Recommended means of transport for sandwich panels:

• A truck (tractor + semi-trailer with a length not shorter than the length of the loaded panels) with an open semi-trailer or one enabling side loading on both sides along its entire length
• The weight of the load cannot exceed the permissible load capacity of the set,
• Transport belts should be placed on the load at a distance of max. every 3 m, but not less than 2 belts per package – the tension of the belts must not cause deformation of the boards.

Sandwich panels should be stored in packages (posts), a maximum of two packages can be stored on top of each other.
The table below shows the max. number of boards that can be arranged in one package.

• It is recommended to store the boards on a flat surface (square, hall) on joists or polystyrene sleepers, which must be spaced a maximum of 2.5 m apart (for boards with a total length of up to 2.5 m, at least 3 sleepers should be used).
• It is allowed to store a maximum of two board packages up to 6 meters in size, one on top of the other; in the case of board packages above 1 meter, they should be stored individually. All board packages must be stored on a level surface with the ability to drain water.
• When storing boards at the construction site, they should be protected against mechanical damage, exposure to UV rays, aggressive environments (acids, fertilizers, salts and other corrosive factors), precipitation, strong wind and others.
• It is recommended to store packages under a roof in ventilated rooms
  The boards should be stored on an even surface (square, hall) on joists, polystyrene or wooden sleepers, which must be spaced a maximum of every 2.5 m (for boards with a total length of up to 2.5 m, at least 3 sleepers should be used ).
• Protective foils are used to additionally protect the board surface against mechanical damage, stresses and impacts that may occur during transport or reloading. Foils never relieve you of the obligation to properly protect the boards during storage.
• It is recommended to remove the protective foil before mounting the elements on the facade or roof of the building. Removing the foil should be done at positive air temperatures, because at negative temperatures the adhesive delaminates and some of its components may remain on the sheet.
• Improper storage of sheets may make it difficult to remove the protective foil and leave traces of glue on the surface of the sheets. In such cases, complaints about adhesive residues left by the protective foil will not be accepted by the Manufacturer.
• In the case of boards with hidden fastening, make sure that the foil is removed from the inside of the longer lock before installation.

  ATTENTION !!!

  In the case of wall panels with visible fastening, the upper side of the panels in the package is the façade side, which should be paid special attention!

In order to extend the durability of roofs and facades made of coated sheet metal, they should be regularly inspected and maintained.

• Inspection – Once a year (preferably in spring), the roof/facade should be inspected to detect any damage early.
• Cleaning sheet metal – Roofs/facades made of coated sheet metal require cleaning at least once a year. Dirt settling on the sheet metal may cause uneven discoloration of the color (the result of uneven exposure to UV rays), as well as reduce corrosion resistance (dirt retains moisture on the sheet metal, gradually damaging it). Dirty and stained places can be cleaned with a soft brush and water (max. temperature 60°C). If necessary, a mild detergent can be added to the water (pH 6÷7, max. 10% solution). Pressurized water (max. 100 bar) can also be used for cleaning, however, the water jet cannot be used too close to the surface of the board (min. 30 cm) and cannot be directed perpendicular to the surface. At the connectors, the water stream should be directed downwards to avoid pressurized water from entering the gaps around the connectors. Old board coatings should be handled with extreme caution. Washing should be carried out from top to bottom and the cleaned area should always be thoroughly rinsed immediately with clean water.
• Do not use scouring powders, nitro solvents, chlorine solutions, aromatic agents, as well as agents containing salmiak (ammonium chloride) or sodium salts.
• Damage – Possible damage during the warranty period must be consulted with the roof/facade Contractor and may only be performed with his written consent. Damage to small surfaces can be repaired using air-drying repair varnishes, while painting large surfaces is generally only possible using special industrial paints adapted to the renovation of coverings. The surface to be painted should be limited only to places requiring it (scratches to the metal layer, corrosion spots, etc.). Preparation of the surface for painting should be carried out according to generally accepted rules. Always carefully remove all traces of corrosion – preferably using special brushes or fine-grained sandpaper. Then the repaired surface must be thoroughly dusted, degreased and cleaned. To degrease the surface, you can use extraction gasoline or water with surfactants (preferably with the addition of 1-2% ammonia solution). The repaired zones may show differences in color compared to the original colors of the sheet metal due to the natural impact of atmospheric phenomena (aging of the varnish under the influence of UV radiation).
• ATTENTION – During inspection, cleaning, maintenance and repairs, health and safety rules must be strictly observed.
