Good maintenance of coil coated steel extends its life and maintains the aesthetic quality. You can find also more information about the maintenance of coil coated steel in the brochure.
A number of diverse factors influences the contamination that is deposited on the coil coated steel and with it the degree to which the quality of the steel deteriorates. The most important factors are classified in the phase in which they occur: the design phase, the installation phase and the usage phase of a building. In the design phase, one thing to consider is the choice of the correct coating system, for which project-specific advice can best be requested. During the usage phase, drainage is for instance important, because the longer the steel remains wet, the greater the chance of it becoming dirty and corroded.
Washing the steel regularly ensures that the gloss, colour and technical properties are retained for longer. Often, cleaning is only considered after the first signs of the accumulation of dirt are seen. That is normally too late and leads to high costs for maintenance and cleaning.
As a result of the influence of the weather, dust, sand and even corrosive substances are deposited on the coating. After a period of time, the deposits become attached. If (planned) maintenance of the walls and roofs is started on time, simple and neutral cleaning agents are sufficient. If initial maintenance is delayed (too long), then often more aggressive cleaning agents are required.
There are various cleaning agents on the market that can be used for cleaning the sheet. Not every agent is suitable in every situation. Careful consideration is required. The frequency and time that you should clean the sheet (or have the sheet cleaned) depends on the degree of precipitation (natural washing) and the location of the building.
