SIC Code 1623-21 Description (6-Digit)

Contractors-Post Tensioning is a specialized industry within the broader category of Water, Sewer, Pipeline, and Communications and Power Line Construction. This industry involves the installation of post-tensioning systems in concrete structures, which are used to reinforce and strengthen the concrete. Post-tensioning is a technique that involves the use of high-strength steel strands or bars, which are tensioned after the concrete has been poured and cured. This process helps to increase the load-bearing capacity of the concrete and reduce the risk of cracking and other forms of damage. Contractors-Post Tensioning companies typically work on large-scale construction projects, such as bridges, parking garages, and high-rise buildings. They are responsible for designing and installing post-tensioning systems that meet the specific requirements of each project. This involves working closely with architects, engineers, and other construction professionals to ensure that the systems are installed correctly and meet all safety and quality standards.
