ARTOS Sigma – Series (Sigma 1 – Sigma 6) is a fabric with high translucency, flexible in the direction of the warp, 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.
Product can be used as a fall protection.

The wave shape of the ceiling leads the visitor to the counter. At the same time the dynamic wave reflects function and character of the room. This zone invites to move on, you just pass through and enjoy the cool elegance.
This atmosphere is crated by sophisticated material such as our sigma 1 which is effectively set into light. The result is a bright, vast area that obtains its special effects by translucent materials.
