About Calsak Plastics
Calsak Plastics, headquartered in Irving, Texas, was founded in 1972. The company began as a regional plastic sheet supplier and expanded into a nationwide distributor with seven branch locations across the United States. The company distributes a broad range of plastic materials — including acrylic, polycarbonate, HDPE, PVC, PETG, ABS, engineering thermoplastics such as acetal, nylon, UHMW-PE, and PEEK, composite panels, and marine-grade plastics — in sheet, rod, and tube forms. It holds exclusive U.S. distribution rights for Acrycast® cell-cast acrylic and offers proprietary lines such as PolyGuard® polycarbonate, Trident® marine plastics, LumaTek® PVC boards, and Aluplast® aluminum composite panels. Value-added services include CNC routing, CNC drilling, thermoforming, cold and heat bending, polished edge finishing, assembly, kitting, and cut-to-size cutting with a standard tolerance of ±0.030″. Fabrication is performed in-house at each branch, enabling most cut-to-size orders to ship within one to three business days. The company also operates a closed-loop recycling program at all locations. Calsak serves engineers, fabricators, procurement teams, and manufacturers across industries such as marine and boat building, architectural signage, construction, printing and graphics, aerospace, automotive, medical, retail display, data center, and advertising and art. Its materials are used for hulls, cabinetry, dock equipment, signage, cladding, glazing, printable substrates, data center containment panels, and medical device housings. The company differentiates itself by combining global sourcing with domestic fulfillment, routing orders from the nearest branch to minimize lead times. Technical sales specialists provide material selection, compliance review, and specification guidance. Proprietary brands are developed for specific performance demands rather than repackaged commodity grades.
