Steel Roof Flashing And Trims

Steel flashing and trims are the final step and finishing touch in completing your roofing or cladding project. The steel trim and flashing act as weatherproofing for the corners and ends of the building, protecting it from damaging rainwater, snow, wind, and ice. As standard, the metal cladding flashing is available in 3m lengths, but longer sizes are available on request.

You can order the metal edging trim at the same time as your corrugated roofing sheets or box profile roofing sheets and cladding to ensure consistent colour and a high-quality finish. The steel roof flashing is quick and easy to fit, providing years of protection with no maintenance.

All materials, unless specified, come with welted edges, also known as safety edges, which help with handling during unloading and fitting. They also add rigidness to the products. If not welted, when fitting the flashing, it can cause the steel to have a wave look and edges to be sharp.

Most of our metal trims and flashings are manufactured for our Plastisol range due to the durability and excellent aesthetic of the finish. All flashings are available in polyester and galvanized as well.


An alternative to using standard plastic rainwater goods is our Trimline Gutter. This product can be manufactured in the same colour or an alternative. It gives a sharp, easy-on-the-eye finish to the building. Please ask a staff member for details on this product as it can be manufactured to individual specification.
