Example 1: DP-CSG205/65/150
DP: Duggan Profiles, used as a prefix for all our sections
CSG: Cee Section Galvanised, this defines the profile and distinguishes it from purlins, rails or Eaves Beams
205: The first 3 digits denote the section depth in mm
65: The second block of digits denotes the flange width in mm
150: The final block of digits denotes the thickness, 150 is 1.5mm, 180 is 1.8mm etc.

Lengths
Duggan Profiles can roll form its cold rolled products in lengths up to 20m. Customers should bear in mind the logistics of transportation and site handling before ordering sections of excessive length. If possible cold rolled sections should not exceed 14m for maximum ease of transportation.

Punching arrangement
Standard gauge lines for cleat connections are 20mm from top and bottom flanges as shown below. Anti sag ties typically connect to holes on the section centreline. In general all holes are 14mm to suit M12 bolts however 18mm holes are also available if specified. Counterforming along with End Flanging, notching, slotted holes, off standard punching and the provision of service holes are all options available with Cee sections. Refer to ProSigma+ Customisation for more in-depth information on the variety of additional services available.

Material specification (Galvanised)
Purlins, Rails, Eaves Beams and Cee sections from the Duggan Profiles ProSigma range are manufactured as standard from high proof strength steel for cold forming with the following characteristics to EN 10346:2009

Minimum yield strength (Rel): 450MPa
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 material thickness is to EN 10143:2006 Continuously hot-dip coated steel sheet and strip. Tolerances on dimensions and shape

Material specification (Prepainted)
Painted Purlins, Rails, Eaves Beams and Cee sections from the Duggan Profiles ProSigma range may be 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*
A 15μm thick flexible primer specially designed to resist corrosion, applied on both sides.
A 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.
