Recommendations for the selection of plates in the context of thermal loadsDuring projecting it’s important to include difference in temperature of external and internal cladding of sandwich panels.Gradients of temperatues due to difference in external temperature T1 and internal temperature T2 are dependent on few factors:
Purpose of building (range of temperatures inside building T2)
localization of building – position due to sun
colour of external steel cladding (T1).
Depending on latitude, height above sea level and distance from sea on europe continent are use 4 different levels of winter temperature (T1 – external cladding):
0, -10oC,
0, -20oC, (for ex. Poland)
0, -30oC, (for ex. scandinavian countries)
Temperatures of external cladding of roof panel which is covered with snow layer is 0oC.
For calculation was assumed external temperature in winter of -20 oC.
Temperature of external cladding T1 has maximum value during summer and is depending of colour and grade of reflection of surface. Values T1, which are minmal for calculation bearing status (SGN) and are proper for calculations of limit status of use (SGU) are:
- Very brigth colours RG = 75-90 T1 = +55oC
- Brigth colours RG = 40-74 T1 = +65oC
- Dark colours RG = 8-39 T1 = +80oC
where RG – grade of reflextion in ratio of magnesium oxide = 100%

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 | PWD-PIR |
|---|---|
| 40 mm | 18 pcs. |
| 60 mm | 14 pcs. |
| 80 mm | 10 pcs. |
| 100 mm | 8 pcs. |
| 120 mm | 8 pcs. |
| 160 mm | 6 pcs. |
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)
ATTENTION!
- During inspecting, cleaning, conservation and repair all work safety regulations should be obeyed.

Product description
Panel with visible fastening
PIRTECH ROOK (visible mounting) boards with a maximum modular width of 1050 mm allow for simple and quick installation to various types of structures with the help of Kalotka and appropriate through fasteners.
The uniquely designed longitudinal contacts (locks) of the pen and wpust ensure very good tightness, fire resistance and quick assembly. The shape of the outer surface (trapezoidal profile) allows you to carry high loads as well as can be used in single -span and multi -span systems
When connecting roof slabs in length, it is necessary to cut the upper plate, i.e. the plate from the ridge side.
Pirtech roof plates can be produced with ready undercut in the range from mins 50 to max 300 mm.
Just choose the type of undercut (see Fig.), Which is determined by the direction of assembly:
- Left undercut – assembly from the left
- right undercut– assembly from the right
The undercut length can be: D = 50, 100, 150, 200, 250 and max 300 mm.
Note: The total length of the plate contains the selected undercut length regardless of its size.
For example, a 6000 mm long plate with a undercut of 200 mm = 6000 mm (5800 mm core + 200 mm sheet).
Blachy Pruszyński performs two types of undercuts:
– full undercut, i.e. an internal sheet cut, tape on the outer trapezoidal cladding, undercutting of foam along the entire thickness of the plate core,
– incomplete undercut, i.e. cutting the inner sheet, undercutting of foam along the entire thickness of the core of the plate.
Individual undercut widths (regarding the range only from 50 to 300 mm) are possible, but without a tape on the outer – trapezoidal cladding with undercut of foam along the entire thickness of the core of the plates.
For PWD-PIR 40, 60, 80, 100, 120 min. The length of the plates with full undercut is 5,000 mm. Plates in lengths below 5,000 mm can only be made without a tape on the outer – trapezoidal cladding.
For PWD-PIR panels 160 min. The minimum length of the panels with full undercut is 4,000 mm. The PWD -PIR 160 board in a length of below 4,000 mm can only be made without a tape on the outer – trapezoidal cladding.
