On the surface, it may seem as if using non-galvanised steel may be cheaper. The contractor may even assure you that giving the trellis a coat of paint will prevent any rust from forming.

But scratch a little beneath the surface and you’ll see why this treatment doesn’t hold water.

While installing trellises outdoors, there’s a definite chance that it could rain and the trellis could get wet before the installation is complete. Water seeps everywhere and “attacks” non-galvanised steel instantly. Within days, you could be looking at some very rusty metal.

The contractor would have to do some serious work in sanding the rust off every nook and cranny before painting a layer of primer, and the paint. If this process is not done well, you could be looking at some rusty, expensive structure in a few months’ time. Maintaining a rusty trellis is much more costly than one that is done well, and virtually needs no maintenance.

The Absolut Outdoors Way We use hot-dip Galvanised Steel in our trellis installations. This means that all surfaces, including the internal walls of pipes or hollow metal bars are covered with a layer of zinc that reacts with the steel to make it tough and resist mechanical damages during transport or installation. While installing the trellis or pergola for customers, we are not worried of any sudden downpour damaging the customer’s trellis even before it’s used. We believe this reliable and value-for-money approach is the only way to ensure lower costs for our customers in the long term. Because once your trellis and pergola is installed, you’ll want to be pondering the themes of parties you’ll be throwing and not worry about maintaining it.
