ABOUT PORTERCORP

PorterCorp, founded in 1964 as W. H. Porter, Inc., is a design, engineering and manufacturing company focusing on exterior structures and insulated building envelopes. PorterCorp was one of the first producers of SIPs (Structural Insulated Panels). PorterSIPs™  were an outgrowth of the marine industry where it was found that one of the best ways to build an economical, structural boat bottom was with a plastic foam core in sandwich construction with fiberglass. During the 1950's and 60's, Bill Porter was the R & D Manager for boat manufacturer Chris Craft Corporation. To expand PorterSIPs™ construction, PorterCorp developed the first tubular, bolt together steel frame with concealed bolts, and combined it with PorterSIPs™  to create an office building. This system is now marketed as Space-Frames™ . The following year, PorterCorp created the first park shelter using the same tubes and hidden bolt technology. This product, marketed as POLIGON®, started a revolution in public park structures. Recently, PorterCorp has expanded its shelter line to include a series of fabric covered steel frame structures marketed as Parasol™ .
