The fireproof curtain manufacturing process constructs a folding assembly of wire, which is covered with a cladding layer. The wire can be coiled and knotted to form the folding assembly, and can be zinc-or chromium-plated steel. The cladding layer can be of foam material, also acting as paint, or a layer of varnish can be applied and hardened by quick-drying. Alternatively a layer of inorganic glue can be applied, to which fibres are in turn applied electrostatically. The glue and fibres can be applied after the varnish, and glass fibre can be used.
