Custom UHMWPE slide blocks and wear pads for dam gates. Direct from manufacturer. Self-lubricating, abrasion-resistant, and zero water absorption. Get your drawing machined to exact specs.

When it comes to the smooth and reliable operation of dam gates — including flood discharge gates, navigation locks, and tidal barriers — the slide blocks and wear pads play a critical role. Traditional metal sliders often suffer from corrosion, high friction, and the constant need for grease lubrication. More and more hydro projects worldwide are now switching to an advanced material: Ultra-High Molecular Weight Polyethylene (UHMWPE) sheet, machined into wear-resistant slide blocks.
As a manufacturer specializing in UHMWPE sheets and custom machining, we help engineering contractors and water management authorities replace problematic metal components with long-lasting, maintenance-free UHMWPE sliders.
Why Choose UHMWPE for Dam Gate Slide Blocks?
1. Exceptional Wear Resistance
UHMWPE offers abrasion resistance 7 to 10 times greater than standard steel. It holds its dimensions over time even under heavy gate cycles and silt-laden water flow, greatly extending the replacement interval of the slide system.
2. Self-Lubricating — No Grease Needed
The material has an inherently low coefficient of friction. Slide blocks made from UHMWPE allow the gate to move smoothly without the need for grease or lubricating oil. This means zero water contamination and much lower manual maintenance.
3. High Impact Strength, Zero Water Absorption
Dam environments can be harsh: floating debris, ice in winter, and high-velocity currents. UHMWPE absorbs impact without deforming or cracking. It is also completely impervious to water — no swelling, no expansion, no degradation.
4. Protects Rubber Seals
The naturally smooth surface of machined UHMWPE is gentle on the gate’s rubber sealing strips. It reduces seal wear significantly, helping maintain water-tightness and lowering the long-term cost of seal replacement.
Our Custom Machining Capabilities
As a factory-direct manufacturer of UHMWPE sheets, we don’t just supply raw material — we machine finished slide blocks and wear pads exactly to your specifications.
Fully Custom to Drawing: Send us your CAD drawing or a sample of your existing slider, and we will replicate it precisely. We handle cutting, drilling, countersinking, slotting, angle milling, and welding of UHMWPE components.
Wide Size Range: From small curved sliders only a few hundred millimeters to full-length side guide wear plates several meters long — all machined from a single piece, no joints needed.
Virgin UHMWPE Material Only: Every part is made from pure, high-molecular-weight virgin resin. No recycled filler. Mechanical properties meet or exceed international standards for hydraulic applications.
Tight Tolerances: Our CNC machining ensures a precise fit with embedded metal frames and track surfaces. Installation is straightforward and fast.
Proven in Field Applications
Our UHMWPE gate slide blocks have been successfully installed in reservoir spillways, river barrages, and coastal tide gates. They have solved recurring problems such as metal slider seizure, abnormal noise during operation, and frequent seal damage, earning strong feedback from maintenance teams and project owners.
