Continuous Walling Solutions

SFS Oversail Walling

Typically constructed from the outside of the building continuous walling oversails the edge of the primary structure with SFS studs being fixed via cleats maximising floor area. More information can be found in our SFS Specification Manual, which is able to download from our downloads centre.

Our universal cleats can be produced either 3mm or 6mm thick and 130mm or 190mm deep. The cleats are pre-punched with slots and holes to allow easy fixing to the primary structure and to the SFS studs.

The projecting cleat leg can vary from 100mm to 300mm in increments of 25mm. Slots allow the cleat to be used as a deflection cleat. Alternatively, the cleat can be fixed through the holes to act as a dead load cleat supporting the wall.

The return leg of the cleats are provided with both 9mm and 6mm holes. 9mm diameter holes allow the cleat to be fixed to concrete with 6mm concrete screw anchors, M8 resin bolts or to steel with M8 bolts. The 6mm diameter holes allow the cleat to be fixed to steel with 5.5 diameter tek screws.

Universal Cleats

A new range of voestalpine Metsec cleats used to provide support to continuous wall studs, with a unique pattern of pre-punched slots and holes which offer both deflection and solid fix.

Slotted Angle (SA1002)

The use of slotted angles is often advantageous where the SFS is offset from the primary structure frame by a distance which is too great for a universal cleat.

Oversail Walling Section References Explained

voestalpine Metsec continuous walling section references are designed to be easy to read and understand at a glance. Each section type is identified by a unique reference consisting of three numerical values separated by a letter or a dash.

Studs Sections (lipped sections)

Example stud reference – 240M12-50

  • 240 – Refers to the section depth of 240mm (numbers ending in 0 are always lipped)
  • M – Refers to Metsec SFS
  • 12 – Refers to the gauge (thickness) of the section i.e. 12 is 1.2mm thick
  • 50 – Refers to the width or section flange of 50mm

Track Sections (un-lipped sections)

Example stud reference – 244M20-70

  • 244 – Refers to the section depth of 244mm (numbers ending in 4 or 6 are always un-lipped)
  • M – Refers to Metsec SFS
  • 20 – Refers to the gauge (thickness) of the section i.e. 20 is 2.0mm thick
  • 70 – Refers to the width or section flange of 70mm

Colour Coding Explained

voestalpine Metsec prints stud or joist sections and track sections with references that are designed to be easy to read and understand at a glance. voestalpine Metsec prints the Metsec name down both flanges for the thinner thicknesses of section and these are colour coded as follows:

  • BLACK = 1.2mm or 1.3mm thickness
  • RED = 1.4mm thickness
  • GREEN = 1.6mm thickness
  • ORANGE = 1.8mm thickness
  • BLUE = 2.0mm thickness

On our drawings any sections greater than 2.0mm or that are made up of multiple sections are shown in yellow so they are highlighted on the drawings.

Slotted head track or sections thicker than 2.0mm are not colour coded but still have the “M” reference on the web.

All stud or joist sections and track sections have a string of numbers and letters printed down the back web along with our CE mark. One of the string of characters will start with a M and have two numbers alter it e.g. M12 or M20. This denotes the thickness of the section i.e. M12 = 1.2mm thick section.

Performance Data

Need for full system performance data

Coupled with the need for optimal performance, confidence in that performance is paramount and being able to have data available to support the whole system is an ever increasing requirement.

Making performance data accessible

See how our systems will perform in different applications with a full range of insulation and plaster boards. We give you access to a full suite of performance and testing data so you can be confident in your construction.

Fire performance data is available with all three major manufacturers of plasterboard – BG, Knauf & Siniat.

Fire performance solutions available with 2 types of sheathing board, RCM Y-Wall (Calcium Silicate) and Euroform Versaliner (MGO).

Performance data is available with 2 types of insulation, both can be used above 18m, Kingspan K15 and Rockwool Duoslab.

Tested both load bearing walls and also non-load bearing for infill solutions which are more economical.

We now have performance data for over 200 wall and floor solution combinations.

Full performance data

Each and every one of our systems is tested or assessed for fire safety by the UK’s leading independent centre – the BRE. We also calculate acoustic and thermal data for complete peace of mind.
