Dequn fixed-wheel steel gate is a welded sluice leaf with side rollers (fixed wheels) and a top lifting lug. Rollers reduce friction when the gate travels under high water pressure at reservoirs, hydropower outlets, and large canal structures.
Technical Specifications

| Working Head | High-head applications within engineered design |
| Seal Type | Rubber / composite / metal seals as specified |
| Coating | Shop primer + epoxy system; thickness per contract |
| Typical Applications | Reservoir outlets, hydropower works, large irrigation regulators |
| Quotation Mode | Custom fabrication from drawings |
Core selling points
- Lower operating friction: Rollers help the leaf move under high differential pressure.
- High-head capability: Welded stiffener grid supports large loads when properly designed.
- Custom span: Width and height follow project drawings—not limited to cast molds.
- Hoist compatible: Top lug connects to winch or electric hoist systems.
- Inspectable fabrication: Welds, rollers, and coating can be checked before shipment.
Who this product is for
Engineering buyers specifying steel gates for higher heads where plain sliding friction would demand excessive hoist capacity. Common on reservoir and hydropower-related outlets.
Design and manufacturing focus
The leaf is a welded steel panel with a stiffener grid on the back. Roller assemblies on both sides engage embedded rails. Wheel bearings and seals must be protected during transport and commissioning.
Compatibility and accessories
- Winch hoist or high-capacity electric hoist
- Embedded rails / guide shoes in civil concrete
- Spare rollers, bearings, and seal kits
- Coating touch-up materials for site repairs
FAQ
Q1: What is a fixed-wheel gate?
A: A steel sluice whose leaf uses side rollers to roll on rails, reducing friction versus plain sliding gates.
Q2: When should I choose rollers instead of a plane slide gate?
A: When design head or leaf weight makes sliding friction too high for the preferred hoist.
Q3: Do rollers need regular greasing?
A: Follow the project O&M plan. Bearings and seals should be inspected on schedule.
Q4: Can you manufacture to DIN or AWS welding requirements?
A: Welding and inspection scope can follow the contract standard when stated in the order.
Q5: What hoist capacity do I need?
A: Calculate from leaf weight, friction, seating force, and safety factor—share drawings for assistance.
Q6: Is this suitable for seawater?
A: Possible with stainless upgrades and a suitable coating system. Confirm chloride exposure in the RFQ.
Q7: How long is fabrication?
A: Lead time depends on size and inspection scope; confirmed after drawing approval.
Q8: What should the packing protect?
A: Rollers, machined seal faces, and coating edges during ocean transit.
