GRP profiles fiber glass reinforced plastic H beam

JHR mainly focus on FRP products and FRP related machine manufacture and export, we have FRP pipe production line, FRP tank production line, FRP pultrusion machines, FRP grating machines, FRP rebar machine, FRP rock bolt machines and so on.

FRP pultrusion profiles have all kinds of FRP pipe: FRP rectangular pipe, FRP rods, and glass steel beams. The elementary element of the FRP pultrusion profiles for resin and glass fiber(including cloth, carpets, etc) It has good dimensional stability, excellent, corrosion resistance, good surface properties.

Technical support is the most importance in production. As long as FRP developing, new and advanced process, material, equipments appeared. We are giving the eyes on the world FRP relative news and supply customer advanced service.

Features:

1. Good dimensional stability: Heat effect in the processing process of thermosetting resin matrix cross linking form shape mesh structure, its products under the normal size stability is good, after molding shrinkage is small. Products in the long time continuous load under the action of its shape and size change is very small, the creep is small. The creep performance depends on the size of the load, the duration of temperature and load factors. Under the condition of fixed load and temperature, for a long time after loading the slow variables of thermosetting plastics are much smaller than thermoplastics.


2. Excellent heat resistance, high temperature resistant characteristics:After the curing reaction of thermosetting resin matrix composite materials can no longer afford to soften, its products are quite stable, heat resistance with 1.86 MPa load determination, generally the thermal deformation temperature at 150 ~ 150 degree centigrade, the fiber reinforced thermosetting plastics belongs to the excellent thermal insulation material, its thermal conductivity is generally 0.35 ~ 0.47 W/(m.K), only the metal from 1/100 to 1/1000, can be used as a good insulating material and the instant high temperature resistant material, thermal deformation temperature of the material can reach 350 degree centigrade, can be used as a normal temperature and high temperature structural materials. Glass fiber/phenol rocket, missile engine excellent thermal insulation material.


3. Excellent:Composite material is a good electrical insulating materials, if the mica as its electric performance, more excellent packing of products can be used to manufacture electric arc resistance, resistance to voltage, induction electrical superior special parts. Due to the composite material has excellent electric properties, its products there is no stray current corrosion and electrochemical corrosion, which can be widely used in the manufacture of instruments, motor and electrical insulation parts, in order to improve the reliability of electrical equipment and prolong its service life. In addition, the products under the effect of high-frequency permeability, good dielectric properties and microwave have been used in the manufacture of many kinds of radar cover and other high frequency insulation products.


4. Corrosion resistance: Resin matrix composites with ordinary steel electrochemical corrosion mechanism is different, it does not conduct electricity, not have dissolved ions in electrolyte solution, in the atmosphere, water, and thus general concentration of acid, alkali, salt and other medium has good chemical stability, especially in the oxidizing acid and quite a wide ph range medium has good stability. Therefore, has been widely used in the manufacture of corrosion products, to be used for stainless steel can't cope with some of the medium (such as hydrochloric acid, sulfur dioxide and carbon dioxide, dilute sulphuric acid, sodium hypochlorite) corrosion, played a good role.


5. An FRP pultrusion profile has good surface properties:Composite materials with chemical medium contact surface generally have little corrosion, produce, and rarely fouling, so commonly used its manufacturing fluid pipe, the pipe resistance is small, low friction coefficient, save a lot of power. Due to the composite material does not generally easy to generate metal ions pollution medium like metal, so it is also a food and medicine industry widely used composite materials products.In addition, the composite material has the very high friction limit value (pv), under the condition of the water lubrication, the friction coefficient is very small, about 0.01 ~ 0.03, and are thus optimizing material wear-resisting products.

Introduction

Hydraulic type pultrusion machine is controlled by PLC, which adopts hydraulic pressure type to-and-fro as traction force with pneumatic length-fixing cutting. The line consists of roving racks, resin bath, mould calibrating table, to-and-fro traction machine, cutting saw, racks for finished products and control system

 Researches and development team by knowing the importance of the FRP usage in industry and construction , have successfully conducting different researches and studies projects. At the present , it has several government- supported projects available . 

Design and engineering services has been given idea from customers, and make out the thinsg you imaged. Specially developing on new machinary. 

Istallation and construction team is experienced with installation, commissioning and training service at cutomer’s factory. In this way, the customer is able to handle management of equipment themsleves soon. 

Mantiance service is applied when customer cann’t solve problem themselves. Mainly at equipment, software, tools…etc.
