Normal doors are often made of wood or metal. These doors are decorated with different colors and polished oil. MDF and solid wood are other common door materials. Anti-theft doors have a heavy steel plate inside. This steel sheet makes the weight of the door heavier than usual. Drilling a hole in the door to enter the house is one of the ways to enter it. Some thieves also break the door. Placing a steel sheet inside the door makes it resistant to breaking and piercing. Anti-theft door covers are also in different types. This cover can be wooden or metal, ceramic, mirror, wood, etc.
Another difference is the tools and fittings. Most of the anti-theft doors are equipped with accessories such as night locks, eyes and high-quality handles, or even with more advanced tools such as thermal and image sensors. These sensors increase the quality of the door much higher. The number of anti-theft door hinges is also higher than normal doors. These doors have more than two hinges and usually three hinges.
