We proudly present our trio of superior steel rims: the welded type, bolt seat type, and flange type, each boasting distinct, unparalleled advantages tailored to elevate performance.
Welded Steel Rims: A Harmonious Blend of Strength, Elegance, and Endurance
Post-welding, each rim undergoes meticulous and multi-tier grinding with state-of-the-art equipment and skilled hand-finish to banish burrs, offering a pristine, sleek surface. Engineered for the toughest agricultural and forestry environments, these welded steel rims excel in withstanding high-impact forces and friction, ensuring outstanding stability and resilience.
Bolt Seat Steel Rims: Ingenious Flexibility and Unmatched Versatility
Exquisitely crafted, the bolt seat steel rims connect with the spokes via bolts, allowing for effortless offset adjustments. This adaptability is the cornerstone of their design, enabling users to precisely calibrate bolt positions to tailor the wheel offset for diverse agricultural and forestry scenarios, thereby enhancing operational efficiency across various challenging terrains.
Flange Steel Rims: Unyielding Stability, Robustness, and Harsh Environment Mastery
Through a secure flange connection, the rim and spoke unite into a formidable structure with exceptional bonding strength, capable of enduring substantial torques and impact forces. In demanding settings like farmland and forested areas, where uneven, muddy terrains and frequent maneuvering are prevalent, flange steel rims maintain unwavering stability without deforming or succumbing to damage.

Catering to diverse customer needs, we offer three versatile packaging options to ensure your products reach you safely and efficiently:
- Pallet Packaging: Our standard method employs durable fumigated pallets. Products are securely placed and expertly bound, ensuring unwavering stability throughout transit.
- Carton Packaging: Utilizing premium-quality, custom-sized cartons, we provide comprehensive protection for your products. Please notify our sales team should you require this option, as it incurs additional material and labor charges.
- Carton + Pallet Packaging: This dual approach merges the protective prowess of cartons with the logistical ease of pallets. Products are first ensconced in cartons before being anchored on pallets, delivering double-layered protection during intricate shipping processes. Kindly liaise with our sales team for this packaging choice, as supplemental fees apply for the carton component.
