FRP Bolt: GFRP Bars

Product Description:

Bolt support in coal mines in recent years, railway, highway, water conservancy and urban construction engineering project, at the same time, the rapid development in the glass fiber reinforced plastic (GRP) anchor applied correspondingly, GRP anchor of safety and operability are far more than the metal bolt now used by coal mining, and is gradually replacing the traditional metal bolt, is the new alternative metal bolt supporting materials. Its advantages:

FRP Bolt Glass  reinforced  plastic  anchor  rod

1, high strength, easy cutting rod body: the tensile strength of glass fiber reinforced plastic anchor rod is better than that of ordinary steel, higher than 20% of the steel bar, the same specification and good fatigue resistance performance, light weight, only for the same volume of steel 1/4. Its material is a composite material, easy cutting, can protect the coal winning machine cutting head;

2, safety performance is good, explosion-proof anti-static: thermal conductivity, conductive, flame retardant, antistatic, collision won't produce sparks, through the formula change and metal for tunnel safety construction is very good, especially suitable for gas concentration area;

3, Gao Jiangnai corrosion, high bearing capacity, tensile resistance is strong, the diameter of the rod body strength is better than that of rebar bolts, as a support for a long time, can resist erosion of chloride ions and low PH solution, especially the resistance to corrosion of carbon compounds and chlorine compounds is better.

4, material binding force strong: closer to the cement thermal expansion coefficient compared with steel, so the rod body with concrete grip of stronger;

Light 5, can design sex is strong, easy to operate, stable modulus of elasticity, thermal stress under the size stability, heat bending shape can be arbitrary shape, and weight is only 1/4 of coequal norms metal bolt, can be used in tight Spaces such as tunnels and mines is convenient, make it easier for the construction, reduce labor intensity;

6, construction is convenient, can produce all kinds of different cross section according to the requirement of the user and the length of the standard and non-standard, non-metallic drawstring tie available at the scene, the operation is simple.

Glass reinforced plastic anchor rod production equipment, our company is using the company independent research and development, after more than 10 years of market recognition, production research and development department improve MYC - 1200 pultrusion equipment, with completely independent intellectual property rights, more than 20 supporting patent technology, is a domestic initiative.

FRP Bolt Glass  reinforced  plastic  anchor  rodFRP Bolt Glass  reinforced  plastic  anchor  rod

So far, our company has formed glass reinforced plastic anchor rod of raw materials, production equipment, glass fiber reinforced plastic anchor rod products production and sales of the whole industry chain, pultrusion technology, production, processing and application of full thread glass reinforced plastic anchor rod, the glass fiber content as high as 80%, at the same time because of pultrusion technology of prestressed effect, can greatly improve the strength of glass fiber reinforced plastic anchor rod body, tensile strength can be big, to ultra high strength bolt corresponding technical indicators. And can be installed directly nut, because the rod surface area significantly increase can significantly increase the anchorage rod body strength and tensile strength; Tray, nut supporting with tray, nut of invention patent.

Q:Will the FRP section crack for a long time?
Under normal circumstances, glass fiber reinforced plastic profiles will not appear cracking phenomenon, if there is cracking phenomenon, may be the following reasons:1, the placement method is incorrect, such as irregular, non closed section of a large number of stacked2 、 the resin content in the profile is low, filling is more (see if the section color is whiter, and more powder fall off at the same time)
Q:Are pultruded FRP sections strong? What are its main areas of application?
The tensile strength of products produced by pultrusion process is higher than that of ordinary steel.Widely used in transportation, electrical, electrical, electrical insulation, chemical, mining, marine, watercraft, corrosive environment and life, civil areas.
Q:How to install GRP mark pile
The life of the font (because the FRP material should be polished and polished before printing, so that the printed fonts can be longer and a little bit less concrete)
Q:What are the best manufacturers of glass fiber reinforced plastic pultruded profiles in China?
In addition to the thickness of radome products, there should be other requirements.
Q:What are the circumstances in which the pultrusion should be performed?
(3) the heat deformation temperature of hot deformation temperature high extrusion is 186 DEG C, do not soften at high temperatures, -60 C constant crisp, to ensure the normal use of various environmental temperatures.(4) the water absorption is low, the water absorption of ordinary FRP products is less than 0.5%, while the water absorption rate of pultrusion section is only 0.257%, which is suitable for use in humid environment(5) heat transfer coefficient and low coefficient of thermal insulation rigid PVC pultruded profile approach, made with the single frame double glass insulating window insulation coefficient is only 2.69W/ (M2? K), while the thermal insulation coefficient of the same type of steel, aluminum window made up of 4.0W/ (M2? K). Show that the energy saving glass steel doors and windows is obvious.(6) strong corrosion resistance pultruded profile by 3%HCI solution for 24h, its hardness retention rate was 95%; the 3%NaCl solution for 24h, its hardness retention rate of 89%. so the FRP pultruded profiles for making doors and windows is not only suitable for general residential houses, hotels, restaurants, and more suitable for coastal areas and the corrosive working environment of industrial plant use.(7) to meet the requirements of the environment, the production process of the extruded section has the characteristics of low noise, high efficiency, low power consumption, low pollution, etc., and it conforms to the relevant environmental requirements of the state
Q:What are the characteristics of FRP products?
Corrosion resistanceFRP is a good corrosion resistant material. It has good resistance to atmosphere, water and acid, alkali, salt, various kinds of oils and solvents. Has been applied to all aspects of chemical corrosion, is replacing carbon steel, stainless steel, wood, nonferrous metals and so on.
Q:The difference between polyurethane pultruded profiles and glass reinforced plastic profiles
Compared with other materials, pultrusion with polyurethane can produce a variety of benefits. The utility model can improve the content of the glass fiber in the product and greatly improve the strength of the product. For example, pultruded window frames made of glass fiber and polyurethane resin, the strength of the resulting window frames is 8 times higher than that of the PVC window frames, and the conductivity is 40 times lower than that of aluminum. Therefore, the insulation performance is much better.
Q:What are pultrusion materials used for?
Various sections of Glass Fiber Reinforced Plastic Pultruded sections can be produced with different sections of the die. The profile has the characteristics of high strength, corrosion resistance and light weight
Q:What are the main uses of pultruded glass fiber reinforced plastic extrusions?
Road transportation shopping malls, the successful use of: highway barrier fence on both sides, road signs, pedestrian overpass, noise barrier, refrigerated vehicle components.
Q:What does M23 grade of glass fiber reinforced plastic section mean?
There are many kinds of FRP Pultruded Shapes, such as glass fiber reinforced plastic round tube, glass fiber reinforced plastic square tube, glass fiber reinforced plastic rectangular tube, glass fiber reinforced plastic round bar, glass fiber reinforced plastic i-beam.
