Products Description
Stainless Steel Serrated Grating is a strong and corrosion-resistant grating designed for demanding environments. Made from Stainless Steel , it performs well in areas exposed to moisture, chemicals, or salt air, such as coastal and industrial sites.
The serrated surface provides better traction under wet or oily conditions, helping reduce slip risks in everyday use. It's commonly used for walkways, platforms, and stairs, where both durability and safety are important.
Core Product Features
Superior Corrosion Resistance
The thickness of the hot-dip galvanized layer is ≥85μm with strong adhesion. It can be used in harsh outdoor environments such as humidity, acid and alkali for more than 20 years without rusting.
High Load-Bearing Capacity
Adopting grid or serrated structure design, the compressive load can reach multiple levels from C250 to F900, meeting the load-bearing requirements of different scenarios such as sidewalks, carriageways and heavy-duty lanes.
High Drainage Efficiency
The opening rate of the grating can reach 30% - 50%, allowing rainwater to infiltrate quickly and effectively reducing road ponding.
Easy Installation
Lighter than cast iron products, equipped with hooks, supports and other accessories, a single person can complete loading, unloading and maintenance.
High Cost-Effectiveness
The cost of steel raw materials is lower than that of ductile iron. Galvanizing treatment extends the service life, resulting in a lower total life cycle cost.
Customizable to project needs
Available in different bar sizes, thicknesses, and spacing options. It can be adjusted based on load requirements and installation conditions.
Typical Application Scenarios
1.Municipal Roads：Rainwater outlets on urban arterial roads, secondary roads and sidewalks for rapid drainage of road ponding.
2.Industrial Parks：Drainage systems in factory workshops, warehouses and loading areas to intercept waste residue and debris.
3.Residential Communities：Rainwater collection outlets in community roads, parking lots and green belts to prevent sediment from clogging pipelines.
4.Commercial Plazas：Ground drainage in shopping malls and pedestrian streets, balancing aesthetics and practicality.
5.Transportation Hubs：Outdoor platform drainage in airports, high-speed railway stations and ports, adapting to high-flow rainwater environments.

FAQ
Q: 1. What is the difference between 316 and 304 stainless steel grating?
A: The main difference is corrosion resistance. Stainless Steel 316 contains molybdenum, which helps it perform better in environments exposed to salt, chemicals, and moisture. It's a better option for marine or harsh conditions, while 304 is more commonly used for general applications.
Q: 2. Why choose serrated grating instead of plain grating?
A: Serrated grating offers better slip resistance. The toothed surface provides extra grip, especially in wet, oily, or outdoor conditions, making it a safer choice for walkways, platforms, and stairs.
Q: 3. Is a stainless steel grating suitable for marine environments?
A: Yes, it's widely used in marine and coastal areas. Its resistance to salt and corrosion makes it a reliable option for long-term use in these environments.
Q: 4. What load capacity can the grating handle?
A: The load capacity depends on the size, thickness, and spacing of the bearing bars. It can be designed to meet light, medium, or heavy-duty requirements based on the application.
Q: 5. Does stainless steel grating require maintenance?
A: Maintenance is minimal. stainless steel naturally resists corrosion, so it doesn't need painting or protective coatings. Routine cleaning is usually enough to keep it in good condition.
Q: 6. Can the grating be customized?
A: Yes, it can be customized in terms of panel size, bar spacing, thickness, and load capacity to fit specific project requirements.
