Introducing our latest innovation: three exceptional types of steel rims-welded type, bolt seat type, and flange type-each crafted to offer unparalleled advantages and meet diverse needs.
Welded Steel Rims: Uncompromising Strength, Aesthetic Appeal, and Longevity
After precise welding, our welded steel rims are meticulously polished through a combination of advanced machinery and skilled manual techniques. This comprehensive refinement process ensures the elimination of burrs, delivering a flawlessly smooth surface. Designed for challenging agricultural and forestry environments, these rims boast remarkable resilience against high-impact forces and friction, providing exceptional stability and durability.
Bolt Seat Steel Rims: Remarkable Flexibility and Adaptability
Ingeniously constructed, the bolt seat steel rims feature an innovative design that connects the rim to the spoke using bolts. The key advantage lies in their adjustable offset, allowing users to effortlessly modify bolt positions to adapt to specific conditions. This flexibility enhances the performance of agricultural and forestry machinery, ensuring superior handling in diverse and challenging work environments, ultimately boosting operational efficiency.
Flange Steel Rims: Robust, Resilient, and Built for Extremes
Engineered for strength, the flange design securely links the rim and spoke, forming an exceptionally stable structure with high connection strength. These rims are built to endure immense torques and impact forces. In demanding terrains such as farms and forests, where mud, rugged landscapes, and constant movement are the norm, flange steel rims maintain their form and functionality, resisting deformation and damage with unwavering stability.
