Installed mine yesterday ..
Bought from Top Security - 5*7 and 3*7.

just want to ask, my front door realtively small than the standard size of security door.. my door only 80 cm width or 2 ' 6 feet ony. so how to install security door....

No choice, you have to hack the concrete around your door frame.

ussually instalation cost include this hacking the wall or not

Nope, they will only give you the dimension of the size that they need hacked, to install their frame.

any comments on using security door?
still quite skeptic using a door without grill

my contractor bought the security door but the way it open is wrong...
door shld b intstall butt by butt ma, when open the door, it shld b close to the wall...


im gonna ask him to hack n change it..duno he willing to do so onot..haih..headache .....

anyone bought fr top security recently?

how much 5x7 n 3x7 security door?

thanks in advance.

can our local security door pass test above?

if you buy a decent one they can pass.

U from jb area ? Actually I see a lot of ppl using fong yong for their back door ,my neighbour most using this brand. Looks sold and full ss

Wao...I think the price of your steel door is quite quite cheap. I got it for very high range. Can you please tell me from where you have buy this??

Guys, just a quick note. I see many people recommending some of the cheaper brands like 3k for front and back door package. There are generally a few flaws in the designs of these doors.

1. Hinge is exposed if the door opens outwards. They use normal Full Mortise Hinges. That's the type which you find on most doors. If the hinge is on the inside, it is not too bad. But most back doors open outwards and thus expose the hinges. These can be jacked fairly easily, even if they are 'seal welded'. Fully concealed hinges are the best.

2. Many do not have an all round frame. Most of the cheaper doors have to top and two sides of the frame – like a normal door frame. This leaves a gap between the floor and the bottom of the door, especially if it is poorly installed. My friend experienced this problem. He now has to use a sweeper strip along the bottom to seal from outside dust etc. The main problem here is it creates a pry point.

3. There are a number of security doors that have built in ‘grills’ where we can open a small inner panel for ventilation. To be frank, I’ve looked through many designs and brands. Some have welded in grills etc. which are better but still not ideal. The inner panels are also very weak, especially their locking mechanisms - they can be easily pushed through/punched out with not too much force. If you want a grill, you’ll need a double layer door+grill system. Unfortunately most of these incorporate both into one panel severely reducing safety. If you want ventilation, open your windows

4. Check to see that the panel of the door is from a single sheet. Many use multiple pieces welded together to optimize material consumption. Single sheet hydraulically pressed panels are the best.

Hope this helps ya’ll select

Thank you so much Neosaint99 for your explanation. Now I am more educated in selecting a better door.

Most welcomed

I was quoted full ss grade A front big small door + kitchen full ss grade A for 6100 without installation . From fong yong . Compared to new edge/top security , theirs is better cos of the high tensile properties of ss

When you say its better due to the high tensile properties of stainless steel, what are you comparing to? Generally carbon steel has better mechanical properties as compared to stainless steel, though the advantage of SS being inert is a definite plus. Its failure mode is also not as good as CS. There is no such thing as "Grade A" SS in the industry. Try to find out if it is 304, 316, 316L etc. These are the common high grade SSs (corrosion resistance, not strength).

I checked out Fong Yong's doors and from their website, they use the full mortise hinge design on all their doors. If this is true, then it should be a major concern. If they have conceled hinges, then the deal sounds better. Hope there are no 'built-in grills' too...

There are high tensile grades of SS but these are generally considered to be more exotic and I doubt they will be used in door construction. They are generally used for pipes that convey corrosive fluids under high pressures.

Grade A means 304 , grade B 2xx , the composition of Cr is lower than grade A . This is more on corrosion resistance. For comparison if u read my post I'm comparing with newedge/top security 0.9mm zinc plate which they are using. So in terms of tensile strength ss is much more superior.

Hi sifus,

During an expo, I've seen a company selling security doors, the hinges are concealed within the door frame, so when u close the doors, the hinges are hidden.

And also the door has an extra piece at the edge of the door, so when it closes, it will hide the gap between the door and frame as the extra piece would be on top of the frame.

But I forgot the company name, would anyone know the company or any other company that sells this similar type of doors?
My concern of the hinges and gaps is because, no use having such a heavy duty door, when they can easily destroy it through the hinges and gaps using a crowbar.

I am not tech savvy so what sifus mentioned here puzzles me, it will be great if sifus here can point out which company has a better and safer security door, so that I can zoom in and buy it.

Thanks.
