Fiberglass Grating Manufacturers Council


The Fiberglass Grating Manufacturers Council (FGMC) is one of ACMA's Composites Growth Initiative (CGI) Committees. This specialty industry committee is focused on growing fiberglass grating products used in a wide range of markets from construction, industrial, and oil and gas. The committee is currently focused on educating end users by developing a new design standard for fiberglass grating.

Mission Statement

The mission of the FGMC is to develop, maintain and promote the usage of a ASCE/ANSI Nationally accepted Fiberglass Grating Manual. Each FGMC member manufacturer produces grating products to meet and exceed the exacting standards as set forth in this document. As such, the council works to promote the usage of fiberglass grating specifications among architects, engineers, designers, specifiers and others.

FGMC's primary objective is become the leading source of information on composite grating and to develop technical information to educate and assist potential users of composite grating.


There are currently 10 companies that belong to ACMA's Fiberglass Grating Manufacturers Council.  Eight are fabricators; the remaining 2 are material suppliers and distributors.

Since the inception of the FGMC in 1997, the major focus of the manufacturers have been to educate end-users on the safe design and use of composite grating, both pultruded and molded grating.  A major component of this education was the creation of a design standard that engineers, designers, and specifiers could use to help them use FRP composites grating.  The members collectively worked together to perform round robin testing of commercially available products to determine the mechanical properties of the FRP grating products that were used to build the many design tables included in the standard.  The success of the FGMC was the development of a PreStandard Grating Manual.  The FGMC is now focused on converting the PreStandard document into an ANSI approved and nationally recognized standard. A summary of the ANSI Standard development can be found here.
