1 ABOUT ALBION SECTIONS LTD We are a specialist custom cold roll‐forming manufacturer, offering a comprehensive range of light secondary steel construction components for the construction and engineering industries. Part of the Sebdon Group of Companies, we have benefitted from continuous investment both in production and technical development. Using state of the art rolling mill, we produce one of the largest ranges of sections available. The structural framing system (SFS) offers stud profiles from 85mm to 300mm wide, with associated track profiles. This technical booklet is designed to indicate typical joining and connection details of the SFS system and should be read in conjunction with our SFS brochure. Our products are Quality assessed to ISO‐9001:2008 and carry the CE mark to BS EN1090‐1:2009, upto and including Execution class 4 according to BS EN1090‐2:2008. Albion’s Technical personnel are on hand to provide assistance. All information contained within this document shows typical detailing only. Reference should be made to

2 PRODUCT DESCRIPTION Albion SFS is a rapid construction method for forming external walling, high separating walls and load bearing frames in lightweight cold rolled galvanised steel section. Light Steel Framing has been utilised in many sectors of construction; residential (low & high rise), education, commercial and healthcare. As a form of ‘rapid dry envelope’, SFS may be installed in many conditions very rapidly allowing a building to become water tight. With high dimensional stability, galvanised steel sections do not shrink or expand to the same degree as traditional wet trades or timber giving a higher quality finish. SFS projects are designed using Albion’s in house design team and tailored design software. External Walling – Infill System Spanning vertically between the primary structure (steel beams or concrete slabs), ‘U’ tracks are fixed at the top (head) and bottom (base) of a single storey bay between columns. ‘C’ studs are then fixed into the ‘U’ tracks at typically 600mm centres to co‐ordinate with insulation, sheathing boards and drylining boards. Structural openings for windows are set out with jamb studs, lintel tracks and cill tracks to a design specific to Albion Sections in‐house engineered design. This provides a fully plumb external face for the finishes that are required for all the main types of cladding: timber, metal rainscreen, insulated render systems, facing brick, high pressure laminate boards and others. External Walling – Continuous System Continuous SFS (sometimes referred to as ‘oversail’ or ‘cantilever’) means the SFS wall is set outside the line of the primary structure to provide a fully continuous wall to the building. The base of the SFS wall is typically connected to the primary structure with either dead load brackets or shelf angles face fixed to the slab edge. ‘Restraint’ cleats or brackets are then fixed to every intermediate slab/edge beam to restrain the SFS. The cleats have vertical slots to allow any deflection of the floor to be accommodated without the risk of disrupting the SFS and its interfacing products. The main advantages of this system are the reduction of movement joints in the external finishes, the ability for an installer to install two storeys at once and the quality benefits of a truly plumb external wall. High Bay Walling High bay walling is generally an internal application most commonly used in distribution centres and commercial units where high internal partitions are required. Where traditional light gauge drylining studs fail, the Albion Sections SFS system is used to achieve high spans and is designed and supplied in a similar manner to the Infill SFS System. Load Bearing Structures Load bearing structures are when the Albion SFS Systems are typically used (either in panel or ‘stick’ form) to create whole or part buildings. It is suitable for low rise residential units as well as medium rise residential and commercial applications such as hotels. A highly flexible and robust method of building, the system consists of wall, floor and roof panels that are easy to manoeuvre and quick to install. Load bearing structures are not covered by this guide. Please contact Albion Sections Ltd for more information on Load bearing product and design support. Advantages of light steel frames are:
1 Rapid supply and construction times 2 Installation in any weather conditions without affecting the integrity of the system 3 Creation of dimensionally stable and accurate substrate for finishes that makes a building rapidly
weather tight 4 100% recyclable material with a high recycled content that is light weight and durable
