Thread: Rust proofing steel lintels

You could use any type of metal primer,if the exposed surface is clean of scale,you could even put a coat of cold galvaniseing paint on it.

Thanks Pipeclay - noted. My initial concern is will there be, in the long run, any detrimental effects (ie corrosion) in the unexposed areas (including end cuts) if the installed lintel is raw. I suspect the Code requires corrosion-proofing must be applied all over irrespective of being concealed or exposed. BTW opening is between a bedroom and robe (ie not directly in a relatively high moisture area - unless Bride stops using exhaust fan in adjoining ensuite!).

What does your contract specify. It should be in the contract.

Hi GottaPlan,

Most lintels I've seen lately are galvanized... are you sure that yours are mild steel?

Have a read of this - Metwest Steel Pty Ltd :: BCA Changes to Corrosion Protection

Drive past any building site and you will see either hot dip galvanised or zinc silicate painted (or both) lintels dumped on the verge. My house, built in 1928, has neither. The steel arch bars, supporting the segmental brick arches over the windows, have nothing more than a coat of paint on the exposed underside. There is rust on some of them, but they will see me out.

not sure where goodwood is but in victoria lintels(bca)can be black(painted) up to a close distance to salwater,read up on the building code australia website.hot dip gal is superior but the heavy lintels such as t bars and channel beams etc can cost up to 70% more depending on your retailer.homes have been being built for decades with painted lintels and theydo the job verywell if salt water and spray are not present.

sorry,just read" interior opening" in your post.my thoughts are (i resell lintels and fabricate heavy lintels) that it is fine if you are not close to the ocean<500 metres.just check the dimensions and thickness he is useing.
