COMPARE THE ADVANTAGES COMPARE THE COSTS
Steel decking is cheaper to install than reinforced concrete.
The significant savings on site from using steel deck
outweigh the initial cost savings of buying reinforced
concrete.
The reason behind the savings is the speed and ease of
installing steel decking compared with pre-cast concrete
slabs. This means that buildings can be erected faster,
enabling projects to be completed earlier and within budget
without compromising on quality.
How much time can you save by using steel floor deck?
7.5% FASTER
Industry research carried out by British Steel Advisory
Service into construction times for composite steel decking
compared with reinforced concrete shows that, construction
spread nationally, teams can save 7.5% on overall construction
times.

How much lighter is steel floor deck? 12.3% LIGHTER
Steel decking averages out to be 12.3% lighter than concrete
floors for similar buildings. Foundation and structural
cost are reduced due to shallow floor zones and lighter
weight of steel floors.

|
BENEFITS |
| Ease of installation |
|
Quicker project time, saving on crane time and
site costs |
| Steel floor deck provides a stable working platform
instantly |
|
Complies with CDM regulations. Enables crews to
work underneath at an earlier stage |
| Steel floor deck arrives on site in lightweight
sheets, cut to length |
|
Reduces cranage cost. Decking can be manhandled,
saving installation time |
| Easy to fix using studs, clips and screws |
|
Minimises installation time |
| Pumping concrete as opposed to pre-cast units |
|
Saves cranage time and minimises installation
time |
| When installed the deck acts as a diaphragm |
|
Adds stability to the support structure |
| Thinner, lighter slabs. |
|
Overall ceiling and floor zone. Outer façade
is reduced, a particular cost advantage in multi-storey buildings.
