MMFG Announces Major Changes For Duradek Fiberglass Grating

Morrison Molded Fiber Glass Company (MMFG) of Bristol, Va., recently announced that major changes in Duradek® fiberglass grating have recently been made to improve and upgrade the product and make it more readily available to the customer.

Over one million dollars' worth of the new product is now in stock and can be shipped within 48 hours to a customer anywhere in the country.

Duradek is manufactured by the AFC Division of MMFG located in Chatfield, Minn. The changes to Duradek are described below.

A surfacing veil is standard on all ARC gratings (including polyester grating). This enhances both corrosion and UV resistance.

All Duradek gratings (including vinyl ester) are fire-retardant. This means they meet all the requirements of Class 1 on ASTM E-84 and the self-extinguishing requirements of ASTM D-635.

All Duradek gratings will have a UV inhibitor added to the resin. UV coatings remain as an option to be used only when UV inhibitors are not considered adequate for the application.

UV coating is still the best long-term solution to UV exposure.

Now the construction of Duradek more closely parallels the construction of Extren fiberglass pultruded structural shapes.

All Duradek gratings have a new cross-rod spacing of 6 inches center of bearing bar to center of bearing bar. This makes the product more acceptable and gives a higher yield when complex field cutting is required.

Cross-rod spacing (12-inch) is also available with a reduction in price.
