Hard Roofing

Thermal Conductivity

λ=0,024 W/m.K according to DIN 4108 and DIN EN 13165

The insulation values are regularly monitored by external bodies and may be applied without any further reduction.

Sound Insulation

R_w ≥ 25 dB

Corrosion Protection

• Standard version with external sheet 25 μm polyester and internal sheet ≈15 μm thin coating (DU)
• External sheet: category RC3; internal sheet: category RC2 (under the terms of DIN EN 10169)

External sheet: corrosivity category C3 corresponding to average duration of protection for urban and industrial environments with moderate exposure to sulphur dioxide.  

Internal sheet: corrosivity category C2 for dry indoor rooms and buildings with occasional minor condensation. Other coating systems are available for more sophisticated demands such as buildings near the sea, farm buildings with high ammonia exposure or moist rooms.

Standard lengths

> 2,00 m up to 25,00 m, greater lengths on request.

METCOLOR COATING SYSTEMS

STANDARD COATING FOR EXTERNAL APPLICATION
25μm POLYESTER

Corrosivity category RC3 in accordance with DIN EN 10169:2010-2
UV resistance category RUV2 in accordance with DIN EN 10169:2010-2
Temperature exposure -20° to 80°C
The well-proven polyester-coating is a modern and costeffective coating system, adapting well to different colour finishes. Polyester-coatings show good corrosion- and weather resistance under normal conditions for industrial application within the Central European region, which makes it the most frequently used coating system.

STANDARD COATING FOR INTERNAL APPLICATION
15 μm DU-POLYESTER

Corrosivity category RC2 in accordance with DIN EN 10169:2010-2
Temperature exposure -20° to 80°C
The polyester-thin-coating (standard colour shade similar to MC 9002) is suitable for conventional industrial buildings for indoor application in rooms with normal room climate and normal relative humidity. The colour shade may not be uniform due to the coating thickness.

25 μm OR 35 μm PVDF (POLYVINYLIDENFLUORIDE) - On request

Corrosivity category RC3 (25 μm) or RC4 (35 μm) in accordance with DIN EN 10169:2010-2
UV resistance category RUV4 in accordance with DIN EN 10169:2010-2
Temperature exposure -20° to 110°C
This coating shows optimal resistance against UV-radiation and weather and has good ductility. lt is suited particularly well for high requirements on the colour finish and has been found to be excellent in regions with difficult climatic conditions (e.g., 5-15 km from the sea).

Our recommendation for outdoors (indoors)
50 μm POLYAMIDE MODIFIED POLYURETHANE (PUR-PA) - On request

Corrosivity category RC5 in accordance with DIN EN
10169:2010-2
UV resistance category RUV4 in accordance with DIN EN
10169:2010-2
Temperature exposure -20° to 80°C
By using polyamide this coating system reaches a high surface hardness. lts visibly grained structure is particularly resistant to abrasion and ensures efficient protection against mechanical damage. lt is also widely resistant to strain by animals such as poultry, making it ideally apt for agricultural application. The flexibility and excellent resistance to UV radiation make this coating also suitable for outdoor installation.
