Trench Grates & Frames

Trench grates cover the drainage channels, allowing water to enter while preventing debris and large objects from obstructing the flow. They come in various materials, including cast iron, ductile iron, galvanized steel, stainless steel, and aluminum. Each material offers distinct advantages:

Cast Iron: Known for durability and strength, suitable for heavy-duty applications.

Ductile Iron: Combines strength with ductility, making it resistant to cracking under heavy loads.

Galvanized Steel: Offers corrosion resistance and is often used in industrial settings.

Stainless Steel: Provides superior corrosion resistance, ideal for environments exposed to harsh chemicals or marine conditions.

Aluminum: Lightweight and resistant to corrosion, suitable for pedestrian areas.

Grates also vary in design, with options like parallel grates, perpendicular cross-street drainage, and ADA-compliant variations. They are available in various widths, typically ranging from 6 inches to 26 inches, to accommodate different drainage needs.

Excellent Drainage Performance
With an open area of up to 83.3%, it provides more than twice the drainage efficiency of traditional cast iron covers.

Hot-Dip Galvanized Finish
The trench grating features superior corrosion resistance—maintenance-free for up to 30 years, even in harsh environments.

Secure Hinged Design
Integrated hinge connection between cover and frame helps prevent theft, enhances safety, and allows for easy opening and closing.

Cost-Effective Investment
Offers better value than cast iron in heavy-load, long-span applications, and saves on replacement costs due to theft or breakage.

High Strength and Load Capacity
Significantly stronger and more impact-resistant than cast iron—suitable for ports, airports, and other heavy-duty environments.

Customizable Options
Available in various sizes and shapes to suit different environments, load requirements, spans, and installation needs.

Ordering Guidelines
Please select the appropriate model based on trench width and load capacity, or consult Hengchen's technical team for assistance.

Trench Grating is widely used in municipal roads, landscaping facilities, residential communities, schools, stadiums, ports, urban roads, squares, parks, docks, airports, parking lots, highways, railways, industrial projects, and various other civil and industrial buildings.
