Galvanized Serrated
Steel Grating is a durable, high-strength flooring solution widely used in industrial, commercial, and infrastructure applications. It is made from mild steel bars that are welded or pressed into a grid pattern, with serrated edges on the top surface for enhanced traction and safety.
- Serrated Surface: The jagged, ridged top layer provides excellent slip resistance, making it ideal for areas prone to moisture, oil, or debris.
- Galvanization: The steel undergoes hot-dip galvanization (or sometimes electro-galvanization), creating a protective zinc layer that prevents corrosion, rust, and environmental damage.
- Load-Bearing Strength: Engineered to support heavy loads, it is suitable for pedestrian and light vehicular traffic.
- Open Design: Permits drainage of liquids, debris, and air, reducing buildup and improving safety.
- Steel bars (typically rectangular or round) are arranged in perpendicular rows and welded at intersections.
- The surface is serrated through mechanical pressing or cutting to create 防滑 ridges.
- Galvanization adds a sacrificial layer that extends the product’s lifespan in harsh conditions.
- Industrial platforms, walkways, and stair treads.
- Drainage covers, trench gratings, and wastewater treatment facilities.
- Construction sites, factories, and offshore installations.
- Commercial areas like parking garages and loading docks.
- Durability: Resistant to corrosion, impact, and extreme temperatures.
- Low Maintenance: Galvanization minimizes the need for frequent painting or repairs.
- Safety: Slip-resistant design reduces accidents in wet or oily environments.
- Cost-Effective: Longevity and versatility make it a smart investment for many industries.
- Material: Mild steel (ASTM A36, Q235B, A1011) or stainless steel.
- Galvanization: Hot-dip galvanized to meet ASTM A123 standards.
- Load Capacity: Varies by bar size and spacing, typically ranging from 1.5 kN/m² to 50 kN/m².
- Standard Sizes: Customizable, but common bar heights are 25mm, 30mm, or 38mm with 30mm or 40mm spacing.
-
Pressed Welded Grating:
- Steel bars (typically rectangular) are welded at intersections under high pressure.
- Common for general flooring, walkways, and platforms.
-
Expanded Metal Grating:
- Created by slitting and stretching a flat steel sheet into a diamond-shaped mesh.
- Lightweight with good drainage; used in fences, barriers, and decorative applications.
-
Swage-Locked (Interlocking) Grating:
- Bars are mechanically interlocked without welding, allowing for easy disassembly.
- Often used in temporary structures or areas requiring frequent access.
-
Heavy-Duty Grating:
- Thick bars and close spacing for extreme loads (e.g., vehicle traffic in ports or factories).
-
Serrated Steel Grating:
- Features a ridged top surface for slip resistance, ideal for wet or oily environments.
- Hot-Dip Galvanization: Zinc coating for corrosion resistance (ASTM A123).
- Stainless Steel: Alloys like 304 or 316 for high corrosion resistance in marine or chemical settings.
- Painted/Coated: Epoxy or powder coatings for aesthetics or specialized protection.
