Entry door D-ONE : AT

steelgalvanized steelswing

Security door with double bit lock The AT security doors stylishly open to any furnishing requirement, but become inflexible in the event of break-in attempts. A structure made of galvanized steel, anti-unhinging ties, fixed grips, seam welded hinges and the double bit lock Lock Trap System, are, in short, their strength. With single or double leaf and service lock, AT offers an overall protection with excellent performance: the door is, in fact, certified burglar-proof in class 3 (in class 4 on request) and also ensures a 39 dB acoustic insulation and a 1.8 W/mqk thermal transmittance (single leaf versions).
