Processing of Natural Stones

From the beginning, nature gives us a lot in the form of mountains, air, rivers etc and demands nothing in return. Nature presents us with a number of beautiful quarries around the world. A natural stone quarry is a place from where natural stone is extracted. If nature has given such a beautiful thing, then why not utilize it to the best. Our company buys blocks from the different quarries of the world and fabricates it to make final products.

Stages or steps involve before product reaches the final customer:-

  • Extraction –Natural stone is being quarried out of mountains or underground area from all over the world. The challenge is to abstract the most quarried stone without making any damage to it. The extraction process starts by outlining a sector of the wall. The team of experts uses gas flint to make long narrow channels. Then deep holes are dug and explosive cable is feed into the holes to set it off. The explosive detaches the section. Blocks are put down with heavy machinery with due care. Giant blocks are cut into small blocks with the help of wedges. At the factory, the first cut is called slabbing.processing of natural stone, natural stone, sui usa
  • Fabrication Process –Stone is fabricated into different machines to get the finished product. Fabrication is a two-way process which involves cutting and finishes both.
  • Cut to Size – The blocks are cut to size as per customer special or customized order or as per our catalog regular sizes available in stock. After the slicing a block into particular sizes, the product is sent to different finishes.

  • Finishing of Stone Surface – Natural stone surface is available in the following finishes:-

Flamed – Bursting of crystals under high-temperature flame gives this finish to the stone surface. It provides rough texture which is slip-resistance. Thus, it is suitable for outdoor applications.

Polished – A shiny surface of the stone highlights the polish finish. It gives a mirror-like look to the stone and brings out the full color of the stone. This finest finish available in the stone is ideal for indoor applications like the interior walls or kitchen countertops.

Honed – Honed finish is another version of a polished finish. It gives non-glossy but smooth appeal to the surface. This matte surface is perfect for heavy traffic areas as it is slip-resistance.

Sandblasted – As clear from the name, a high-pressure blast of silica sand is done on the stone surface through an air gun to give it a rough texture. Small craters form with the sand work well to reflect the natural color of the stone. It is perfect for both interior and exterior, but more ideal for exterior applications as it provides more grip in wet conditions.

Short-blast – The shot-blasting process is similar to the sand-blast process to a great extent. The short blast is done on the surface and gives the natural stone an aging property. It softens the color and leaves a matte finish on the stone surface.

Thermal – A high-temperature flame applies on the stone surface to gives it a thermal finish. As a result, surface depicts crystals on the face and rough-texture. Ideal for paving applications as it is highly skid-resistant in nature.

Tumbled – The stone is processed in the vibrating machine using small ceramic stones to get tumbled finish. It generates round edges. The antique color range of SUI depicts the tumbled finish. It is perfect for the walls and floors.

  • Edging: – If sides are sawn cut, no additional work to stone is required but if sides are rock face then after the final finish to the product, additional work is done i.e. sides are rock faced or chiseled or snapped face using hammer or chisel. Wall caps, columns caps, steps, treads, patterns are available with rock face or chiseled. Great choice for exterior building cladding, landscape wall applications, fountains.

Igneous Rock: –

Also popular with the name magnetic rock, igneous stone forms with cooling and solidification of volcanic material such as lava or magma. It may form on the surface of the earth (extrusive rocks) or deep inside the Earth’s crust (intrusive rocks).

  • Granite: – Granite forms through the crystallization of magma underneath the Earth’s crust. Quartz, plagioclase feldspar and alkali feldspar all together helps in composing of a true granite. This light-colored igneous rock is granular and phaneritic in texture whose color may vary depending on its mineralogy.Aberdeen in Scotland constructs principally from the granite and known as “The Granite City”. It suits well on the countertops, stair treads, driveway cobbles, wall panels, patios, fireplaces, building veneer.
  • Basalt: – Basalt is volcanic stone form through the rapid cooling of basaltic lava. It has fissures and small holes on its surface. Most of the basalt quarries are available in the states of East Asia. The dome of Pantheon, Rome constructs from Basalt. It is suitable for countertops, paving, wall cladding, driveways.
  • Porphyry: – Porphyry is a fine-grained igneous rock mainly consists of crystals of feldspar and quartz. Porphyry plays an important role in the construction of Mosque of Cordoba, Spain. It is perfect for walls, outdoor kitchens, paving.

Metamorphic Rock: –

Metamorphic rock is the outcome of metamorphism process which refers to the change occurs in the pre-existing rock due to heat, pressure. As a result, these are more solid than the pre-existing substance.

  • Quartzite: – Quartzite forms after the conversion of quartz-rich sandstone under the tectonic compression by the process of metamorphism. It makes this stone hard and non-foliated. A historical federal office in the U.S. the Courthouse, Sioux Falls constructs with quartzite. It suits well on the countertops, pool surrounding, pool deck, kitchen, bathroom, patios, exterior-interior wall cladding.
  • Slate: – Shale-sedimentary rock (compose with volcanic ash and clay) is put under the heat and extensive pressure to form a slate stone. It is fine-grained and foliated in its nature. The Guildhall in Landon and Saint Leonhard’s Church in Germany protects roof with slate stone. It looks good on the stairs, patios, pool surroundings, pillars, walls, windows, countertops, walkways, and gardens.
  • Marble: – Re-crystallization of carbonate minerals, especially calcite or dolomite helps in the formation of marble. Marble is a common product for making sculpture and buildings. Dome of the Rock, Israel and Taj Mahal, Agra construct with marble. It is perfect for Mosaics, bathroom, fireplaces, stairs, countertops, entryways.

Sedimentary Rock: –

The formation of this stone is a result of subsequent cementation and deposition of organic elements such as wind, glaciers, plants, rivers, and oceans. Sediments (small organic particles) are set in a place through sedimentation process.

  • Limestone: – Skeletal fragments of marine organisms like coral, forams, and mollusks lead to the formation of limestone. Comprises mainly of calcium carbonate (CaCO3) and form due to the breakdown of rocks and shells. The white town of Landon constructs with limestone. People adopt it to accent walls, pool surroundings, fountain, stairways, windows, kitchen countertop, façade, bathroom, sidewalks, driveways, patios.
  • Sandstone: – Sandstone consists of mineral particles (quartz and feldspar) and grains of rock fragments which are the most resistant minerals to weathering processes. Red Fort & Qutub Minar in India, the part of UNESCO world heritage sites are the proof of the beauty and durability of sandstone. It is perfect for walkways, flooring, and facade. It can as a veneer for the pillars or walls cladding also.

  • Travertine: – Pitted holes and troughs on the surface of the natural stone is the recognition of travertine. Its formation takes place due to the precipitation of calcium carbonate when deposit by mineral springs, especially where there is a waterfall or hot springs. Most of the travertine quarries are there in the countries of the Middle East, North America, South America, and East Asia. Tonto Natural Bridge is the largest natural travertine stone bridge in the world. It is perfect for paving, garden paths, facades, wall cladding, bathroom flooring, kitchens, outdoor spaces and for decorating walls.
