Loadmaster is an engineered roof deck system composed of a high tensile steel sections with thermal insulation and high performance Duraflex Mineral Board mechanically anchored to the steel sections with engineered attachments to provide structural composite strength. Through the use of engineered and tested structural composite action, the roof deck provides outstanding gravity load capacity, wind uplift resistance and diaphragm shear strength which stabilizes the building under wind and seismic loads.  The substrate’s resistance to high wind reduces expansion and contraction of the roof substrate, thus reducing stresses on roof coverings and potentially increasing the life span of the roof covering.  Loadmaster can be used in both flat and sloped structures with all types of roof coverings.
