The width and length of each sheet metal blank may vary by up to +/-2mm. Please note: these sheet metal cuts are not intended for decorative or visible applications. They are cut using guillotine shears, so the edges are sharp. Not all sheets come with a protective film, and the surface is industrial quality, which means scratches may be present.

Thanks to passivation, zinc is resistant to air, and it can be processed into powder at 220°C. In powder form, zinc is pyrophoric and may ignite spontaneously in air at room temperature. Zinc dissolves in acids, producing salt and hydrogen, and also dissolves in alkalis to form zincates. Notably, high-purity zinc (99.999%) is resistant to acids.You can purchase zinc from Evek GmbH’s online shop, where a variety of metals are available.
