Tapered Roof:
Cellular Beam Application Technology.

See Also: Tapered Roof Case Studies

Cellular beams provide the most economical method of producing tapered steel members. Tapered beams can have cells of uniform size, cells of varying size or no cells.

Cellular beams achieve the two key requirements for a tapered cantilever: • great depth and huge inertia at the support • minimum depth and minimum weight at the tip Long cantilevers use two or even three different beam sizes to minimise the overall weight of the rafter with huge benefit to project cost.

There are often cases where the haunched portal frame is not appropriate to the needs of a client. These are likely to be: • where column widths need to be minimised • where eaves height is critical, eg. planning issues or expensive cladding • where a more aesthetically pleasing appearance is required • extreme spans beyond the range of portal frames In such cases a tapered cellular beam is often the optimum solution.
