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: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
Q:Plastic doors and windows profiles
The overall quality of plastic doors and windows by the quality of hardware accessories and installation of a great impact, because the domestic enterprises PVC plastic doors and windows profile profile shape and size are not the same, hardware accessories can not be unified, so the production of each variety of parts Can not be large, it is difficult to form a scale effect, in addition, due to the overall level of consumption of domestic doors and windows is still very low, limiting the price of PVC plastic doors and windows, PVC plastic doors and windows hardware accessories prices are too low, causing manufacturers to meet the market had to reduce Cost and make cheaper cheap hardware accessories. Fortunately, the new standards for plastic window hardware is being developed, hoping to standardize the hardware market. Excellent hardware accessories, can improve the overall performance of the window, such as flat window using multi-point locking than a single point of locking the sealing and wind pressure performance is much higher, the use of corner hinge or adjustable hinge its performance It is much stronger than ordinary type or saddle type hinge, it can effectively prevent fan sagging phenomenon. In addition, the use of silicified and the middle of the taps with the top of the top coat is much higher than the ordinary.
Q:What is the quality of plastic steel profiles in the end?
Quality in general, market acceptance can be, but the price is relatively high.
Q:What is the amount of plastic profiles
The size of the sliding window lap affects the sealing of the window, safety, installation, daily use and so on. (12mm-8mm = 12mm), the gap between the fan and the ribs of the box (ie, the slide) is 12mm (20mm-8mm = 12mm). ), This gap for windows to install and pick up. When installing the window, the sash and bottom frame are only 4mm at the top of the ribs. Due to the size deviation of the window frame and sash, the straightness deviation of the window frame installation and the height change of the pulley used will change the actual overlap and installation gap of the frame fan. When the amount of overlap between the fan and the upper frame increases, the installation gap decreases, and the window fan is hard to be installed, and the frictional force of the window and the upper seal block increases, resulting in the opening of the sash; Sealing performance decreased, lap volume is too small, but also increase the risk of sliding window off.
Q:Specification for steel profiles
Before 50, did not use 40 or 38, 10 years ago I have done spliced steel, and now who is willing to splicing ah. But really want to splice, and now have steel can also be spliced.
Q:Plastic steel window profile specifications models which
Plastic window is a form of window that is actively promoted by the state in the mid-1990s after the wood, iron and aluminum windows. Because of its low price, performance and price is better, is still widely used.
Q:Is not aluminum alloy better than steel?
Aluminum alloy usually use copper, zinc, manganese, silicon, magnesium and other alloy elements, the early 20th century by the German Alfred Wilm invention, the development of the aircraft to help greatly, after a World War II German aluminum alloy composition is classified as state secrets. Compared with ordinary carbon steel has a lighter and corrosion-resistant performance, but the corrosion resistance is not as pure aluminum. In the clean, dry environment, the surface of aluminum alloy will form a protective oxide layer.
Q:Plastic profile brittle extrusion process unreasonable reasons
The low molecular weight of the product is not discharged There are two general approaches to the production of low molecular weight components in the product, one at the time of hot blending, which can be vented through the dehumidification and exhaust system during hot blending, partly by partial residual and extruded heat Water and hydrogen chloride gas. This is usually through the host exhaust section of the forced exhaust system to force the discharge, the vacuum is generally between -0.05Mpa-0.08Mpa, not open or too low, will remain in the product of low molecular weight, Resulting in mechanical properties of plastic profiles decreased, resulting in plastic profiles crisp.
Q:Is the powder produced when the crushed plastic is crushed?
Plastic crusher Plastic crusher refers to the crushing of various plastic and rubber such as plastic profiles, pipes, rods, silk, film, scrap rubber products. Granules can be directly for extrusion, as the production of raw materials.
Q:Plastic steel window profile material
The layman is so to say that there is no grade steel, on a model, the standard requirement is to look at the three sex. ABC blind Mongolia Yeah, you will be the best, the price is not expensive 280 steel is a foreign brand? The highest price in the country, but 170-280. Who's how good you are. Are generally about 170 on the OK.
