How to build a small deck using modular decking kit and adjustable supports?

[martyjames]

After further research and helpful input from you guys i am now planning to build an approximately 3m x 3m deck (no pergola) over a slightly sloping concrete slab in my backyard (pic attached).

I am a very basic diyer so want simple and easy to understand but want the deck structurally sound and long lasting.

I found Bunnings sell Modular Decking Base Frame kits like https://www.bunnings.com.au/1144-x-1144mm-modular-decking-70-x-45mm-ekodeck-base-frame-flat-packed_p... etc

I am thinking to use 9 of these kits 1144mm x 1144mm to get a base roughly 3.5m square.

I will use the Modular decking support feet to level the frame : https://www.bunnings.com.au/50mm-modular-decking-adjustable-support-foot_p8451224

I watcheds this video from Bunnings on how to put it all together: https://www.youtube.com/watch?v=1tjQdmsmkP8

Over the to of the frame i will install composite decking

Quesions

1.The video does NOT show the frame being attached to the ground at all - does it need to be? If so how would i attached it to the concrete slab? ( i can easly attach to the low wall at back of yard - is that ok?)

2.Can you send me a link to the correct "battern" screws refered to in video

3. How would i work out which length of Modular decking support feet to buy? They come in 50/100/150mm lengths from your website

4. Is the Modular Decking Base Frame kit timber 100 percent weather proof and does not require any finish?

5. I am thinking i need a very long spirit level to ensure frame is level - can you please provide a link to suitable level

6. Can you send me a link for suitabe screws to screw the frames together if different from "battern" screws in no.2 above

Is there anything else i need to take into account or buy?

Thanks in advance
