| Production Requirements:(Slabs,Cut-to Size,Tiles,Floor& Wall Cladding)
A.Specification
(a)Random Big Slabs:
2400X1200mm up in various thickness over 18mm(Such as 20mm,30mm,40mm etc)
(b)Cut-To-Sizes:
300X300mm/300X600mm/400X400mm/500X500mm/600X600mm/750X750mm/800X800mm/900X900mm... in various appointed sizes
(c)Random Strips & Small Slabs :
thickness over 10mm in length over 1500mm & height over 600mm,(Such as 1800mmupX600mmup,2000mmupX600mmup,2400mmupX650mmup,and other special 1800mmup-3000mmX600mm-1000mm, etc)
(d)Surface Finishes:SAWN/POLISHED/HONED/FLAMED/WATER-JET/SANDBLASTED
Waterjet: a non-slip matt finish, produced by working the surface of the stone with high-pressure water jets.
Honed: a smooth finish with a slight sheen, produced by using a polishing head.
Sandblasted: sawn stone slabs are coarsely polished: this removes saw marks and leaves a semi-smooth, regular finish.
Flamed: the top surface of the slab is burnt off, giving an irregular textured.
* Tiles: Polished/ Beveled/ Calibrated,Flamed/ Calibrated
300x300x10mm / 12x12x3/8" (305x305x10mm) / 12x12x1/2" (305x305x12mm ) / 12x24x3/8" (305x610x10mm)
400x400x12mm / 16x16x3/8" (400x400x10mm) / 18x18x3/8" (457x457x10mm)
B.Quality Control Standard :
Granite should be grade A quality, and the finish as follows:
Polishing:
Polishing will be uniform throughout the slabs/tiles and in glossometer as:
For black slabs / tiles : polishing +95 in glossometer
For colored slabs/ tiles : polishing +85 in glossometer
There should be no grinding wheel marks on the polished face.
Flaming:
Flaming will be uniform throughout the slabs/tiles and brushed evenly on slabs after flaming
Thickness:
+/-1.0mm in tolerance for slabs; +/-0.5mm in tolerance for tiles
Diagonal Out:
+/- 0.5mm in tolerance for tiles
Flatness:
If length <= 400mm,flatness tolerance: +/-0.2mm
If 400mm < length < 1000, flatness tolerance: +/- 0.5mm
If length >= 1000mm, tolerance: +/- 0.8mm
Length And Width:
+/- 0.5mm in tolerance for tiles and slabs (not apply to the random edge slabs).
Front Edge Defect:
Not allowed for slabs and tiles.
Front Corner Defect:
Not allowed for slabs and tiles.
Unpolished Side:
The unpolished side of the slab/tiles should be flat and smooth.
Crack:
Not allowed for slabs and tiles.
Crack Looks Treatment:
If slab/tile have crack looks (not the real crack, like paper been foddered but not tear down), please treat it.
Surface Treatment:
If it is possible, treat the slab/tile surface after it has been polished. So there is no little dent. This treatment is not required, but is recommended.
Billed Area Defenation:
For slab size > 1.2m x 2.2m, there should be a 1" (2.54 CM) allowance on each side of the slab to be taken out for the actually billed area.
C.Packing
(1)Tiles are packed in styroform boxes (carton boxes) and are further packed into wooden crate. Polythene wrapper is made to cover the entire material inside the wooden crate. Wooden Crate is fixed and tightened by iron strips.
(2)Slabs are well packed in wooden bundles with polished face to face.

Stone Character:
The characteristic of nature stone
The nature stone is one of the building materials that mankind used at the earliest stage. The wonderful color in surface and rock evolvement become much more noble, bright texture by the design of the architecture
Nowadays, more and more people try applying the rich color and plentiful vein to ameliorative city in monotonous landscape. For example be affixed in the stone concrete construction, or be affixed in the arched door and so on.
General characteristic.
For the nature stone,the use of the physics material is more often,but the chemistry analysis is useful too. Such the examinatio to the some harmful oxide.For example:
In the big industry city of the eastern of the United States, the pollution of the air is serious, even through the surface granite will suffer to erode.
How to choose the material becomes much more inportant.The stone which contain the easily oxidizing material will be forbid to use.Such as the yellow iron mine, will born the stain, change colors or decay.
Some physical characteristics are as follows:
The strength of anti- presses PSI( Kgs/ cm2) absorbs water rate the degree of hardness( Toughness Index)

Stone Maintenance:
Stone maintenance
Stone exposed in the air or used for a period of time. It would be come out many phenomenas as follows:
Yellow spot, the rust spot, white phenomenon - white thing run off, oil spot, salt spot, coffee etc.
Pure method:
The physics washes and the chemistry washes are the common ways.
The physics washes is too expensive because it need the related equipments.So it often use chemistry method washes.
1.sour cleaning: hydrochloric acid, sulfuric acid, nitric acid, lemon acid,grass acid etc of the inorganic acid uses. But it almost not to use it. because the inorganic acid will remain a little acid. It bad for carbonate stone material, so it should use organic acid more.
2.alkali cleaning: It is main to acidities infectant.
Protection method
It does not avoid to be dirty greasy and other phenomenon after being used.
How to maintain it?
Wash method: Wash with the neuter detergent and the soft things.
Protection method: It should use the high permeates protection to wash. This product can completely seep into the iner stone and clos the sligh hole, attain to prevent the infectant things into, and the most important is to use the surface protection at the last. It will be reach to the best protective effect.

| Installation methods of dry hang up： |
|
1.Drill on the wall, so that the bolt can be installed.
2.Put the bolt into the hole, insure the planes and perpendicularity.
3.Fix-up the dry hang up unit transitorily, adjust the bolt to correct place.
4.Drill on the side of the Crystallized Glass Panel. Pay attention to the place of the hole.
5.Pour the glue water into the hole of minicrystal stone.
6.Put the minicrystal stone into the hole and install the stone slab, make sure the planes and perpendicularity and fix-up.
7.Fill in the strengthen material around the wall and dry hang up unit to firm them all.
8.Fill in the glue water.
