HOW TO EXTRACT DURO ROOFING SLATES
Our slates are originally extracted from deposit at foot of Lushan Mountain. Unique geographical location and pressure make the slates finely grained. Modern facilities applied and hand splitting into required roof slates.
1. Quarry where raw stones come from
YIGROUP Slate ' s quarry is located at Jiujiang Jiangxi where is one of highest quality slate deposits and beds in China. Our quarry is an open quarry and the slate is extracted in large blocks cut with a diamond blade and jackhammers. The blocks are then transported by trucks to the quarry fabrication plant.
2. Slate fabrication processes
© Cutting to blocks: The large slate blocks extracted from the quarry are cut into thick blocks with same length and width of the final slates be produced.
© Splitting to pieces: Experienced workers split each block into pieces with thickness twice of the final slates, then these pieces are then split in half to required thickness.
© Trimming or beveling the edges: The cut edges of each slate are trimmed or beveled in order to facilitate the passage of water over the slate once in place on the roof.
© Drilling and further fabricating: The methods of slate roof installation are developed, such as nail fixing, hook and aluminum profile, drilling and further fabrication on slates can be optionally done.
3. Packing and shipping
The selected slate tiles will be packed with fumigated crates and stored before shipping. Professional couriers and logistic staffs will handle all shipping affairs to your local seaport.
