Galvanized Steel Grating for Car Parking is a specialized grating system engineered for automotive parking facilities with a focus on both functionality and durability. Its heavy-duty construction, using high-quality steel with a high tensile strength, accommodates daily vehicle traffic, including cars, SUVs, and light trucks, while promoting drainage and ventilation—critical factors for preventing water damage to vehicles and reducing condensation in enclosed structures, which can lead to mold and mildew. The galvanized finish, applied using a hot-dip process that ensures full coverage, including hard-to-reach areas, ensures longevity in both covered parking garages and exposed outdoor parking environments, withstanding the elements and vehicle fluids.
Parameter | Details |
Material | High-strength steel (Q355ND) with good low-temperature toughness, suitable for cold climates |
Length | 4m - 10m (customizable to fit the length of parking spaces and ramps) |
Width | 2m - 3m to accommodate standard parking space widths, including those for larger vehicles |
Thickness of bearing bar | 10mm - 20mm to handle the weight of various vehicles |
Galvanized layer thickness | ≥95μm (with chromate conversion coating to further enhance corrosion resistance) |
Load capacity | ≥5000kg/m² (tested for 20-ton vehicle static load to ensure it can bear heavy vehicles) |
Designed to withstand point loads from vehicle tires (up to 3.5 tons per axle) with minimal deflection (<2mm under standard car weight of 1.5-2 tons). The 30mm bar spacing is carefully calculated to prevent tire trapping, which can damage tires and the grating, while still supporting small vehicles like motorcycles with narrow tires. The load engineering also takes into account the impact of vehicles parking and maneuvering, ensuring the grating remains stable.
40% open area with a 5° slope design, which is optimal for water flow, accelerates water runoff, reducing standing water by 90% compared to solid concrete floors. This minimizes ice formation in winter, which can make parking lots slippery and dangerous, and prevents brake fluid, oil, and other vehicle fluids from pooling, which can cause slip hazards and damage to the parking surface. The drainage system also helps to keep the parking area clean and dry.
The galvanized coating requires no repainting or sealing, reducing maintenance costs by 60% over a 10-year period compared to painted steel alternatives. The durable construction also reduces the need for frequent replacement, further lowering lifecycle costs. Additionally, the grating's long service life of 20+ years ensures a good return on investment for parking facility owners.
It is widely used in outdoor parking lots (shopping center parking lots with hundreds of vehicles daily, stadium parking areas used during events), indoor parking garages (office building parking garages with daily employee and visitor parking, residential complex parking structures for residents' cars), and multi-story parking structures (airport parking garages with high vehicle turnover, hospital parking facilities with constant traffic). The grating serves as parking surfaces that provide a stable and safe area for vehicles to park, ramp flooring (with anti-slip enhancements such as serrated surfaces) that ensures vehicles can safely ascend and descend, and safety barriers between parking levels that prevent falls and provide a clear demarcation, enhancing both functionality and safety of the parking facility.
Customization includes variable panel sizes to fit column spacing in parking structures, ensuring a seamless fit and maximizing parking space. Anti-slip grating for ramps with 3mm serrations provides additional traction, especially in wet conditions. Color-coded options for designated parking zones (handicapped parking with blue coloring, electric vehicle charging stations with green coloring) help to organize the parking facility and improve wayfinding. We provide structural calculations for seismic zones to ensure the grating can withstand earthquakes and high-wind areas to prevent damage from strong winds, ensuring the safety and reliability of the parking facility.
