Happen to come across this somewhere recently
Price RM/ sg ft

MS Door - RM 10
MS Window - RM 7
Wrought iron Door - RM 18
Wrought Iron Window - RM 11

I think he meant if for mild steel window, it will be RM11 - 4 = RM7 &
for door will be RM 16 - 5 = RM11

The hollow MS grill should be around RM 8 -9/ft2. This was the rate given to me by 3 contractors.
As for the wrought iron type, I don't have any info as I did not go for this.

If your alarm coverage include the ceiling, then the ceiling manholes would be secured by the alarm. If the burglar really want to enter your house, they could just easily break the ceiling. No need to locate your ceiling manhole.
But since your contractor is giving them FOC to you, why not take it. Additional protection.
But, bear in mind that having the grille at the ceiling manhole will not look nice, in my opinion.

Grille is the bathroom are subjected to moisture from the shower. Especially if you use the hot water frequently. Since you need the protection, why don't you get the contractor to put additional coating onto the grille before installing.
Get them to put a good primer before putting the finishing paint. Primer is important.

Equally important to ensure that all the gaps at the joints are fully seal up. This is to prevent the moisture from entering into the inside of the hollow sections, thus forming rust from within.

Why do you want to keep those additional ceiling manhole grille?
Might as well ask for discount. If cannot, maybe get him to put additional coating on those bathroom grilles.

You need space to keep the manhole grille

If you are trying to reuse the grilles previously for window frames onto new aluminum windows, there is bound to be problems with the dimensions. Modifications are more labour intensive compared to totally new ones.
End of the day, if the modified grilles does not fit nicely onto the new window frame, who will be responsible? The grille make will not want to take responsibility and the owner will not accept.
Don't think there is any grill maker will take up such risk.
Most likely, they will propose that you make new ones.
They will take the exact measurements after the windows have been plastered.

If at the end of the day, after (accurate ) plastering around the windows frame and you find that there is still some gap between the plastered edges and your existing grille, you could opt to either add a flat bar around the edge of the grille to hide the gaps (that's what I did for mine) OR you could fix some trimmings/ Architrave (timber, etc)around the grille frame.

No way the RM1,690 would include the auto gate system
The auto gate system itself already cost more than 1k, depending the model you are installing

My contractor charged me RM2.4k for similar size and design, galvanised gate incl stainless steel track.

My gate size is 6' x 15'

The outer frame is of 2.3mm while the inner steel sections are either 1.2mm or 1.6mm. The reason for this is because my gate was galvanised. There is a minimum thickness of steel sections if you are putting them through the hot dipped galvanising process.

BTW, I have know the fabricator a long way back. Thus, could be the reason for the special price.

If you are going for galvanising, then there is a minimum thickness for different member sizes. Of course, the thicker the steel member, the better BUT don't forget the weight consideration especially for the gate. As the thicker steel members will add on to the overall gate.

16' would be better. That was also my initial plan. But due to the need to allocate the space for the rubbish compartment and water filter, plus the gate pillars, etc. I am left with balance of 15' plus for the gate. 15' is still OK if your dive way is long. If your driveway is short (just enough for the length of your car, then it could post a problem. Another issue is the type of gate used. If using the folding gate, you need to allow for the effective clear opening. The type of auto gate system also effects the effective opening. Those using the arm type will have a smaller effective opening.

This kind of anchor quite common and very cheap. Easily obtain from all hardware shops. Will not cost more to use them. Most important is to tack weld the ends after fastening

Powder coating is more for the aesthetic while galvanising is corrosion protection. Both function differently

ic that you have now become a galvanising expert

1. Powder coated mild-steel price.  He said normal (non-powder coated) = RM10/sqft.  Powder coat must send to factory - must check back price.  Anyone know what is the price range like? Powder coating is done by specialist. Not every grill fabricator will have that.
2. Sleeve anchor.  He said he use wall plug (plastic) and screws only. Also OK la... if you are fixing the grille on the inside. Just try to cover up the screw so that it would be difficult for anyone to unfasten them.
3. Weld nut after fasten on sleeve anchor.  That won't damage powder coating at the bracket? Could always protect the rest of the parts during welding
4. 1.2 mm vs 1.6 mm.  Dunno about 1.6 mm.  Regular one 1.2 mm only.  Anyone have 1.6 mm thick grille? Price will be dependent on the material thickness. Reckon, for window grille, 1.2mm should be more than sufficient

Do you mean that you do not intend to lock the small door or what? Don't understand.

Check out the available lock set that suits your requirement. There are some that needs the key to lock, etc...
