Zhigu's alloy wheels combine A356 cast and 6061-T6 forged aluminum solutions to meet diverse automotive needs. Cast wheels (15-20kg for a 20-inch rim) offer cost-effective styling for family cars, while forged wheels (7-15kg for a 20-inch rim) deliver high-strength lightweight performance for luxury and high-performance vehicles. Key capabilities include 15-26 inch sizes, monoblock/2-piece/3-piece constructions, customizable PCD/CB/offset, beadlock designs for off-road use, and international certifications (DOT, ISO, TUV/JWL/VIA). The factory's 5000-ton forging presses create dense molecular structures, ensuring wheels pass 1.5x JWL/VIA impact standards and endure 1 million cycle fatigue tests.
