Description of the Light Gauge Steel Frame Building System
Lundell Ltd is a design and manufacturing company offering high quality cold-formed structural steel to the construction industry. The system is available in an open or closed panel format, manufactured offsite and erected at site. They provide internal and external load bearing walls along with floor and roof panels. The panelised system is referred to as the Lundell Panel
The basic principle of Lundell Panel superstructures is that lightweight galvanised steel sections are used to form the structural elements of a building, based on proven engineering methods. Each storey height of the building frame is tied together and at each floor level with the floor construction which demonstrate adequate robustness as indicated in BS EN 1991 1 – 7 and UK National Annex to BS EN 1991 1 – 7.
Limits on scope
- Maximum 4 storeys for domestic housing using C section or lattice joists
- Bottom members in contact with foundations/sub-structure must be fully isolated from contact with moisture from the ground or external sources
- Masonry wall cladding cavities should be minimum 50mm and ventilated.
- Conventional cladding, such as timber cladding, should have a minimum 25mm drained back-cavity, or as recommended by the manufacturer.
- Rendered external thermal insulation systems and/or insulated brick slip cladding systems applied to steel-framed structures must have a minimum 25mm drained back-cavity.
- Stainless steel fixings, such as channels for masonry retention systems, must be isolated from the galvanised steel to prevent bi-metallic corrosion where there is a risk of exposure to moisture.
- Lundell Ltd and their approved technical design supply chain must be contracted for the design, manufacture and supply of the structures.
- The structural analysis and design for the structure is undertaken by approved Structural Engineers .
