Spouting
IMPORTANT: BRANZ Appraisal applies to the fascia system ONLY and does not include the spouting.
Rainwater System
Bildon 2000 spouting profiles are firstly roll formed using .55gauge galvanised, pre primed steel. Once roll formed the powder coated surface is applied. This ensures that no stretching or micro cracking of the powder coated surface occurs, thereby giving optimum protection and durability. All cut ends of the spouting are sealed using an etched primer and finished with a matching top coat.
If spouting is to be fitted to buildings within 100 metres of the sea we recommend the use of alternate materials for your spouting system, such as copper, stainless steel or PVC. We are also able to supply a range of profiles using the colour steel range of spouting profiles.
Spouting Care and Maintenance
If you have chosen our .55 gauge powder coated spouting system we recommend regular washing with a soft brush and warm soapy water and then a light hose down to remove any soap residue. Maintenance should be undertaken at least 2-3 times a year, monthly if you live in a salt spray environment. This will improve the longevity of the powder coated surface. Additionally, routinely check that your spouting is free of leaves and debris and hose down the internal area of the spouting. Failure to carry out regular maintenance may invalidate any warranties offered or implied. Water blasting of the powder-coated surface should not be carried out under any circumstances.
Corrosive Environments
In corrosive environments such as coastal areas, areas of localised geothermal activity and corrosive industrial environments the stainless steel fascia and bargeboard brackets must be used. In other areas the galvanised steel fascia and gable brackets may be used.
Coastal Areas (Sea Spray Zone)
For the purpose of determining whether you are in a coastal area we use the NZS 3604:1999 definition for the Sea Spray Zone. This is given in Clause 4.2.3 of this standard as follows: 'within 500 metres of the sea including harbours, or 100 metres from tidal estuaries and sheltered inlets, as well as areas shown in white in Figure 4.1 on NZS 3604. The Sea Spray Zone also includes all offshore islands including Waiheke, Great Barrier, Stewart, and the Chatham Islands'. The white areas of the corrosion zone map shown in Figure 4.1 of NZS 3604 mainly affect the following areas: The west coast of the South Island (including a good part of Fiordland); the west coast of the North Island above Auckland; the Far North (above Kaitaia); an area around Bluff; an area around Dunedin and parts of the Marlborough Sounds.

Geothermal Activity Areas
These are mainly found in the area that extends from Ohakune to Te Puke but they may occur elsewhere. Advise regarding the location of these can be obtained from the local territorial authority.
Corrosive Industrial Areas
Advise regarding the location of these areas can be obtained from the local territorial authority.
