The Key Point of Curved Staircase A well-designed curved staircase offers much more than its functional purpose. In fact, a staircase is an integral facet of design, a focal point, and often the first piece of furniture seen by visitors. Beautiful and complex, curved stairs are considered the pinnacle of stair craftsmanship.1.Technique DifficultyThe technical difficulty of the stone curved/ arched staircase is indeed the process of the cover plate, base plate and handrail which neither the software nor the experienced master can make it accurately. 2.Process DifficultyThe maximum they can do is to draw the length of the inner/outer arc as well as the altitude. Before processing, it still need to be adjusted ceaselessly according to the computer wire cut machine and rotary platform machine.

The traditional stone wetting installation is simple, easy to operate and low in cost. It is still widely used in stone installation projects. Therefore, it also brings a lot of stone disease after installation, the most remarkable phenomenon is stone water spots (stains) after drying for a long time. This question is plaguing many owners, construction units and stone suppliers.We will be analyzed the cause of the water spots (stains) we have encountered in our work. Firstly, different stone varieties. The stone that does not dry with water spots (stains) is mostly light-colored stones, and most of the granite stones. It is characterized by medium-acid magmatic rocks, high degree of crystallization, abundant micro-cracks between crystals, high water absorption, and high content of various metal minerals. Based on these characteristics, when we do the wetting installation, it is easy to chemically react with the metal minerals in the stone, and result in water crystals. Under normal conditions, it is difficult to evaporate and dry, as a result the stone has a long-term appearance of flooding.Secondary, the use of protective agents or varieties is not properly selected. There are many varieties of protective agents in the market, and different protective agents should be used for different stone materials, different parts of use, and different paving methods. This is often overlooked. More important is the fair choice of construction methods and usage. It is often found that even we used the same stone, same cement and sand, but the wall cladding and flooring still  appear water spots (stains). This situation is basically the result of using a stone protective agents without actually operating requirements. Thirdly, the choice of cement, sand and water consumption during stone paving also have a great influence on water spots and yellowing of stone. In the construction, the alkali content, manganese content, iron content, sand soil content (including impurities) and water should be strictly controlled. Otherwise, the stone will be contaminated by different procedures.

Loading Details Of Stone ProductThe stone product are extremely fragile during the handling and unloading process. If it is accidentally damaged, the loss will be serious. So let us share something during the stone handling process and how to avoid unnecessary dangers.Precautionary and prepared.In order to be safe and free from loss, it can be prepared according to different conditions, product size, quality, distance, and different modes of transportation.▶ If the large-size big slab, we suggest to use the hard wood for firmness.▶ If the small slab, can be bundled with wooden slats and shovel.▶ Specialty  products and handicrafts should be packed in cartons and wooden boxes to protect sharp corners.▶ It is strictly forbidden to pack the white and easily contaminated products with colored plastic and straw rope.▶ The package should be secure and easy to load and unload.▶ You need to write the box number and attached the packing list on the package.▶ Pack with plastic film to prevent rain.▶ The surface of the working piece should be foamed, and the bottom of the package should be filled with two crossbars for loading and unloading. 

Difference Of Marble Crystal Treatment and Mirror Treatment When we talking about MARBLE stone care with people, We always pay particular attention to two key words, “crystal treatment” and “mirror treatment”. Some people usually confuse with them, but for a professional marble stone supplier, these words need to be distinguished.Let see the differences between the marble crystal face and mirror face.First of all, , we can understand the difference in literally.Crystal: The crystal is grown from the liquid or gas phase.Mirror: It is an instrument which used for reflection.From the professional perspective, there are substantial differences between crystal treatment and mirror treatment.Crystal Treatment: It is a chemical reaction. Because of the chemical and physical reaction, the stone surface is formed a hard and dense crystal layer. So that the stone is not easily damaged. It can also be understood as crystallization. After the hot saturated solution cooling, the solution will be crystallized. For example, the marble calcification, the granite silicification and etc. Mirror Treatment: It is a general term for all stone effects. Generally, the mirror surface is just by waxing.

Key Points Of marble Crystal finish Treatment 1. Light-colored marble (Ariston White, Volakas, Calacatta, Arabescato, Sivec White, etc.) can not use the acidity chemical potions for the surface treatment. Light-colored stone has the high iron content, which is likely to cause yellowish surface after reaction with acidity potion.2. The crumbly stone can not use the crystalline material which contains the resin material, otherwise, the resin wax will block the surface pores, It is not conducive to stone ventilation, and easily result the stone re-alkali, yellowing and other diseases.3 The Tropical Brown marble, Dreamy Hainan, French Portoro and other materials which are unevenly and distributed material. These stone must be double crystallized. Otherwise, the stone surface is smooth with touching, but uneven in visual sense after the treatment.4. The soft stone (White Sand Limestone, Moca Cream Limestone, etc.) must be treated with pores shrinking water before treatment, and then double crystallization, otherwise it will show astigmatism.5 Granite and crystallized nano stone can not be polished with steel wool. Otherwise, the powder of steel wool will be sucked into the pores of the stone surface to be yellowing.6 Dark granite must be retouching before crystallization treatment. Otherwise, when the crystal treatment finished, the stone surface will be dull, dry and whitish of the stone surface.

