Heavy- Duty Q235 Steel Drainage Gratinofor Efficient Water Drainage Systems

Advantages

• High-Strength ConstructionOur drainage gratings are made from premium materials, including high-grade stainless steel and sturdy cast iron. The stainless-steel versions can bear loads of up to 8,000 kg, making them perfect for long-term use in high-traffic locations such as industrial parks and commercial driveways. This high strength reduces the need for regular replacements, ultimately saving both time and money.
• Exceptional Drainage CapabilityDue to a meticulously designed aperture pattern, our gratings deliver outstanding drainage performance. They can handle water discharge of up to 10,000 liters per minute. The carefully optimized hole size and arrangement prevent blockages from debris while enabling swift water drainage, which is crucial in flood-prone or heavily rainy regions.
• Anti-Slip SurfaceSafety is our priority. Our gratings feature an anti-slip surface. Whether wet from rain or covered with industrial fluids, the surface provides a friction coefficient of no less than 75, significantly reducing the likelihood of slips and falls. They are well-suited for areas with both pedestrian and vehicle traffic.
• Customizable Design ChoicesWe understand that different projects have distinct needs. Our gratings come in a range of shapes (square, rectangular, circular) and sizes, and hole patterns can be customized. For example, in a recent project, we supplied gratings with a unique slotted structure for the drainage system of a modern architectural complex.
• Corrosion ResistanceCorrosion can be a major issue in severe environments. Our gratings, especially those made of stainless steel or treated with anti-corrosion coatings, have high resistance. They can withstand exposure to corrosive substances like salts and acids for over 20 years with little degradation, making them ideal for coastal areas and chemical plants.

Material

• Load-Bearing Flat BarWe offer Q235A carbon steel as a cost-efficient strength option, or stainless steel (304/316) for improved corrosion resistance.
• Cross MemberAvailable in Q235A or 304 stainless steel, and can be round, twisted square (ranging from 5×5mm to 8×8mm), square, or hexagonal steel for enhanced stability.

Dimensions

• Flat SteelThe thickness spans from 3–10mm (e.g., 25×3mm–100×10mm), and the width changes based on load requirements.
• GridThe center-to-center spacing of flat steel can be 30/40/60mm; the cross-bar spacing is 100/50mm.
• OverallStandard sizes are available, and customization is possible. The standard width is 995mm with a 5mm installation clearance.

Load-Bearing Capacity

• Light-DutyWith a load capacity of 25 tons/m², it is ideal for residential walkways, parks, and parking areas for light vehicles.
• Medium-DutyRated at 70 tons/m², it is perfect for factory areas and ordinary roads with vehicles weighing less than 20 tons.
• Heavy-DutyCapable of bearing 140 tons/m², it is designed for heavy-traffic areas such as main roads and industrial docks.

Surface Treatment

• Hot-Dip GalvanizingComes with an 85μm zinc coating, providing a service life of more than 20 years under normal conditions.
• Cold GalvanizingOffers a thin coating for applications with lower requirements.
• PaintingUses anti-rust paint in various colors for both visual appeal and corrosion prevention.

Drainage Efficiency

• Drainage AreaUp to 83.3%, enabling fast water drainage.
• ExampleAt a rainfall intensity of 50mm/h, it drains 1,000 liters of water per square meter every minute.

Anti-Slip Property

Applications

• City StreetsSteel grilles installed in road gutters can bear vehicle loads and quickly drain rainwater. This avoids water accumulation, ensuring the safety of both traffic and pedestrians.
• Industrial FacilitiesIn factory workshops and loading docks, the corrosion-resistant nature of our gratings can cope with chemical leaks. Their high durability also allows them to withstand the traffic of bulky machinery.
• Commercial EstablishmentsWhen installed at mall and office entryways, parking areas, and cellars, they effectively drain water. The anti-slip surfaces improve safety and prevent accidents.
• Residential CommunitiesFor private drives and footpaths, our gratings offer a practical drainage solution. Custom designs can be created to meet aesthetic needs while keeping the areas dry.
  Recreational SpacesAround park fountains, playground paths, and sports field locker rooms, they quickly drain water, keeping the environment clean and safe for visitors.

  
  

  FAQs：

• Q: What's the lifespan of the steel grilles?

• A: Our steel grilles, especially when hot - dip galvanized, can last over 20 years in normal conditions. Their robust material ensures long - term durability against wear and corrosion.

• 
  

• Q: Are they easy to install?

• A: Yes. Standard - sized grilles come with a 5 - mm installation gap for easy fitting. They can be quickly placed in position. Custom - sized ones also have straightforward installation procedures.

• 
  

• Q: How to clean the grilles?

• A: Regularly remove debris with a broom or shovel. For stubborn dirt or stains, use a mild detergent and water. In industrial settings, power - washing may be needed to handle heavy - duty grime.

• 
  

• Q: Can the grilles bear heavy loads?

• A: Absolutely. They're designed with different load - bearing capacities. Heavy - duty grilles can withstand up to 140 tons/m², suitable for areas with heavy - truck traffic.

• 
  

• Q: Do you offer customization?

• A: Yes, we provide customization in terms of size, shape, and hole patterns. This allows the grilles to meet specific project requirements, whether for aesthetics or functionality.
