Products Description
Produced by , this 11.25-21 three-piece split steel wheel rim consists of three independent parts: main rim body, outer bead ring and lock ring, specially developed for heavy-duty off-highway engineering, mining and port transportation equipment. Adopting thickened high-strength steel integrated rolling molding technology, the split three-piece design greatly simplifies tire disassembly, repair and replacement, effectively reducing equipment maintenance downtime.
All surfaces are treated with double-layer electrostatic anti-rust gray coating, with tight paint adhesion, resisting erosion from mine dust, muddy water and humid marine air. Precision CNC machining ensures uniform bolt hole distribution and accurate size tolerance. The 0mm offset design realizes even load dispersion, stable high-load operation and anti-impact & anti-deformation performance.

Core Advantages
Detachable three-piece design
Separable main rim, bead ring and lock ring structure, no large professional dismantling tools required. Tire replacement and daily inspection can be completed efficiently, cutting production loss caused by vehicle shutdown.
Made of high-strength, thick steel
Whole rim rolled from thick Q345 high-strength steel plate without weak splicing seams. Reinforced stress area can withstand frequent collision and heavy load on rocky mine roads, avoiding rim crack, deformation and tire detachment.
Full-coverage anti-rust coating
Inner and outer walls are fully sprayed with anti-rust primer and topcoat. The smooth gray paint film is scratch-resistant and anti-oxidation, extending service life under harsh working conditions such as mines and coastal ports.
Stable driving performance
6 evenly distributed mounting holes with strict dimensional accuracy, perfectly matched with heavy-duty vehicle axles. Zero offset balances wheel pressure evenly, eliminating shaking during full-load transportation.

FAQ
Q: What tires match this 3-piece engineering rim manufactured by Anyang Anqiang Steel Wheel Co.,Ltd.?
A: It fits all standard 11.25 width, 21-inch inner diameter OTR off-road tires, widely used for mine, port and construction engineering special tires.
Q: Is this wheel rim suitable for harsh mine working conditions?
A: Absolutely yes. Adopting thickened Q345 high-strength steel integral rolling molding and reinforced bead ring structure, it effectively resists heavy impact, extrusion and torsion from rocky and muddy mine roads, not easy to deform or crack.
Q: Can you customize the rim parameters according to customer requirements?
A: Yes. Anyang Anqiang Steel Wheel Co.,Ltd., Ltd. supports full personalized customization, including center hole, PCD, bolt hole diameter, offset, wall thickness, paint color and OEM logo printing.
Q: What is the anti-rust service life of the rim?
A: Adopting double-layer electrostatic spraying process (primer + topcoat), the anti-rust service life can reach more than 3 years in conventional outdoor working environments, and more than 2 years in humid coastal ports and underground mining environments.
Q: What is the advantage of 3-piece rim compared with integrated rim?
A: The three-piece split structure can be disassembled completely. It is extremely convenient for tire replacement, tire repair and rim maintenance. It can greatly reduce maintenance time and equipment downtime, which is more suitable for frequent maintenance of heavy-duty engineering vehicles.
Q: Do you provide factory inspection reports?
A: Yes. Each batch of products will undergo strict dimensional inspection, appearance inspection and hydraulic pressure load test. We can provide official factory quality inspection reports for customers.