What are the benefits of crystal face treatment for natural stone flooring? As high-grade natural stone flooring decorative materials, its structural components are more complex, it needs to carry out the necessary crystallization maintenance on a regular basis to ensure the decorative effect, to avoid the occurrence of cracks, surface peeling, loss of light, pollution, etc., and to extend the use of stone. Life expectancy, otherwise the decorative effect of the stone will be greatly reduced, and the stone will have a series of symptoms. Stone surface treatment is equivalent to the beauty restoration of stone. After hard treatment of the stone surface, the stone forms a hard crystal layer on the surface. The crystal layer not only improves the brightness of the stone, but also effectively protects the stone from abrasion and pollution. A.National quality standard of floor crystal treatment 1. The stone surface is clean and tidy, the protection is intact and there is no damage.2. The overall stone surface are delicate, oily, bright, Crystal clear.3. The overall stone surface meter test average brightness of marble above 80 degrees, granite, quartz  and nano stone more than 75 degrees.4. The overall stone surface shows the sucker slip effect.5. The overall stone surface exhibits a lotus effect and waterproof. B.What is the general maintenance period of crystal treatment? 1. Because of the small flow of people, generally once a quarter is appropriate for the villa.2. The entrances and exits of hotels and commercial buildings are twice a week.3. The hotel, commercial building, elevator hall and other public areas are once a week.

Ground unevenness is a common problem in paving marble, so it is generally necessary to have mirror polishing treatment after paving.

About the Staircase Design 1.Straight stairs2.Arched/Curved stairs3.Circular stairs4.Spiral stairs5.Quarter turn stairs6.Half turn stairs7.Winder stairs 1.Straight stairs These are the stairs along which there is no change in direction on any flight between two successive floors.According to general rules the amount of treads in one straight flight shall not exceed 16. Despite their simple forms pertinent components may communicate a unique style to the stair case.The most simple in terms of design, manufacture and installation is the staircase with straight flight. 2.Arched/Curved stairs Curved stairs, like spiral stairs are helical how ever, they tend to be on a much larger radius and typically do not make a full circle. The treads in such stairs are wedge-shaped as well, but tapering at one side is not very vital as that at Winder Stairs.They are elegant and graceful in appearance, and with pertinent components the staircase looks very effective. For this reason they are almost always located at the entry where it makes the best first impression.They are very difficult-to-make because all basic details, closed strings and (or)open strings.as well as handrails are curved. 3.Circular stairs These stairs, when viewed from above, appear to follow circle with a single center of curvature and large radius. Circular staircases have a gap down the middle: these typically have two handrails.These stairs are generally provided at the rear of a building to give access for servicing at various floors.All the steps radiate from a newel post in the form of winders. These stairs can be constructed in stone, cast iron or R.C.C. 4.Spiral stairs These stairs are similar to circular stairs except that the radius of curvature is small and the stairs may be supported by a center post constituting the backup abutment for all treads in the flight. Overall diameter of such stairs may range from 1 to 2.5m.Here just like in winder stairs and arched stairs the treads are wedge-shaped, but all of them(except for the last one)are uniform-sized. 5.Quarter turn stairs Quarter Landing Stairs represent a variety of straight stairs, which also include a landing. But here the landing is needed to change a direction of the flight by 90 degrees and at the same time it serves as a place for rest when moving. The landing may change its position in the flight from its beginning and up to its end.Staircases of this type are more convenient and safe than straight staircases. Due to the presence of the landing the flight is divided into two. thereby reducing quantity of treads in one flight, and makes walking more comfortable. 6.Half turn stairs Quarter Landing Stairs represent a variety of straight stairs, which also include a landing. But here the landing is needed to change a direction of the flight by 90 degrees and at the same time it serves as a place for rest when moving. The landing may change its position in the flight from its beginning and up to its end.Staircases of this type are more convenient and safe than straight staircases. Due to the presence of the landing the flight is divided into two. thereby reducing quantity of treads in one flight, and makes walking more comfortable. 7.Winder stairs Winder Stairs are the stairs with a turn by 90 and 180 degrees, but in contradistinction to Quarter Landing Stairs and Half Landing Stairs on turn the wedge-shaped treads are used for their construction.It is no need to construct an intermediate landing, and also to reduce the space occupied by  the staircase.In terms of design, staircases of this type possess soft and flowing lines, which under-line their beauty, of course. And such staircase looks evidently intriguing, as if inviting to go up the radial stairs.
