Nowadays the long lasting composite decking boards are very popular, but that is all worthless if the frame will rot under the deck.

The trapped moisture is the main enemy of the joists and decking legs below, even if you cover them 

With our solid plastic joists, you can be sure that your deck will withstand any weather condition for long years to come, without any kind of maintenance. This will save you time and money, and let you enjoy your outdoor space hasslefree 

This frame material can be sunk into the ground without any protection, which means you can build your decking to ground level
