Our Advantages

Advanced Anti-Corrosion Coating

The hubs are treated with a high-quality, multi-layer anti-rust coating. This superior surface finish provides exceptional resistance to moisture, chemicals, and harsh weather conditions, significantly extending the product's lifespan and maintaining a like-new appearance even after years of service.

Premium HT250 Material

Manufactured from high-grade HT250 cast iron, our hubs offer an excellent balance of strength, wear resistance, and heat dissipation. This material ensures remarkable structural integrity under heavy loads and high-stress conditions, guaranteeing reliable performance and a longer service life.

High-Strength Forging Process

Utilizing advanced forging technology, the grain structure of the metal is refined and aligned, resulting in superior tensile strength and impact resistance compared to conventional casting. This process creates a hub that is significantly stronger and more durable, capable of bearing maximum load capacities without compromising safety.

Packing & Delivery

Our trailer hubs are packaged in custom reinforced wooden crates, designed to withstand harsh handling and long-distance transportation. Each layer is fully wrapped with protective material (foam) to prevent scratches, corrosion, and impact damage.
