Custom race panels demand rapid bending, stamping, and cutting, but standard painted metals often suffer from paint flaking, micro-cracking, and corrosion along fold lines.
Paint damage during fabrication leads to high scrap rates, costly touch-ups, and delayed race prep timelines.
High-formability, factory-coated aluminum coils designed specifically to withstand harsh forming processes without compromising coating integrity.
Achieves 0T–2T bend capability without coating micro-fractures, seam peeling, or loss of adhesion.
Ensures sharp-edge forming and intricate contouring for custom race car aerodynamic panels.
3003-H14 / 3105-H14/H24: Excellent ductility and smooth surface finishing for easy roll-forming and hand-shaping.
5052-H32: Superior tensile strength and impact resistance for high-stress zones (rocker panels, wheel arches, chassis skirts).
Pre-applied high-tack protective film (PE film) prevents scratches and scuffs during shearing, punch pressing, and shop handling.
Lower Scrap Rates & Higher Yield: Eliminate re-painting and touch-ups, directly reducing raw material waste and labor costs.
Time-to-Track Efficiency: Ready-to-bend prepainted coils allow fabricators to go directly from cutting table to vehicle installation.
Vibrant & Consistent Aesthetics: High-gloss, UV-resistant finishes (PE/PVDF/HDP) available in exact Pantone/RAL codes to match race team and sponsor branding.
