Product Introduction
Spec Sheet

Basic Description

Galvanized linear slot drain grate compliant with EN124 standards, crafted from carbon steel with hot-dip galvanized finish for superior corrosion resistance. Featuring linear slotted design with optional curved/straight profiles, it delivers high-efficiency drainage, anti-clog performance and flush installation, ideal for municipal roads, plazas and landscape projects.

Core Strengths

Customizable Slit Design for Targeted Drainage:

Offers unparalleled flexibility with a choice of 1,2,or 3 slits,positioned centrally or to the side. This allows for precise water capture tailored to the project's specific paving layout and runoff patterns.

Durable Hot-Dip Galvanized Protection:

The post-fabrication galvanizing process provides a thick,bonded zinc layer that protects against rust and corrosion,ensuring long-term durability in exterior and wet environments.

Enhanced Strength with Bottom Reinforcement:

Optional welded support ribs on the underside dramatically increase the grate's load-bearing capacity and resistance to deflection,providing peace of mind for heavier-duty applications.

Efficient Debris Management & High Flow:

The narrow slot openings allow rapid water intake while effectively filtering out larger debris like leaves and litter,reducing clogging and maintenance needs compared to wider-mesh grates.

Clean,Architectural Aesthetic:

Creates sharp,continuous lines in paved surfaces. The simple,linear design complements modern architectural styles,from commercial plazas to contemporary residential landscapes.

Proven Performance & Cost-Effectiveness:

Delivers the strength and durability of steel with excellent corrosion resistance at a more accessible price point than stainless steel,offering great long-term value.

Installation and Maintenance

Installation
  • This grate is designed to be installed into a compatible linear drainage channel (trench drain) system.
  • Ensure the supporting drainage channel is level and properly bedded.
  • Place the grate into the channel's receiver or onto its supporting ledger.
  • It may be secured with standard clips,bolts,or set in place depending on the system design.
Maintenance
  • Periodically sweep the slit openings to clear surface debris.
  • Rinse with water as needed. The galvanized surface is low-maintenance.
  • Inspect for any physical damage to the zinc coating in harsh environments; minor scratches are self-protected.
