Product Introduction
Spec Sheet

Basic Description

This engineered drainage solution is designed for efficiency and aesthetics. The HDPE channel provides a lightweight,corrosion-proof,and easy-to-install base. It is paired with a durable metal slot grate,engineered with precise,narrow openings (slits) that effectively capture surface runoff while filtering out debris. The standout feature is the fully customizable slit configuration—choose the number (1-3) and placement (center or offset) to match specific hydraulic requirements and design visions,making it ideal for creating clean,minimal lines in modern paving.

Core Strengths

Customizable Drainage Precision:

Choose from 1,2,or 3 slits in center or side positions to optimize water intake for your project's specific flow rate and design layout,offering unparalleled design flexibility.

Durable Hybrid Construction:

Combines the chemical resistance and lightness of HDPE for the channel with the high load-bearing strength and longevity of stainless or galvanized steel for the grate.

Superior Debris Management & Flow:

Narrow slot openings allow rapid water entry while effectively blocking larger debris like leaves and stones,reducing maintenance and risk of blockage.

Architectural Aesthetics & Discreet Profile:

Creates clean,continuous lines in paved surfaces. The metal grate provides a sharp,professional finish that complements contemporary architectural designs.

Easy Installation & Modularity:

The lightweight HDPE channel simplifies trench work and handling. Modular sections allow for easy creation of long,straight runs or customized layouts.

Corrosion-Resistant & Long-Lasting:

The HDPE channel is impervious to rust and chemicals. Paired with a premium stainless or galvanized steel grate,the system ensures decades of reliable performance with minimal upkeep.

Application Scenario

Commercial & Public Spaces:

Building entrances,pedestrian plazas,shopping malls,and airport terminals where sleek aesthetics and efficient drainage are required.

Pool Decks & Patios:

Perimeter drainage with side slits to capture water runoff discreetly along edges.

Driveways & Parking Areas:

Linear drains with center slits to intercept water flow across surfaces.

Balconies & Roof Terraces:

Lightweight solution for effective water removal without overloading the structure.

Industrial & Food Processing Areas:

Where chemical resistance (HDPE) and easy cleaning (stainless steel) are critical.

Installation and Maintenance

Installation
  • Excavate a straight trench with the required fall (slope) for drainage.
  • Prepare a solid,level sub-base (e.g.,lean concrete) to support the channel.
  • Assemble and place the HDPE channel sections into the trench,ensuring they are level and aligned.
  • Surround the channel with concrete for lateral support,leaving the top opening clear.
  • Once the concrete sets,place the pre-selected metal slot grate into the channel's mounting frame.
  • Complete the final paving up to the edges of the grate.
Maintenance
  • Regularly sweep the grate surface to prevent debris from accumulating over the slots.
  • For thorough cleaning,the metal grate can be lifted out (if designed as removable) to clear any fine sediment from the HDPE channel beneath.
  • The HDPE channel can be flushed with water or a mild cleaning solution. The metal grate can be cleaned with appropriate methods (e.g.,mild detergent for stainless steel).
  • Inspect the grate and channel connection periodically to ensure stability.
