Metsec SFS is our market-leading light gauge, galvanised steel structural infill framing solution for general external wall and high rise construction projects.
As one of the leading products on the market, it offers a range of benefits – it’s cost efficient, it supports sustainable construction and it offers leading acoustic, thermal and fire performance.
But we wanted to put it to the test. So we commissioned an independent report to prove that it’s as good as we say it is.
We considered four comparative façade scenarios fixed to the SFS inner leaf, based on a building model of a reinforced concrete framed residential development requiring 4,000m2 of cladding.
We compared all areas of the build scenarios including:
For each of these scenarios, we compared an inner blockwork wall with SFS.
The results were clear. In comparison to an equivalent blockwork build, SFS proved to be quicker to build, to increase sustainability performance and to significantly improve cost efficiency.
We've split the results into three sections: project benefits, cost efficiency, sustainability.
Precision, practicality and performance.
SFS steel is delivered to site on flat bed trucks, ready for a crane off-load directly to the loading bays on the building scaffold at each floor level. It is usually then installed from the inside of the building using a scissor lift or cherry picker platform.
In this methodology, SFS typically required 2 lorry loads of SFS; the blockwork required up to 50.
SFS positively affects traffic and health and safety management.
Less deliveries means less environmental impact.
A cost-efficient solution.
SFS offers significant cost savings in every scenario we tested. The figures below show both the like for like material comparison, and an overall build cost comparison.
SFS embodies less carbon and creates less wastage than traditional blockwork construction.
SFS can be supplied cut to length and offcuts can re-enter the resource lifecycle - rather than being discarded as waste.
It has a wastage rate of 1%, as opposed to the 20% wastage rate of dense concrete blockwork. As a result it created less waste in each of the four scenarios we tested.
