Stair Tread Steel Grating

Hengchen's stair tread steel gratings are engineered for safety, durability, and adaptability, making them ideal for stairways in diverse applications. Key features include:

High-Strength Materials: Crafted from galvanized steel, stainless steel, or FRP, our treads offer superior load-bearing capacity (e.g., H-20 ratings) and resistance to corrosion, suitable for harsh environments like chemical plants or marine platforms.

Anti-Slip Design: Serrated surfaces or MEBAC® coatings provide excellent traction, reducing slip hazards in wet, oily, or icy conditions, ensuring compliance with OSHA and ADA standards.

Open-Grid Structure: Allows passage of water, debris, and air, preventing accumulation and enhancing safety on outdoor or industrial stairways.

Customizable Dimensions: Available in standard sizes (e.g., 24–48 inches wide) or custom-cut to fit specific stair designs, with options for nosing (checker plate or abrasive) for added safety.

Corrosion Resistance: Hot-dip galvanized or powder-coated finishes extend lifespan (20–30 years), minimizing maintenance in corrosive settings like wastewater facilities.

Security Integration: Can be paired with razor wire or galvanized barbed wire for high-security stairways in military or correctional facilities.

1. Material Specifications

Purpose: Determines durability, corrosion resistance, and suitability for specific environments.

Common Materials:

Carbon Steel: High strength, cost-effective, typically galvanized for corrosion resistance (ASTM A123).

Stainless Steel (304/316): Superior corrosion resistance for harsh environments like marine or chemical plants.

Fiberglass-Reinforced Plastic (FRP): Lightweight, non-corrosive, ideal for offshore platforms or wastewater facilities.

Aluminum: Lightweight, corrosion-resistant, used in architectural or weight-sensitive applications.

Customer Benefit: Galvanized or stainless steel options ensure a 20–30-year lifespan with minimal maintenance, addressing concerns about durability and environmental exposure.

Example: Hengchen’s galvanized carbon steel treads are ideal for industrial stairways, resisting rust in outdoor settings.

2. Dimensions and Sizes

Purpose: Ensures compatibility with stair designs and project specifications.

Standard Widths: 24–48 inches (610–1219 mm), with common widths of 30 inches (762 mm) for industrial stairs and 36 inches (914 mm) for public access.

Standard Lengths: 24–60 inches (610–1524 mm), customizable to fit specific stair runs.

Depth (Bearing Bar Height): 1–2 inches (25–50 mm), with 1.25 inches (32 mm) being most common for balanced strength and weight.

Thickness (Bearing Bar): 3/16–1/4 inch (4.8–6.4 mm) for standard applications; heavier for high-load environments.

Nosing Options: Checker plate (1–2 inches wide) or abrasive nosing for enhanced visibility and safety.

Customer Benefit: Customizable sizes simplify installation and ensure compliance with ADA and OSHA standards, addressing concerns about project fit and safety.

Example: Hengchen’s 30-inch-wide galvanized treads with checker plate nosing ensure safe access in factory stairways.

3. Grid and Bar Spacing

Purpose: Affects load capacity, drainage, and safety.

Common Patterns:

19W4: 1-3/16 inch (30 mm) bearing bar spacing, standard for pedestrian traffic, offering high strength and cost-effectiveness.

15W4: 15/16 inch (24 mm) spacing, tighter grid for smaller openings, reducing debris passage.

11W4: 11/16 inch (17 mm) spacing, used for high-traffic or ADA-compliant areas to prevent small objects from falling through.

Cross Bar Spacing: 4 inches (100 mm) or 2 inches (50 mm) for added stability.

Customer Benefit: Adjustable spacing balances load capacity and safety, addressing concerns about debris accumulation or heel-catch risks in public spaces.

Example: 19W4 galvanized treads support heavy loads in factory stairways while allowing debris passage.

4. Load-Bearing Capacity

Purpose: Ensures treads can support intended loads without deformation.

Common Ratings:

Pedestrian Loads: 100–300 lbs/ft² (4.8–14.4 kPa), suitable for commercial or industrial stairs.

Heavy-Duty Loads: Up to 1,000 lbs/ft² (47.9 kPa) for industrial applications with equipment or machinery.

Vehicular Loads: H-20 rating (16,000 lbs/axle) for occasional vehicle traffic on service stairs.

Standards: Compliant with ANSI/NAAMM MBG 531 and ASTM A1011 for structural integrity.

Customer Benefit: Certified load tables ensure safety and reliability, addressing concerns about structural failure in high-traffic or heavy-load environments.

Example: Hengchen’s heavy-duty treads support maintenance crews on oil platform stairs, meeting H-20 requirements.

5. Surface Treatment and Finishes

Purpose: Enhances corrosion resistance, safety, and aesthetics.

Common Finishes:

Hot-Dip Galvanized: Conforms to ASTM A123, providing a zinc coating (70–100 µm) for rust resistance in outdoor or corrosive environments.

Powder-Coated: Available in colors (e.g., black, green) for aesthetic appeal in architectural settings.

Stainless Steel (Polished): For high-corrosion areas like marine or chemical plants.

Anti-Slip Coatings: Serrated surfaces or MEBAC® coatings for enhanced traction in wet or oily conditions.

Customer Benefit: Reduces maintenance costs and enhances safety, addressing concerns about environmental wear and slip hazards.

Example: Galvanized stair tread grating with serrated surfaces is used in wastewater plants, resisting corrosion and ensuring worker safety.

6. Installation and Mounting Options

Purpose: Simplifies assembly and ensures secure attachment.

Bolt-On: Pre-drilled holes for bolting to stair stringers, ideal for permanent installations.

Welded: For fixed, high-stability applications in industrial settings.

Clip or Saddle Mounting: For quick, removable installations in maintenance areas.

Customer Benefit: Reduces labor costs and installation time, addressing concerns about project timelines and ease of setup.

Example: Bolt-on treads with pre-drilled holes streamline installation in factory stairways, saving time.

7. Compliance and Certifications

Purpose: Ensures adherence to safety and quality standards.

Common Standards:

OSHA: Meets workplace safety requirements for slip resistance and load capacity.

ADA: Ensures accessibility with appropriate bar spacing and nosing for public spaces.
