With steel security doors tests on their strength are an industry requirement. These tests guarantee buyers that steel doors cannot be broken into in such a manner.
First, let's look at what they are. Unlike a regular wood or standard UPVC door, composite doors are formed from several materials. The inner section is usually foam for insulation, while for the outer skin you can choose from aluminum-steel, UPVC, or glass reinforced plastic (GRP). The latter material is very popular nowadays owing to its many intriguing properties that make it perfect for use in doors.
Other than the inner foam, these doors have other insulating enhancements in the form of high efficiency sealing systems to further keep out sound and the elements.
