Rubb has recently finished fabrication of a new salt storage facility for the City of Sanford, Maine. Rubb provided several options to the town over the course of two years.
The City of Sanford Municipal Government selected a 70ft (21.34m) x 80ft (24.39m) BVE Rubb structure with 16.4ft (5m) sidewalls.
The storage structure was designed to meet 70 psf ground snow load and 90 mph wind load with a 3 psf collateral. The City of Sanford favours the Rubb design because the white roof provides a naturally lit interior and the structure enables flexibility for future growth.
This structure will provide a salt storage capacity of 2,686 tons. The leg trusses and gable columns are powder coated to provide another layer of protection from the highly caustic nature of salt.
