SUPERGRIT SAFETY TREADS SUPERGRIT TREADS PROVIDE:
A heat-treated, corrosion resistant, extruded aluminum base with satin lacquered finish. The use of diamond hard aluminum oxide in the filler assures long tread life under heavy
pedestrian traffic use. Supergrit is appropriate for both inside and outside use.
SUPERGRIT FEATURES:
Extruded aluminum base - abrasive filler Lengths to order - up to 12'0" max. High content of aluminum oxide abrasive 11 standard colors - Colors extend throughout filler Noncombustible Protective tape available Nosings with replaceable top anti-slip inserts available, 8’0” maximum length
SUPERGRIT SPECIFICATION:
Provide Supergrit type __________________safety nosings as manufactured by Wooster Products Inc for interior and exterior stairs.
Nosing base shall be type 6063-T5 extruded aluminum. Anti-slip filler shall contain not less than 65% virgin grain Aluminum Oxide/Silicon Carbide
abrasive. Nosings shall be noncombustible as tested under Federal Test Method Standard No.
501a. Method 6411 Types of anchors are determined by the models, see literature. Nosings shall terminate not more than 4" from ends of steps for poured concrete stairs; for
concrete filled steel pan stairs, nosings shall be full length of steps less 1/8" clearance. Color shall be manufacturer’s standard color _______________ and extend uniformly
throughout the filler; black color will be furnished if no other color is specified. Nosings shall finish flush with the top of the traffic surface.
GUIDELINES FOR THE INSTALLATION OF METAL SAFETY TREADS OR NOSINGS INTO NEW CONCRETE OR STEEL PAN FILLED STAIRS:
The use of very large aggregate in the concrete mix may make placement of the safety nosing difficult.
Safety nosing placement may be difficult in concrete with very low slump. Place concrete into the stair forms or steel pans as quickly as possible; schedule pours so
as to install the metal safety nosings quickly before initial set of concrete occurs. Puddle the concrete; tamp the safety nosing to insure proper concrete formation around
the anchors. Remove protective tape (if used) as soon as practical. Order nosings or treads well in advance of the pour or installation date. Close stairway after pour; permit no use for 24 hours.
