The aluminum alloy plastic steel processing department can set up a cooperative

You can be sure that you can definitely be established. But the magnitude of this effect is worth pondering. It is recommended to do a market research first, such as looking for a new owner** to ask about this problem, and consult more tentatively to see everyone's interest and enthusiasm.

I haven't seen what you said yet, and it's even the first time I've heard of it, first of all, I'm very interested, since it's a new thing, there are no rules to follow, so you need to use more brains and innovate more.

I hope you work hard to succeed. I admire your idea.

The proposal on the second floor is very good, indeed, it is really to serve the common people, then there will be a lot of feasibility.

If you are successful, you can find ** to publicize it, maybe you are the ancestor of this aspect.

It's kind of interesting, it can be **.

It is recommended to set up cooperatives, now the aluminum alloy and plastic steel market is too non-standardized, the ultimate victim is the people, many processors have betrayed their conscience for profit, aluminum alloy with the thinnest, plastic steel with fake materials and the steel lining inside is as thin as paper, some simply do not put the steel lining, the price is still according to the price of the real material, the people do not know what kind of safety hazards they have in their windows, basically repair every year, the processing households can not care about you, each repair also add money. With the supervision of a special agency, and it is easy to do more work, it will not cut corners, and it is the people who will benefit, and in turn the processing households will also benefit.

Grass: Advertise, don't believe it

Plastic steel is cheaper in terms of price, k value (an index to measure the heat transfer coefficient, the smaller the better) is also smaller than aluminum alloy, and the thermal insulation performance is better, which is widely used in colder areas in the north. The disadvantage is that the style is relatively simple, the mold opening fee is expensive, and the surface is easy to age because it is plastic, and the durability is not as good as that of aluminum alloy.

There are many styles of aluminum alloy, which is easy to open the mold, and the K value can also meet the needs of thermal insulation if the thermal insulation profile is used; It can be used as a low-end product or as a high-end product, and it can be made into a high-grade product; It is widely used in southern regions and coastal areas; Since aluminum alloy is relatively soft, it is also easy to machine.

Aluminum alloy and plastic steel have their own advantages and disadvantages, depending on the actual use. If it is a cold area in the north, such as Harbin, it is recommended to use plastic steel, and aluminum alloy is better in the south.

To sum it up:

Plastic steel: good heat insulation, fast aging and discoloration, soft texture. It is well sealed, suitable for windows, not suitable for doors.

Aluminum alloy: slightly poor thermal insulation performance, aging resistance, higher hardness than plastic steel, and strong. The sealing is slightly poor, and the doors and windows can be made and durable.

Broken Bridge Aluminum: It's good, it's expensive.

To add that in the west, southwest, and northwest of our country, ultraviolet rays are relatively strong. The low-end products of aluminum alloy cannot meet the requirements of heat insulation, and the broken bridge aluminum is too expensive. There is a profile called aluminum composite.

Aluminum-plastic composite profile is a composite of aluminum profile and plastic profile, that is, the outer aluminum alloy frame and the inner plastic profile frame. The aluminum-plastic composite profile is specially designed and structured, organically combining the performance advantages of the two materials, which not only meets the requirements for doors and windows in terms of structural strength and aging resistance, but also has excellent thermal insulation, heat preservation, decorative effect, and is simple and convenient to assemble.

Of course, aluminum alloy is good, plastic steel aging is much faster than aluminum alloy, and the strength will decline rapidly after aging.

Aluminum alloy is an alloy with aluminum, the content of which is more than 95%, and zinc, magnesium (containing silicon, copper, iron, titanium, nickel, manganese and other impurities). Strength vs. weight.

The strength of aluminum alloy is 3 times that of plastic, and the wind pressure resistance is two levels higher than that of plastic steel. The cross-sectional area of the aluminum alloy door frame is only 1 3 of plastic steel, and the weight of the window frame is much lighter. Due to the low material strength and rigidity, although the steel lining is added, the wind pressure resistance and watertightness performance of plastic steel doors and windows are two grades lower than that of aluminum alloy windows.

However, because the plastic window steel lining is not connected to a complete frame system in the inner cavity of the profile, the strength of the plastic welding corners of the window frame, the four corners of the fan and the T-shaped node is relatively low, so it should be used cautiously in high-rise buildings.

Gas-tightness. Because the frame and sash structure of the plastic window are welded, its air tightness is slightly better than that of the screwed aluminum alloy window, but the size accuracy of the aluminum alloy window profile is higher, and the frame and fan are more tightly matched, so the two are still at the same level of level.

