CKVIHAV Anodized Aluminum Sheet

CKVIHAV’s anodized aluminum sheet is crafted from 5052 aluminum alloy, delivering thickness that resists bending and deformation. The 12” x 16” sheet at 1/32” (0.80 mm) thickness provides a balance between rigidity and weight, suitable for laser engraving, signage, or decorative panels on race vehicles. The surface treatment reduces porosity and cracks, enabling precise engraving and consistent finishes. This sheet’s smooth, oxidation-treated surface is compatible with laser cutting and sublimation for custom branding and lightweight paneling on race cars.
ZOFORTY 6 Pack Aluminum Sheet 12 x 12

This set includes six 12” x 12” aluminum sheets at 0.02” (0.5 mm) thickness, made from 5052 aluminum alloy. They offer corrosion resistance and good welding performance, with flat, smooth surfaces suitable for precision cutting and shaping. The corrosion resistance makes them a practical option for lightweight body panels or interior components that benefit from non-magnetic properties and easy machining for race car builds.
Metoro 16-Gauge Mild CRS Steel Sheet

The Metoro sheet is a 16-gauge (approximately 1.5 mm) mild cold-rolled steel sheet, offering strong formability and magnetic properties. Its smooth surface finish supports aesthetic panel work and high-precision fabrication. It suits components that require stiffness and structural integrity in delimited areas of a race car, such as brackets, gussets, or reinforcing plates. The sheet’s magnetic nature and good weldability support typical metalworking workflows in automotive projects.
Eastwood 20-Gauge Aluminized Sheet Metal Kit

The Eastwood aluminized sheet metal kit comprises seven pieces of 20-gauge aluminized steel in various sizes (12” x 24”, 12” x 12”, and 1” x 24”). The aluminized coating provides corrosion resistance, increasing longevity in automotive environments where moisture and road salt may be present. The kit is designed for welding, forming, and patching car panels, with a balance of thickness that allows productive fabrication without excessive weight addition.
Zonon 8 Pcs Steel Sheet Metal Pack

Each Zonon sheet measures 12” x 6” with a thickness of 0.032” (0.8 mm) in Q195 cold-rolled carbon steel. The pack provides multiple sheets that can be directly cut, formed, and welded, making it a flexible option for patchwork, brackets, or small structural components. The cold-rolled finish supports clean cuts and consistent drilling, suitable for rapid prototyping or finalizing components in a race car build.
Yaocom 2 Pcs 16 x 12 Inch Mild Steel Sheet

Yaocom offers two pieces of 16” x 12” mild steel sheets at 0.06 inches (1.5 mm) thick. The sheets are weldable and suitable for heavy-duty fabrications, brackets, and reinforcements in automotive projects. The material’s ductility and good weldability make it a reliable choice for structural components that require endurance under stress and vibration inherent to race environments.
Alffun 2 Pcs 16 Gauge Sheet Metal

Alffun provides two 16-gauge (1.5 mm) cold-rolled steel plates, each 12” x 8”. The sheets are coated with a light protective oil to prevent oxidation during shipping and are easy to wipe clean before use. They offer good plasticity, weldability, and resistance to shock and vibration, enabling precise cuts, drilling, and forming for automotive hardware, bracing, and mounting brackets in racing builds.
Buying Guide: Key Purchase Considerations
- Material properties: Aluminum alloys (e.g., 5052) offer light weight and good corrosion resistance, ideal for panels and decorative elements. Steel provides higher strength and stiffness for brackets and structural components but is heavier and may require coatings for corrosion resistance.
- Thickness and gauge: Thinner sheets reduce weight but may deform under load; thicker sheets add rigidity but increase weight. Align thickness with the expected mechanical stress and forming operations.
- Welding and fabrication: Steel is generally easier to weld with common methods; aluminum requires specific welding techniques and may demand skilled fabrication. Plan for compatible fasteners and joinery methods accordingly.
- Surface treatment: Anodized and aluminized finishes improve corrosion resistance and longevity in automotive environments. Consider coatings if the sheet will be exposed to road debris, salt, and moisture.
- Machinability: For racing components that require precision cuts or laser engraving, ensure the material supports the intended process without cracking or excessive burrs.
- Cost and availability: Aluminum and steel prices vary by alloy and thickness. Availability from suppliers can influence lead times for race car builds.
- Application fit: Use lightweight aluminum for exterior panels or interior trim, and high-strength steel for brackets, mounts, and load-bearing parts. Always assess particle weight distribution and center of gravity implications for performance.
- Corrosion resistance: Aluminized steel and aluminum alloys resist corrosion, beneficial for under-vehicle components exposed to moisture, salt, and heat. Coatings can extend service life in harsh environments.
- Welding and tools required: Ensure your shop has the right tools for welding, cutting, and forming the chosen metal. Some alloys require specific wire, shielding gases, and heat input settings to avoid warping.
- Repairability: Consider ease of repair or replacement during maintenance and after-track incidents. Readiness to source spare sheets can save downtime between events.
Selecting the right sheet metal for a race car project involves balancing weight, strength, fabrication ease, and resistance to the demanding track environment. The options listed here provide a spectrum from lightweight aluminum for panels to robust steel for structural components, enabling targeted choices based on design goals and workshop capabilities.
