how to install the keel of wpc flooring

Step 1: If you install brackets in the walkways of ponds/lakes, parks, and landscape ecological agricultural crop parks, plants need to be taken care of. It is not possible to pour concrete in a large area in the lake drainage area. You can directly install the galvanized screws underground, and then weld the galvanized pipe keel to the ground. If it is installed on a lake, pond, or a place with high humidity, it is recommended to use a hot-dip galvanized square pipe to avoid corrosion.

Step 2: Concrete foundation on the ground; The concrete shall be flat, and the concrete thickness shall not be less than 8mm; Therefore, we can directly fix the WPC flooring keel on the concrete floor with a plastic expansion plug.

Step 3: If the installation surface of the pure soil floor and WPC flooring needs to be raised, we can first dig the foundation pit and bury the concrete and galvanized pipe column. Generally, the diameter and depth of the foundation pit shall not be less than 300mm, the specification of galvanized pipe for column shall not be less than 60*60mm, and the pipe wall thickness shall not be less than 2mm. The column spacing shall be controlled within 1800mm; After the column is embedded, the galvanized pipe keel shall be welded on the column. The recommended specification is above 40*60mm.
