ATTENTION! Considering that dark colors from group III are subject to much larger thermal loads than boards in very light and light colors from group I and II should be assessed depending on the loads, what plates system on the wall is possible to be used.
* The colors marked with the star are not available in the standard offer. Please direct individual queries in terms of colors using the contact form.

Recommendations for the selection of plates in the context of thermal loads

ATTENTION- III group – dark colours

Taking in consideration that dark colours from group III has much bigger thermal load and very bright and bright colours from groups I and II, there should be paid special attention during projecting and below conditions are complained:

Way of assembly and static scheme must be in accordance with chart of maximum load and span length(complain conditions – limit status of bearing capacity, limit status of use)*
Max length of panels should be limited due to producer’s guidelines**
Temperature during assembly***

* For panels with dark colours recommended are single-span schemes; in other case there may occur non-acceptable by Investor strains on external claddings on panels on intermediate supports. Flutings which may occur, complain with norm PN EN 14509 due to acceptable deviation, but may be topic of complaints.

** Maximum length of panels should be in accordance of producer’s guidelines due to type and use of panels – see LENGTH OF PANELS

*** Assembly of panels with dark colours is possible within temperatures 10^oC to 35^oC. This condition is essential and must be strictly observed.

Assembly of panels in very bright and bright colours is possible within range of temperatures from +5^oC to +35^oC

Transport recommendations

Recommended ways of transport for sandwich panels:

semi-trailer truck (tractor + trailer of length not longer than length of loaded panels) with open platform or trailer which enables loading from both sides on full length
transportation belts should be assembled on panels max. each 3m, but not less than 2 belts for one package – tension strength of panels should be putted correctly to not damage panelsp

Storage

Sandwich panels should be storage maximum 2 packages one on another.

In below chart you can see what is maximal quantity of panels in one package.

thickness of panels	PWS
60 mm	18pcs.
80 mm	14pcs.
100 mm	11pcs.
120 mm	9pcs.
150 mm	7pcs.

All packages should be storage on flat surface with possibility to discharging water.
ATTENTION !!!

It is allowed to storage maximum 2 packages of panels with length up to 6m one on another, in case of packages with length higher than 6m these packages should be storage separately.
During storage of panels on building site, packages should be protected against mechanical damages, UV rays, aggressive conditions(acids, fertilisers, salts and other corrosion factors), precipitations, strong wind etc.
It’s recommended to storage packages under roof in ventilated facilities.
Protective foil are used as additional protection of surface of panels from mechanical, stress, damages which may occur during transport or loading/unloading. However foils never dismiss from duty of correct protection of panels during storage.
It’s recommended to remove foil before assembly of panels on elevation or roof. Removing of foil should be done during positive temperatues.
Protective foil should be removed during 1 month of production date, even when panels are not assembled yet.
Improper storage may cause difficulties when removing the protective foil and leave glue marks, in this case complaints won’t be accepted by Producer.
In case of panels with hidden fix, there should paid attention that foil is removed from inside longer lock before assembly.

Maintenance

In order to extend durability of roofs and elevations it’s recommended to check and conservative it.

Inspection – One time a year (it’s best in spring) there should be inspection of roof/elevation in order to early detection of possible damage.
Cleaning of steel sheet – Roof and elevation made of steel sheets require cleaning at least once a year. Stratifying dirt on steel sheet may cause uneven discoloration of lacquer (because of uneven impact of UV beams), and lower protection to corrosion(dust traps humidity on steel sheets which causes damage). Dirty and stained spots can be cleaned by soft brush and water (temp. max. 60c). If it is necessary it is permitted to use some light detergent (ph 6/7, max 10% solution). There also can be used pressed water(max. 100bar) to cleaning, however the beam of water cannot be applicated too near of surface of sheets(min. 30 cm), also it shouldn’t be perpendicularly to surface. Near the connections water beam should be directed to bottom, to avoid water of entering cracks near connections. With old surfaces of steel sheets we should deal with high cautiously. Cleaning should be conducted from top to bottom, and cleaned spots should be rinsed out immediately.
It is not permitted to use scouring powders, nitro solvent, chlorine liquor, aromatised substances, substances with Amon chloride or sodium.
Damages – Possible damages during guarantee should be consulted with Contractor of roof/elevation and can be repaired only with his written permission.Repair of damages on small surfaces is done with quick-drying varnish. However painting big surfaces should be done with special industrial paints to renovating coverings. Painting should be limited only to special damaged spots (scratches to steel, centres of corrosion etc.)
Preparation of surface to painting should be done with generally accepted rules. It is necessary to precisely remove all signs of corrosion – best with special brush or close-grained sandpaper. Then that surface should be undusted, degreased and cleaned. To degrease extraction naptha or water with addition of surfactant(best with 1-2%solution of ammoniac) can be used. Repaired spots may be different in colour compared to original steel sheets because of natural impact of atmospheric phenomenon (ageing of varnish due to impact of UV radiation)
