Can anyone please tell me what is the standard thickness for flat bar door and window grille. The grille supplier told me standard is about 0.5". This is about as thick as a hollow bar. How can it be?

Maybe he's really generous with his steel 0.5 inches of solid steel ... the grille must be damn heavy.

0.5" is more likely the width of the flat bar.
Sure you did not hear wrongly?

I guess it was correct, stardard sliding door grill are using 0.5" bar where internal are empty type and it squre.

Is not the thickness on the metal lal.

0.5" width or 0.5" thick
seriously, if its 0.5" thick, we call it solid bar not flat bar

normally grill guy will give u 3mm(thk) x 12mm/16mm flat bar, if u got for 5mmx25mm flat bar, price & the weight of the grills also

pic of my house grill taken just now, 5mm x 25mm flat bar on 1"x2" RHS



the std SHS/RHS 0.5" thickness only <=1mm, so its very light and can be cut easily.

My Grill is 0.5" (inch)...a standard type

I think everyone is right, supplier must be refering to width not thickness. But I did comment that with that 'thickness' its going to look like hollow bar and he said is standard 'thickness'. But now I'm sure is miscommunication, will ask him again. First house so clueless about everything! Thanks everyone.

Added on August 16, 2011, 10:28 pmJo-da, your grille looks like flat bar with the width instead of the thickness facing out. Is it because your grill design is horizontal and vertical bar? I see a lot of flat bar design with horizontal lines only.

Yes , I think the si-fus here are correct, It should be 0.5" width (inside hollow).
I went to the grille guys previously and they show me 0.5" X 0.5" hollow square metal tube / bars.
There is also 1" X 0.5" hollow square metal metal tube / bars.

It is Vertical and Horizotal line too...it is almost 10 years old design but still use by lot of people lol

That's called square hollow section (SHS)

can share the price of yr 5mm x 25mm flat bar on 1"x2" RHS?? TQ

My Grill contractor quote me with the following description, so is much easier.

1. for your front door outer frame 1"x1", inter frame 1"x2", gap 4" for
vertical bar, gap 2" for vertical bar

2. door n window grille: material size 1"x1/2", see from front 1"

3. gate: material size 1"x2", gap 1", see from front 1", frame 1 1/2"x 2 1/2"

4. fencing: material size 1"x1/2", gap 2", see from front 1"

usually thickness is 1.2mm for infill 1" x 2", and smaller usually 1mm thickness

Do they give you option for hot dip galvanize?

Hi,

Can share (PM) with me the price & the contacts of contractor for your grill..?

Cheers &TQVM

this is what i got fm tiga-kim:

Mild Steel Window Grille with outer frame 19mm x 19mm x 1.0mm SHS @ horizontal 6mm x 19mm Solid Flat Bar - RM10.00/sf, Powder Coated add RM2.50/sf (plain colour)

Mild Steel Window Grille with outer frame 19mm x 19mm x 1.0mm SHS @ horizontal 19mm x 19mm x 1.0mm SHS - RM8.00/sf, Powder Coated add RM2.50/sf (plain colour)

want angle frame, add RM1 extra/sf

is there some kind of grille design + steel material that makes it difficult to be cut or pried open especially for windows?

stainless steel?

this looks interesting

I gess this is more for escape purpose, and is that strong to prevent breakin?
But never the less, nice concept...

Hi, anyone heard of invisible grille?

any1 actually did not use grill and uses security film for thier windows?
