Materials and cost for decking project

Robin074

I would like to build a 5x3 deck using ,your code 012077 decking, how many would I need, also the cost,   I couldn't find how to ask for a quote to supply and deliver to Muswellbrook, could you please also comment on what I would need to stop weeds growing through, I was thinking on wooden frame to add the decking too, or would you suggest steel C section a better option I have a welder.

Welcome to the Bunnings Workshop community @Robin074. It's wonderful to have you join us and many thanks for your question on deck construction.

I can't locate the product you are referencing. Could you please check for a seven-digit number or provide the link to the product? You can use this deck calculator to work out how much decking you'll need for your project. For 90mm Merbau decking, you'll require around 174 lineal meters and that would be $1084. For 140mm Merbau decking, you'll require around 114 lineal meters and that would be $1242. Once you know how much decking and timber you'll need for your project, you can call Bunnings Singleton on (02) 6575 9800 and a team member will be able to organise a quote for you.

The best place to start with constructing a deck's frame would be with @Adam_W's article on How to build a low-level deck. Generally, when steel is used for deck frames, it is in the form of prefabricated deck joist sections. If you have the ability to weld together a complete frame from C section, then it could be a viable solution. H3 outdoor framing timber is suitable for above ground use and needs clearance under it. If the frame is to be in close contact with the ground, it might be a better idea to go with galvanised steel. Though, the coating would pose an issue with wielding it.

If you are concerned with weeds growing through the deck, I'd suggest laying weed matting down over the solid before building your frame.

I look forward to following along with your project. Please let me know if you have any questions.
