High Bay Walling Solutions

The voestalpine Metsec SFS high bay walling is lightweight separating walls up to 20m high, used internally to provide high separating walls for factory units or atriums.

Overview of High Bay Walling Systems

High bay walls are a high performance SFS system single span internal walling system used to provide high separating walls for factory units or atriums. As they are often constructed within hot rolled steel portal frames, the amount of primary frame deflection that needs to be accommodated can be much greater than required for infill panels.

voestalpine Metsec SFS high-bay walls can be constructed up to 20m high and because of their lightweight construction there is rarely any need to provide additional foundations underneath the wall. The high strength to weight ratio of the voestalpine Metsec studs enables these high separating walls to be constructed without any need for any hot rolled steel wind posts which would be necessary in an equivalent wall of masonry construction. Walls can also be designed to meet project specific acoustic and fire rating requirements.

Sections Explained

voestalpine Metsec high bay 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 – 210M12-50

210 – Refers to the section depth of 210mm (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 – 214M12-70

214 – Refers to the section depth of 214mm (numbers ending in 4 or 6 are always un-lipped)
M – Refers to Metsec SFS
12 – Refers to the gauge (thickness) of the section i.e. 12 is 1.2mm 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. 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 lett ers 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.
