Installation Steps

Step 1 Fixing Joists

Determine the spacing between the two joists, 30cm is recommended for square hollow decking; 35cm for round hollow decking, and 40cm for solid decking. The spacing can be shortened as requested. Then, drill joists and fix them with expansion screws.

Step 2 Installing WPC Decking

1. When installing composite decking panels, a distance of 3cm should be maintained from the building.

2. Placing the first deck board to start your installation.

3. Connecting the two boards with plastic T clips & screws, the diameter of the hole should be less than 3/4 of the diameter of the screw to enhance the grip of the screw. The plastic T clips & screws are used to fix the spacing between the two boards to prevent sliding. (Knock the boards gently with a rubber hammer during the installation process to achieve equal gaps and a beautiful surface.)

4. Repeat this process until the last board. Then comes to the last step, set the edge boards on decking, and fix them with screws, then the installation is complete.
