Recommended environment for installation and storage
Recommendation for installation of FLEXNET wire cable trays system, considering the infl uence of outer environ ment divided according to the IEC364-3 and Czech standard CSN EN332000-3: It is not recommended to install the system in industrial premises with heavy mechanical stress - intensive impacts and vi bra tions (AG3, AF3). The system is fully suitable for installation in industrial premises with a medium and slight mechanical stress.
ZZ - Heat zinc coated surface, coat min.120µm
The system is suitable both for indoor and outdoor installations of all temperature and humidity (AB1-AB8). The system may be installed even in premises with increased probability of water presence - places where water can spring in all di rec tions (AD1-AD5). Installation is not recommended in places with regular water occurrence like sea moles, and in places partially or permanently fl ooded (AD6-AD8). From the point of view of corrosive substances in flu ence, the system may be in stalled in AF1-AF2 environment, i.e. environment with a signifi cant presence of such sub stanc es. Coastal areas and places with sig nifi cant ly polluted at mos phere are involved such as neighbourhood of chem i cal factories and cement mills.
GZ - Electroplated surface, coat min.10µm
The system is suitable for indoor installations in a dry environment (also stored in a dry environment). The system is suitable for outer instal la tions only if protected against atmospheric infl uences (AB1-AB7). Installation in unprotected outer environment is not recommended (AB8).
From the point of view of corrosive substances, the system may be installed in AF1 environment, i.e. environment with a minimal infl uence of such substances. The system should not be installed in highly polluted areas like in chemical industry, etc. (AF2-AF4).
|Countryside environment||0,8-1 µm/year|
|City environment||1,5-3,5 µm/year|
|Sea environment||2-5 µm/year|
- When you use wire cable trays with heat-zinc coating in a city environment, your installations is protected against corrosion more than 17 years.
(Zinc loss is 3,5 µm/per year)
