When using wholesale aluminium composite panels, the indoor adhesive method is to use wood plywood as the base,
use special glue to stick the open boundary aluminium composite panels on top of the wood plywood,
and put sealant between the joints of the aluminium composite panels.
In the case of the outdoor dry hanging method, the aluminium or steel keel is used to support the sub-frame,
and the aluminium composite panel made into a box-like board is hung on top of the keel with self-tapping dowels,
after adjusting the keel to take the level, the foam rod is filled between the aluminium composite panel and then sealed with sealant.
Before the installation of the aluminium composite panels, attention should be paid to levelling the original wall base and then to the bullet line,
the main purpose of which is the precise elevation control line and the keel layout line,
according to the specifications of the aluminium composite panels and the ceiling area to determine the size of the ceiling skeleton.
When leaving the edges around,
the dimensions must be symmetrical, the determined keel frame position line is drawn on the upper side of the elevation line,
and the wall is also perforated and fixed with wooden dowels.
