Hot-Dipped Galvanized Steel Grating: Key Advantages & Technical Specifications
Technical Specifications
Material
Q235 low-carbon steel: Delivers balanced mechanical properties at a cost-effective price point.
Stainless steel (304/316 grades): Offers superior corrosion resistance for specialized operating environments.
Dimensions (Load-Bearing Flat Bar × Cross Bar)
Load-bearing flat bars: Common sizes include 20×5, 25×5, 30×3, 30×5, 40×5, 50×5 mm.
Cross bars: Typical specifications are 5×5, 6×6, 8×8 mm.
Different combinations of these sizes can satisfy varying load-bearing demands.
Mesh Size
Mesh dimensions are customizable. Smaller meshes enhance safety and stability, while larger meshes prioritize ventilation and drainage efficiency at a lower cost.
Galvanized Coating Thickness
The hot-dip galvanization process ensures an average zinc coating thickness of ≥ 85μm, with a minimum local thickness of 70μm. These metrics comply with national standards, effectively bolstering corrosion resistance and extending product lifespan.
Load-Bearing Capacity
Load capacity varies by product specification. For instance, the 303/30/100 model supports a uniform load of 3.5kN/m² and a concentrated load of 3.85kN. Select the appropriate specification based on the actual load requirements of your application scenario.
Surface Treatment Options
Primary treatment: Hot-dip galvanization for a uniform, dense zinc coating and maximum corrosion protection.
Custom treatments: Cold galvanization or painting are available upon customer request.

Q: How long can the hot - dipped galvanized steel grating last?
A: In normal outdoor conditions, it can last over 20 years due to the thick anti - corrosion zinc layer. But lifespan may vary in special environments like chemical plants.
Q: What's the installation process like?
A: It's quite simple. First, align the grating accurately. Then, secure it using bolts or welding. Installation time is short, saving you both time and labor costs.
Q: How to maintain the hot - dipped galvanized steel grating?
A: Maintenance is easy. Just conduct occasional inspections. Since it has high corrosion resistance, there's no need for frequent upkeep. Only repair if any damage is found.

Core Advantages
-
Exceptional Corrosion ResistanceA dense zinc coating bonds to the steel surface via hot-dip galvanization, effectively shielding it from rust and corrosion. Boasting an outdoor service life of over 20 years, it is ideal for harsh environments like chemical plants and coastal regions.
-
Outstanding Strength & Load-Bearing CapacityManufactured with high-grade steel bars and optimized bar configurations, standard-grade grating can withstand 3–5 tons per square meter. It is perfectly suited for heavy-duty industrial zones and high-traffic areas.
-
Superior Slip ResistanceIts distinctive surface texture boosts friction significantly, with a slip resistance coefficient exceeding 0.6. This prevents accidental slips on wet or dusty walkways and stair treads.
-
Effortless Installation & Low MaintenancePre-fabricated for swift assembly, it can be fixed quickly with bolts or welding, cutting down on labor and installation time. Routine maintenance is minimal—only occasional inspections are needed, reducing long-term operational costs.
Top-Tier Quality & Full CustomizationOur factory implements strict quality control protocols, with every batch of steel grating undergoing rigorous testing to guarantee premium quality. Moreover, we offer tailor-made solutions, customizing size, shape, and load capacity to match diverse project requirements, regardless of scale.
Installation & Usage Guidelines
Pre-installation check: Verify the dimensions and quality of the grating before installation.
Installation: Align the grating precisely and secure it firmly using bolts or welding.
Load management: In high-load areas, strictly adhere to the rated load capacity to avoid overloading.
Regular inspection: Periodically check for signs of damage or corrosion to ensure safe, long-term operation.
