Zhigu's custom forged wheels represent the pinnacle of engineering, starting with 6061-T6 aluminum billets forged under 15,000 tons of pressure to create a grain structure 50% denser than cast alternatives. Customization includes: 1) Multi-spoke or mesh designs with 2-12mm thickness; 2) Concave depths up to 4.5"; 3) Custom offsets from -50 to +80mm; 4) Surface treatments like Teflon-infused powder coat for 30% better debris shedding. Each wheel undergoes ultrasonic testing for internal flaws and is stress-relieved through thermal cycling. The result is a wheel 30% stronger and 25% lighter than cast equivalents, certified to ISO 9001 and TS 16949 standards.
