Product Description:

FRP grating:

FRP grating is made of a glass fiber reinforced materials, unsaturated polyester resin as the matrix, through special processing composite made of a plate-like material with a lot of space, it can be used as a structural material, used as a corrosion environment floor, trench cover, platform, ship decks, stairs, plank and so on.

Grille through a glass fiber braided, resin cast integrally molded together, making the distribution of many of the rules with a rectangular, square spaces FRP grid plate, with two-way mechanical characteristics of the same sex. It can be widely used in petroleum, chemical electronics, electricity, paper, printing and dyeing, electroplating, marine exploration, sewage treatment and other industries working platforms, equipment platforms, drilling platforms, walkways, etc., are ideal for corrosive environments, but also applies to civil construction on facilities.

FRP grating has a long life, low cost, safe, reliable, maintenance-free, as well as beautiful series of advantages. Has been promoting the use of such products in the United States thirty years, FRP grating production and use of sales have been standardized, serialized, the commercialization, the amount is quite large. In the Gulf region, the reconstruction of the Middle East oil fields, the experts, that the use of FRP grating is the most economical and reasonable material, which is being heavily used. FRP grating is also being used in Asia, Singapore, Taiwan and other regions.

Actual size according to customer needs, can be cut stitching. Use stainless steel grille snaps between the glass plates require stitching connection.

FRP grating characteristics:

1 anti-corrosion: a very superior acid and alkali resistance, and many other organic solvents and salts gas, corrosive liquid medium can, in the field of preservation has incomparable superiority. According to the actual requirements of the case, can be selected and used phthalic economic type, isophthalic, vinyl type resin as the matrix material.

2 light weight, high strength, and easy to cut, the installation: the resin and because it is made of glass fiber composite with a density of not less than 2 kg per cubic centimeters, only a quarter of steel, aluminum 2 / 3. Its strength is 10 times of rigid PVC, aluminum and absolute intensity level than ordinary steel. Its light weight, can greatly reduce the base support, thereby reducing the material cost of the project. Its cut is easy to install, no flare and large lifting equipment, only a small amount of manual and electric tools, making the installation costs are greatly reduced.

3 anti-aging: life in more than 30 years.

4 flame: Common flame retardant grill flame propagation rate (ASTM E-84) does not exceed 25; flame retardant vinyl grill senior propagation rate does not exceed 10. Oxygen index of not less than 28 (GB 8924).

