Core selling points
- Large-span capability: Welded steel adapts to wide openings that are costly to cast.
- Reinforced frame: Gusseted side rails improve stiffness under load.
- Flexible operation: Works with screw, electric, or winch hoists.
- Coating options: Paint systems can follow tropical humidity and immersion needs.
- Drawing-based manufacture: Non-standard sizes are normal for this product line.
Who this product is for
Project teams comparing cast iron vs steel: choose this plane steel gate when opening size, head, or non-standard geometry exceeds economical cast-iron limits.
Design and manufacturing focus
Leaf plate thickness and stiffener layout are calculated from water head and span. The frame provides guided travel. Shop coating and seal grooves are completed before export packing.
Compatibility and accessories
- Gate hoist (manual-electric, electric, or winch)
- Embedded frame parts and anchor bolts
- Spare seals and fasteners
- Optional upstream trash rack
FAQ
Q1: Plane steel gate vs cast iron gate—how to choose?
A: Cast iron suits many small-to-medium openings. Plane steel is preferred for larger spans, higher heads, or custom panel shapes.
Q2: Can deflection be limited?
A: Yes. Stiffener depth and plate thickness are designed to meet the project deflection criteria.
Q3: Which steel grade is used?
A: Commonly Q235B or higher grades such as Q355B when specified. Confirm on the material certificate.
Q4: Do you follow SL 74 or AWS D1.1?
A: Manufacturing and welding inspection can follow the standards named in the contract.
Q5: What coating DFT should I specify?
A: Write the paint system and dry-film thickness into the PO; ISO 12944 categories are commonly referenced.
Q6: Is radial gate included in this product?
A: This page covers plane (flat) sluice gates. Radial gates are quoted separately from drawings.
Q7: What packing is used?
A: Steel frames or ISPM 15 wood supports with edge protection for coated panels.
Q8: How to start a quotation?
A: Send opening size, head, seal type, hoist type, coating requirement, and destination country.
