Maintenance

In order to maintain the durability of the products, it is convenient, at least once a year, a professional surface cleaning to keep it clean and in  perfect conditions.

Dirty particles and/or other typologies on the product when located in aggressive weather conditions, can easily damage the final finish over the years, if a periodic cleaning maintenance has not been carried out.

It is recommended for all Products lines not to use abrasive cleaners because these can change the appearance of the finishing touch.

Especially on smooth surfaces for DESIGN+ANTIGRAFFITI, a humid cloth with solvent is recommended for anti-graffiti, rubbing until everything is removed. The remaining dirt should be removed with a clean cloth. Repeat this if necessary

Technical conditions for a correct bending

  • According to the Technical Datasheet of the products, and according to the Norm ISO 1519, the mandrel used should have a diameter of at least 5mm.
  • The bending is performed at temperatures above 20º and keeping the protective film on.
  • The sheets must be stored indoors.
  • A piece of canvas can be putted on the outside of the bending, to make easier the operation and not damage the coating of the sheet.
  • Respect curvature’s radius. Depending on the thickness of the sheet and other parameters, it must be determined by the manufacturer of the Press brake and a qualified operator.

Cuts – Perforations – Machining

It is necessary to protect cuts, possible perforations and/or machining in outdoor environments, in case of this has been carried out.
Very aggressive atmospheres can cause  galvanic corrosion of the material, starting from the sides of the sheet.

Prevention of Galvanic Corrosion in Fixings

The contact, aluminum-stainless Steel is perfectly suitable in environmentally friendly atmospheres (rural or urban); however, in more aggressive atmospheres like close to the ocean or in industrial atmospheres, some preventive measures need to be taken to avoid galvanic corrosions. Rules and recommendations mentioned below  are general information, however, each project requires a private and preliminary study.

1.- Choose the closest metal combination to aluminum in the galvanic range, and for the aggressive environment chosen.
2.- When carrying out the merge of various metals, it must be considered in the design process that the “most resistant” surface of the metal to corrosion has a smaller surface than the “less resistant” metal.
3.- Isolate electrically the different metals to be joined by using washers and insulating joints (plastic or  neoprene), or with suitable paints.
4.-If possible, make the galvanic contact in the less aggressive areas,  in the anchor unit.
