FAQs.

How long do utility marker posts last?

Steel posts typically need replacing within a few years due to rust. Timber posts rot and split just as fast. Identimark marker posts are built from sun-proof polymer, designed to last the life of the asset they mark. Every post is backed by a lifetime guarantee.

What colour marker posts are used for different utilities?

Colour conventions vary by state and provider. Common conventions are yellow for gas, blue for water, red or orange for electrical, and white or cream for telecommunications. Custom colours are available to match your requirements.

Can utility marker posts be custom printed?

Yes. Custom colours, logos, identifier text, route numbers, emergency contacts, and reflective treatments are all available. Posts are manufactured to your exact project requirements.

Why use polymer marker posts instead of timber or steel?

Polymer marker posts are impervious to rot, rust, termites, and sun damage, the failure modes that shorten the life of timber and steel. The smooth surface resists graffiti. Lightweight construction reduces transport and installation costs.

How do I order the right marker posts for my project?

Contact us with your project details. We will recommend colours, printing, heights, and reflective treatments based on your requirements. Everything is manufactured to your exact specification.
