Thank you for your feedback.

Tell them if no need pay then come install lah.

Modify, not many will do cause is labor intensive. I got a friend asking many to mod come of the grill, but no one want to do it. End up i think he rent welding machine and do it himself.

Lots of way to sell cheap. Use thin metal, difference grade metal, type of paint.

Normally Galvanised is done by specialized factory. Grill maker will send it to the factory and do.

1.6 and 1.2mm, you mean thickness? 1.6mm is better.

If is weld is ok. For outdoor try use galvanized.

Maybe he don't do Galvanized. Proper galvanized metal, it can last long for welded portion need to use good primer + paint (or even some paint now are very good to protect rust) will do.

Not as strong as galvanized.

We never see lamp post rust right is galvanized.

FAQ Galvanized


1. How does galvanizing protect steel from corrosion?

Zinc metal used in the galvanizing process provides an impervious barrier between the steel substrate and corrosive elements in the atmosphere. It does not allow moisture and corrosive chlorides and sulfides to attack the steel. Zinc is more importantly anodic to steel – meaning it will corrode before the steel, until the zinc is entirely consumed.




4. How long can I expect my galvanized steel project to last in service?

Hot-dip galvanized steel resists corrosion in numerous environments extremely well. It is not uncommon for galvanized steel to last more than 70 years under certain conditions. To get a good idea of how long your project will last, see the service-life chart.

No lah.

Uncle google help, and some friend also using it.

1. Think is only extra RM 1 or RM 2 only.

2. Yup, normally use wall plug and screw down, than weld and grind off the top. Than paint. Only door they use sleeve anchors, than cut and weld after secure.

3. It won't cause usually the grill have extended ear, and the nut are bolt on the ear.

4. I think you need 2" or maybe 2.5" steel to get 1.6mm. Mine 1" is also 1.2mm maybe 1.1mm not too sure.

I'll advice if you want powder coat, get common color so is easier to patch by normal paint. I am using normal matt black powder coat internal, external is galvanized + paint over it using same color.

It still easy peel off, maybe harder only. My grill is a good example, drop some hardware on it, one patch came off. Lucky is common color, I apply primer and spray it.

Rough surface is it what you'll refer to paint in matt finish?

My entire house with 13+ feet metal gate around 10k, external is with hot dip galvanized.

I see you have 3 unit sliding door, that usually more expensive. And you did not state the measurement is also very hard to give you advice.

No lah. Is about market price.

But I think that company too rich already. Install everything about 3 weeks already don't want to come collect the balance 70%.

Yes, is all about money. Or ask them use 20mm diameter Rebar

You need to have solid support the normal sand brick may not hold the weigth.

Not sure, is all about design, and also thickness. You need to ask them for quote. The price of steal is really sky high now.
