At Spunlite’s in house coating facility in Christchurch our skilled painting staff handle all coating requirements to our robust Quality Assurance standards.
For above-ground coatings Spunlite use Altex Carboline coating systems, a recognised leader in the coating industry. With coatings from ISO Category C3 to C5, in any standard paint chart colour, we can provide a quality coating to suit your project requirements.
Spungard is our in-ground protective coating system. This is applied over the top of the galvanizing on the in-ground portion of the pole to provide extra protection against corrosion. For Spungard we use a specially formulated coating system from Wattyl Industrial Coatings. Spungard is compliant to Waka Kotahi NZTA Specification M26 and Auckland Transport Code of Practice (ATCOP) Chapter 19 Street Lighting
Spunlite partner with Valmont Coatings to ensure our poles are galvanized in compliance with relevant standard AS/NZS 4680:2006.
Valmont have been in the galvanizing industry for over 70 years, have more than 1200 employees and are leaders in the market worldwide.

|Description||This is on the shoreline of rough sea regions, with a constant smell of salt spray in the air with heavy salt deposits being present. This is generally less than 50m from the high water shoreline This category is also noted in heavy/aggressive industrial regions with acidic air environments. This category is divided into Marine and Industrial groups and may require specialised paint products and applications. Sea Shore (Surf)||This category occurs mainly on/near the coast line. In sheltered calm water areas this would extend to about 50m from the high water. In heavy surf areas this region would extend to 500m-1km inland. As with all categories the extent of the distance will depend on prevailing winds, wave action and topography. This area would have light salt deposits and will have a frequent smell of salt in the air. Some industrial areas could also fit into this group. Sea Shore (Calm)||The characteristics of this category are costal areas of low salinity with low salt deposits and only the occasional smell of salt in the air. This area will generally cover from 500m/1km to about 50km inland. Inland/Light Coastal|

|Micro Environments – In addition to the physical location of the painted product, a local micro climate can be created by surrounding structures / plantings need to be taken into consideration. The local micro climate conditions may require using a different ISO category. These conditions would include areas where the metal surface will stay damp/wet for extended periods of time, and unwashed surfaces that allow build up of contaminants (salt / pollution) and re protected from cleansing rain. Other effects that may affect the deterioration rate of the paint coating would include acidic (alkaline) fallout, industrial chemicals/solvents, airborne fertilizers/chemicals, prevailing winds transporting chemicals, excessive hot or cold temperatures and surfaces exposed to abrasion/impact. It is near impossible to predict the exact environment and some educated judgement in needed to asses the influences on coating life. Eastern coastal areas all be less aggressive than West coat area and can extend to the closer distances to the shoreline.|
