Seismic/windload-rated bases for secured rooftop equipment mounting are manufactured to International Building Code (IBC)/American Society of Civil Engineers- (ASCE) rated requirements. Manufactured to meet code, each base is custom-manufactured due to the varying specifications of rooftop units and IBC/ASCE requirements. Options include built-in roof pitch, additional height, built-in filters or sound traps, and a pressure-treated wood nailer. Bases are all-welded construction and are shipped to the jobsite in one piece if trucking permits. If not shippable as one piece, all corners are welded and the number of pieces is kept to a minimum. Delivery is usually within two weeks after receipt of order. Stamped calculations are available upon request.
