Fiberglass Doors and Door Assemblies from Chem-Pruf®

Fiberglass doors and door assemblies from Chem-pruf are engineered and manufactured to withstand the most corrosive environments. Every fiberglass door is custom made to your exact specifications. We carry sizes, styles, colors, windows, louvers and accessories to fit every need. Fiberglass doors and fiberglass door panels are made of heat-resistant, halogenated, flame-retardant polyester resins.  From chemical plants to pulp and paper mills to water and wastewater treatment plants, high quality Chem-Pruf® products perform flawlessly. We guarantee it.
Here's why. 

Every Chem-Pruf® product is custom made to meet the customer's unique specifications from exact dimensions to special options to specially-formulated resin chemistry. At Chem-Pruf®, all our doors, door frames, windows, louvers and accessories are assembled from fiberglass-reinforced polymer (FRP) components produced in house. Chem-Pruf® controls the entire process ensuring the highest manufacturing standards and strict quality control. The result is products of such quality that they set the standard in the industry. 

In 1974, Chem-Pruf® founder William V. Pitt designed, engineered  and built the first successful industrial door that would not bow-rack or warp. This remarkable door was made possible by a unique, now patented, one-piece fiberglass stile and rail system. Tough, corrosion resistant fiberglass plates which form the faces of the door were permanently bonded to the stile and rail to create the finished door. With an idea, a feat of engineering and a wealth of manufacturing know-how, Bill Pitt founded not only Chem-Pruf Door Company but an entire industry.

Today, Chem-Pruf® continues to set the standards. The number of industry "firsts" introduced by Chem-Pruf®  is impressive and continues to grow. Chem-Pruf®  received the first patent ever issued by the U.S. Patent Office for an atmospheric-resistant door. First to mold a solid, all-fiberglass door frame. First to tailor resin chemistry to match the exact conditions where the products will be installed. First to introduce a unitized fiberglass door system with the door pre-hung in a color-matching fiberglass door frame and all hard-ware installed at the factory prior to crating. First to offer 5-, and 10-, now 25-year warranty against failure due to corrosion. First to manufacture a complete fire-rated fiberglass door and door frame system certified and labeled by Warnock-Hersey.

To meet the needs of the industry, Chem-Pruf's product line has expanded over the years to include a wide variety of door options and accessories as well as wall windows and wall louvers. To better serve architects and engineers, a new, rapidly expanding website. www.chem-pruf.com went on line in 2002 providing AutoCad files and complete specifications for all of Chem-Pruf's products.
