Product Features:

• Advantages: Steel perforated stair treads combine the benefits of both plate and grating which providing a strong, durable surface that is able to withstand harsh environments.
• Availability: Steel perforated stair treads are available in many different styles and spacing options to meet a variety of needs and applications.
• Durability: Steel perforated stair treads coated with SlipNOT® have a file hard surface between 55 – 63 on the Rockwell “C” scale and have a bond strength of at least 4,000 psi. (Guidelines for Galvanizing)
• Protection: Steel products require a protective finish such as paint or galvanizing.  Steel products can rust easily if exposed to moisture of any sorts.  Steel products should be primed, painted or hot dipped galvanized to prevent corrosion.  Hot dipped galvanizing is the preferred method for corrosion resistance.
• Fabrication: Steel perforated plate stair treads can be sheared, welded, flame cut, torch cut, laser or water-jet cut, plasma cut, countersunk and drilled for complete versatility, both in the shop and field.  Treads can be formed to specifications with nosing or formed to a channel. Treads are manufactured to specifications for thickness and depth. (Fabricating Instructions)
• Application: SlipNOT® steel perforated stair treads are easily retrofitted over existing concrete, grating or unsafe diamond checker plate assemblies.  Non-slip perforated stair treads can be welded directly onto current treads or stringers or can be bolted in place.  Mid-point and top formed landings are also available.
• Slip Resistant Standards: SlipNOT® steel perforated 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.
