DURAGRID FRP Grating Offering a more Economical Alternative to Steel Grating

High commodity scrap prices for steel in 2011 had made a national retailer a theft target. The problem was the stealing of steel grating at the drainage systems in the large retail chain’s loading zones. Replacement costs of steel grating were very high due to longer fabrication times and higher steel prices. Another problem was aesthetic deterioration caused by the varying age of the steel grating and water runoff. The retail chain used wood as a temporary solution, but it became rotten in due course due to its nature.


The retail chain’s objective was to employ more number of non-metallic structural products in the drainage system to prevent trash and water buildup as well as theft. The chosen solution was DURAGRID pultruded grating from Strongwell.

DURAGRID 1.5" HD-5000 pultruded grating was used in eight installations to get extended years of maintenance-free service. FRP's light weight, high strength, easy-to-install characteristics enabled the retail chain to access its loading docks during installation, thus reducing downtime.

Since there is no decline in steel prices, the heavy duty HD grating will serve as a permanent, corrosion-free fixture in the loading zone of the retail chain while facilitating full drainage capabilities for the coming years.
