Introducing our latest innovation in agricultural machinery components, we proudly present three distinct varieties of high-quality steel rims: the robust welded type, the adaptable bolt seat type, and the resilient flange type. Each offers unparalleled advantages tailored to meet diverse agricultural needs.
Welded Steel Rims: A Perfect Blend of Strength, Elegance, and Longevity
Crafted to perfection, our welded steel rims undergo meticulous post-welding processes, including extensive and multi-tier grinding with advanced machinery coupled with manual precision to eradicate burrs, ensuring an impeccably smooth finish. These rims triumph over intense impacts and friction, delivering exceptional stability in the challenging terrain of agricultural and forestry environments.
Bolt Seat Steel Rims: Versatile Solution with Superior Adaptability
Ingeniously crafted, our bolt seat steel rims feature a dynamic design that links the rim and spoke via bolts. This design marvel offers the significant advantage of flexible offset adjustments. Users can effortlessly reposition the bolts, modifying the rim's offset to meet specific operational conditions, thus enhancing the machinery's performance adaptability in diverse and challenging agricultural and forestry settings.
Flange Steel Rims: Unwavering Strength and Resilience in Adverse Conditions
Engineered for durability, our flange steel rims tightly connect the rim and spoke through a robust flange, creating an unyielding structure. They boast superior connection strength, capable of withstanding immense torques and impact forces. These rims excel in rugged environments like farmlands and forests, enduring muddy, uneven terrains, and frequent operational shifts without succumbing to deformation or damage.

To cater to our customers' diverse requirements, we offer three tailored packaging options to ensure optimal product protection:
- Pallet Packaging: Our default method, utilizing fumigated pallets, ensures products are securely placed and professionally bound to guarantee stable transport.
- Carton Packaging: Employing premium-quality cartons that are custom-fitted to product dimensions, this option provides comprehensive protective encasement. Please inform our sales team if you require this packaging, as it incurs additional material and labor costs.
- Carton + Pallet Packaging: This dual-layered approach merges the meticulous protection of cartons with the practical handling benefits of pallets. Products are enveloped in cartons before being stabilized on pallets, offering enhanced safeguarding in complex transit scenarios. Prior arrangement with our sales staff is necessary for this option, and additional fees apply for the carton component.
