects bending, cutting, and weight; higher gauges are thinner and more ductile, while lower gauges are stronger but harder to form.
- Dimensional needs: Match sheet size to the project footprint to minimize waste. Larger panels may be easier for large patches; smaller sheets are better for brackets and intricate shapes.
- Weldability and forming: Ensure the material is compatible with your preferred welding methods (MIG, TIG) and forming tools. Some alloys form cleaner welds with less distortion.
- Finish and surface care: Protective coatings can prevent oxidation during shipping. Wipe surfaces before use to ensure clean welds and finishes.
- Versatility vs. specialization: If you need a common stock for various tasks, 18–20 gauge mild steel sheets offer broad utility. Stainless steel sheets resist corrosion in exposed areas but may require specialized tools.
- Brand and sourcing: Reputable brands and reliable vendors help ensure consistent thickness, flatness, and surface quality. Check reviews for consistency in sheet flatness and edge quality.
- Cost vs. performance: Balancing material cost with project requirements is essential. For prototypes or hobbyist work, mid-range gauges often provide the best value with adequate formability.
- Safety and handling: Wear protective gear when cutting or grinding. Stainless steel can produce more heat during welding, so proper ventilation and coolants are advisable.
