Rubber Water Gate Seal Component

Our company specializes in manufacturing high-quality rubber fender blocks (rubber bumper pads) specifically designed for sluice gates, (gate leaves), lock gates, and other hydraulic structures. Made from a premium blend of natural and synthetic rubber through high-temperature vulcanization, these products offer excellent elasticity, abrasion resistance, impact absorption, and weather-ability – effectively protecting gate structures and concrete from damage while extending service life.

Key Features

Efficient Cushioning

Unique energy-absorbing design significantly reduces kinetic energy during gate opening/closing and water flow impact, minimizing rigid collisions.
Water & Weather Resistance

Formulated with anti-ozone, anti-UV, and hydrolysis-resistant additives for stable performance under long-term submersion or outdoor exposure.
Easy Installation

Pre-drilled bolt holes or embedded steel plate connections allow secure attachment to gate side seals, bottom sills, and gate leaves; simple replacement.
Customizable Dimensions

Length, width, curvature, and hardness (Shore A 50~80) can be tailored according to gate specifications and impact load requirements.
Sealing Compatibility

Smooth surface finish works in coordination with rubber water seals to enhance water-tightness.

Typical Applications

Side and bottom impact protection for vertical lift gates and radial gates
Cushioning for lock culverts, miter gates
Limit stop protection for dams, pumping stations, and weir gates
Retrofitting old gates and new hydraulic construction projects
