Garage doors are normally made out of aluminium, steel, PVC, GRP or timber/wood. The price of timber varies massively dependent on the species you choose. Most commonly used are larch, oak, hemlock and cedar wood. Timber is very versatile and has a huge variety of designs to suit your taste.
When you are looking for overall performance and are considering strength of door, steel is the suggested material. Selecting the sectional style door, you can have double skin panels (up to 45mm thick) which give additional strength and insulation to your door.
Aluminium is usually used for roller style garage doors and a couple of specialised sectional doors.
GRP is also very versatile, but beware of cheap sellers as these can have very little material in them, which will affect the strength and durability.
Choosing the right mechanism for your garage is incredibly important, don’t just go on style! The type of mechanism you choose (sectional, roller, canopy, side-hinged etc) should actually be decided based on the area inside and outside your garage. For example a narrow garage will have limited space near the entrance so a roller door would be best suited.
