MATERIALS
Algrip Slip Resistant Treads are manufactured through a patented CNC laser
deposition process in which hundreds of rugged, custom alloy slip-resistant
laser deposits are delivered to each square foot of a substrate.

CARBON STEEL - plate and grating products intended for pedestrian traffic
are manufactured with ASTM A-1011 steel substrates. For structural appli-
cations, ASTM A-36 steel plate and bars are available. Carbon steel products
can be provided with a mill finish, painted or hot dip galvanized after fabrication.
Technical Slip Resistant Information is Provided Below Price Table.

NEW! Optional Finishes!

Our standard finish is a quick dry enamel in a variety of colors.
Now we are pleased to offer our products with a hot-dipped galvanized finish or in a
duplex system which is paint over a hot-dipped galvanized undercoat.

ORDERING NOTES:
1. The components listed here are used to complete a
    open riser system. Two tread depths are available.
    Select either a 9 1/2" or 11" tread depth.
4. Minimum galvanized tread order quantity is 10.
    For galvanized orders less than 10 add $125.00.
5. Special sizes quoted upon request.
2. Select desired tread width (36, 44, 48).
6. See price charts below tread drawings.
3. Select desired finish - Standard is gray enamel with black
    or blue also available galvanized treads are also available
    as standard. Other colors available upon request.
    Unpainted treads are available at the same price as
    enamel finish.

DURABILITY
While selection of the appropriate substrate is important, the true life cycle of safety
flooring is traditionally determined by the durability of the slip-resistant properties of the
walking surface. This is where your investment in Algrip begins to pay dividends.
algrip slip resistant stair treads
The traction providing laser depositions of Algrip Flooring Products have been tested for
hardness and adherence by independent testing laboratories. The results of these tests
assure that Algrip will provide unsurpassed service life.
Laboratory analysis has measured the hardness of Algrip traction providing custom alloy
laser depositions at up to 60 on the Rockwell C Scale. Under repetitious pedestrian and
vehicular traffic, these deposits will provide continuous, safe, effective service.
The cross-sectional photograph above illustrates the deep penetration of the symmetrical laser deposition into a steel
substrate. Laboratory tested, the deposition penetrates the substrate and is enclosed by a strengthened heat affected|
zone. The resulting bond strength, combined with the proven disposition hardness provides unsurpassed durability
regardless of wear or abrasion.
SAFETY
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.
treads
For these challenging applications, the
unique matrix application of Algrip laser
deposits provides unparalleled slip resis-
tance 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 laboratory setting by measuring for static coefficient of friction (CCF) in accord-
ance 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 work/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 indi-
cating 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 more
stringent 0.80 COF.
The following results demonstrate that Algrip Plate and Grating products exceed
published Federal Guidelines in all conditions!
