Ontario Food Terminal had a large roofing area to cover with their new canopies and wanted a light-transmitting, low-cost and light weight solution. Plas-Tech was able to come to the table with an engineered, supplied and installed solution using TOPGAL 20mm standing seam custom green roofing system. It’s a multi-layered hollow fluted polycarbonate sheet which is extruded in a similar profile to conventional metal standing seam systems. The product is engineered for high snow & wind loads and can be installed on the purlins of the structural steel.
