Prefabricated columns are usually of steel and are secured by being bolted to their bases. It is fixed to anchor bolts, which are cast into the base of the structure. Fixing is achieved with nuts and washers attached to the anchor bolts. It is also possible to set the column at the correct height level and vertical position. The joint between column base and structure below should be grout as soon as possible after installation. After that the connection parts and grouting will work as reinforced concrete structure.
Prefabricated Piping is used in the vertical pipe shaft. Typical applications for prefabricated piping systems are cooling towers, swimming pools, waste treatment, aeration systems and filtration water systems.
