Corefast offers many advantages over reinforced concrete.  As a modular off-site construction system, the manufacture of Bi-Steel panels and their assembly into Corefast modules takes place in a factory-controlled environment. This ensures accuracy of component manufacture and panel fabrication.

An additional key benefit of Corefast is that much detailing can be incorporated at the time of manufacture, eliminating the need to carry out this work on site. This can include the provision of door, window and service openings, plus the fixing of fin plates and floor angles for beam and slab connections as well as connections, for lift and stair units.

Corefast modules are typically eight to 12 metres long and weigh in the region of four to six tonnes. This facilitates convenient transportation by road and easy installation by crane on-site.

Once erected on-site, the modules are filled with concrete to create the full strength structure.
