Delta’s molded fiberglass stair treads are offered in two varieties: the DeltaTread and the DeltaGrate FabTread. DeltaTread stair treads are cut from DeltaTread panels measuring 22-1/4” x 10’-0”. The mesh of the DeltaTread is 1” x 6” with double bearing bars at the 6” intervals so that any stair tread with a length that is a multiple of 6” is always banded.
The DeltaTread panel design results in an efficient utilization ratio, i.e., 8 banded stair treads 2’-6” long can be cut from the DeltaTread panel with zero drop. These panels come with either a meniscus top non-skid or a gritted top non-skid.
The OSHA required non-skid nosing, built in to the leading edge of the tread for the first 1-1/4”, is always gritted, and is the same color as the rest of the panel.
The DeltaGrate FabTread is a regular 1 1/2” thick x 1-1/2” square mesh grating with a fabricated structural nosing. All of Delta stair treads, both the DeltaTread or the DeltaGrate FabTread, are available in all resins. And don’t forget about our fluorescent resins which are a big nighttime safety bonus!
|We Can Vary Glass Content Percentage! While DeltaGrate High Strength Compression Molded Grating comes standard with a 38% (average) glass content by weight, Delta can customize the glass content to suit the specific application. DeltaGrate can be manufactured with a 43% average glass content (DeltaGrate 43), or it can also be manufactured with a 32% glass content (DeltaGrate 32). These will be custom orders, therefore, please consult with us for delivery times.||Fire Retardant All DeltaGrate High Strength Compression Molded Gratings are designed to exhibit a minimum of a Class 1 flame spread rating when tested in accordance with ASTM E-84 flame spread rating Tunnel Test (comparable to UL 723, ANSI/NFPA No. 255 and UBC No. 8-1). DeltaGrate High Strength Compression Molded Grating are available in a variety of resins offering an array of flame spread ratings and smoke densities, from as low as 4 in flame spread rating and 1 in smoke density with our molded phenolic grating product.|
|Chemical Resistance With approximately 62% resin content, DeltaGrate High Strength Compression Molded Grating offers superb chemical resistance to a variety of acids and caustics. DeltaGrate High Strength Compression Molded Grating is offered in an array of corrosion resistant resins designed for any environment, from light or moderately corrosive environments to extremely corrosive applications.||Low Maintenance/Maintenance Free
With resin and pigment blended throughout DeltaGrate High Strength Compression Molded Grating, the grating will never require painting. Coupled with our corrosion resistant attachment systems, Delta provides maintenance-free walkway systems. You install it and forget about it!
|Lightweight DeltaGrate High Strength Compression Molded Grating 1” molded grating weighs 2.5 psf compared to 7.5 psf for 1” steel grating, and the 1-1/2” molded grating weighs 3.75 psf compared to 11.5 psf for 1-1/2” steel grating. DeltaGrate High Strength Compression Molded Grating weighs 1/3 the weight of steel gratings, resulting in easier installations and lower installation costs.||Impact Resistance DeltaGrate High Strength Compression Molded Gratings provide excellent impact resistance and are tested in accordance with ASTM 695-79 (1985) as established by the Fiberglass Grating Manufacturers Council (USA).|
|Non-Skid & Safety DeltaGrate High Strength Compression Molded Gratings are available in either a concave meniscus top or a gritted top. Each offers superior slip resistance over traditional steel grated walking surfaces. Many of our customers specify our DeltaTread fiberglass stair treads for their safe, non-skid characteristics alone.||Other Positive Features DeltaGrate High Strength Compression Molded Gratings are also:
• Electrically and thermally non-conductive
• Easy to cut and/or install
• Ultra-violet resistant
• Provided in a number of grating thicknesses and panel sizes
• Offers bi-directional strength characteristics
