Slate from SAMACA
Manufacturing and production slate.
Have you ever wondered where and how is slate? From the pit to the roof or the facade of Your house slate tile goes a long way. The production process is more manual work than mechanical, which You ever could have imagined.
Step-by-step production of roofing slate , or as they say slate shingles.
1. Before shale tile experts-geologists conducting a lot of surveys and sample testing of the breed to learn the best areas for extraction of slate. The extraction of mining deposits begins only when is verified the quality and purity of shale meets the standard.
Shale rock is sawn into large flat plates with diamond beads on a steel cable. The machines are installed on rails which allow you to move them while maintaining an adequate length and tension steel cable, for efficient sawing of the block.
Then the plates carefully cut into smaller natural slate blocks, loaded into trucks and transported to the factories near the quarry. The transformation process begins.
3. Factory cutting.
Blocks of slate are selected according to their quality and capacity on the part of the production team and cut into different sizes.
4. The next step is the formation.
Then the smaller blocks are split manually by skilled artisans on a plate with a given thickness, one after the other.
This stage of processing slate tiles the most important and time-consuming, likely much more time consuming than You might imagine.
5. Mechanical processing of slate. When performing this operation, the shale plates gives the final shape and size.
Beveled edge slate prevents the penetration of rainwater when the wind is strong and also promotes the directed drainage of precipitation into the drainage system.
Once the process is completed, the slate passes the final inspection, and sorted by quality.
After categorization, slate tiles are counted and Packed in wooden pallets for storage and subsequent delivery.
Marking slate is applied to each pallet with a description of the slate (origin, format, thickness ...)
