About this business
Spiral Manufacturing supplies PVS underground pipe and ductwork for HVAC systems that need durable below-grade air delivery. Their polyvinyl steel-coated ductwork is designed for underground applications, including spaces where chemical exposure, moisture, soil contact, and abrasion resistance matter. Product options include vinyl-coated pipe, connectors, elbows, reducers, tees, register saddles, flat sheets, sealants, stack boots, and installation guidance. PVS offers strong load-bearing performance, corrosion resistance, and easier installation compared to some traditional materials.
