The Benefits of Steel in Facade

3. Wind Load relative deflection The modulus of elasticity of steel is three times higher compared to aluminium For identical profile cross sections the deflection of Aluminium is more

4. The modulus of elasticity of steel is three times higher compared to aluminium For identical loads and identical deflection smaller steel profiles can be used.

5. advantages RP-steel facade The modulus of elasticity of steel is three times higher compared to aluminium Larger spans can be achieved with steel profiles by using the same cross sections.

6. Minimize framework Larger span width with steel Typical visual characteristic of facade systems in Aluminium STEEL

7. Steel Reduced box sizes Result Lower building depth are possible with steel compared to aluminium

8. Large Spans Result Larger span widths are possible with steel compared to aluminium Facade of 14m width and 48m height without expansion profiles

9. Visable environment profile depth 160 mm Visible Sightlines

10. Visable environment! Stahl Increased Light Transmission

12. Panelized Glazed Elements Reduced Program times 13m x 5m

13. aluminium timber Modulus of extension ! Steel has a lower thermal extension than aluminium! Steel, glass, concrete have almost the same coefficient of extension, therefore no extension profiles are required when using steel. glass concrete steel +10°C +20°C +30°C +40°C +50°C 9,0 10,0 12,0 24,0 42,0 x 10 x 1/K -6

14. 167m without Expansion profiles Advantages RP-steel facade

16. Modulus of conductivity λ (W / m x K) U f = 1,8–2,1 W/m²K U f = 1,4 W/m²K Steel Aluminium Reduced Thermal Transmissions - Lower transportspeed of coldness - Rare condensation - high transportspeed of coldness - condensation Steel ~ 50 Aluminium ~ 200

17. Snow Center Dubai Snow Center Dubai Reduced Risk of Condensation RP-steel facade Aluminium facade

19. advantages RP-steel facade 6. Fire resistance Fire resistance of steel is considerably higher than that of aluminium. melting point steel = 1.500°C melting point aluminium = 660°C 7. Ecology Substantially lower energy consumption during production of steel as compared to that of aluminium. No toxic product waste with steel production.
