DeltaGrate High Strength Compression Molded Grating

DeltaGrate High Strength Compression Molded Fiberglass Grating was developed for corrosive applications where light weight, impact resistant, corrosion resistant and slip resistant grating is a must. DeltaGrate High Strength Compression Molded Grating is a combination of glass rovings strategically positioned within thermoset resins to form a one-piece, high resin content product. This grating product is a better alternative to traditional steel grating products.

Quality Manufactured Product
DeltaGrate High Strength Compression Molded Grating is manufactured to ISO 9001 standards. Every panel of grating is subjected to a number of quality assurance inspections ensuring void free panels, full wet-out of the glass rovings, consistent resin-to-glass ratios, and consistent non-skid features. Complete traceability of resin batches and the glass utilized in every panel is maintained and can be provided as needed. U-V testing, chemical resistance tests, load capacity, and impact tests are also routinely performed.

Higher Stiffness
DeltaGrate High Strength Compression Molded Grating is manufactured using a proprietary method enabling a higher percentage of glass rovings to be introduced into the grating. Conventional open-top molded gratings are constructed with approximately 25-30% glass content by weight, whereas DeltaGrate High Strength Compression Molded Grating contains 38% glass content. The corrosion resistance of fiberglass grating is provided by the resin, and the stiffness is provided by the glass. Possessing a higher glass content results in a stiffer fiberglass grating. As a result, DeltaGrate High Strength Compression Molded Grating is 15-20% stiffer than the gratings produced by other manufacturers of open-top molded fiberglass gratings without compromising any of the other inherent qualities of molded fiberglass grating.

Additional information, benefits and features:

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
