The panel concept
Units are provided in flat-pack form and installed on site, made of heavy-duty steel structures and prefabricated Structural Insulated Panel (SIP) modules. In most cases, flat packs are transported to site in ISO containers for efficiency, security, and lowest cost. The basic structure consists of specially formed structural steel frames; floor and roof ring beams are part-welded and part-mechanically connected. Steel sections generally use cold-rolled channel sections in a specific form. Longitudinal main beams are braced together by bolting similar cold-rolled galvanized steel joints at floor levels. The standard arrangement supports up to three stories, with greater story heights achievable through detailed engineering.
