About Fibergrate

50 years of building safe and innovative environments for people to work, live and play.

In 1966, William C. Coonrod invented fiberglass molded grating in his Dallas, Texas, garage. That first panel was the beginning of Fibergrate. We are now an international company with a presence in 11 countries, and our customers have installed Fibergrate products on projects in more than 40 countries on 7 continents. 

Even after 50 years of growth, we still have the heart of that small company William started.

We are constantly looking for ways to further enhance the products and services we provide. We still believe our clients are our partners, and we believe in the power of local presence and support. We will be with our customers on every project, side-by-side, even joining them on the job site to ensure their success.

We are manufacturers, engineers, drafters and fabricators.

We know safety is paramount. Cost is important, and the structures our customers build reflect who they are. Our proven engineering capabilities and unmatched knowledge of composite solutions support our customers’ needs for safe, innovative and cost effective solutions.
