Key Technical Specifications

International Standards & Compliance for Drainage Steel Grating Trench Cover

To ensure the safety and reliability of urban infrastructure, we engineer and manufacture our drainage steel grating drain trench covers in strict accordance with global industry standards. We provide certified solutions tailored to the specific regulatory requirements of different regions:

European & Middle Eastern Markets (EN Standards)

• EN 124 / EN 1433: Our products meet the load-bearing classifications from A15 to F900, ensuring durability from pedestrian walkways to heavy-duty airport taxiways.

• CE Marking: All municipal products carry the CE mark, confirming compliance with EU safety, health, and environmental protection requirements.

• ISO 1461: Hot-dip galvanization strictly follows these standards to ensure maximum corrosion resistance in humid or saline coastal environments.

• SASO Compliance: We provide necessary documentation and testing for projects in Saudi Arabia and the broader GCC region.

North & South American Markets (ASTM/NAAMM/AASHTO)

• NAAMM MBG 531: Manufactured according to the Metal Bar Grating Manual for consistent structural integrity.

• ASTM A36 & A123: We use high-grade carbon steel with galvanization that meets North American industrial coatings standards.

• AASHTO M306: For highway and traffic applications, our gratings are tested to withstand H-20 and HS-25 heavy vehicular loads.

Australian & New Zealand Markets (AS/NZS Standards)

• AS 3996: Fully compliant with Australian standards for access drain covers and grates, ranging from Class A to Class G.

• AS 4586 (Slip Resistance): We offer specialized serrated surfaces tested to meet high Slip Resistance Ratings (P5/R11), essential for public safety in Australian municipal projects.

• NATA Accredited Testing: Load test reports from NATA-certified laboratories are available upon request for project verification.

Optimized Solutions for Urban Infrastructure Drainage Steel Grating Trench Cover

Our drainage steel grating drain trench covers are specifically designed to meet the rigorous demands of municipal environments. From bustling city sidewalks to heavy-duty public roadways, we provide infrastructure solutions that prioritize public safety and long-term durability.

1. Public Walkways & Pedestrian Plazas (Pedestrian Safety)

In high-traffic urban areas, safety is paramount. Our heel-proof (narrow gap) grating prevents high heels and walking canes from getting stuck, making it ideal for:

• City squares and pedestrian malls.
• Public park drainage systems.
• Subway and railway station entrances.

Key Feature: Anti-slip serrated surfaces to prevent accidents in rainy or snowy weather.

2. Municipal Roadways & Bus Stations (Heavy Load Capacity)

For areas subject to vehicular traffic, our gratings are manufactured to meet EN124 / ASTM load standards. We provide heavy-duty covers capable of withstanding constant pressure from buses, fire trucks, and maintenance vehicles.

• Street gutter drainage.
• Bus rapid transit (BRT) lane drainage.
• Public parking lot catch basins.

Key Feature: High-strength pressure-locked welding to prevent structural deformation under heavy loads.

3. Urban Water Management & Sustainable Cities (Sponge City Initiatives)

Supporting the “Sponge City” concept, our gratings offer a high open-area ratio (up to 80%) to ensure rapid rainwater infiltration, reducing urban flooding risks.

• Stormwater management systems.
• Landscape irrigation drainage.
• Eco-park water recycling channels.

Key Feature: Hot-dip galvanization (ISO 1461) ensures maximum corrosion resistance against road salts and urban pollutants.

4. Utility & Service Trenches (Ease of Maintenance)

Designed for easy access to underground cables and pipes, our municipal covers allow for quick inspection by city maintenance crews.

• Electrical and telecommunication cable trenches.
• District heating pipe covers.

Key Feature: Light-weight yet high-strength designs, often equipped with hinged or locking mechanisms to prevent theft and unauthorized access.

Why Choose Our Drainage Steel Grating?

1. 1. 1. 1. 1. 1. 1. Anti-Slip & Safe: Our serrated bar options ensure maximum safety in wet or oily environments.

                  2. High Drainage Efficiency: Optimized open-area design allows for rapid water runoff, preventing flooding.

                  3. Longevity: Hot-dip galvanization provides a protective layer that lasts 20+ years in most environments.

                  4. Cost-Effective Bulk Production: Our automated production lines allow us to offer lower prices for large-scale projects.
