Sunward Steel Buildings is a Denver-based manufacturer of pre-engineered steel buildings, in business since 1972 with more than 75,000 buildings delivered, and indoor pickleball facilities are one of the building types it markets. Its clear-span gymnasium-style structures span up to 200 feet without interior columns, which suits multi-court pickleball layouts with room for spectators and amenities, and buildings can be customized with insulation, skylights, ventilation, and climate considerations engineered to local wind, snow, and seismic codes. Sunward manufactures in US factories and ships kits nationwide, supporting projects from pre-planning and stamped engineering plans through delivery. For anyone planning an indoor pickleball facility, this is the building shell rather than the courts themselves.
