3 QUESTIONS NOT TO ASK WHEN BUYING A STEEL DOOR
* How much does this door weigh?
It is generally the first question we ask when buying a steel door: but it is a wrong question. Doors weight is majorly the result of wooden or MDF planes mounted on both surfaces of the door: therefore, the weight mentioned here will not be realistic.
It is adviseable to care about a steel door’s technical features than its weight.
* Is it possible for a buglar to break down this door?
This is also a commonly asked question which puts the seller in a very difficult position. If he says ‘yes’, he may not be able to sell the door; but if he says ‘no’, it may not be true. What is important here is that the door should be technically resistant. The higher the quality of the door you purchase, the longer it will take to break down your door.
* How thick is the door leaf?
While thickness of a steel door used to range between 45-50mm, it is much thicker now. This is actually a technique used in safe boxes; in other words, it is an illusion. It just looks safer but it is hollow. It also does not cost company high enough to influence door prices. It is even advisable to avoid too thick door leaves as the broader you make the door leaf, the broader you will need to make between the door leaf and the steel case; which will enable tools such as levers or chisels to move with much ease in this space.
