Composite Floor Grating

The composite floor grating is a floor to walk on. Like a wall it sits on one face of the large 2 m grid and, according to the game data, is 0.13 m thick, as thick as a composite wall.

It is quick to build: the Kit (Floor Grating) is placed in a single step, no further sheets or tools needed. It is removed with the crowbar. The kit comes from the Autolathe and only costs iron. It also makes three further grating forms, open and rotated variants and an open platform with a ladder.

The grating is not airtight. According to the game data its build state lets air and light through – the same goes for the other grating forms and the open variants. So gas flows straight through: a room with a grating floor shares one air space with the room below, and if the outside is below, the room is not sealed. That is also why the grating has no pressure limit – no pressure difference ever builds up across it.

For the floor or ceiling of a pressurised room use a Composite Wall (Type 1) with 300 kPa. The grating belongs on galleries, mezzanines and walkways inside a pressurised room, where air may pass freely.

According to the game data it is flammable, with auto-ignition only from 873 K. How floors, walls and stairs fit together is shown in Building: frames, walls, windows, floors, grid.
