All About Granite Slabs

Stone slabs are pre-processed slabs, the length of which is approximately 3000 mm, thickness up to 40 mm, width up to 2000 mm. If a special order is received, slabs can be made to individual sizes. The main raw materials are marble, slate, onyx, travertine and, of course, granite.

The stone does not become a finished product immediately; the transformation process begins in a granite quarry. Blocks are extracted from the massif of stone, and then they become those very slabs. These are versatile plates of large sizes, from which many things can be made. For example, they make sawn granite paving stones, facing tiles.

The blocks delivered from the granite quarry are sent to production. Before sawing them, it is decided for what purpose this particular material, what will be produced from it.

Slabs are cut with circular saws either on stationary machines or with bridge equipment. For cutting, discs with diamond dusting are more often used, and the cutting depth is limited by the radius of the saw blade (it can reach up to 150 cm). It is not excluded the use in production and cantilever structures with several discs on the shaft at once. For productivity, this is a huge plus, there is also a disadvantage: the range of variation of the distance between the saw blades is not particularly large, which limits the thickness of the products produced.

There is another way of processing slabs, a more modern one: we are talking about cutting slabs with diamond wires. The machines operate on one or more ropes. This equipment is expensive, but it is very valuable for working with slabs - energy consumption is low, cutting speed is high, blocks of any size can be cut, water is consumed much more economically during sawing, the cut itself has a small thickness.

Slabs are processed as follows:

• Grinding. It occurs on machine tools using abrasive wheels. The surface becomes slightly rough, the products acquire anti-slip properties. Finally, the color and pattern of the stone becomes more expressive.
• Polishing. The slabs are processed with powder-coated wheels and a felt layer, which gives the product a special shine, reveals the natural structure of the stone and color.
• Heat treatment. Thermal gas jet machines are used, which creates the effect of peeling and melted material. This is an excellent option for finishing facades, stair steps and other architectural products. It is necessary to emphasize the decorative characteristics of granite.
• Bush hammering. Special "hammers" form noticeable irregularities on the stone, which have not only a decorative function, but also the function of preventing the surface from slipping for safety reasons.

Granite is a massive and very durable stone that belongs to igneous rocks. Its structure is such that granite can be used both as a material for future elegant products and for huge interior elements. The beauty of granite is that mica, quartz and ortho-eye are mixed in it.

Granite slabs are always rectangular in shape. Sizes are:

• from 1.8 m to 3 m on the longest side;
• 0.6 to 2 m on the short side.

Granite slabs also differ in color: gray, blue and dark red are more common, but black is less common. But absolutely all granite slabs are distinguished by excellent frost resistance, durability, good pliability to grinding and toning. Chips and cracks rarely appear on this stone.

Slabs are a blank, that is, an intermediate form of the material. But from this blank, you can cut virtually any architectural detail, interior element (even a very large one). Slabs are used as a whole, if you need to tiled floors, walls, finish the bottom of the pool.

In the interiors, bar counters made of granite slabs, pedestals, countertops, and columns are common. Parapets and cornices on building facades can also be made from these blanks. If these are heat-treated slabs, they are usually used for either facade cladding or paving materials. Polished ones are often used for interior decoration. Granite window sills turn out to be interesting: a solid, massive, very beautiful independent interior element.

If the kitchen is large, then you want to choose the appropriate set for its size. In this case, the granite slab countertop will be a worthy embodiment of the idea. In addition, such an acquisition will not need to be changed after 5-8 years - the granite countertop will last much longer.

Granite in architecture, construction, design is absolute environmental friendliness, graceful decorativeness and majestic monumentality. That is why such a solution is classical (out of fashion and time).
