Conventional wisdom for using steel has been to maximize spans and provide universal products that fit nearly any building type. SGBS Intl. chose a rather unorthodox approach to find a solution. First, we determined that precast slab units, common in the mid-rise residential market, combined with a steel frame could offer speed, design flexibility and value. Although residential unit modules typically vary within a floor, they generally stack vertically for structural support, utilities and shafts. After considering the modular nature of residential construction, it was concluded that long-span precast slabs in combination with short span steel SGBS Intl. would be both appropriate and efficient. Our EnviroBeam™ overcame the issue associated with a standard wide flange beam sitting below the slab.
