Common steel section sizes ( metric ). |
|
The steel sections below
are a few of the common sizes you should be able to
order from any steel merchant. These tables are to assist
you when planning a new project, its always handy to
know what steel sizes are available. Sorry, but these
figures are in metric.
When you order steel, it pays to ask
the merchant what the standard length is and buy your
steel based on this length. Merchants dont like keeping
offcuts, so if you can order full lengths you could
get a better price.
