SLIPNOT® Flattened Expanded Metal Stair Treads
NON-SLIP
Flattened Expanded Metal Stair Treads
Instead of throwing away worn-out diamond plate or slick bar grating, upgrade stairs by layering our slip-resistant flattened metal treads over the existing steps. SLIPNOT® offers an incredibly efficient way to reduce stair hazards without structural demolition. This single sheet of metal with an open diamond-mesh pattern ensures structural integrity without any welds or interlocked strands that could come apart.

Retrofitting Anti-Slip Expanded Metal Treads for Improved Safety
Stairway slip-and-fall injuries are a leading cause of workers’ compensation claims, but replacing entire stair systems to improve traction is often too costly and causes unacceptable facility downtime. Get all the premium safety benefits of SLIPNOT® technology at a fraction of the cost of a full stairway rebuild.
Our long-lasting non-skid expanded metal treads are designed to provide the following advantages:
- Flat, level surface: The flattened surface is less contoured than standard expanded metal. This makes it more comfortable for foot traffic while still providing good traction and preventing debris buildup.
- Optimal drainage: The characteristic pattern of expanded metal features uniform diamond-shaped openings that allow light, air, and liquids to pass. Maintain optimal ventilation and airflow with these metal treads installed over grating.
- Long-lasting capabilities: Our proprietary non-skid expanded metal coating creates a file-hard, high-friction retrofit surface that won’t flake or peel. The durable, non-skid expanded metal treads outperform temporary grip tapes and paints.
- Regulatory compliance: Keep your facility audit-ready with metal treads that exceed the coefficient of friction (COF) requirements for OSHA, ADA, and ANSI.
Specifications of High-Friction Expanded Metal Treads
SLIPNOT® flattened expanded metal ensures a level walking surface that meets your operational requirements:
- Substrate alloys: Available in steel, stainless steel, or aluminum to match your specific environmental and corrosive requirements.
- Thickness options: We typically supply 1/8″ thickness to ensure the retrofit does not drastically alter the stair’s rise-and-run dimensions.
- Grip levels: Choose from three grades — Grade 1 for fine, Grade 2 for medium, and Grade 3 for coarse (exclusively for steel in heavy-oil applications).
- Finishes: We offer a range of finishes, including mill, painted, galvanized, and powder-coated.

Grade 1 (Fine)
Light-duty applications or where a minimum surface roughness is desired

Grade 2 (Medium)
Ideal for most commercial environments and light rolling loads

Grade 3 (Coarse; Steel Only)
Drain Covers for rugged industrial use
Custom Fabrication for Various Facilities
We can customize these safety expanded metal treads to ensure a flawless, edge-to-edge fit over your existing stairs. Whether you need to cover the entire stair tread or apply it as a protective nosing on the leading edge, our experts can help
Fast Installation for Minimal Facility Downtime
Installing these long-lasting, non-skid expanded metal treads is a simple process that keeps the workforce moving. We offer multiple fastening options to ensure treads are quickly and securely attached with our high-traction surface coating.
Installation methods include welding, where the item is tack-welded directly to the bearing bars of existing grating or onto solid floor plates. Bolting provides a secure fastening to existing surfaces.
