Bolted tanks are made Glass-Fused-to-Steel that are manufactured and finished offsite, greatly reducing the time and labor involved in the field. Once delivered, each section is erected, sealed with gaskets and bolted to adjacent sections. This results in an installation process that is quick and easy, far faster than installation of concrete or welded tanks, and it is not subject to the weather delays that often stall the installation of competing designs.
