Chem-Pruf is a wholesale building materials company based in Brownsville, Texas, founded on the engineering work of its founder William V. Pitt, who developed the first successful industrial fiberglass door designed to resist bowing, racking, and warping. The company specializes in corrosion-resistant fiberglass door systems, with a history of innovations such as a one-piece fiberglass stile and rail and permanently bonded door faces, and it has introduced market-firsts including atmospheric-resistant doors, solid fiberglass door frames, and unitized door systems pre-hung in matching frames. Target customers are professionals in environments where durability and corrosion resistance are critical, and the products address issues of door performance and longevity in challenging conditions. Chem-Pruf operates in the wholesale building materials industry and has established a niche in fiberglass door and frame systems, including fire-rated options, supported by a legacy of manufacturing expertise. A recent development noted is a partnership announced in March 2025 with KBO Sales Inc. to represent Chem-Pruf and related brands across Phoenix Door Company-related products.
