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 wink.gif

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  tongue.gif

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

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.

Could anyone who is currently using Top Security or New Edge security doors please feedback whether they are good? Thanks.
