Assistance wanted for building a low-level deck

Hi all, I noticed that someone below received design info for their deck. Could I ask for the same assistance. 

Single layer deck.

Deck Size is 6m x 6m,

bearer timber 140 x 45mm

Joist Timber (Cut-in between each bearer) 90 x 45mm

Decking specifies Joists approx every 16" but I'm sure there is some flexibility in that.

 

Appreciate any assistance or a plan.

Re: How to build a low-level deck

Welcome to the Bunnings Workshop community @eventswestjohn. It's amazing that you've joined us, and many thanks for your question about deck construction.

 

How high is your deck from the ground? You might need to have a search for a deck calculator that would work with your design approach. The calculator used above does not support that functionality. Typically, you would either run the joists over the bearers, or for a single layer deck, have the joists by themselves with noggins between them.

 

An option would be to have the 140 x 45mm timbers spaced every 450mm across the 6000mm span and lay the decking perpendicular to them.

 

Please let me know if you have questions.

Re: How to build a low-level deck

Thanks for your reply Mitchell.

I understand your suggestion. There is only about 200mm or so. If running the 140 x 45 across the whole 6m span, would that not mean there would be 'a lot' of posts / supports required and they would need to be on every one?

 

Regards

John

Re: How to build a low-level deck

Hi John (@eventswestjohn), 

 

You are correct that there would be lots of supports across the span. That's one of the issues with a single level deck. Here's a recent discussion from @Fadi about their Low level decking over concrete. You'll note they are planning on using 44 supports over their 6000 x 2000mm area. If you check out some timber span tables, you'll able to work out the maximum 140 x 45mm can span un-supported.

 

What is the deck being built above?
