Pultruded Profiles
The fiberglass roving, continuous fiberglass blanket and surface felts are fully infiltrated with unsaturated polyester resin, then passed through a certain cross-sectional shape of the mold, under the traction of the pultrusion machine, through heating continuous curing molding, to produce FRP pultruded profiles. The weight ratio of the profile is 35% resin mixture and 65% glass fiber (according to the mechanical requirements, the lay-up design and yarn content can be adjusted), and the pultruded profile of Shirui meets and exceeds the relevant standards of EN13706 E23 or GB/T31539-2015 M23.
We can improve the performance not only by material selection and process design such as lay-up, but also by optimizing the cross-section and structure to meet specific requirements.

Pultruded profiles technical performance
The dense fiber core layer makes the profile tough and firm, and its absolute values of longitudinal bending strength and impact strength have exceeded those of ordinary steel. The use of glass fiber mat increases the transverse strength of the profile and forms a rich resin layer on the surface, which makes it have good anti-corrosion and anti-rupture characteristics.

FRP pultruded profile is a structural member with the advantages of light weight and high strength, corrosion resistance, insulation and non-magnetic.
FRP pultruded profiles also have good designability. Various profiles can be made into various products through proper connection and combination, such as: structural platform, frame beam, bracket, fence, inclined ladder, straight ladder, guardrail, etc., which are widely used in different fields.
