What is granite? Introducing the types of granite and its uses in construction

Granite is one of the most resistant and durable building stones. In this article, you will learn about the types of Iranian granite, its features, advantages, disadvantages and uses in construction.

What is granite?

Granite is an internal igneous rock that is formed by the slow cooling of molten masses deep in the earth. This stone is one of the best options in heavy construction projects due to its high density, excellent resistance to pressure, scratches, abrasion and heat.

Granite is made of a combination of quartz, feldspar, mica and various minerals, and for this reason it has coarse-grained designs and various colors.

Features and Benefits of Granite

Important Features of Granit

• Very high strength against impact and pressure
• Excellent resistance to abrasion and heavy traffic
• High thermal resistance (suitable for kitchens, laboratories, exteriors)
• Very low water absorption
• Very long life

Advantages of Granite

• Suitable for high-traffic areas such as parking lots, stairs, and flooring
• No discoloration from sunlight
• Easy to maintain
• Excellent sandability

Disadvantages of Granite

• Heavy weight
• Higher price than some other stones
• Less variety of colors than marble and travertine
• High hardness (takes more time to execute and cut)

Applications of granite stone in construction

Granite is used in large and small projects due to its high resistance:

1. Interior and exterior flooring

• Complex lobbies
• Shopping malls
• Airports, subways, public spaces

2. Staircases and treads

Due to its resistance to impact and heavy traffic, it is an ideal choice for stairs.

3. Exterior facade of the building

Granite does not change color in sunlight and rain and is one of the most durable options for facades.

4. Kitchen cabinet and island

High heat resistance and scratch resistance make it a suitable option for the kitchen.

5. Paving areas and sidewalks

Granite is the best option for areas with high pressure and high traffic.

6. Tombstone

Due to its durability and uniformity, it is also produced in large sizes.

How is the price of granite determined?

The price of granite depends on the following factors:

• Type of quarry and color of the stone
• Degree of quality and uniformity
• Thickness (2, 3, 4 cm)
• Sanding and polishing
• Dimensions (slab or tile)
• Cost of extraction and transportation

Rare granites such as Natanz Black or Gabbro have a higher price.

Conclusion

Granite is one of the most resistant and durable building stones produced in Iran with a variety of colors and qualities. If you need a durable, economical stone with a long lifespan for large projects, high-traffic floors, stairs, cabinet tops or exteriors, granite is one of the best options.
