Granit external staircase - The advantages
Granit is an extremely robust material, weatherproof and easy to clean. These advantages make a granite exterior staircase insensitive to temperature changes from frost in the winter to the summer heat. This ensures a decades-long service life if the stairs are laid correctly.
Granites are usually medium to coarse-grained. They have an uneven mineral distribution without grain or structure. This gives them a relatively uniform appearance. The main components of granite are quartz, feldspar and mica. The color spectrum of a granite exterior staircase ranges from light gray to greyish-bluish, red and yellowish.
Granites are one of the most abundant natural stones in the world and can be found all over the world. The most famous granite deposits in Europe from which material for granite external stairs is obtained are in Spain and Italy.
Natural stone entrance stairs must be non-slip.
The surface of natural stone entrance stairs must be sufficiently slip-resistant, so that the stone staircase can be safely used even in rain, ice and snow. For this reason, natural stone exterior stairs in the tread area should always have flamed surfaces.
Flamed surfaces are created by a strong heating of the stone surface with an extremely hot gas flame, which leads to small flaking of the quartz in the rock surface, without damaging the inner structure of the natural stone. This gives the natural stone exterior staircase the necessary roughness.
