Introducing our latest innovation in steel rims, embracing three remarkable types: welded, bolt seat, and flange-each meticulously crafted to offer distinct advantages tailored for diverse needs.
Welded Steel Rims: A Harmonious Blend of Strength, Beauty, and Longevity
Our welded steel rims undergo a rigorous, multi-stage grinding process using cutting-edge equipment coupled with expert manual finishing to create a flawlessly smooth surface. Crafted to endure the rugged terrains of agriculture and forestry, these rims boast superior stability, expertly absorbing high-intensity impacts and friction without faltering.
Bolt Seat Steel Rims: Versatility Meets Resilience for Unmatched Adaptability
Designed with ingenuity, the bolt seat steel rims connect seamlessly with the spoke through bolts, allowing flexible offset adjustments. This versatility empowers users to adjust bolt positions to suit specific needs, optimizing performance and efficiency of agricultural and forestry machines across varying complex environments.
Flange Steel Rims: Resilient and Ready for the Toughest Challenges
With a robust connection between rim and spoke via the flange, these rims form an unyielding structure capable of handling immense torques and impacts. Whether navigating muddy, rugged terrains or enduring frequent starts, stops, and turns, flange steel rims promise steadfast stability, resisting deformation and damage even in the harshest conditions.

To cater to varied customer requirements, we offer three distinctive packaging solutions:
- Pallet Packaging: Our standard method involves the use of fumigated pallets. Products are securely placed and expertly bound, ensuring stability throughout transportation.
- Carton Packaging: Using premium, size-customized cartons, we provide comprehensive protection for our products. Customers preferring this option should inform our sales team, noting the additional material and labor costs, which will be reflected in the packaging fees.
- Carton + Pallet Packaging: This dual approach combines the protective efficacy of cartons with the logistical ease of pallets. Products are packed in cartons and then stabilized on pallets, offering extra protection during transport. As with carton packaging, prior coordination with sales is needed, with additional fees applying for the carton part.
