Aluminium system profile

The alternative to wood deck substructures

In contrast to wood substructures,

the profile is dimensionally stable.

There are no faults, cracks, etc. caused

by the weather, as with wood

when used as a building material.

 
Dimensionally stable, straight and load-bearing

Aluminium system profiles are the alternative to wood deck substructures.

• In contrast to wood substructures, the profile is dimensionally stable. There are no faults, cracks, etc. caused by the weather, as with wood when used as a building material.

• The system profile is always straight. In contrast, substructure woods may be curved lengthways and for this reason often have to be stiffened crosswise to enable a straight line of screws.

• Because of the profile‘s special shape, deck coverings can be screwed both directly and indirectly. With direct screwing, the offset web ensures that the screw has room to move without shearing off.

• The system profile can, of course, be supported directly with Rolfi deck spacers.

 

Spans for aluminium system profiles in mm

a) Specification of the max. span with which the deflection of the profile does not exceed L/600

b) Example: clearance of profiles to one another = 550 mm, useful load = 2.0 kN/m² → max. span of profile = 800 mm

c) Useful loads in accordance with DIN 1055-3:2006, roof terraces = 4 kN/m², terraces in public = 5 kN/m²

Aluminium function strip

The substructure for wood decks with low assembly heights

  • with glued-in cork insert, »Free of PAHs« (hazardous plasticisers in rubber).

  • Very low assembly height, eg profile height 29 mm + board 24 mm = 53 mm

  • the self-adhesive cork insert is free of PAHs and ensures good footfall sound insulation on the underside of the profile.

  • Aluminium does not rust and is extremely weather resistant

The aluminium function strip is excellently suited to the construction of timber decks that cannot be built to a large height, e.g. building over stone patios, on balconies and on roof terraces.
