ProSigma+ (S390GD+Z275) - Sleeved Span - Loading Tables
ProSigma - Single Span Sleeved configuration
The Span Tables below have been created in accordance with EN 1993-1-3 (Eurocode EC3) and calculated by the Steel Construction Institute (SCI). Loads shown are based on lateral restraint being provided to the top flange of the purlin by the cladding. For purlin applications where no lateral restraint is offered by cladding please contact our technical department.
