In view of the properties of wood plastic decking for outdoor use,we have to take following key points in consideration during installation:

1.Make sure the ground stiff and flat,like concrete ground.

2.Keels are to be required for WPC deck and wall cladding.The distance between two keels is around 30-35cm

3.At the joint of two planks' ends,double-keel shall be applied.

4.Reserve small gap(5-6mm) during installtion,for example,adjacent planks,and joints of planks or keels.
