Introducing our latest innovation in steel rims with three distinct types: welded, bolt seat, and flange. Each type offers unique advantages tailored to meet your agricultural machinery needs.
Welded Steel Rims: Engineered for Strength, Style, and Longevity
Our welded steel rims are masterfully crafted, undergoing an extensive grinding process using advanced equipment and meticulous manual refinement. This ensures a seamless, burr-free finish that not only looks great but also performs exceptionally well in rugged agricultural settings. These rims are built to endure intense impacts and friction, delivering optimal stability in demanding environments.
Bolt Seat Steel Rims: Adaptability and Precision at Your Fingertips
Designed with innovation in mind, the bolt seat steel rims offer a unique connection between rim and spoke through robust bolts. The standout feature is the adjustable offset, allowing users to tailor bolt positions for optimal performance in diverse conditions. This flexibility enhances machinery adaptability, boosting operational efficiency in complex agricultural and forestry tasks.
Flange Steel Rims: Resilience and Reliability in Extreme Conditions
Featuring a solid flange connection, these rims boast a formidable structure that can withstand immense torque and impact. Perfect for challenging terrains like muddy fields and dense forests, they maintain stability during frequent operations such as starting, stopping, and turning, ensuring durability and deformation resistance.

Nestled in the Quanlin Innovation and Entrepreneurship Park, our company has been at the forefront since 2018 in R&D, production, and sales of commercial vehicles, tractors, harvesters, and premium aluminum alloy wheels. Our accolades include being recognized as a national high-tech enterprise and a distinguished technology-based SME, along with Shandong's "specialized, refined, unique, and new" enterprise title.
With an impressive production capacity, we manufacture 1 million agricultural and forestry wheels, 800,000 commercial vehicle wheels, and 100,000 forged aluminum alloy wheels annually. Our commitment to quality is evidenced by our IATF16949 and US DOT certifications. We've also forged strong partnerships with industry giants like Dongfeng Motor Corporation, SINOTRUK, AGCO, and CLAAS Shandong.



To cater to diverse customer requirements, we offer three versatile packaging options:
- Pallet Packaging: Our default choice employs fumigated pallets, ensuring secure placement with professional bundling techniques, guaranteeing stability throughout transit.
- Carton Packaging: Tailored high-quality cartons provide comprehensive protection, customized for product size. Please notify our sales team if this is your preferred option, as it incurs additional costs due to extra materials and labor.
- Carton + Pallet Packaging: This dual approach merges the superior protection of cartons with the practicality of pallets. Products are encased in cartons first, then secured on pallets, offering enhanced protection in challenging shipping conditions. For this method, please coordinate with our sales team to discuss the additional carton costs.
