Height |
 The maximum height
of a road truck is 4.5m, so there is usually no point in higher doors
(except waste transfer buildings, aggregate stores and the like which
need to cater for tipping trucks up to 11m high - and of course Aircraft
Hangars). Fork lift truck masts may be higher, dictating a 6m eaves
height. 5.6m is the minimum height in which 2 storeys of office can
reasonably be built.If your operation needs
less height, say manual assembly, restrict the height to 3m, or you will
have bigger heating or cooling bills; use 2 floors or more floors to
allow truck entry/exit.
If you need cranes, tell us the hook height. Tell
us of any specific internal height requirements, so we can make sure our
steel is out of your way.
Please do not forget the resale value of your
building if you should relocate and wish to sell it: 5.6m to eaves may
be the optimum height.

Length |
 Any length is
possible, up to 1km or so. Unless there is a specific requirement, let
us optimise the frame spacing for the required length. |
|
|
Width |
We can do any
clear span up to, reasonably, about 200m! The most economic spans, for
the building costs in isolation, are about 15 to 20m. At 30m the cost is
creeping up, and it continues to rise as the span increases.

Large clear span (no
props) |

Factory with 2 rows
of props |
|
A row of props at the centre, or 2, or 3 rows may
save structural cost. But please think of your operation first. The
savings may seem worthwhile as a proportion of the steel, but will
vanish if you ever drive a truck into a column, or jeopardise the
planning of a production line because of an internal column. No one has
ever hit a column that wasn't there. No one has ever cursed because the
span of a building is too big. Let REIDsteel advise you on possible
spans and the impact on costs.

Suspended Floors |
 Economy is usually
around 5.8m × 5.8m column spans. But all other spans are feasible. The
price starts to rise above 7m spans in either direction. |

|
Shipping |
| Please remember a
20' container holds steel 5.8m long, and a 40' container 11.9m long.
Every time you ask for 6m bays, 6m to eaves, 20' length, you are putting
your cost up if it is to go by container. Similarly a 23m span overall
can divide into 2 rafters that will fit a 40' container. 24m span wont
fit and you will pay for extra freight and extra splices. |
