What is SFS?
SFS is a component supply, structural, stud façade system which is extremely versatile and can be used to provide solutions to many different types of building construction, from external wall infill panels to internal high bay separating walls and continuous super structure solutions.
SFS has risen in demand over the last few years as it is a fast, economic, accurate and high quality method of construction.
Some well-known advantages of SFS is speed, lightweight and quality which lead to supplementary advantages, such as early completion, fewer snags, and minimal rework. However there is also many other advantages, including:
High levels of thermal installation and air-tightness.
The light-weight attribute of these construction systems means that foundation loads and sizes are significantly reduced relative to concrete and masonry construction.
Productivity and speed of construction is increased considerably which reduces site impacts.
Embodied carbon in the building fabric will also be reduced when using light steel framing and modular construction.
Light steel structures can be modified and extended easily. Modular units can be dis-assembled and re-used.
Maintenance cost of a steel structure is very high. Due to action of rust in steel, expensive paints are required to renew time to time. So that resistance against severe conditions increases.
Steel has very small resistance against fire as compared to concrete. Almost from 600-700C half of steel strength reduced.
Steel cannot be mold in any direction you want. It can only be used in forms in which sections originally exists.
If steel loses its ductility property, than chances of brittle fractures increase.
If there are very large variations in tensile strength than this lead steel to more tension. Due to which steel tensile properties graph falls down.
