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.

• Cut to size, weld or fasten cable ends.
• Clamping via two flat iron bars.

The fabric must be stretched in the warp direction.
