Galvanised steel is a durable and reliable material that has been used for roofing and wall flashings for over a century. It is made of high quality hot dipped zinc coated steel, with no additional coatings added. Galvanised steel now serves as the most popular base material for Polyester paint and PVC Plastisol coated flashings. When installed and maintained correctly, galvanised flashings can last for a number of years. However, it's important to note that the material is highly vulnerable to corrosion, particularly the steel beneath the zinc coating. For this reason, we advise against using galvanised flashings within three miles of the coast as coastal environments can significantly reduce their lifespan. It is important to keep in mind that galvanised steel will naturally weather and dull down over time. Additionally, the finish of galvanised steel can vary, so if color consistency is a concern, we strongly advise opting for a coated finish such as PCV Plastisol. Notes: It's not uncommon for galvanised steel to be mistaken for stainless steel, but it's important to understand that these are two distinct finishes. Please be aware that galvanised steel cannot be painted until it has weathered, which typically takes around six to twelve months. If you require a durable colored finish, we suggest considering polyester painted or PVC plastisol coated steel. It's important to keep in mind that galvanised steel is not a colour and its surface finish is not uniform. As the steel weathers, you may notice discoloration in certain areas, and the surface will become rougher over time. For a more consistent finish, we recommend using a coated steel finish such as polyester paint or PVC plastisol. It's important to take proper care when storing galvanised flashings. We advise that they are stored indoors (or under cover) at a consistent temperature if possible. This is to prevent water ingress and minimise weathering while still stacked. Additionally, we recommend degreasing the steel to remove any excess rolling oil, as this may cause reactions when the steel begins to weather.
