I have checked few quotes for grill. Cheapest 3850. Powder coated / Mild Steel / 1 mm thickness. 

Price includes 1 door, 1sliding door, 3 toilet, 4 rooms and yard for washing machine + 4' plat .

I got quoted from 3 Kim RM3077 (powder coated + angle bar frame) for entire house door & windows (including kitchen). If you plan to grill the washing machine area then additional RM1462.5 (powder coated + hot dip galvanize).

Material is outer frame 25 x 50 x 1.2mm RHS with horizontal design 19 x 1 Round tube @ gap 4"

So total pricing is about that ~RM4500.

Your awning covers how many total sqft? 20' x 5'?

For grilling your kitchen door and window after grilling w.machine area is entirely up to you. Of course multi-layer security is better than single layer.

Owner of Saron 1 here. Just got a quotation for grill. Total house including the back area cost around RM 2.7k for normal paint. I think this is the best price given to me. Anyone getting any cheaper. According the installer if powder coat need to add around 700 to the price
