Structural Frames, beams and bridges are areas that are greatly exposed to weather and wind, making maintenance challenging. Here, SiOO:X Impregnation has great advantages with results showing up to 15 years of effective protection. With its eco-friendly composition, it is particularly appropriate for use in sensitive environments such as marine locations, near water courses, in wild life reserves and preservation areas. In conservation areas the natural grey colours compliment the material colours in townscapes and in the natural environment.

A dramatic and powerful illustration of the use of SiOO:X to protect and provide natural and attractive colouration on structural frameworks is the Auckland Tower, a part of the Auckland Project.
