1. Panel roofing specification MPR-80
Roof panel is composite of two skins the upper sheet is aluminum thick 0.7
and the lower sheet is prepainted galvanized steel thick 0.5 mm the isolation
material is Polyisocyanurate foam (PIR fire retardant)

Aluminum coating substance:
Pvdf color Ral 9002
The resistance against external environment, high corrosion resistance, and durability
against the chemical oils are provided. It provides high resistance against chemicals and UV
ray proofing. The durability of the color and brightness resistance is the highest coating
type, approx. thickness is 27 micron, heat resistance 120 0C.

2. 2- lower sheet prepainted galvanized thickness 0.5mm, G90 (275-300 g zinc/m2)
The corrosion resistance of the galvanized sheet is very good. The galvanized sheet resists
against the corrosion for over 40 years under normal ambient conditions. The protection
period is over 25 years even under the heavy conditions (industrial conditions and sea
side).
The galvanized sheet is hard and resistant against the wear and tear and strokes. The
painted galvanized sheets that we use in our production do not require any maintenance.
Therefore no additional investment is required except the initial investment. The
production of the galvanized sheets does not lead any environmental harm. On the other
hand the galvanized sheets are easily recycled and reused.
Physical Features of Prepainted Galvanized Steel
Steel quality (EN 10327) DX51 D+Z
Tensile Strength 500 Mpa (max)
Elongation (%) 22 (min)
Hot dip coated steel grade (EN 10327) 275-300 g.zinc/m2
Polyester coating substance Ral 9002:
The high resistance high flexibility and heat balance are provided against the external
ambient conditions. It is the most widespread painting type. It used in the inner and
external ambient.
Paint thickness 25 micron

3. 3- Insulation material foam (PIR)
Polyurethane is a plastic polymer established with the reaction of the isocyanides having
NCO and poliol with OH group. The participation reaction is the polymerization reaction
fully, and it is the immediate lower group of the plastic family. Polyurethane foam is
obtained with the composition of the following four raw materials:
Poliol
Isocyanate
N-Pentane-Blowing agent
Catalyst

Shear strength after long-term loading (fcv-long-term) t:1.000 hours min. %35
Compression Strength min. 0,095 MPa
Tensile Strength min. 0,018 Mpa
Heat resistance (ºC) -200 / +110 °C
Dimensional Durability (EN 13165) Level DS(TH) 11

4. 4- FASTENING SYSTEMS
Various fittings are used for the fixing of the sandwich panels and single layer trapezes to
the carrying construction in façade (siding) and roof coatings, such as accessorized joints.
The resistance, water proofing, appearance and etc. of the fittings should be preferred
meticulously during the design phase.
Stainless Steel Screws
Thickness of sandwich panel construction can be mounted 1, 5 mm - 5, 0 mm
