Can you drill into structural steelwork?

Structural steelwork can usually be drilled into as long as:

* the hole created is not in an area of high load, for example an area that can usually be drilled into is the central part of an I beam web, but not near the top or bottom of the web,

* the hole is kept small relative to the steel member, * and any protective coating (such as fire or corrosion protection) is either undamaged, or repaired. It is best to get an Engineer's opinion on the specific situation.
