SPI Grating Systems provide an efficient and cost effective solution for all flooring, walkways and decking areas requiring long term performance in aggressive and corrosive environments. Constructed from glass reinforced thermoset resins, SPI grating is designed and manufactured with a structural integrity commonly associated with steel and aluminium, but without their corrosion problems. All pultruded profiles used in gratings were made of premium grade isophthalic polyester or vinyl ester resins and meet the fire retardancy requirements of UL94 V-0, ASTM D-635 and ASTM E-84. It contain nominally
70% E glass reinforcement. The pultruded load bar will be of high strength I-Beam design. All loading members shall be mechanically locked to each other via two spacing bars and central locking rod. Where anti-skid is required, a tough epoxy-quartz coating is applied to the surface of all loading members.

TRANSPARENT TO RADIO FREQUENCIES
Fibreglass composites do not interfere with electromagnetic and radio frequency transmissions. Safetread grating can be safely applied in towers and other structures used in the transmission of such signals.

NON CONDUCTIVE
Safetread can be used safely in electrical work areas. Special support conditions to prevent electrolytic corrosion are not required.

STABLE
Unlike many other fibreglass systems, the use of a double mechanical lock system to locate and space the load bars makes Safetread a permanently stable panel.

NON-SKID SURFACE
Safetread has a tough, quartz epoxy finish that will ensure the maximum in skid resistance and safety even in wet environments.

COST PERFORMANCE
Very favourable results have been demonstrated with Safetread emphasising low installation costs and long service life with minimum maintenance.. Safetread is designed using high strength to weight ratio pultruded structural composite profiles.

DIMENSIONS
Standard panel sizes are nominal 914mm (36 in) or 1219mm (48 in) wide by 3048mm (120 in) span. Other sizes are available to order to a maximum of 1219 mm (48 in) wide by 6096mm (240 in) span. Panel weight must be considered when ordering large panels. Special shape panels can be cut from standard width stock panels.

SAFETREAD STANDARD GRATING
Made with premium grade isophthalic polyester resin yielding excellent chemical resistance with high physical properties.

SAFETREAD FIRE RETARDANT GRATING
Also made with isophthalic polyester resin but with built-in fire retardant additives. Complies with ASTM E-84 and the self extinguishing requirements of ASTM D-635 and UL 94V-0.

SUPERIOR CHEMICAL RESISTANCE
A premium grade of vinyl ester resin is used to replace isophthalic polyester, in either standard or fire retardant versions.

COLOUR
Standard and fire retardant Safetread is made in Safety Yellow. Other colours can be made to order.

DESIGN
Safetread grating is engineered to meet the requirements of Australian Standard AS1657-1992. An exception is Series 600 Type 600 which exceeds the open area requirement of the standard.

STAIR TREADS
Constructed from the same high strength load bars as used in Safetread grating.
