Weather Resistant Signage

Well….we survived Ali,……now bring on Bronagh, Callum, Deirdre, Erik, Freya, Gareth, Hannah, Idris, Jane, Kevin, Lily, Max, Niamh, Oliver, Peggy, Ross, Saoirse, Tristan, Violet, Wyn…..or whatever names the Met Office throw at our weather resistant signage!

NovaDura signage is ideal for all coastal locations exposed to the elements.

Primarily it is resistant to salt spray, that even can affect signage in long inland estuaries where salt air can travel on the wind. However there’s no real definitive answer as to how far salt air travels. If you take a look around inland from the coast you’re likely to see evidence of salt deposition on cars, window sills, and shop fronts. Consequently they will all be suspect to corrosion.

Rates of corrosion will vary in different areas due to factors such as wind speed and direction and the coastal topography. Studies show that salty air and the effects of corrosion can be seen up to 50 miles in land. On the contrary, when travelling inland the salt factor diminishes then industrial and urban pollutants such as SO2 can take effect.

Marine environment

Fortunately, with our choice material of aluminium that has excellent corrosion resistant properties. For that reason, it’s no coincidence that the marine industry use a lot of aluminium in the construction. If the bare metal does become exposed it can ‘begin to corrode’. However the thin coating of aluminum oxide that forms as a result creates a protective shield that inhibits further corrosion.

With our tough durable stove finished powder coating process, instances of breaching through to bare metal are rare. Consequently that is why our primaDURA is the choice of many for seafront weather resistant signage in the UK.

We’ve also added ‘Depth Gauge’ boards to our range in both standard Class D photoluminescent finishes. When fully charged by natural daylight, permits visibility at night or dusk conditions.

NovaDura signage is proven to withstand atmospheric effects. Likewise the coatings have been tested and approved to the following standards:

HumidityBS 3900-F2:1973Pass 1000 hours – no blistering
Sulphur DioxideISO3231 (Kesternich Test)Pass 24 cycles – no blistering, creep < 1mm from scribe
Boiling water – PermeabilityEN12206-1: 2004 Part 5, 10Pass – no defects after 2 hours
Mortar ResistanceEN 12206-1; 2004 Part 5, 9No effect after 24 hours
Salt FogISO 7273 (500 hours)Max. 2mm creep from scratch
Natural WeatheringISO 2810 (Florida 12 months 5º south)>50% Gloss retention after 1000 hours
*Accelerated WeatheringISO11341>50% Gloss retention after 1000 hours
ASTM G154 QUV & ISO11507> 80% Gloss retention after 500 hours
QUV B313>50% Gloss retention after 300 hours
