The Duggan Profiles range of Eaves Beams comprises 2 section depths in 2mm material and a choice of two distinct material finishes. Users may choose between conventional hot-dip (galvanised) material while an alternative white prepainted steel is available for applications where improved aesthetics or additional anti corrosion protection is desired.
Refer to Material Specification (Galvanised) and Material Specification (Prepainted) for more detailed information.
Eaves Beams from the Duggan Profiles range are roll formed in lengths up to 20m and in angular increments of 1 degree up to 30 degrees.
Eaves Beams may not be produced with angles less than 90 degrees.
Sizes and dimensions
EAVES BEAM SECTION OPTIONS (GALVANISED)
Product Code | Section Dept (mm) | Thickness (mm) | Angle (Degrees) | Finish |
---|---|---|---|---|
DP-EBG180/200/00 | 180 | 2 | 0 – 30 | GALV |
DP-EBG210/200/00 | 210 | 2 | 0 – 30 | GALV |
EAVES BEAM SECTION OPTIONS (PREPAINTED)
Product Code | Section Dept (mm) | Thickness (mm) | Angle (Degrees) | Finish |
---|---|---|---|---|
DP-PEB180/200/00 | 180 | 2 | 0 – 30 | PREPAINTED |
DP-PEB210/200/00 | 210 | 2 | 0 – 30 | PREPAINTED |
Note:
The last two digits of the product code denote the angle. All the codes above specify an angle of Zero degrees, to specify an angle greater than Zero the last two digits should be replaced with the required angle. Example: DP-EBG 180/200/06 denotes a Galvanised Eaves Beam of 180 depth with an angle of 6 degrees.
Eaves Beams are available in a range of 2 section depths: 180 or 210mm.
Both depths are available in 2mm steel. The table above lists the available sizes.
Eaves Beams are specified by product code. The codes are defined as per the following examples:
Example 1: DP-EBG180/200/10
DP: Duggan Profiles, used as a prefix for all our sections
EBG: Eaves Beam Galvanised, this defines the profile and distinguishes it from purlins, rails or Cee sections. It also indicates the finish required.
180: The first 3 digits denote the section depth in mm
200: The second block of digits denotes the thickness (2mm).
10: The final block of digits denotes the angle of the Eaves Beam, 10 is 10 degrees, 06 is 6 degrees etc.
Example 2: DP-PEB210/200/20
DP: Duggan Profiles, used as a prefix for all our sections
PEB: Painted Eaves Beam, this defines the profile and distinguishes it from purlins, rails or Cee sections. It also indicates the finish required.
210: The first 3 digits denote the section depth in mm
200: The second block of digits denotes the thickness (2mm).
20: The final block of digits denotes the angle of the Eaves Beam, 20 is 10 degrees.
Typical profile dimensions are indicated, however it should be borne in mind that tolerances associated with the roll forming process means deviation from these nominal indicators is inevitable. The angle may be formed from zero up to 30 degrees in increments of 1 degree.
Eaves Beam Punching
Standard gauge lines for cleat and anti-sag holes are 90mm from the top and 60mm on the bottom flange however 14 or 18mm holes may be punched at any position on the section if requested. The standard hole size for cleat connections to the structure is 18mm to suit M16 bolts (Refer to the section on Eaves Beam Cleats for additional information). Holes for the anti sag strut connection are 14mm to accommodate M12 bolts. This is illustrated in the diagram below.
Length
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.
Cleats.
Eaves Beams connect to the supporting steelwork by means of 4 x M16 bolts and a fabricator supplied connection cleat. Duggan Profiles does not provide Eaves Beam Cleats. The standard connection details is shown below.

Overview:
Anti sag support for Eaves Beams is provided by Eaves Struts in conjunction with Eaves Strut Cleats and Eaves Strut to Purlin Cleats and all supported off a rigid structural member such as the cold-rolled sections shown in the images below. Where these are used, connection may be to the bottom flange or the centre web. The preferred option is connection to the web centre as risk of torsion of the cold-rolled member under load is less likely. This option does however require much free space, unobstructed by building members such as tie beams or insulated gutters. Where the path of the Eave Strut is obstructed the alternative arrangement may be considered.

Duggan Connection Macros
In common with the systems of other manufacturers the Duggan Prosigma installation includes a suite of connection macros which may be accessed as shown below.