The coefficient of linear expansion of deformed plastics is 3 times that of aluminum alloys. Plastic windows are deformed by heat, become brittle when cold, and the stability of size and shape, often use the steel of glass to prevent the deformation of the window frame.

Decorative aluminum alloy is rich in color and strong in decoration, and the use of heat-insulated energy-saving windows can achieve indoor and outdoor two-color decorative effects, which can meet the individual requirements of different quality real estate and business buildings.

Safety and environmental protection.

Aluminum alloy is resistant to high temperature and non-flammable; It is a good conductor, which can avoid lightning and anti-static; It can be used and is beneficial to environmental protection. Plastics are not resistant to high temperatures and support combustion; It is an insulator, but it needs to be anti-static; Slow degradation, not usable, slow combustion will release toxic gases, which has an impact on environmental protection.

Weather resistance and corrosion resistance.

Aluminum alloy has better weather resistance than plastic and can remain unchanged for more than 10 years. PVC materials will age. At present, China's plastic doors and windows mainly use the lead salt formula of Germany and Austria, and individual enterprises use the organic tin system formula of the United States.

The domestic artificial accelerated photoaging test shows that the white profile of the sweat lead salt stabilization system is easy to be colored and polluted after photoaging, and the color turns significantly yellow after 1500 hours of light irradiation, and the organic system formula is a little better. In addition, the plastic window shows that it will become rough by weathering, after a few years, the regolith layer has, and there is a layer of poly below Xi Bing will stop decomposing, and the polymer PVC resin will break under the action of ultraviolet rays, and the macromolecular chain will be broken, which is the material showing tarnishing and chalking, so as to see the mechanical properties of the profile decline.

Practical scope and development trends.

Aluminum alloy doors and windows have high strength, good rigidity, light weight, good fire resistance, weather resistance, corrosion resistance, environmental protection, thermal insulation effect has been greatly improved, rich color, mature technology, cost-effective, acid and alkali corrosion environment is suitable for various occasions, especially high-end quality real estate and office buildings.

Coastal and developed cities that have taken the lead in using plastic windows have begun to apply a large number of aluminum alloy doors and windows. At the same time, according to the national environmental protection, energy-saving policy requirements and the development law of the building door and window industry and the current analysis, aluminum alloy doors and windows will be used in large quantities, especially with the central control glass of high-grade aluminum alloy doors and windows.

Everything is relative, depending on your area and the performance to be paid attention to, in the north or recommended plastic steel windows, after all, thermal insulation is the first, domestic plastic steel is not good can use imported Vika, Ruihao, Kemeiling, YKK, LG, etc., the south is recommended to use aluminum alloy windows, after all, to consider the deformation of doors and windows.

Aluminum alloy doors and windows are recommended, and broken bridges can be considered if conditions permit. No matter what kind of aluminum alloy doors and windows, their surface treatment and profile structure are preferred.

I have never seen aluminum alloy rust under normal use, to be able to rust is definitely the kind of product below the 3 lines, this product has no national standard requirements at all, the surface of the profile is rough and other problems.

The durability of aluminum alloy and plastic steel will be deformed in a few years.

When you buy something, pay attention to the cost performance!!

If you don't consider **, it is recommended to use broken bridge aluminum.

Plastic steel is good, aluminum alloy is afraid of rust.

1. The difference between the strength and weight of aluminum alloy and plastic steel.

The strength of aluminum alloy is 3 times that of plastic steel, and the wind pressure resistance is 2 grades higher than that of plastic steel. The cross-sectional area of aluminum alloy window frame is only 1 3 of plastic steel window frame, and the weight of window frame is much lighter. Due to the low strength and rigidity of the material, although the steel lining is added, the wind pressure resistance and watertightness of the plastic steel doors and windows are 2 grades lower than that of aluminum alloy windows.

Second, the difference between aluminum alloy and plastic steel material.

Aluminum alloy is a metal. It is characterized by low density, but relatively high strength, close to or more than high-quality steel, and good plasticity. At the same time, aluminum alloy can be heat treated to obtain good mechanical properties, physical properties and corrosion resistance.

Plastic steel is still plastic in nature, and it is made of polyvinyl chloride (PVC) resin as the main raw material, plus a certain proportion of stabilizers, colorants, fillers, ultraviolet absorbers, etc., and is extruded into the molded material.

3. The difference between the application field of aluminum alloy and plastic steel.

All kinds of aircraft use aluminum alloy as the main structural material; Plastic steel is widely used in building materials.

