There are several finishes for stainless steel. The most popular are matt satin finish, satin, tinned and shiny finish.

The matt satin finish is raw stainless steel, treated to reduce its natural shine. However, its surface will keep some subtle reflections that will give the panelling life and movement. The satin finish is a similar treatment although more subtle, leaving more reflections and a flatter texture.

The tinned finish is the shiniest at first although over time this shine is completely lost and ends up entirely matt. It is the most recommended for renewing old metal roofs, simulating lead, or for new buildings with more traditional architecture or simply where a matt finish is preferred.

The shiny finish brings out all the brightness of stainless steel. One good example is the San Pedro Hospital in Logroño where Quinta Metálica has installed a 'polished mirror' stainless steel facade in a system of folded panels, transforming the facade into a reflection of the colours and lights of the Rioja sky and the park that borders the building.

Apart from these more typical finishes, there are many other finishes providing really amazing aesthetic possibilities. Textured, coloured and polished finishes give us endless appearance for this material.

Stainless steel has several qualities that make it particularly appropriate for panelling roofs and facades:

  • Excellent resistance to corrosion and very long-lasting. It is estimated to last over 100 years in all atmospheres (with the right alloy - see below).
  • It does not require any maintenance or cleaning
  • It is malleable
  • 100% recyclable with no limit to the number of recycling times; it is not toxic and there are plenty of resources
  • It is very easy to weld, although it is very important to use the correct filling metal and stripper
  • It is compatible with other metals usually used in building, such as steel, aluminium and zinc

However, we have to pay attention to the following aspects:

  • It is important to make sure that we are using the right alloy. The EN 14307 alloy (AISI 304L) is suitable for inland areas of the Peninsular that are not excessively polluted. The EN 14404 (AISI 316L) alloy is recommended for coastal areas and areas close to industrial centres. For material that would be directly soaked by sea water or in areas that are highly polluted, please consult Quinta Metálica.

Stainless steel can be used in the following systems of ours:

  • Seam (roof and facade)
  • Bar joint
  • Butt joint (scales)
  • Facade panels
  • Cassette panels

The following materials can be used as a direct support:

  • Water-repellent board, 19 mm thick
  • Rigid insulation
  • Plywood board
  • Corrugated metal
  • Masonry on facades whenever this is flat and smooth
