Parking Lot Storm Drain Grates

Parking entrances and commercial plaza drainage areas mainly serve passenger vehicles. Although these vehicles have lower axle loads than trucks, they frequently accelerate, turn, and brake in limited spaces. These actions create repeated lateral forces on drainage grates.

Standard grates may loosen or shift under continuous side pressure. Our Dingjian parking lot storm drain grates are designed to withstand these parking traffic conditions. The item number is 400600. The outer dimensions are 480 × 700 mm. The load capacity reaches 120 kN and meets the B125 standard. The product provides stable performance under long-term passenger vehicle traffic.

The slot structure of these parking lot storm drain grates is designed to protect vehicle tires and improve driving safety. Vehicles often change direction in parking areas, causing tires to contact drainage grates from different angles.

If slots are too wide or edges are too sharp, tires may be damaged or wheels may become trapped. We use smoother bar designs with rounded edges to reduce these risks. The optimized slot width allows vehicles to pass over the grate smoothly during entry, exit, and turning operations. This design helps improve safety for both vehicles and drivers.

Parking areas have unique environmental conditions. Oil leakage, rainwater, and repeated tire contact can gradually affect the grate surface. Standard coatings may lose protection after long-term use.

We apply a durable coating system to these parking lot storm drain grates. The oil-resistant paint formula provides strong adhesion to the metal surface and improves resistance against wear and environmental exposure. The 480 × 700 mm size also provides a wider drainage opening area, helping remove standing water more efficiently and improving overall drainage performance.