1. The concept is different.

Aluminum alloy is the most widely used non-ferrous metal structural material in industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industries. With the rapid development of the industrial economy, the demand for aluminum alloy welded structural parts is increasing, which makes the research on the weldability of aluminum alloy also deepen. At present, aluminum alloy is the most widely used alloy.

Plastic steel profile refers to the PVC profile used to make doors and windows, because the strength of the doors and windows processed by PVC profiles is not enough, steel is usually added in the cavity to enhance the firmness of the doors and windows, so the plastic doors and windows made of steel inside the profile are usually called plastic steel doors and windows. With the widespread use of plastic steel doors and windows, the PVC profiles used to make plastic steel doors and windows are commonly called plastic steel profiles. Plastic steel is also a common material for guardrails.

2. The material is different.

Aluminum alloy doors and windows are made of alloy aluminum, the appearance is good-looking, easy to install, high-quality aluminum alloy doors and windows have high strength, but the heat and sound insulation effect is poor, because the aluminum heat conduction is fast, the existing broken bridge aluminum alloy window, the practice is divided into two parts inside and outside, the middle is connected with nylon strips, and the nylon strips play the role of blocking temperature, but the cost is high.

Plastic steel doors and windows are plastic doors and windows at the beginning, that is, the window frame material made of plastic, and then the seams are hot-melt bonded together, the advantage is that the heat and sound insulation effect is good, but due to the poor overall strength, so the steel lining is added in the frame to improve the strength, and the good sound and heat insulation effect is retained, so it is very fashionable, and the performance is basically the same as the process is constantly upgraded, and now it is basically the same, but the doors and windows with the same performance are cheaper than plastic steel.

3. The applicable scenarios are different.

Aluminum alloy for outdoor use, because aluminum alloy has metal characteristics, the service life is longer, plastic steel may crack after exposure to the sun, and plastic steel is cheaper, the reason why there is plastic steel is because it is cheap and suitable for the public.

In fact, each has its own benefits. Aluminum alloy doors and windows, the advantage is that the material is light, the appearance is beautiful, strong, durable, basically do not need how to maintain, Taiyuan market is generally cheap about 180 to 200 (there is a better material price to say), the disadvantage is that the aluminum alloy material heat dissipation is fast, the insulation performance is not good, and the sealing performance is not good. Plastic steel doors and windows, the advantage is that the thermal insulation effect is good, the sound insulation effect number, the installation of double glass, triple glass is easier, generally in 220 to 270 (material quality, glass quality, thickness has an impact on **), the disadvantage is that the life is short, the material is not good for about 8 to 10 years, plastic steel material because of the relationship between the material, the color is single, generally white, after a long time of use some yellow.

I suggest you install aluminum broken bridge doors and windows, broken bridge doors and windows to overcome the shortcomings of aluminum alloy, plastic steel, it is in the aluminum alloy doors and windows to add heat insulation strips, beautiful appearance, a variety of colors, sturdy, durable, thermal insulation, sound insulation than plastic steel, can be installed layer glass, basically no maintenance, long service life, **generally between 480 and 600 (**according to hardware, window type, glass).If you don't consider it, you can also install aluminum-wood doors and windows, which are expensive, probably more than 1200. Personally, I suggest that you install aluminum alloy broken bridges, and now Beijing, Dalian and other large cities are promoting this kind of glass, I believe that Taiyuan will start in about 5 years; Popular, for warmth you can install low-e glass.

1. Compared with plastic steel material, aluminum alloy material is relatively better.

1. Material: plastic steel is plastic (PVC) mixed steel, except for a few big brands that have real steel, the others are almost pure plastic; Aluminum alloy windows are metals, mainly aluminum, and magnesium, manganese, chromium and other metals are added to improve the strength of aluminum alloy.

2. Thermal and sound insulation effect: This is the advantage of plastic steel material, plastic steel material has better sound and heat insulation effect than aluminum alloy material, aluminum alloy is metal, and has the characteristics of fast thermal conduction. The problem is that as a window, the largest area is glass, and 95% of the heat is directed away from the glass surface.

In addition, aluminum alloy is now in addition to a lot of materials that specialize in heat and sound insulation.

3. Color: Since the material itself is plastic, it is mainly white, which is also the best, and other colors are aging very quickly; The surface of the aluminum alloy is baked paint, there are many colors, almost any color can be, and the color is durable, and will not change color and paint off.

4. Fast aging: plastic steel windows (except for a very small number of engineering materials) aging is very fast; The aging rate of aluminum alloy is very slow, so more and more middle and high-end real estate developers choose aluminum alloy.
