guttering and fascia
Colorbond guttering became popular in Australia in the 1960s when it was introduced by the company BHP Steel (now BlueScope Steel). Colorbond is a brand of pre-painted steel that is highly durable, corrosion-resistant, and available in a wide range of colors and finishes. Its popularity grew rapidly due to its aesthetic appeal, long lifespan, and low maintenance requirements. Colorbond guttering quickly became a preferred choice for residential and commercial buildings in Australia and is now widely used in many other countries around the world.
