Product Features:

• Advantages: SlipNOT® galvanized steel expanded metal stair treads provide a durable walking surface but features benefits like grating which allow for drainage and air flow.  SlipNOT® galvanized steel expanded metal treads ensure slip resistance for many years to come.
• Availability: SlipNOT® slip resistant galvanized steel expanded metal stair treads are custom formed in order to meet specific project requirements.
• Durability: Galvanized steel expanded metal stair treads coated with SlipNOT® have a file hard surface between 55 – 63 on the Rockwell “C” scale and has a bond strength of at least 4,000 psi.
• Protection: Steel products require a protective finish such as paint or galvanizing.  Steel products can rust easily if exposed to moisture.  Steel products should be primed, painted or hot dipped galvanized to prevent corrosion.  Hot dipped galvanizing is the preferred method for corrosion resistance.  (Guidelines for Galvanizing)
• Fabrication: Non-slip galvanized expanded metal stair treads are formed to job specifications.  Treads can be formed into a channel to completely cover an existing slippery stair.   (Fabricating Instructions)
• Application: SlipNOT® galvanized steel expanded metal stair treads are easily retrofitted over existing concrete, grating or unsafe diamond checker plate assemblies.  Non-slip expanded metal stair treads can be welded directly onto current treads or can be bolted in place.  Mid-point and top formed landings are also available.
• Slip Resistant Standards: SlipNOT® galvanized steel expanded metal stair treads meet and exceed all the requirements for an ASTM / ANSI slip resistant surface and are registered slip resistant with Underwriters Laboratories per the UL 410 standard.  SlipNOT® coefficient of friction is greater than or equal to 0.85. (Standards and Test Requirements)
