Recommended modes of transportation for sandwich panels:

• a truck (tractor unit + semi-trailer with a length no shorter than the length of the loaded panels) with an open semi-trailer or one that allows for side loading on both sides along its entire length
• The load weight must not exceed the permissible load capacity of the vehicle combination,
• Transport straps should be placed on the load at intervals of no more than 3 m, but no fewer than 2 straps per package—the tension of the straps must not cause the slabs to deform.

Sandwich panels should be stored in stacks; a maximum of two stacks may be stacked on top of each other
The table below lists the maximum number of panels that can be stacked in a single stack.

• It is recommended to store the panels on a level surface (yard, warehouse) on joists or polystyrene pads, which must be spaced no more than 2.5 m apart (for panels with a total length of up to 2.5 m, use at least 3 blocks).
• A maximum of two stacks of boards up to 6 meters in height may be stacked on top of each other; stacks of boards exceeding 1 meter in height must be stored individually. All stacks of boards must be stored on a level surface with proper drainage.
• When storing panels on a construction site, they must be protected against mechanical damage, UV exposure, harsh environmental conditions (acids, fertilizers, salts, and other corrosive agents), precipitation, strong winds, and other factors.
• It is recommended to store packages under a roof in well-ventilated areas
• The panels should be stored on a level surface (yard, warehouse) on joists, on polystyrene or wooden supports, which must be spaced no more than 2.5 m apart (for panels with a total length of up to 2.5 m, use at least 3 supports).
• Protective films are used to provide additional protection for the surfaces of the panels against mechanical damage, stress, and impacts that may occur during transport or handling. These films do not exempt users from the obligation to properly secure the panels during storage.
• It is recommended to remove the protective film before installing the components on the building’s facade or roof. The film should be removed when the air temperature is above freezing, because at sub-freezing temperatures the adhesive delaminates and some of its components may remain on the sheet metal.
• Improper storage of the sheets may make it difficult to remove the protective film and may leave adhesive residue on the surface of the sheets. In such cases, the Manufacturer will not honor claims regarding adhesive residue left by the protective film.
• For panels with hidden fasteners, be sure to remove the film from the inside of the longer lock before assembly.

ATTENTION!!!

For wall panels with visible fastening, the top side of the panels in the package is the facade side; please pay special attention to this!

To extend the service life of roofs and facades made of coated sheet metal, they should be inspected and maintained regularly.

• Inspection – Once a year (preferably in the spring), you should inspect the roof and exterior walls to detect any damage early on.
• Cleaning Sheet Metal – Roofs and facades made of coated sheet metal require cleaning at least once a year. Dirt that accumulates on the sheet metal can cause uneven discoloration (due to uneven exposure to UV rays) and reduce corrosion resistance (dirt traps moisture on the sheet metal, gradually damaging it). Dirty and stained areas can be cleaned with a soft brush and water (max. 60°C). If necessary, a mild detergent (pH 6–7, max. 10% solution) may be added to the water. Pressurized water (max. 100 bar) may also be used for cleaning; however, the water jet must not be directed too close to the panel surface (min. 30 cm) nor perpendicular to the surface. At the joints, the water jet should be directed downward to prevent pressurized water from penetrating the gaps around the joints. Old panel coatings must be handled with extreme care. Cleaning should be performed from top to bottom, and the cleaned area should always be thoroughly rinsed with clean water immediately.
• Do not use scouring powders, nitro solvents, chlorine-based solutions, aromatic cleaners, or products containing ammonium chloride or sodium salts.
• Damage — Any damage that occurs during the Warranty period must be discussed with the roofing/facade contractor and may be repaired only with the contractor’s written consent. Repairs to small areas are carried out using air-drying touch-up paints, while painting large areas is generally only possible using special industrial paints designed for the renovation of coatings. The surface to be painted should be limited only to areas that require it (scratches down to the metal, corrosion spots, etc.). Surface preparation for painting should be performed in accordance with generally accepted guidelines. Always thoroughly remove all traces of corrosion—preferably using special brushes or fine-grit sandpaper. Next, the surface to be repaired must be thoroughly dusted, degreased, and cleaned. To degrease the surface, you can use extraction gasoline or water with added surfactants (preferably with a 1–2% ammonia solution). The repaired areas may show color differences compared to the original sheet metal colors due to natural atmospheric effects (aging of the paint under the influence of UV radiation).
• Organically coated steel sheets must not be used in:
  • an environment in constant contact with highly saline water,
  • contact with construction chemicals, including concrete, plaster, wet wood, etc.,
  • in an environment exposed to harsh chemicals
  • in combination with materials having a different electrochemical potential
• CAUTION—Health and safety rules must be strictly observed during inspection, cleaning, maintenance, and repairs.
