There have been some big investments made in the various large structures around New Zealand. Quality protective coating work on these assets ensures these investments are safeguarded through the decades to come.

At National Group we ensure critical infrastructure is kept rust-free and looking its best. Our teams are well versed in waterproofing and corrosion protection on a wide range of structures – everything from chairlift towers to flour silos to container cranes. 

With a wide range of industry-leading coating brands to choose from and the advanced equipment to ensure everything is covered correctly. As importantly, dedicated National Group team members undertake all work. We don’t sub-contract and we don’t cut corners.  

Our teams are regularly called on to ensure no rust appears and, if it does, that it is treated and dispatched quickly and efficiently. Be it wet or dry sandblasting or, for food grade areas, dry ice blasting, we remove the rust and protect the structure.  

Be it cranes, tanks, silos, food grade areas (for large food manufacturing sites), steel beams, bridges, transmission towers, wind turbines, power stations, penstocks, carparks or any other challenging steel structures, we’ll get the job done right, first time and every time.
