WHAT IS NATURAL SLATES? Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism. It is the finest grained foliated metamorphic rock. Foliation may not correspond to the original sedimentary layering, but instead is in planes perpendicular to the direction of metamorphic compression. A very strong foliation is called "slaty cleavage". It is caused by strong compression causing fine grained clay flakes to regrow in planes perpendicular to the compression. When expertly "cut" by striking parallel to the foliation, with a specialized tool in the quarry, many slates will form smooth flat sheets of stone which have long been used

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.

TESTIMONIALS
“ “
The slates are arrived with good condition and the quality is excellent as always. They have been installed and satisfy our client very much. More business will come soon. ---George Senior roofer
I went to see the roof we are doing with the 400 x 400 Grey slates last week and it looks really well and the client is very happy. It gives a very rough looking finish which this client likes. I will send you some photos so you can see for yourself. We are very happy and look forward to ordering more soon. --- Randal
“
I must say your slates are superior than ones we currently buy from Shaanxi and we are willing to list you as our future roofing slate supplier and recommend you to house owners, trust me our first trial order will be placed very soon. --- Simon Hardy, Roof maintenance and contractor

SLATE ROOFING
A typical slate has a top, bottom and two sides. The top of the slate is known as the ‘ head ‘ and the bottom the ‘ tail ‘ , the head sits on top of the roofing batten and the tail sits on top of the slate beneath it. If the slate is not a uniform thickness the head is normally the thinner end and the tail the thicker. The front of a slate will display riven ( bevelled ) edges on all sides and this is called the ‘ face ‘ , and the underneath is the ‘ bed ‘.
