• ProSigma+ Sections Properties
• ProSigma+ Load Tables for Single Span Purlins

Material specification:

Prepainted Purlins, Rails, Eaves Beams and Cee sections from the Duggan Profiles ProSigma+ range are manufactured from organically coated structural steel with the following characteristics:

Steel Name: S390
Minimum yield strength: 390MPa
Corrosion protection: Hot-dip zinc coating
Coating designation: Z275
Coating mass: 275g/m2 (The minimum total coating mass both surfaces using triple spot test)

The painted finish to EN 10169:2010 is as follows:
Colour: Chalk White*
15μm thick flexible primer specially designed to resist corrosion, applied on both sides.
20μm thick flexible chemical and corrosion resistant Polyester Resin finish (Chalk White Top Coat) applied on both sides.
*The colour indicated is for information purposes only. Material samples are the only reliable indicator of colour and are available on request.

The material thickness is to EN 10143:2006 Continuously hot-dip coated steel sheet and strip. Tolerances on dimensions and shape.

The ProSigma+ range from Duggan Profiles is a range of purlins and rails suitable for use in agricultural applications.
It may be used with all types of conventional modern roof and wall cladding.

Design of the ProSigma+ profile has been in accordance with Eurocode 3, BS EN 1993-1 3:2006 and complemented by extensive physical testing. The result is an efficient range of sections which when used with appropriate anti sag systems combine to suit the widely varying conditions and loadings imposed by modern building techniques.
