- ScotPanel series of roll formers that produces C-section are optimised for the web dimensions with additional web stiffeners placed at strategic locations.
- Additional web stiffeners result in a 15% increase in the axial compression capacity when used as wall studs in comparison with C-sections of similar dimensions without the additional web stiffeners.
- Lips in the C-section help in reducing the distortional buckling failure thereby resulting in increased capacities. The distortional mode of failure can be a dominant failure mode in certain cold-formed steel profile which has been addressed within the Scottsdale profiles.
- The automated swage and notch operations within these machines facilitate easier linear and staggered connection of the noggings for better in-plane restraints of the studs within a wall panel.
- Specialized end bearing tool option is available to eliminating the contact distance between the stud and the bottom plates thereby overcoming the connection failures. This helps in achieving greater connection capacities of a wall system as bearing of studs takes precedence over the connectors resulting in greater design capacities with thinner steel in comparison with the competition.
The ScotPanel series of roll formers have the capabilities to manufacture panels of the following type
- Wall
- Roof
- Ceiling
- Support frames
All the above-mentioned can be manufactured with the same machine using the same coil width. It can even roll roof and floor trusses for shorter spans. The roll formers have the capabilities to roll lipped channel section as thin as 0.55 mm which can be used in many non-load bearing to mild load bearing applications within the construction industry.
Ideally these profiles can be used in construction of a variety of structures. Some of the common use cases are mentioned below.
- Single and double storey residential constructions where roof and floor trusses are of shorter spans. Both load bearing and non-load bearing walls can be rolled out of the same machine.
- Town houses.

Some highlights of the specialised ScotTruss series of roll formers for the manufacturing of cold-formed steel trusses for residential and commercial applications are listed below
- Unlike the lipped channel sections, the top hat sections are placed about the strong (major) axis of the section geometry thereby making them more suitable for roof and floor truss applications to withstand higher bending moments induced on the truss top and bottom chord members.
- ScotTruss 6050 roll former can produce hat sections with a depth of 50 mm (2 in) which is well suited for residential and commercial applications.
- ScotTruss 6075 can produce a deeper 77 mm (3 in) top hat sections with a greater bending capacity as a resultant of the deeper webs. This in turn can be used in the production of trusses for industrial structures with higher wind and snow loads.
- Top and bottom flanges along with the lip lengths are carefully sized in these profiles to avoid distortional buckling failures thereby resulting in superior member capacities.
- ScotTruss top hat sections uses proprietary bolted connections with further strengthening through nylon spacers. This results in a superior and stronger truss connection in comparison to screwed connections.
- Loosening effect typically found in connectors due to aging is addressed by the specially built locking nut for the bolts affirming superior performance within the truss system in all applications.
Ideally these profiles can be used in construction of a variety of structures. Some of the common use cases are mentioned below.
- Mezzanine floors with heavy loads and large spans
