Our C250 composite non-conductive drainage grate represents the next generation of urban infrastructure solutions, engineered to address the critical limitations of traditional metal grates. Manufactured from premium SMC (Sheet Molding Compound) materials, this 400×400mm model delivers exceptional strength, safety, and durability while maintaining a lightweight design. Ideal for roadways, sidewalks, electrical substations, industrial facilities, and public parks, it meets both domestic and international quality standards, including ASTM E2837 load requirements.
Unlike cast iron or steel alternatives, our composite drainage grates eliminate common issues such as theft, corrosion, and electrical conductivity, making them a cost-effective and low-maintenance choice for long-term infrastructure projects. With a proven track record in major global developments, our grates have been tested to withstand extreme weather conditions, chemical exposure, and heavy vehicular traffic.
Despite weighing only 22.0 kg – significantly lighter than equivalent metal grates – our C250-rated drainage grate is engineered to support heavy vehicle traffic without compromising structural integrity. The advanced composite material distribution ensures uniform load distribution, preventing cracking or deformation even under repeated stress. This combination of light weight and high strength simplifies installation, reduces labor costs, and minimizes workplace injuries during handling.
Composite materials are inherently electrically non-conductive, making this grate the safest choice for areas with electrical hazards. It eliminates the risk of electric shock in locations near power lines, electrical substations, data centers, and industrial facilities where metal grates pose a significant safety threat. This feature has made our product the preferred solution for electrical utility companies and infrastructure managers worldwide.
Our SMC drainage grates withstand pH1 to pH14 chemical environments, making them impervious to rust, acid rain, saltwater, and industrial chemicals. Unlike metal grates that require regular painting and replacement, our composite grates maintain their structural integrity and appearance for decades, reducing lifecycle costs by up to 70%. This makes them ideal for coastal areas, chemical plants, and food processing facilities.
We understand that every infrastructure project has unique requirements. Our composite drainage grates can be molded into a variety of shapes, sizes, and colors to match specific design specifications. We offer full customization of dimensions, load ratings, surface patterns, and branding elements. Our engineering team works directly with project stakeholders to develop tailored solutions that meet exact project timelines and performance criteria.

Our commitment to innovation and quality excellence drives us to use state-of-the-art production equipment and cutting-edge manufacturing technology. Every drainage grate undergoes rigorous quality inspection to ensure compliance with international standards. We maintain full control over the production process, from raw material sourcing to final testing, guaranteeing consistent product quality and performance.
We provide a comprehensive one-stop service that covers every stage of your project: from initial product design and custom manufacturing to quality inspection, logistics distribution, and after-sales support. This integrated approach eliminates the need to coordinate with multiple vendors, significantly reducing communication costs and project delays.
Our composite drainage grates are trusted by leading infrastructure developers and industrial partners worldwide. They have been successfully deployed in major projects including Mexico City Airport, Stockholm brewing facilities, and Bangalore vertical farming operations.
"Meets ASTM E2837 load standards – handles typhoon rains with 2× faster drainage than metal grates!" — Carlos Mendez, Mexico City Airport Engineer
"Withstands PH1-PH14 corrosion – no more brittle grates in malt acid environments!" — Emma Johansson, Director of Brewing in Stockholm, Sweden
We are committed to sustainable manufacturing practices and environmental stewardship. Our SMC/BMC materials are eco-friendly, and we have implemented processes to minimize carbon emissions throughout the product lifecycle. Additionally, we actively support educational projects and environmental initiatives, including community programs that benefit local workers and families.
This model has a C250 load rating, which means it can support up to 250 kN of test load, making it suitable for light to medium vehicular traffic in urban areas.
Yes, our composite drainage grates are 100% non-conductive, making them the safest choice for locations near electrical systems, substations, and industrial facilities where electric shock is a concern.
Absolutely. We offer full customization services, including custom dimensions, load ratings, surface patterns, colors, and branding. Our engineering team will work with you to develop a solution that meets your exact project requirements.
Our composite grates offer several advantages over metal grates: they are non-conductive, corrosion-resistant, theft-proof, lighter in weight, and require minimal maintenance. They also provide faster drainage and have a longer service life.
