Panel with covered fastening PWS-PIR-PL-60

* 1050 mm - standard module, 1000 mm - non -standard module
** Approximate mass masses are given for the thickness of the external sheets. 0.50mm and internal 0.40mm and standard module.
Allowed length of panels depending on colour of cladding (minimal length - 2,5 m) for single-span scheme.
13,5 m
12 m
9 m
During 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:
where RG – grade of reflextion in ratio of magnesium oxide = 100%
Recommended ways of transport for sandwich panels:
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-PIR-PL |
|---|---|
| 60 mm | 18 pcs. |
| 80 mm | 14 pcs. |
| 100 mm | 11 pcs. |
| 120 mm | 9 pcs. |
ATTENTION !!!
All packages should be storage on flat surface with possibility to discharging water.
In case of panels with visible fix(PIR-ST), upper side of package is elevation side, which is very important.
