As a professional manufacturer based in Hengshui, Hebei, China, Hengshui Ruibin New Materials LLC specializes in producing high-performance drainage solutions. Our 304 Stainless Steel Trench Drain Cover with Load Class C250 and anti-slip surface is engineered for heavy-duty drainage applications where reliability and safety are paramount. Backed by a 1,000-3,000 square meter factory and a skilled team of 101-200 employees, we deliver precision-crafted products that meet international standards and are exported to major markets worldwide.
This trench drain cover is designed to withstand demanding environments such as roadways, parking lots, industrial zones, and pedestrian areas requiring robust load-bearing capacity. The C250 classification ensures it can handle static loads up to 25 tons, making it suitable for vehicles and heavy machinery. The anti-slip surface pattern provides excellent traction, reducing the risk of accidents even in wet or oily conditions. Crafted from premium 304 stainless steel, this cover offers superior corrosion resistance, longevity, and a sleek appearance that maintains its finish for years.
Our manufacturing process adheres to strict quality control measures, ensuring each cover meets the specified dimensions (1000mm × 100mm) with tight tolerances. The slot design optimizes water flow while preventing debris clogging. We also offer customization options for size, load class, and surface pattern to fit specific project requirements. Whether you need a simple replacement or a large-scale drainage system, our team provides technical support and efficient logistics from Port of Tianjin or Port of Qingdao.

Frequently Asked Questions (FAQ)
- Q: What does load class C250 mean? A: C250 is a European standard (EN 1433) meaning the cover can withstand a static load of 250 kN (25 tons). It is suitable for areas with heavy vehicle traffic, such as roads and parking lots, but not for airfield runways (which require D400).
- Q: Is the cover truly anti-slip? A: Yes, we use a diamond or checker plate surface pattern that provides a slip resistance rating of R9–R10, tested according to DIN 51130. This makes it safe even when wet or greasy.
- Q: Can I order custom sizes or load classes? A: Absolutely. We customize dimensions, load classes (A15, B125, C250, D400), and surface patterns based on your requirements. Minimum order quantity may apply for custom sizes.
- Q: What is the typical lead time? A: For standard 1000×100mm C250 covers, lead time is 7–15 days after order confirmation. Custom orders may take 15–25 days, depending on complexity. Express delivery available.
- Q: Will 304 stainless steel rust in coastal areas? A: 304 stainless steel has good corrosion resistance but may develop surface discoloration in extreme marine environments. For coastal or chemical exposure, we recommend our 316L stainless steel option (available upon request).
- Q: How is the cover installed? A: The cover can be installed directly into a pre-cast concrete trench or fitted with our optional stainless steel frame. We provide installation instructions and can recommend suitable sealants.
- Q: What is the drainage capacity? A: The slotted design allows a flow rate of approximately 70–80 liters per second per meter length, depending on the slot width and gradient. This meets typical heavy rain runoff requirements.
- Q: Do you offer samples? A: Yes, we provide small samples for evaluation. The sample cost is refundable with bulk orders. Please contact our sales team for details.
