The Process of Granite Tiles

 

Our team of experts has over 20 years of experience in the stone industry.

Step 1: Selecting the granite Blocks

The first step in the process involves selecting the perfect granite material for the desired tile design. This involves choosing the color, grain, and texture of the granite material. The selected granite block is then cut into manageable-sized slabs.

Step 2: Cutting the granite blocks into slabs

Granite blocks are cut into slabs by using multi-blade diamond saw. This is a crucial stage as the cutting process has to be precise. The cut granite pieces are then polished to make them smooth and shiny.

Step 3: Calibrate the granite slabs

In order to achieve more precise thickness, we usually use calibration machine to uniformly set the thickness of Slabs, to make sure of the consistent thickness.

Step 4: Polishing the granite slabs

This involves sanding and polishing the slabs to create a smooth and shiny surface. This step is also crucial, as any imperfections on the surface can affect the overall appearance of the tiles.

Step 5: Cutting slabs into tiles

This is mostly done by using infrared ray cutting machines. This is an essential step as the accuracy of the tiles depends on the skill of the workers and the advanced machines.

Step 6: Secondary processing of tiles

Some tiles require small cut edges or shaping according to on-site construction needs, such as bull-nosed edges, straight edges, half bull-nosed edges, back bevel edge, and other secondary processing, etc.

Step 7: Dry-laying service

Our dry-laying workshop is very large, which many factories do not have. We can conduct preliminary layout based on the construction shop drawings, and check the stone texture direction, and check whether the tile size is accurate, whether the stone surface is OK, and so on.

Step 8: Packaging and shipping

The final stage of the process involves packaging the granite tiles and preparing them for shipping. The tiles are carefully packed in strong and fumigated crates and put shipping marks for easy identification. The packages are then transported to their final destination, ready for installation.
