Combining traditional building techniques, quality manufacturing and third-party agencies who offer random inspections, testing, and certification services for quality control, SHS modules are built in strict accordance with appropriate local, state, and national regulations and codes. Due to the need to transport modules to the final site, each module must be built to independently withstand travel and installation requirements. Thus the final module-to-module assembly of independently durable components yields a final product more durable than conventional structures.
