The main use of aluminium composite panel wholesale products is for curtain wall,
indoor and outdoor decoration, etc.,
where the curtain wall is the external protection member of the building,
not accepting the main structure load, mainly accepting the self-weight,
wind load, earthquake effect and temperature effect.
Self-weight is gravity load, often the effect of the invariable load,
because of the small density of aluminium composite panel,
so the mass of the stress occurred small, not the main effect.
Variable load for the vertical construction of the curtain wall wind load is very important,
the value of up to 2.0-5.0KPa, as for the effect of the earthquake,
it is because the aluminum composite panel is light,
even according to the maximum earthquake effect coefficient, but also 0.1-0.8KPa,
far less than the wind, and the temperature effect is also very small.
Therefore, aluminium composite panel as curtain wall material,
wind pressure resistance is the element to be considered.
In the wind vertical effect on the aluminium composite panel,
the aluminium composite panel first deformation of zigzag,
so zigzag strength and zigzag modulus of elasticity is one of the important functions and parameters of the curtain wall aluminium composite panel.
