Introducing the 380x680 UL-ECVP Anti-Corrosion Drainage Grate, a high-performance SMC composite solution engineered for demanding road and infrastructure applications. Manufactured by Qingdao Elite New Materials Co., Ltd., a leading specialist in SMC drainage products since 2019, this grate combines advanced material science with rigorous quality standards to deliver exceptional durability, safety, and sustainability. Designed to outperform traditional metal grates in corrosive and high-traffic environments, it is the ideal choice for commercial and industrial clients seeking long-term, cost-effective drainage solutions.
Our composite drainage grate features an innovative triple protection mechanism that sets it apart from conventional galvanized steel alternatives. The glass fiber reinforcement layer creates a robust anti-corrosion barrier, resisting acids and alkalis with a pH range of 1-13. The mineral substrate provides superior ultraviolet stability, meeting the ASTM G154 5000-hour standard to prevent photoaging. The resin matrix further blocks oxidative penetration, ensuring consistent performance even in harsh conditions. This design extends the maintenance-free period to 5 years, compared to 2-3 annual coating maintenance cycles for metal grates, making it perfect for coastal high-salt spray environments such as port terminals and industrial corrosion zones like chemical plants.
Committed to environmental responsibility, we operate a closed-loop production system where 40% of raw materials are recycled plastics and industrial by-products, certified by the Global Recycled Standard (GRS). Our manufacturing process reduces energy consumption by 55% compared to metal grate production. At the end of its service life, the 380x680 grate is 100% recyclable and has passed UL ECVP environmental verification. Overall, it delivers an 82% reduction in carbon footprint compared to galvanized steel grates, helping commercial purchasers meet their ESG goals.
Safety is our top priority, which is why we use nano-imprinting technology to create a multi-level surface microstructure. Macroscopic rhombus anti-skid lines (15mm spacing, 2mm depth) are combined with microscopic silica sand particles (particle size 0.2-0mm) to achieve a dry friction coefficient μ ≥ 0.85 and a wet friction coefficient μ ≥ 0.65, exceeding the DIN 51130 R12 standard. A special formula adds silicon carbide wear-resistant particles, ensuring the grate retains 80% of its original anti-skid performance after 200,000 standard wear tests.
While initial investment may be comparable to metal grates, the 380x680 composite grate delivers substantial long-term savings. Its resistance to rust, corrosion, and UV degradation eliminates frequent repainting and repairs, cutting whole-life maintenance costs by 67%. The modular design also simplifies installation, reducing labor costs for infrastructure projects.

The 380x680 UL-ECVP Anti-Corrosion Drainage Grate has been successfully deployed in high-profile projects worldwide. At the Bahrain F1 Circuit, it withstood 240km/h tire impacts, with its excellent shock absorption surprising engineering teams. In Shenzhen's Sponge City Pilot project, the grate improved drainage efficiency by 45% during heavy rainstorms, while its modular design reduced installation time by 30%. It is also widely used in data center campuses, urban roads, park facilities, and industrial zones.
We understand that every project has unique requirements. In addition to our standard 380x680 specification, we offer customized solutions for different sizes, load ratings, and surface finishes. Our products are exported to over 7 countries including the United States, Australia, Germany, the United Kingdom, India, and South Africa, and we provide dedicated support from initial consultation to after-sales service.
The 380x680 SMC composite drainage grate has a Medium Duty load rating, making it suitable for most urban road, parking lot, and pedestrian area applications. We also offer grates with higher load ratings for heavy traffic areas.
Yes, it is specifically designed for harsh corrosive environments. Its triple anti-corrosion mechanism resists high salt spray, making it ideal for coastal ports, marinas, and beachfront properties.
The 380x680 grate has a 5-year maintenance-free period, compared to 2-3 annual maintenance cycles for traditional galvanized steel grates. This reduces whole-life maintenance costs by 67%.
