In the case of aesthetic maintenance, all the above rules for the maintenance of aluminum hardware apply. The maintenance interval depends on the frequency of fence usage and whether they are interior or exterior fences.
Exterior fences are usually exposed to direct atmospheric influence and therefore the cleaning is somewhat more frequent. Fence cleaning is performed with a mild jet of water and simultaneous wiping with a soft cloth. It is not allowed to use sharp objects for cleaning which can damage the surface layer of aluminum construction.
For functional maintenance, it is necessary to check for the solidity of the fence on a monthly basis. If a minimal movement of the fence is noted, it is necessary to contact experts, in order to improve the safety of the fence. Avoid hanging on the fence when cleaning on higher altitudes.
