The telescopic hatch system ladders are made of cathodic E/D coated steel with a thickness of 20µm. This coating process assures high durability in a variety of climates. The telescopic hatch systems ladders are tested for water resistance (over 500 hours at 40°C), humidity (over 500 hours at 50° and RH 98%), and salt water spray (over 800 hours (JIS Z 2371 35°C – 5%).
The hatch system ladder is composed of a frame and a telescopic ladder. The frame has a top and bottom cover that can be opened. The ladder is fitted inside the frame using bolts that are already present in the frame.
The frame of the hatch system ladder is installed in the floor of the balcony to reduce visual impact. It can be casted into a hole or fitted onto a metal structure. It is anchored using lateral angle pieces provided with the ladder.
