GP42molded1.gif (11446 bytes)     F.gif (996 bytes)ibertred Grating Stair Treads manufactured from quality Fibergrate molded grating exceed tough OSHA standards for safety, strength, durability and corrosion resistance.  Fibertred is available in the same high performance resin formulations as Fibergrate molded grating and also provides excellent safety characteristics- slip resistance, non-conductivity and a low flame spread.

Unique cutting channels, spaced at 6" intervals, provide efficient utilization when custom fitting into stairways.  These channels also ensure that all standard stairtreads widths are terminated with closed ends.  A 1-1/2" wide gritted strip is molded into the lead edge of the tread for superior slip resistance.   (Additional support is required for treads exceeding 42" width).

Cost efficient, durable Pultruded Stair Treads are slip-resistant and non-conductive.  These stair treads offer the same level of safety, strength and corrosion resistance as other pultruded fiberglass products.  Designed for use in applications where wider support spans are required, Pultruded Stair Treads are available in 1", 1-1/2", and 2" thickness.

NOTES:
1. IT IS SUGGESTED THAT STAIR TREAD DEFLECTION BE LIMITED TO SPAN/150.  DEFLECTIONS BASED ON THIS RATIO ARE PROVIDED AT THE TOP OF THE TABLE.
2. DEFLECTIONS IN THE BODY OF THE TABLE ARE FOR CONCENTRATED LOADS OF BOTH 250 LBS. AND 500 LBS.  A CONCENTRATED LOAD IS APPLIED AT THE CENTERLINE OF THE TREAD, OVER A WIDTH OF 4" AND A DEPTH OF 6", STARTING AT THE NOSING EDGE TO SIMULATE HE LANDING OF A FOOT.
3. DEFLECTIONS ARE NOT APPRECIABLY DIFFERENT DUE TO STAIR TREAD DEPTH.  ACTUAL DEPTH WILL VARY DEPENDING IN STAIR TREAD CONFIGURATION.
