Abstract: Containers such as tanks, bins, cylinders, and the like, are constructed from a plurality of arcuate sections. The sections are formed on the ground, or other support surface, and lifted therefrom in a suitable manner to cooperate with other like sections during erection of the containers. Each section is formed by a plurality of strips laid on a concave jig so as to conform thereto. Beams reinforce the strips, which are tied together as by welds, and the like, to form a sheet. Shapers are advantageously removably attached to the sections for holding same to a required shape until the sections are connected together, and for holding adjacent sections in position relative to one another until suitable connection between the sections is made.
