Pultrusion solid high strength FRP Round Bar

FRP Round Bar/steel solid round bar/Round Steel Bars  

Glass fiber reinforced plastic round rod is composed of unsaturated polyester resin, continuous glass fiber yarn,

glass fiber mat, pultrusion process control, process is irreversible, it can't melt or form again, again has high

strength, light weight, antiseptic, beautiful, impact resistance and other characteristics.

Molding process

During the pultrusion process, the raw material are pulled through a heated steel forming die using a

 continuous pulling device when the reinforcements are saturated with the resin mixture in the resin

 bath and the wetted reinforcement package is wrapped in a surfacing veil. the completed package

 then goes into premolding stage that roughly forms the package into the appropriate shape to enter

 the heated trimming die for curing. the trimming die is the exact shape of the final part desired. upon

 exiting the trimming die, the part is over 90% processing and solid. Cutting in accordance with 

requirements of the length, the entire process is completed.

 Product specification

 Product advantage

(1) high strength Pultrusion profiles is 150-300 mpa tensile strength, bending strength of 200-300 mpa,

the 1000 h after artificial accelerated aging of bending strength retention rate can reach 78%. 
(2) low deformation rate Glass fiber reinforced plastic pipe by 1000 h after artificial accelerated aging change

in length is + 0.03%, the width of the rate of 0.07%.Therefore making products with the pultrusion

profiles geometric shapes and sizes can keep the long-term stability. 
(3) high thermal deformation temperature Pultrusion profiles of the thermal deformation temperature of

186 ℃, high temperature softening, 60 ℃ the same crisp, to ensure the normal use of various kinds of

ambient temperature. 
(4) the bibulous rate is low General purpose bibulous rate is less than 0.5%, and the bibulous rate of

pultrusion profiles is only 0.257%, suitable for use in damp environment. 
(5) low coefficient of heat preservation and heat insulation heat transfer coefficient of pultrusion profiles

with hard PVC close, made of the single frame of the double glass window insulation thermal insulation

coefficient of only 2.69 W/(m2K), and with the same type of steel, aluminum ingot the coefficient of

heat preservation and heat insulation of the window is as high as 4.0 W/(m2K), shows that FRP doors

and Windows of energy saving is obvious.

  widely used in petroleum, chemical industry and other corrosion environment of stairs and railings, operating

platform, corridor, bracket, etc.
    

 company was founded in 1993, we introduced the most advanced fully automatic pultrusion production
