Raised Expanded Metal3

Expanded Metal Grating

Engineer safe, durable industrial walkways with Xiongqian‘s premium expanded metal grating.

Manufactured from heavy-gauge carbon steel, stainless steel, or aluminum plate with larger diamond openings and deeper strands, our grating delivers maximum load-bearing capacity, superior anti-slip traction, and excellent drainage for catwalks, platforms, stair treads, and industrial walkways.

The one-piece construction eliminates welds and weak points, providing exceptional structural integrity and long service life in demanding environments. Available in standard and heavy-duty configurations with hot-dip galvanized, powder-coated, or painted finishes for superior corrosion protection. Fully customizable in materials, dimensions, and load ratings to meet your project specifications.

Product Overview

Xiongqian Expanded Metal Grating is a heavy-duty flooring solution engineered for industrial environments where safety, strength, and durability are paramount. Manufactured from thick-gauge metal plate through a precision expanding process, our grating features larger diamond openings and deeper, wider strands compared to standard expanded metal, delivering exceptional load-bearing capacity and structural rigidity.

The one-piece, seamless construction eliminates welds, rivets, and mechanical connections – removing potential failure points and ensuring uniform load distribution across the entire panel. This design provides superior fatigue resistance and long-term reliability, even in high-traffic areas subject to heavy foot traffic, machinery movement, and impact loads.

The raised diamond pattern delivers three critical performance benefits: first, the angled strands create aggressive anti-slip traction that remains effective in wet, oily, and dusty conditions; second, the open mesh design allows efficient drainage of water, oil, and debris – preventing hazardous accumulation; third, the grating‘s open structure provides excellent light transmission and ventilation, contributing to a safer, more comfortable work environment.

Constructed from heavy-gauge carbon steel, stainless steel, or aluminum with thicknesses from 2.0mm to 8.0mm, our grating is available in standard and heavy-duty configurations. The hot-dip galvanized, powder-coated, or painted finishes provide robust corrosion protection for long service life in demanding industrial, marine, and outdoor environments.

Whether you are constructing catwalks in a chemical plant, installing stair treads in a power station, or building maintenance platforms in a manufacturing facility, Xiongqian Expanded Metal Grating delivers the strength, safety, and durability your project demands.

Applications

Custom options

At Xiongqian, we understand that every industrial project has unique load, environmental, and dimensional requirements. That‘s why we offer focused customization for our expanded metal grating, allowing you to tailor the grating to your specific application needs. Below are the key customization options:

  1. Material Options – Choose from carbon steel (high strength, cost-effective, ideal for most industrial applications), stainless steel (maximum corrosion resistance, ideal for food processing, marine, and chemical environments), aluminum (lightweight, corrosion-resistant, ideal for elevated platforms), or galvanized steel (pre-galvanized for superior rust protection).

  2. Load Capacity & Thickness – Plate thickness from 2.0mm to 8.0mm determines load capacity. Configure standard-duty (up to 500 kg/m²), heavy-duty (up to 800 kg/m²), or extra-heavy-duty (1000+ kg/m²) to match your load requirements.

  3. Mesh Opening Dimensions – Customize LWO from 25mm to 200mm and SWO from 12mm to 100mm. Larger openings maximize drainage; smaller openings provide better foot comfort and fall-through protection for small objects.

  4. Sheet Dimensions – Widths from 600mm to 2400mm and lengths from 1000mm to 6000mm. Custom sizes available for seamless installation.

  5. Surface Finish – Select from hot-dip galvanizing (maximum outdoor corrosion protection), powder coating (any RAL color, scratch-resistant), painted finishes, or mill finish.

  6. Edge Treatment – Choose from cut edge (standard), folded edge (clean finish), hemmed edge (smooth and safe), or framed edge (with metal frame for maximum stability).

  7. Installation Accessories – Matching clips, bolts, frames, and mounting hardware available to complete your installation.

Beyond these standard options, we are always open to special requests – whether it‘s custom fabrication or packaging tailored for easy shipping. Our engineering team works closely with you from design to delivery, ensuring your grating meets every performance expectation. Contact us today, and we’ll provide a detailed quote with fast turnaround times.

FAQ

What is the difference between expanded metal grating and standard expanded metal?

 Expanded metal grating is manufactured from thicker plate (2.0mm–8.0mm) with larger openings and deeper strands, engineered specifically for high-load industrial flooring applications.

Standard expanded metal uses thinner plate (0.5mm–3.0mm) and is suitable for general-purpose applications like guards, screens, and light-duty uses.

Depending on thickness, material, and configuration, load capacity ranges from 500 kg/m² to over 1000 kg/m².

Please provide your specific load requirements, and our team will recommend the optimal configuration for your project.

Yes. The raised diamond pattern provides aggressive anti-slip traction rated R12–R13, making it highly effective in wet, oily, and dusty industrial environments.

We offer hot-dip galvanizing (maximum protection for outdoor/marine environments), powder coating (any RAL color), painted finishes, and stainless steel for maximum corrosion resistance.

Our team can recommend the best option for your environment.

Absolutely. We offer fully customized sheet dimensions, edge treatments, and fabrication including cutting, bending, and framing. Please provide your specifications and we‘ll manufacture accordingly.
