Design criteria

Rubb buildings are designed in accordance with USA Building Regulations with respect to wind and snow loads.


Rubb buildings are designed in accordance with US Building Regulations with respect to wind and snow loads. The design is in strict accordance with the relevant local codes and current International Building Code (IBC). We also offer buildings around the world designed to suit local conditions and code requirements. Our past projects have been designed to sustain wind speeds up to 135mph and snow loads up to 200 lbs/sq ft. The building framework and cladding membrane are structurally analysed using appropriate non-linear techniques and software.

All structures manufactured by Rubb Buildings Systems are designed in strict accordance with local building codes and the 2012 International Building Codes (IBC) and the International Fire Code(IFC).
