Designed to create safe, slip resistant working and walking surfaces for a wide range of applications

SlipNOT® Process

SlipNOT® Metal Safety Flooring manufactures slip resistant metal flooring products. SlipNOT® transforms ordinary industrial flooring products to extraordinary, durable slip resistant safety products. From sure step bar gratings, high friction safety floor plates, permanently safe ladder rungs and rung covers to perforated and expanded metal retrofit plates, SlipNOT® is the preeminent long term solution for increased productivity and safety.

SlipNOT® Metal Safety Flooring Products are available in a wide variety of shapes and sizes customized to meet your project’s needs. The patented SlipNOT® process deposits molten metal in a random hatch matrix onto Steel, Aluminum or Stainless Steel substrates. This results in a file hard surface between 55-63 on the Rockwell C scale with a bond strength of at least 4,000 psi. This combination of extreme surface hardness and unparalleled bond strength means SlipNOT® is the most durable anti slip product available.

All SlipNOT® products can be fabricated, welded or otherwise treated like any other metal plate or grating because SlipNOT® is a metal on metal application. The SlipNOT® slip resistant surface does not alter the properties of the metal substrate; it only increases the coefficient of friction of the material.

SlipNOT® provides 100% rugged and durable surface coverage to all metal substrates. SlipNOT®’s proven durability, superior slip resistance and grit free surface ensures maximum worker safety while protecting expensive machinery and components from contamination. From food processing plants to office buildings, offshore drill rigs to steel mills, chemical plants to automotive plants, SlipNOT® is the proven answer for safe, productive environments.

SlipNOT® far exceeds all recommendations and standards for coefficient of friction specified by ANSI, NFPA, ADA, and OSHA.


Metal Surface Options

  • steel


    The steel SlipNOT® surface can be applied to steel or aluminum substrates. Applying steel to aluminum combines the lightweight properties of aluminum and the file hard surface of steel. SlipNOT® steel products are used in manufacturing industries where oil is present, among other diverse industries. The alloy is used for stairs, platforms, ladders, trench covers, road plates, conveyor lines and various other applications. Our steel coating is the coarsest surface available and ideal for high traffic areas where viscous liquids are prevalent, such as oil.


  • steel


    Stainless steel SlipNOT® can be applied to stainless steel or aluminum substrates. Our stainless steel on aluminum allows for a lightweight material and a chemical and corrosion resistant surface. SlipNOT® stainless steel remains completely slip resistant in countless environments, from food processing plants on catwalks, stairs, drain covers and platforms to walkways and stairs in public recreation areas, corporate offices and educational campuses. Our stainless steel products are registered by NSF International for use in food processing facilities and are used by companies such as Kraft, Tyson Foods, Nestle and many more. In addition to being chemical and corrosion resistant, stainless steel is aesthetically pleasing, versatile and ideal for commercial applications.

  • steel


    The aluminum surface is completely grit-free and is the ideal choice for projects where rust is a concern and that require a lightweight material. SlipNOT® aluminum products also provide a high strength-to weight ratio and are easily fabricated to project requirements. The aluminum surface is only applied to aluminum products and utilized in the aerospace, water/wastewater, utility and government industries, among many other industries. Floating docks, tank covers, walkways, access hatches, catwalks, defense vehicles and countless other applications require slip resistant aluminum products.

Surface Grade Descriptions

The SlipNOT® surface is applied to metal substrates by a plasma stream deposition resulting in peaks and valleys, creating a slip resistant surface. The SlipNOT® surface is available in three grades; Grade 1 (Fine), Grade 2 (Medium) and Grade 3 (Coarse). The different Grades available refer to the depth of the SlipNOT® surface.

  • grade

    Grade 1 – Fine

    The Grade 1 (Fine) surface has an average peak to valley surface depth of 0.010” – 0.012”.


    This grade is used in light duty applications or areas where a minimum surface roughness is desired. This surface produces the same high coefficient of friction as our Grade 2 (Medium). Any surface treatments, such as priming or painting, should not exceed 5 mils to prevent degradation of the SlipNOT® performance. Hot dipped galvanizing is not available for Grade 1 steel plates.


    Grade 1 (Fine) is available for all SlipNOT® surfaces.

  • grade

    Grade 2 – Medium

    This surface grade is applicable for nearly every situation. With an average peak to valley surface depth of 0.020”-0.025”; Grade 2 (Medium) SlipNOT® provides maximum traction, durability and longevity.


    Surface treatments to this grade should not exceed a total of 10 mils to prevent reduction of the surface coefficient of friction. For steel plates, hot dip galvanizing is the ideal surface protection.


    The Grade 2 (Medium) is available for all SlipNOT® surfaces.

  • grade

    Grade 3 – Coarse

    This surface is used in the most demanding environments. With an average peak to valley surface depth of 0.032”-0.038”.


    This grade provides maximum durability and longevity. For extremely high traffic or highly contaminated environments, Grade 3 (Coarse) SlipNOT® provides maximum traction. Hot dipped galvanizing is the ideal surface protection for steel.


    Grade 3 (Coarse) is only offered in our steel SlipNOT® surface. Not available in aluminum and stainless steel surfaces.

Finish Choices

The following is intended as a general informational guideline and may not account for all types of projects. Please contact a SlipNOT® representative for additional information. View our Priming and Painting Guidelines.

  • mill


    SlipNOT® is produced in a standard mill finish. There are no additives or paints applied to the product besides the slip resistant coating. Mill finish will be the raw material color.

  • mill


    SlipNOT® products can be painted with a water-based paint, however, care must be taken so the slip resistant properties of the surface are not compromised. Paint is available in black, safety yellow or customized to fit job specifications.

  • mill

    Powder Coated

    Powder coating has evolved as a popular dry finishing process used as a protective layer on metal products. It is becoming the preferred finish over traditional painting, providing durability and resistance to corrosion, chemicals, and weather elements. Unlike wet paint, powders don’t run or drip, providing a more uniform coating.  The vibrancy of powder coated parts tend to stay bright and fresh longer than wet paint.

  • mill


    SlipNOT® steel products can be offered with a hot-dipped galvanized finish to prevent corrosion. Galvanizing is performed in accordance with ASTM A123 or other appropriate specifications. SlipNOT® steel material can be galvanized after additional fabrication or processing. Please see our Guidelines for Galvanizing SlipNOT®.
