This should be done 2 to 3 times a year depending on the aggressiveness of your environment. Make sure there is no water holding area and make sure the drain holes are unblocked.

"All of our products are high quality, long lasting CLASS II powder coated. To enjoy it as long as possible, we recommend that you clean your gate regularly!"


Long-term exposure to UV rays from the sun or moon, rain, pollution, splashes and various external attacks (defoamers, herbicides, etc.) can slightly alter the color of the powder coating. This discoloration does not affect the strength and mechanical properties of the product. To limit this phenomenon, regular washing of your gate is necessary.

Thermosetting paint

After assembly, welding and cleaning, our gates are subjected to a sandblasting process with silica sand and corundum, then they are washed.  and degreased with solvents and acids, dried in the oven, to be finally subjected to electrostatic application of polyurethane powders of the chosen color and placed in the oven at 200 ° for 20 minutes. All this process is done online, in order to guarantee a high quality of the product.




Maintenance for our painted products.

The architectural paints used in the system require regular maintenance and cleaning to ensure the continuity of the decorative and protective properties of the surface.

The frequency of cleaning depends on many factors, including:

1st Geographical location of the building

2nd  Environmental corrosivity class in which the construction is inserted, for example: marine, industrial, residential, rural, etc.

3rd  Level of polluting emissions into the air.

4th  Presence of winds with considerable intensity (eg Bora di Trieste) possibility of dust carried by the wind, eg. sand, dust, etc.

5th  Hypothesis of change over time of the corrosivity class (e.g. transition from rural to industrial)

The best cleaning method is through a regular washing of the surface, using a solution of warm water and mild detergent (pH 5-8). All surfaces must be cleaned using a soft cloth or sponge, do not use any brush if not of natural origin.

The frequency of cleaning depends on the appearance you want to maintain and the need to remove deposits that could, on prolonged contact, cause damage to the coating. In a not particularly aggressive environment (eg rural or urban), the normal cleaning frequency can be about 12 months.

In the presence of particularly dirty deposits, a greater cleaning frequency is recommended. When the environment is aggressive, the cleaning frequency should be reduced to 3-month intervals. In the presence of high air pollution or in the presence of a particularly corrosive environment, or in the presence of water with a lot of fixed residue,  the period between interventions should be further reduced.

It is absolutely forbidden to use solvents or solutions that contain: ester chlorinated hydrocarbons

acetones abrasive pastes



  • Urban - rural inspection and cleaning every 12 months

  • Industrial inspection and cleaning every 6 months

  • Marine inspection and cleaning every 3 months

  • Industrial and marine inspection and cleaning every 3 months



- If it is necessary to retouch the painted surface, we recommend the use of two-component polyurethane paints, to be applied according to the following cycle:

- Clean the surface with a mild solvent, applying it freely with a cloth, dry taking care to remove any residues.

- If necessary, even the surface by smoothing the part to be restored with abrasive paper (max grain 320) and then clean thoroughly with a dry cloth.

- Mix the paint vigorously for about 2 minutes.

- In case of spray paint (can), spray the color on a palette (even a sheet of cardboard can do the job) apply the paint with a brush (small size) and limit the application strictly to the part to be restored.
