1) stainless steel
Steel resistant to corrosion by weak corrosive medium such as air, steam, water and chemical corrosive medium such as acid, alkali and salt. Also known as stainless acid - resistant steel. In practical application, the steel that is resistant to weak corrosive medium is often called stainless steel, and the steel that is resistant to chemical medium corrosion is called acid-resistant steel. Due to the difference in chemical composition, the former is not necessarily resistant to chemical medium corrosion, while the latter is generally rust free. The corrosion resistance of stainless steel depends on the alloying elements contained in the steel. Chromium is the basic element to make stainless steel corrosion resistance, when the content of chromium in steel reaches about 12%, chromium and the oxygen in the corrosion medium, the formation of a very thin oxide film on the surface of steel (self-passivation film), can prevent the steel matrix further corrosion. In addition to chromium, common alloy elements include nickel, molybdenum, titanium, niobium, copper, nitrogen, etc. Stainless steel is usually divided into: (1) ferritic stainless steel. Contains 12% ~ 30% chromium. Its corrosion resistance, toughness and weldability increase with the increase of chromium content. (2) austenitic stainless steel. Chromium content is more than 18%, but also contains about 8% nickel and a small amount of molybdenum, titanium, nitrogen and other elements. Good comprehensive performance, can withstand many kinds of medium corrosion. (3) austenitic - ferrite duplex stainless steel. Both austenitic and ferritic stainless steels have the advantages of superplasticity. Martensitic stainless steel. High strength, but poor plasticity and weldability. Stainless steel for civil use usually has the following Numbers: 304, 303, 302
, 202, 203, 201 in outdoor furniture, 304 type use more, so the model of stainless steel hardness, corrosion resistance is strong, so the exposed stainless steel products are often used this model. And the anti-corrosion requirements are not high, or on the surface of stainless steel spray treatment of products, mostly use 201 or 202 stainless steel, this model of stainless steel compared to 304, the anti-corrosion performance is not as strong as it. Usually these different types of stainless steel in the appearance is difficult to distinguish, in general, we will use stainless steel detection liquid to distinguish. Due to the anticorrosive properties of stainless steel, it is widely used in furniture materials with high cost performance. Stainless steel in the process of polishing and drawing points. Polished stainless steel has very good reflective, but it is easy to mix with ferroelectric degree, so outdoor furniture is not used much, more for tableware; Brushed stainless
Steel treatment with flexible metal color, and the appearance gives a person a sense of a lot of high-grade, is the common way of outdoor furniture at present.
Due to its excellent corrosion resistance, light quality, high ductility and moderate strength, aluminum is widely used in outdoor furniture production. Usually, the material will be sprayed on the surface in production to match colors. Or electrochemical treatment of the surface.
Iron material has the advantage of high strength and good support for products, but the disadvantage is heavy quality, not easy to handle, easy to corrosion, easy to rust. Reason is used at low-end cast iron product more on furniture production, want to do antirust processing in normal use. Such as the common park chair. www.sz-fengyuan.com
4) stainless iron
The so-called "stainless iron" means that the recovered scrap iron, lead, steel, etc. are processed through the second return furnace and are processed through "magnetic" removal
Cr stainless steel, there is a certain anti-corrosion capacity! Stainless iron is not a common saying, commonly considered to have ferromagnetic stainless steel.
Second, the wood
Teak origin is usually in Thailand, myanmar, Indonesia and so on, in China's yunnan also has a small number of existence. Because teak contains rich oily, reason its stability is better than other lumber, use teak in furniture so, can reduce the craze of woodwork, be out of shape, become angry, moth-eaten wait for worry. The teak of different producing area, as a result of climate, soil wait for the different growth environment, quality is not identical also. With Thailand, myanmar teak for the best, wood more aromatic, more not easy to be moth-eaten, texture clear, beautiful, elegant colors, products not only have good use value, more high collection value, so is called wood gold.
Northeast China ash
Manchuria produced in northeast China, because of tough material, beautiful texture, rough structure, easy processing, toughness and other characteristics, is a good material for furniture. Reason is used extensively on outdoor furniture, wait like commonly used park chair.
