The base is the same orthophthalic polyester resin, but with fire-retardant components added. This gives the grating fire-resistant properties and better resistance to chemical agents, while the price stays close to the basic series.
ALPINA GRATE gratings have been tested to ASTM E-84 (tunnel test). Depending on the resin type, they achieve Class 1 with a flame spread index of 5–25 or lower. Test reports are available on request.
Non-conductive, non-magnetic and non-sparking — important in rooms with electrical equipment. No rust, no painting, a service life of 30–40 years and more. The panels are light: they are cut on site and installed without a crane.