Q:What is the quality of plastic steel profiles in the end?
08 years to now has been doing the money, it began to have no conch and Shide famous, but it is higher than the other brands, the reason it is a high proportion of plastic, that is less talc powder, the other three sealed pad The bridge is split, so that the fan does not account for the proportion. Speaking of two-color co-extruded, it is the technology is ASA technology is always the most leading, there is no fade, and gorgeous and glossy, which is other profiles can not be compared, I used to vote in the tender angle, , Shide, Zhongda, Huaan, ... .... 10 years did appear broken material situation, has not yet been found.
Q:Plastic profile brittle extrusion process unreasonable reasons
Excessive or insufficient material This is related to the process temperature setting and feeding ratio. The temperature setting is too high to cause the material to be plasticized. Some of the components with low molecular weight in the component will decompose and evaporate. The temperature is too low. Fully welded, the molecular structure is not strong, while the feed ratio is too large cause the material heating area and shear increases, the pressure increases, easily lead to plastic; feeding ratio is too small material heating area and shear reduction, Resulting in less plasticized, whether it is plastic or plastic surgery will cause plastic profiles crisp cutting collapse phenomenon.
Q:The difference between steel and aluminum alloy profiles
Aluminum doors and windows better, but I said that this aluminum alloy is not an ordinary aluminum alloy, its full name is called "heat insulation bridge aluminum" profile. This kind of aluminum alloy doors and windows profiles, it is more complex than ordinary old aluminum alloy structure, thickness and strength and finish much higher than the old aluminum alloy doors and windows profiles, his structural design more scientific and efficient for the family to save energy , With good insulation noise, cold insulation properties, not easy to deformation, discoloration, corrosion resistance and rugged than plastic steel profiles are several times higher. In the decoration of doors and windows, for steel windows and broken bridge aluminum alloy doors and windows of choice, broken bridge aluminum doors and windows of the cost is much higher than the steel doors and windows.
Q:Plastic doors and windows and plastic windows do not like?
According to the material plastic doors and windows can be divided into PVC plastic doors and windows and glass fiber reinforced plastic (FRP) doors and windows. The following are the same as the " 1, PVC plastic doors and windows 1) In all kinds of building windows, PVC plastic windows in saving energy production profiles, recycling of recycled materials and the use of energy consumption has a prominent advantage in the insulation and energy saving has excellent performance and low cost. The following are the same as the " 2) In order to increase the rigidity of the window, in the window frame, sash, the tread profile of the force bar, should be based on the strength of the wind pressure design and other requirements to determine what kind of reinforced steel. The following are the same as the " 3) Coextrusion of UPVC resin with colored polymethyl methacrylate (PMMA) or acrylonitrile-styrene-acrylate copolymer (ASA), as well as coating on white profiles, can be coated with a variety of textures and A variety of surface color decorative effect. In addition, UPVC resin powder is also added to the pigment mixture extrusion of the body dyeing technology. But there are still different views on this technology, it should be particularly careful in the selection, to check the kind of profiles by artificial accelerated aging test after the color changes. It is recommended to coat the color film with the color film to improve its weatherability.
Q:China 's top ten brands of steel profiles in 2014
In the financial financial steel doors and windows is a national key high-tech enterprises, is the industry's well-known brands, the national one of the top ten brands of steel doors and windows, it has Zhejiang Zhongcai profile company production. A large multinational company headquartered in Germany. It is the international profile of the North New North new steel doors and windows is China's largest new building materials group. The company has created more than 30 years of history, it is also well-known trademarks in China. The market occupies a certain proportion.
Q:What is the steel profile?
GB 8814-2004 according to the thickness of the main section of the profile will be divided into three categories of ABC, according to the "visible wall thickness minimum / non-visible wall thickness minimum" said, A type of wall thickness of 2.8 / 2.5mm, B Type of material requirements wall thickness 2.5 / 2.0mm, C type of wall thickness does not specify the requirements. The mainstream of the national standard profiles are Class B.
Q:Is not aluminum alloy better than steel?
Plastic shortcomings: Each product has its shortcomings, with the extensive use of steel profiles, some shortcomings also will be exposed. China's steel profiles most of the poor quality of the use of lead salt stabilizer, finished lead content between 0.6% -1.2%. Lead is a harmful substance to the human body, when the poor quality of aging, will precipitate lead dust, long-term exposure will lead to excessive lead in the blood, and even lead poisoning. The recent introduction of calcium and zinc and organic tin solution to solve the product contains Lead problems, but because of price reasons and technology immature, there is no large-scale application.
Q:What is the material of steel
Plastic steel profile referred to as steel, the main chemical composition is PVC, it is also called PVC profiles. Is widely used as a new type of building materials, because of its physical properties such as rigidity, flexibility, corrosion resistance, excellent anti-aging properties, is usually used as copper, zinc, aluminum and other non-ferrous metals excellent substitutes.
Q:The main features of steel profiles
In the building construction is mainly used for sliding, sliding doors and windows, fence, pipe and ceiling material applications, through the new process is also widely used in automotive engine protection board, not only light weight, and good toughness, with just fine Nature, and sometimes also known as alloy steel.
Q:Will the model of steel profiles (such as 88-type extrusion profiles, 80 extrusion profiles) is based on what to develop ah
Strictly speaking, refers to the width of the bottom of the window frame profile. 88 is that the bottom of the frame width of 88 mm. And some profiles are not absolutely accurate, take the approximate value
