Asbra Suregrip is produced in an electric furnace at temperatures exceeding 2200° C. The hardness of the granules is second only to that of diamond; similar materials are used for precision grinding wheels.
Paving, Stairs, Landings, Ramps, Loading Docks, Service Stations, Patios, Factories Floors, Public Buildings, Swimming Pools, Schools, Shopping Centres, Parking Stations, Hospitals, Epoxy and Polyester Finishes.
The density and size or roughness of granules needed to achieve appropriate slip resistance depend on many variables. For instance, the gait of pedestrians in open public areas is often faster and less cautious than in areas readily discerned as private and enclosed. The frictional resistance of smooth porous surfaces varies significantly from wet to dry. All grades of Suregrip granule impart slip resistance, but the grade should relate to all anticipated service conditions generally as follows:
Asbra No. 1 Suregrip: 2000 micron Steep inclines, ramps, hazardous areas, etc
Asbra No. 2 Suregrip: 1100 micron Industrial paving, pedestrian walkways
Asbra No. 3 Suregrip: 600 micron Stairs, landings, loading docks, platforms, schools, hospitals
Asbra No. 4 Suregrip: 300 micron Industrial paving, stairs and landings. Also used for filling abrasive slip resistant grooves in stair treads usually 15mm (2 bars).
Asbra No. 5 Suregrip 225 micron Swimming pools, resin floors, hygienic floors
Finer grades are available for special applications. All micron sizes are approximate and subject to sieve tolerances.
Asbra No. 2 Pearl: Also available in No. 3, 4 and 5. Use for ornamental paving, swimming pools, resin floors, hygienic floors and industrial paving.
