RE: Steel Building Evaluation (after a fire)

[Subject Prev][Subject Next][Thread Prev][Thread Next]
British Steel also do a free publication 'Fire Resistance of Steel
Framed Buildings' which covers the re-use of damaged steel. A copy can
be obtained from them. Also see their web site www.britishsteel.co.uk
