The United States Bureau of Labor Statistics reports that over 20% of all compensable industrial injuries result from slips and falls. Often these accidents occur when liquids, lubricants or foreign materials have accumulated on floors, stairs or work platforms.

For these challenging applications, the unique matrix application of Algrip laser deposits provides unparalleled slip resistance in all directions. Plate products are manufactured with more than 1,000 deposits per square foot. Shoe and tire materials completely encircle and "grab" the deposits. Worker safety and employer protections are significantly enhanced with each installation of Algrip.

Slip Resistance and Coefficient of Friction (COF)

Slip-resistance is commonly tested in a laboratory setting by measuring for static coefficient of friction (COF) in accordance with ASTM procedure C-1028. This testing procedure assigns a value to the traction surface while that surface is tested under wet and dry conditions. Because the greatest concern for slip resistance relates to worker/pedestrian safety, this procedure can be further refined to test each condition using samples of two popular shoe sole materials, rubber and neolite (composition). The results of these tests are expressed in numerical values with higher values indicating increased slip-resistance.

Federal Guidelines for COF

The Occupational Safety and Health Administration (OSHA) recommends that walking surfaces maintain a minimum COF of 0.50. The Americans with Disabilities Act (ADA) recommends that level walking surfaces maintain a 0.60 COF and that surfaces for inclined ramps maintain a more stringent 0.80 COF.

The following results demonstrate that Algrip Plate and Grating products exceed published Federal Guidelines in all conditions!
