Natural veneer stone products

Natural veneer stone products are natural rock by mining, cutting, polishing and other processes and become, because of its unique decorative is used as a more high-grade decorative materials, natural veneer stone classification is mainly based on the hardness of the stone, divided into: granite, marble, stone and so on.

Natural veneer stone

(1) Granite plate.

Granite plate is granite through sawing, grinding, cutting and other processes and become.Granite plate quality of a material is hard and dense, compressive strength is high, have excellent wear resistance and good chemical stability, not easy weathering metamorphic, durability is good, but quartz is contained in granite stone, crystal transformation can be produced below high temperature, produce volume expansion, accordingly, granite fire resistance is poor.

Granite is different according to its use, its processing method is different also.Defeathering boards commonly used by builders, mainly used in outdoor floors, stairs, pedestals, etc.Half of the planer plate is used on the ground, step, cornice, steps and so on;Granite coarse grinding board is used for wall, cylinder, monument, etc.;Polished plate because of its specific bright color, good luster characteristics, mainly used for indoor and outdoor wall, ground, cylinder, etc.

(2) Dali SLATE.

The main technical requirements of the marble plate are: size allowable deviation, appearance quality, mirror gloss, volume density, water absorption, dry compressive strength and bending strength.

Marble plate is used in hotel, exhibition hall, cinema and theater, shopping mall, library, airport, station and other public building projects of interior cylinder, floor, window sill, service desk, elevator door face, is the ideal interior senior decoration material.In addition, it can also produce marble murals, handicrafts, daily necessities and so on.

Marble plate has the advantages of small bibulous rate, good wear resistance and durability, but its anti-weathering performance is poorer.Because marble main chemical composition is calcium carbonate, be eroded easily, make the surface loses luster, become coarser and reduce adornment and use effect, reason divides individual variety (contain quartz to give rise to sandstone and stone cramstone) outside should not be used as outdoor adornment generally.