First of all, we must make it clear that FSC is not a name for wood, it is a general term for certified wood. FSC is a mature and perfect FOREST certification system at present, which comes from the first letter of the English word FOREST STANDARS CONTACT. It is also the abbreviation of FOREST Stewardship Council, so FSC is a symbol of FOREST management certification. For consumers, the natural disasters caused by forest loss are directly related to people's consumption behaviors. Even if you don't cut trees, you may be part of the destruction. No trees are planted, but a forest can be protected. It all depends on consumer behaviour. To buy green wood products is to protect the forest, the forest ecosystem, soil and water conservation and wildlife habitat. FSC certified wood is recognized by the world environmental protection organization, and the use of FSC certified wood also makes a contribution to environmental protection. And usually products made from FSC wood carry an FSC certificate. Therefore, FSC is not a kind of wood, but a general term for wood that can be used and is certified by FSC.

Other hard woods such as Indonesian red cherry wood
There is no need to introduce plastic, which is a well-known material. This article mainly introduces the related materials of plastic used in outdoor products.
Imitate cane is to point to outdoor furniture USES cane is to be made with plastic raw material, use PE or PVC to be main material to produce normally, in order to increase the anti-ageing degree of plastic, increase proper anti-ageing raw material through recipe normally. Therefore, imitation rattan is also called PE rattan. PE material belongs to polyethylene, which is a kind of environmentally friendly plastic at present. Therefore, it is widely used in the civil market. According to the color requirements, add some pigment, can produce a variety of color cane. And according to the shape requirements; Canes of different shapes can be produced. Compared with the real rattan in nature, the imitation rattan has the characteristics of beautiful appearance, bright color, long service life and comfortable feel.
Some of the awning cloth in outdoor furniture and the top cloth of sunshade products are made of PVC material, which is consistent with the rattan imitation material, but the manufacturing process is different.
Granite: natural formation, hard texture, beautiful natural texture. If the usual use of jinsha black, black Mongolia and other stones. Most of the countertops in outdoor products are made of granite, which is used for countertops. There is no need to add appendages such as backboards at the bottom. Marble: is also naturally formed, texture than granite to soft, density is not as big as granite, easy to crack in use, so often used for small area mesa, or add back plate protection at the bottom of the mesa.
Resin: synthetic resin with chemical composition, similar to natural stone material, with complex production process requirements and high technology content. It is still in the trial stage in the use of outdoor products and is not mature yet. Mainly used for interior decoration. Honeycomb aluminum synthesis: the surface paste 5mm thick natural stone, at the bottom of the stone with honeycomb aluminum plate as the bottom support, between the two sides with special glue bonding, high pressure finalized. This stone is mainly used for the table, the advantage is that the table weight is light, easy to carry. The disadvantage is that the production process requirements are higher.
Five, the glass
Tempered glass: after high temperature quenching glass, the impact strength increased, bending strength increased, thermal stability, resistance to large temperature difference changes. After crushing, uniform particles are formed.
Reference document "what is tempered glass" www.fengyunhuwai.com
At the bottom of ordinary glass through a special process of high temperature ink, and then high temperature curing molding. The glass made in this way with different colors is called silk-screen glass.
Textile and other
Chemical fiber cloth is usually used for cushion, umbrella cloth, tarpaulin, etc. This kind of fabric usually has to be treated with three defenses before it can be used outdoors. Three prevention means preventing water from splashing, preventing ultraviolet rays,
Anti-mildew and oil pollution; Three principles is through a special process, form a layer of rubber film on the surface of fabric, naturally formed in the process of rain water outflow, so have waterproof effect, due to the fabric surface covered with colloid, hard water molecules into the fibers, then prevent mildew and oil seepage problem, fabric through special processing, increase resistance to UV components, so it can prevent ultraviolet ray, after the sun does not fade and aging problems;
Rafa Lin cloth
Tesling cloth is a special material introduced in recent years, which has the characteristics of high temperature resistance, ultraviolet resistance, rain resistance and aging resistance. In recent years, it has been widely used in outdoor products with very good performance. Waterproof anti - ultraviolet function can make table mat, carpet, curtain, outdoor beach chair fabric, more widely used. Colourful, wear resistance, water resistance, oil resistance, resistance to purple line, nontoxic, etc. The geographic rafa Lin cloth is covered with a layer of glue, there is tensile resistance of fiber line, woven by the special process, because of the characteristics of PVC net cloth, so most of the products are used in outdoor leisure products, beach chair, beach bed, for example, outdoor chair