Purlin/Rail to Column/Rafter
This creates a cleat connection for both the Sigma and Cee sections. The following options are available:
- Prepainted or Galv sections may be used
- The type of Cleat may be defined
- Sleeves may be used
- Rafter Stays may be used
- Firewall slots may be used
- Orientation holes may be added
Simply supported rail to column
This creates a cleat connection for both the Sigma and Cee sections where the members are inset between columns/rafters.
The following options are available:
- Prepainted or Galv sections may be used
- The type of hot rolled cleat may be defined (Duggan cleats are not suitable)
- Cleats may be slotted
- Members may be Notched around columns
- The inset distance may be varied
Eaves Beam to column
This creates an Eaves Beam cleat connection. The following options are available:
- Prepainted or Galv sections may be used
- Bolt-on or Weld-on cleats may be used
- The stock size may be defined
Note: Duggan Profiles do not supply Eaves Beam Cleats, these must be fabricated as part of the structural steel.
Connections for Cee Sections
This creates a connection between the following:
- Cee‘s and other Cee’s
- Cee’s and Eaves Beams
- Cee’s and columns/rafters
The following options are available:
- Prepainted or Galv sections may be used
- End Flanges may be used instead of cleats
- Hot rolled cleats may be used
- Notching may be used
Note: Use the Vertical Cladding Rail macro for connecting Cee’s to Sigma sections.
Vertical Cladding Rail connection
This creates all connections for the Vertical Cladding Rail (VCR). The following options are available:
- The horizontal rails may be any type of Sigma or Cee
- The VCR must be a Cee
- Cleat connections to columns may be defined
- Cover channels may be defined and used where required
- Tie Ropes may be used
Hip Connection
This creates a cleat connection between a Sigma or Cee and a hip rafter. The following options are available:
- The purlins may be any type of Sigma or Cee
- Weld-on or Bolt-on cleats may be used
Note: These cleats must be supplied by the fabricator.
Connection for Eaves Struts & Angle Struts
This creates the end connections for the Eaves Strut and the Angle Strut. These are standard connections and no adjustment is required however the following two connection options for the Eaves Strut are available:
- Eaves Strut connected to purlin web
- Eaves Strut connected to purlin flange
Purlin and Rail Tie connection
This creates the connections for Tube Struts, Tube Ties, Threaded Rod Ties and Apex Ties. It also makes provision for the inclusion of Tie Ropes. The following options are available:
- Sigma or Cee sections may be used
- Any Type of Tube Strut may be used
- Ties may be connected end to end or staggered (Anti sag requirements for Curved Roofs require staggered ties)
- Counterformed holes with countersunk bolts may be used
Connection for Tie Rope
This connects Tie Ropes with Tube Struts, Tube Ties, Angle Struts and Vertical Cladding Rails (VCR). The following options are available:
- Sigma or Cee sections may be used as the purlins or rails
- The anchor point at the column/rafter may be adjusted
- The anchor bracket at the column/rafter may be changed
- Tie Ropes can be inset for purlins/rails between rafters/columns
- Counterformed holes with countersunk bolts may be used
Cleader Angle Connection
This calculates the length of Cleader Angle required but does not create a connection. Duggan Profiles supply Cleader Angle in 6m lengths for screw fixing on site.
Service Holes
This creates a Service Hole in Sigma sections 235 and deeper and all Cee sections. There are no user defined parameters for this macro and the hole must be applied on the centreline of the section.
How to create an order:
Cold rolled may be ordered from within the StruCad environment by selecting the “Duggan Cam” option on the cold rolled menu.
The dialog box below appears. The order may include everything in the model or may be broken down by Phase, Finish, Prefix etc., in fact Duggan Cam allows ordering of coldrolled based on any user attribute.
- Choose to order “All” or create the order based on one of the available user attributes.
- Check if there are any non standard items. Items may appear non standard for various reasons such holes not on expected gauge lines or items too long to make. If an item cannot be manufactured it must be edited before ordering. Drawings of non standard items should be included with the order.
- Enter delivery details.
- Click “Generate CAM”.
- Two files are created and saved to the folder you selected (Model directory/COLDCAM/ by default). These two files are “modelname”.asp and “modelname”.xml and they contain the list of non standard items and the order details respectively. Attach these 2 files to an email along with drawings of any non standard items and send them to your normal sales contact. Your order is now placed.
