What joist spans should I use for my dock, deck or walkway when using ThruFlow Premium Decking?

The joist spacing should be 16″ on center for all applications (18” for 3’ Product, 15″ for 5′ Product), which is the same span generally recommended for wood. Special applications/loading conditions will require engineering analysis and/or reduced spans, please consult and adhere to your local building code.

Please consult with your local contractor for regional requirements and/or restrictions.
