From DEK to GRID

From DEK to GRID

Redco FRP (fiberglass reinforced plastic) pultruded grating is sold under two different names: DURADEK® and DURAGRID®. It’s not uncommon for our customers to ask – what is the difference between the two?

Before we answer that we need to give a quick primer on pultruded grating. The grating consists of the larger bearing bars locked in place by a proprietary cross-rod system. The bearing bars come in three profiles: rectangular, “I” and “T” profiles. The manufacturer pultruded this grating system with space between bearing bar spacing from 0-95%. Furthermore, the panels can be produced in 3′,4′, and 5′ widths and lengths of 8′, 10′, 12′ and 20′ lengths. This is not to mention the multipleI-6500 resin systems available.

As you can see, there are a large number of potential premutations for the panels between the differing lengths, widths, bar spacings and resins. To stock and record all of these would be impossible.

Instead, DURADEK® represents a collection of the most common pultruded grating profiles requested. These are stocked at Strongwell with readily available load tables for engineers. Therefore DURADEK® is known as Redco FRP’s “Standard Pultruded Grating.” A few grades of DURADEK® even compare in cost to molded grating. Offering a premium solution without the cost.

DURAGRID® is any grating which is custom pultruded for the customer. These are non-stock profiles and may be subject to a longer lead time and minimum order. However, DURAGRID® can solve problems in certain applications that DURADEK® cannot.
