What is Prefabricated Granite? | Explained

Prefabricated granite, or “prefab” granite, refers to granite countertops that are pre-cut and pre-finished in a factory before being shipped for installation. Unlike traditional slab granite, which is sold in large, raw pieces and requires on-site cutting and finishing, prefabricated granite is a hassle free alternative, designed for quick and easy installation with minimal adjustments.

Granite is a popular choice for countertops amongst buyers due to its durability, aesthetic appeal, and natural beauty. Among the various options available, prefabricated granite has emerged as a convenient and cost-effective alternative to traditional slab granite. This article explores what prefabricated granite is, its features, benefits, drawbacks, and compares it with custom-cut granite.

Manufacturing Process of  Prefabricated Granite

Prefabricated granite is crafted from natural stone, with certain fabrication processes prior to shipping. This mass-production approach lowers manufacturing costs, making it a more budget-friendly alternative to custom-cut slabs. The production of prefabricated granite involves the following steps:

Extraction: 

The first step, extraction involves granite being quarried from natural stone deposits around the world.

Cutting: 

Next, large granite blocks are cut into manageable slabs using advanced machinery.

Prefabrication: 

After cutting, the slabs are then cut to standard sizes, polished, and finished with edges (often a bullnose edge) before being packaged for shipping.

Packaging:

The packaging of prefabricated granite is a crucial aspect for ensuring its safe transportation. It involves the following:

• Pallet Packing: Granite tiles are arranged on wooden pallets with polished sides facing each other, which are separated by soft paper or polythene to reduce friction.
• Wooden Crates: Tiles and slabs are packed in fumigated wooden crates which are secured with iron or plastic straps to prevent movement and damage during transit.
• Cushioning Materials: Foam, thermocol, or polystyrene sheets are used to protect surfaces from scratches and moisture.
• Marking: Each crate is labeled with essential details like material type, dimensions, and quantity for easy identification. 

Shipping: 

Finally, the prefabricated granite is transported to retailers or directly to customers, ready for installation.

This flexibility ensures that our countertops can seamlessly fit into various designs and applications, from residential kitchens to commercial spaces. Whether you prefer a sleek modern look or a more traditional style, our customizable options enable the creation of unique surfaces that enhance the aesthetic appeal and functionality of any environment.

The standard dimensions for prefabricated countertops are 112 inches x 26 inches x 0.78 inches (20mm). Although it may seem unusual to mix imperial and metric measurements, the thickness of the prefab granite is precisely 20 mm, or 2 cm. 

Flat-finish countertops with a thickness of 2 cm feature a 1.5-inch laminated flat edge on one long side and both short sides. 

For kitchen counters and bathroom vanities, backsplashes in matching granite are available at a height of 6 inches.
