Let's talk steel.

Here I'd like to talk about hot dip galvanising compared to DuraGal. It’s a big issue, there’s lots of marketing out there for DuraGal, and it's a popular product. So, what's the difference?

Nice fresh hot-dipped galvanised steel columns for 25 and 27 Chapman Place.

This little pile of steel will hold up two houses... and cost over $12 000.

A few minutes on Google will find you specification information and some revealing case-studies about the differences between hot-dipped and DuraGal if you're interested.

Hot-dipped galvanised columns are made like this: the anti-corrosive galvanised coating is applied after your columns have been fabricated, and it's applied by dipping the whole piece into the galvanising solution, covering every surface, every weld, even the inside of columns through the holes specially left for this purpose.

Here you can see the hot-dipped galvanised coating has completely enveloped every weld and hole of the column components.

I have designed these houses at 25 and 27 Chapman Place for the lowest long term maintenance cost, and that's why I'm using hot dip galvanised columns, as it offers the longest corrosion protection. The catch? It’s twice the price of DuraGal and can take an extra two weeks from ordering - which are the main reasons that others might not use it.
