The low self-weight of siFramo is achieved through a combination of corrugated geometry and a premium grade steel to create solid structures.
Choosing an equivalent standard hollow structural section would result in a weight increase of more than 50%.
The engineering behind siFramo’s geometry
siFramo delivers greater strength compared than standard hollow structural box sections of the same size and thickness. The corrugated geometry enables supports to be lighter in weight than standard hollow structural box sections of the same strength.
Example: A 5“ double-flanged beam configuration is approximately 50% heavier than a siFramo section with similar load capacity.
