Gangsaw Slabs vs. Cutter Slabs: Key Differences

Gangsaw Slabs

Gangsaw slabs are large-sized granite slabs cut using gangsaw machines, which operate with multiple parallel blades. These slabs are typically used for applications requiring seamless and expansive surfaces, such as large countertops, flooring, and wall panels. Due to their size, gangsaw slabs provide more design flexibility with fewer joints and uniform patterns.

Standard Sizes of Gangsaw Slabs:

  • Length: 2600 mm to 3200 mm
  • Width: 1600 mm to 2200 mm
  • Thickness: 15 mm, 18 mm, 20 mm, 30 mm, and customized thicknesses

Gangsaw slabs are commonly used for premium interior and exterior projects, ensuring a luxurious appearance with minimal seams.

Cutter Slabs

Cutter slabs, also known as mini slabs, are smaller in size compared to gangsaw slabs. They are produced using block cutters, which are more compact and versatile than gangsaws. Cutter slabs are mainly used in flooring, staircase treads, and small countertop projects.

Standard Sizes of Cutter Slabs:

  • Length: 1800 mm to 2400 mm
  • Width: 600 mm to 900 mm
  • Thickness: 15 mm, 18 mm, 20 mm, and 30 mm

These slabs are more cost-effective and manageable, making them a preferred choice for residential and small-scale commercial projects.

Thickness Options for Polished Granite Slabs

The thickness of granite slabs plays a significant role in determining their durability, application, and cost. Here are the most commonly available thickness options:

  1. 15 mm – Lightweight and economical, mainly used for wall cladding and interior applications.
  2. 18 mm – Standard thickness for countertops, flooring, and moderate-load applications.
  3. 20 mm – The most preferred choice for kitchen countertops, vanity tops, and commercial spaces.
  4. 30 mm – Extra durable and ideal for heavy-duty countertops, staircases, and high-traffic areas.
  5. Custom thickness – Can be tailored based on project requirements, often used for architectural facades and monuments.

Finishes Available for Polished Granite Slabs

A matte, smooth surface that offers a softer, elegant look. It is commonly used in bathrooms, wall cladding, and areas where a less reflective surface is desired.

A textured, slip-resistant surface with a subtle sheen. Leathered granite is ideal for outdoor countertops, walkways, and commercial spaces.

A heavily textured finish achieved by mechanical hammering, adding a rustic and rugged look to the stone. This finish is widely used in landscaping and public spaces.
