INDUSTRIES SERVED: Mining, Cement, Agriculture
As a professional China manufacturer and supplier of polyurethane wear liner sheets with expanded metal mesh backing, we are dedicated to providing industrial wear solutions that extend equipment life. Our liners are manufactured using high-grade prepolymers through a hot casting process, bonding the polyurethane securely to a robust expanded steel mesh. This unique structure combines the exceptional abrasion and impact resistance of polyurethane with the structural rigidity and installation versatility of steel. Unlike solid steel liners, our PU sheets offer noise reduction and are significantly lighter, making them easier to handle.
These wear liners are essential for industries dealing with abrasive bulk materials. They are widely utilized in mining and mineral processing, grain handling, concrete and aggregate plants, power generation, and cement production. Specifically, they are installed in transfer chutes, hoppers, bins, vibrating screens, and truck beds to prevent structural damage caused by sliding abrasion and impact from raw materials.

Case 1: The Aggregate Solution
A quarry client faced frequent downtime due to steel chute failure. We supplied 12mm steel expanded mesh backing polyurethane wear liner sheets. The weldable mesh allowed quick retrofitting. The result was a 300% increase in wear life, significantly boosting their ranking among local suppliers for efficiency.
Case 2: Grain Handling Efficiency
A grain terminal struggled with sliding abrasion in curved spouts. Our flexible mesh-backed liners contoured perfectly to the bends. The low friction PU surface improved flow rates, and the client was pleased with our responsive after-sales service regarding installation advice.

When selecting the right liner, consider these factors:
- Budget & Testing: Request a sample to verify the bond strength before committing to a full order.
- Identify Wear Type: Is it sliding abrasion (requires harder PU) or impact (requires softer, thicker PU)?
- Installation Method: Choose expanded mesh for welding or solid steel plate for bolting.
- Thickness Selection: Heavier material flow requires thicker liners (e.g., 20mm+) to maximize service life.
- Environmental Factors: Check if UV resistance or hydrolysis resistance is required for outdoor/wet use.
