UniGear ZS2 – Main charateristics Long life, modern design ! Construction with AluZinc steel sheet Bolted design The aluzinc is iron, laminated with a metallic covering: The iron gives physical strength, while the alloy covering (aluminium-55% & zinc-43.4%) gives a good resistant to corrosion; Aluzinc does not distort at high temperatures (up to 310°) and outlasts traditional galvanising by between 2 & 6 times. The panel is fully type tested according to IEC standards including Internal arc test which ensures the operational safety of the overall system. The panel is one of the most compact AIS in the world which also offers outstanding space savings with optional wall-standing solution.
