Coatings for steelwork
If you can estimate the corrosion rate of a building’s steelwork and specify an appropriate and cost-effective protective coating system, you can maximise the performance of the building.

If you can estimate the corrosion rate of a building’s steelwork and specify an appropriate and cost-effective protective coating system, you can maximise the performance of the building.
Recent changes to Building Code clause B2 Durability and the issuing of a technical advisory note and model specifications have helped clarify the requirements for structural steel and commonly used coatings.
Most of the surfaces on homes and buildings are painted or protected by a surface coating. Getting the job done right in the first place and a little basic maintenance can add years to the life of an architectural or decorative paint system.
Whatever method you use for removing lead-based paint, always take some simple precautions to ensure the worksite remains safe.
Because there are so many variables, understanding the durability characteristics of different building materials involves complex science. For many years, BRANZ research has helped improve our knowledge, inform the New Zealand Building Code and ensure our buildings are more durable.
The durability requirement of a coating might appear quite simple on first glance but, in reality, it is a bit more complex.
