Browse Forums General Discussion 1 Dec 29, 2013 6:53 pm I hoping someone could help me... I'm in the process of re-erecting an original Nissen Hut ( http://www.nissens.co.uk/Working%20Drawings.htm ) on a block of land down on the Victorian coastline. The frame of the hut is made of 45 x 45 x 4mm curved rolled steel. Each hoop is 3 pieces of steel bolted together to make the semi circle. The steel is quite old and has a minor surface rust but is structurally sound. What I'm wondering is if I need to treat the steel before it's erected with any kind of rust protector seeing as it's going to be in a coastal environment. If so, what do people recommend? The frame will be covered by the colorbond outer layer of sheeting when it's complete. Any suggestions would be more than welcome. Many thanks. BH Re: Steel frame protecting from salty air 2Dec 29, 2013 9:29 pm I think definitely so. The best would be to have the steel galvanized, but I suspect that would be prohibitively expensive. Next best would be to lightly sandblast it, either by getting someone to come in with a machine, or buying one of these then reselling it: http://www.ebay.com.au/itm/38-Litre-10- ... 71e&_uhb=1 then etch passivate the surfaces with a coat of 1/10 phosphoric acid or proprietary rust converter, rinse this off, allow to dry, and then prime with a zinc rich type, like http://www.duluxprotectivecoatings.com. ... _pc102.pdf by either spray or brush, then finish with at least 2 salt resistant topcoats that have the right Nissan hut look to it, like http://www.duluxprotectivecoatings.com. ... _pc652.pdf If you don't feel like sandblasting the frames, you could substitute a power wire brush. I don't have a connection with Dulux, any top brand will have stuff like this. Re: Steel frame protecting from salty air 3Jan 09, 2014 9:05 am I've read in this article that according to Australian Building Code there is a minimum requirement for exposed steel near the coastline, might be worth a read and then further investigation - http://www.desudesignerhomes.com.au/timber-or-steel/ Re: Steel frame protecting from salty air 4Sep 30, 2014 11:13 pm +1 Hot Dipped Galv and later painted.
