Decking Sub-Frame

A decking sub-frame is the structure that supports the deck.  It is typically made from timber and consists of posts, joists and beams which are arranged like a grid.  This keeps your deck secure, level, safe and ensures it lasts for many years to come.   The decking boards are then fixed to the sub frame. 

Always use high quality materials for your decking sub-frame.  It will give you a secure deck and ensure you avoid common issues like deck sagging or wobbling.  A solid foundation keeps the deck level and helps prevent water pooling which can damage decking boards over time.  

During construction, consider drainage and moisture management.  Always make sure the area below the deck drains effectively and dries quickly after rain.  It is important to make sure your sub-frame is anchored effectively to the ground or other structures, so that it is secure for years to come. 

The sub-frame is the most important part of your new deck, investing in high quality materials and high-quality construction will make sure your completed deck looks great and is secure.  Timber decking and composite decking is available.
