High strength frp square tube/Square Hollow Steel Tube/Square Pipe

                                High strength frp square tube/Square Hollow

                                          Steel Tube/Square Pipe          

  Frp square tube 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

Company can also customize product according to customer requirements, such as perforation sizes, different shapes, different sizes, different load requirements, maximize meet customer demand, and reduce losses to a minimum, cost savings for customers. 

                                                                              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 the stairs and railings, operating platform, corridor, bracket, etc.

   company was founded in 1993, we introduced the most advanced fully automatic pultrusion production equipment, products and materials including instruments imported from the United States.In addition, the company all staff by the specialist training in the United States.For more than 20 years, through the efforts, we constantly innovation, enlarge the range of products.Our company has become one of the best production of FRP pultrusion products manufacturers.
