ALGRIP® Slip-Resistant Metal Stair Treads, Tread Repair Covers and Nosings provide maximum protection against slips and falls on stairways. Unique laser-welded deposits deliver unparalleled durability and traction, making this technology a smart choice for high-traffic applications in workplace or public settings. ALGRIP Stair Tread Products are designed for easy cleaning and are particularly effective in environments where the accumulation of liquids, dust, grease or other substances creates slippery conditions.


Design Features

Available in a wide range of materials, sizes and finishes, ALGRIP Slip-Resistant Stair Tread Products are exceptionally versatile and can be implemented in both new construction and retrofit applications. Stair Treads are intended for use in the production of new stairways and are available in plate or bar grate configurations. Tread Repair Covers are formed to fit over top of existing treads for a quick and cost effective method of upgrading stairways already in service. Nosings are appropriate for both new and retrofit construction.

Ross’ patented CNC laser deposition process applies more than 1,000 rugged, custom-alloy deposits per square foot in a highly precise and uniform pattern. The superior bond strength of these deposits not only increases the useful product life, but also allows nearly any type of onsite fabrication without compromising the traction providing surface. And the smooth area between raised deposits helps deter the pooling of liquids and trapping of solids, which results in a product that exhibits exceptional self-cleaning characteristics.

ALGRIP is an ideal choice for a variety of applications requiring slip-resistant walking surfaces, such as:

  • New construction (treads)
  • Retrofit/repair over concrete or carpet (covers)
  • Spiral stairs
  • Mezzanines
  • Platforms
  • OEM equipment


Thousands of companies have chosen ALGRIP products to help mitigate their exposure to slip and fall risks. ALGRIP Stair Treads, Covers and Nosings are ideal for a wide range of project applications and industries including:

Technical Data

ALGRIP Slip-Resistant Stair Treads, Tread Repair Covers and Nosings are manufactured using technologically advanced machinery developed by Ross to ensure the highest level of quality and consistency. We start with the base material that best suits your application. Choose from various grades of lightweight aluminum, corrosion-resistant stainless or durable carbon steel in sheet, plate or bar grate form. Next, we laser-weld a minimum of 1,000 anti-slip deposits per square foot to the traffic side of the selected material.

These welded deposits penetrate the metal substrate to produce a permanent, sub-surface bond tested to a maximum hardness of 60 on the Rockwell C Scale and a maximum coefficient of friction of 0.97 (COF) in accordance with ASTM C1028-89. Finally, the material is custom fabricated, if needed, using a variety of processes and finishes to meet your specific project requirements. The result is a metal stair tread product with durability and slip resistance properties like no other.
