ARTOS Sigma – Series (Sigma 1 – Sigma 6) is a fabric with high translucency, flexible in the direction of the warp and stiff in the other direction. Variable in its weave ability with 2, 3 or 4 warps and customizable in the mesh size, you can reach a great range of openness. Suitable for wall- or ceiling coverings, on facades or as sun protection, as well as for banister fillings or balconies.



Stainless steel Standard V4A

(Option V2A possible)

In the German-speaking world, two different blanket terms are used for VA stainless steels. The two most common are “V2A” and “V4A.” Both grades are found in all ARTOS products.


V2A Stainless Steel

(alternative designations: product no. 1.4301, AISI 304, and X5CrNi18/10)


A commonly used stainless steel found in everyday applications, e.g., metal construction, such as vehicles and sinks, and in the food, pharmaceuticals, and cosmetics industries.


NOTE: V2A should not be used in coastal environments (due to salty air and drifting sand), in metropolitan areas (due to acid rain caused by smog), or in swimming pools (due to the high chlorine content of the surroundings). Only V4A materials are suitable for these applications.


V4A Stainless Steel

(alternative designations: product no. 1.4404, AISI 316L, and X2CrNiMo17-12-2)


Similar to V2A stainless steel but is additionally alloyed with 2% Mo. This makes the stainless steel more resistant to corrosion in chloride-containing media. V4A stainless steel is used in saltwater, swimming pools, and the chemical industry.

The specification “light transmittance TL in accordance with DIN EN 410” applies to the wavelength range of 380–780 nm for visible light. It is weighted according to the brightness perceived by the human eye and given as a percentage. With the absolute reference of 100%, e.g., a wall opening is meant.


Fall protection

Product can be used as a fall protection.



max. 8.50 m web width

  • Cut to size, weld or fasten cable ends.
  • By default, larger round bars are introduced into the fabric for fastening purposes. Alternatively, the fabric can be clamped with two flat iron bars.

Sub construction

Clevis brackets

Brackets for round bars

The fabric must be stretched in the warp direction.

Dinslaken spiral car park /Germany

The cladding of the spiral car park for the newly erected shopping mall ‘Neutor Galerie’ held a challenge, as the client required a semi-transparent covering producing various light effects. Through the use of our ‘Sigma 3’ type fabric we were able to emphasise the geometric form of the circular spiral and satisfy the requirement for a light and homogeneous cladding material.


The fabric webs with web widths of 2.00 m and various lengths according to the slope of the ramp were suspended next to each other. The total amount of fabric corresponding to the unwound surface area was 812 m².


The building is illuminated at night and the stainless steel surface reflects the incoming light in a dramatic and imposing way.


A newly developed solution from ARTOS was implemented to enable nearly completely concealed fastening at the middle of each web on every level.


Although the ARTOS team became involved very late in the project, it was still possible to complete the planning, manufacture and installation within six weeks.
