System of side walls

The side walls are made up of corrugated metal panels. The materials used in making the roof can be:

  • Type 1

    Sandwich panel with interior insulation of pre-lacquered polyurethane foam on both sides.
  • Type 2

    Sandwich panel with interior insulation of pre-lacquered polystyrene foam on both sides.
  • Type 3

    “In situ” sandwich made up of self-supporting sheet metal externally covered in galvanised pre-lacquered steel, insulation of light fibreglass wool 80 mm thick (M0), and self-supporting sheet metal with an interior covering of galvanised pre-lacquered steel.
  • Type 4

    Galvanised pre-lacquered sheet metal defined according to your requirements.
  • Type 5

    Galvanised sheet metal defined according to your requirements.

Pre-lacquered sheet metal

This is the final result of a long process in which, using rolls of galvanised sheet metal, they go through the following stages:

The material is washed under pressure with an alkaline detergent to remove oils, incrustations and other waste.


Application of a “Bonderite” layer.

The sheet metal with its Bonderite covering is washed in a solution of chromic acid to neutralise and remove chemical waste.

The bonderised material receives is washed again and then dried.

A layer of paint is applied to the external face of the sheet metal.

The layer of paint is dried in the oven.

A final, 25-micron layer of finish is applied to the exterior and 5 microns to the interior of the sheet metal.

Final drying process.

This way, the rolls of galvanised sheet metal are transformed into rolls of sheet metal pre-lacquered on both sides, which are then cold-worked and cut into the final panels.

This treatment gives the pre-lacquered panels special properties to resist corrosion, salt and humidity. At the same time, it ensures adhesion, uniformity of thickness and flexibility of the paint impossible to achieve with any other process.

  • Galvanised sheet metal

    This is one of the most common materials, up to now, in metal enclosures. Although of lower quality than pre-lacquered sheet metal, galvanised metal resists normal atmospheric conditions perfectly.


    Translucent panels on side walls

    The translucent panels can be combined with the metal panels vertically or longitudinally.

    The translucent panels have the same configuration as the metal ones so they overlap each other perfectly.

    They are made from polyester reinforced with 600 gr/m2 of fibreglass, and are indeformable by heat (see features).

  • Positioning of panels

    The panels’ first point of union to the structure is made at the base corner located immediately after the foundations. The following unions are made to the side purlins by means of Z or C profiles. This system can vary slightly when starting from a perimeter wall in civil works.

    The most important of these unions from the point of view of waterproofing is the one on the base. TEKTON pays special attention to this closure, bolting a metal plaque to the base corner and a foam barrier that has the same undulation as the panels.

    The metal panels are cut at the longitude corresponding to the height of the industrial building, which is why, vertically, there is no overlap between panels panel but rather they form a single piece in buildings of less than 12 m. in height.

    The types of bolts used in the joints are the ones described previously when speaking about the union of roof panels.
