Sine wave profile

What is Sine wave profile?

The system belongs to the rain-screen family (wall cladding installed with a ventilated air space). This self-supporting system can easily be installed on a non-continuous supporting structure. sine wave profiles are installed on a metal framework fixed to the supporting structure (masonry or metal structure). The variety of effects which can be obtained from the play of light and shadow on sine wave panels.

Key Advantages:
Discrete Aesthetic rhythm of waves,
Technicité Horizontal or vertical cladding,
Technicité Self supporting cladding system from VMZINC on a metal framework.
  • Flat facades.

The support must be:

  • Rigid and continuous,
  • Meet loading requirements in conformity with a minimum pull out strength of 50 daN for each clip,
  • Rest on at least 3 bearing structure elements,
  • Have no protruding elements on the support.

Management of expansion

  • Vertical laying :
    Fixed section at the top (maximum authorised gripped length: 3 m). Expanding section at the bottom.
  • Horizontal laying :
    Fixed section at the centre (maximum authorised gripped length: 3m). Expanding section at the extremities.

Install fixed points with self drilling screws. Sliding points, whose diameter is adapted to the expansion differential between the substructure and the cladding, has to be pre-drilled in the sine wave profile cladding (about 2 mm greater than the diameter of the screws for wood and metal substructures in galvanised steel and aluminium).



Fixing screws
VMZINC recommends using:
- lacquered screws to match zinc's color.
- self-drilling screws for wood and steel.


The VMZINC sine wave profile is fixed using structural screws(1) at each support, in every second wave bottom. Where there is overlapping, two screws(1) are placed successively in addition to non-structural screws(2) which will be fixed between the structural fixing elements.

Note: The design of the framework and the dimensioning of its fixing elements are not part of the range of services offered by VMZINC.

Screws for wood framework

  • drilling capacity to: 2,25 mm.
  • minimum dimensions: 4,8/35.

VMZINC recommends the use of 18/8 stainless steel screws for treated woods.
Zinc coated (galvanised ) steel screws can be used for untreated wood at the company's discretion. The installation company must check that the loads are compatible with the stresses caused.


Screws for metal substructure

  • drilling capacity: 3,5 mm
  • minimum dimenstions: 5,5/25

VMZINC recommends the use of 18/8 stainless steel screws.
Zinc coated (galvanised ) steel screws can be used for single skin cladding in the case of Zinc coated steel frameworks. This is at the company's discretion.
