Pultrusion Profiles
Pultruded Grating
Pultruded FRP Grating is made of I type or T type pultruded bearing bars and cross members. It has the same chemical properties as Moulded Grating but with higher mechanical properties in the span direction. It is widely used for platforms, especially where large spans are required. It is designed to be long lasting, chemical and corrosion resistant with a high strength to weight ratio and slip resistant. It’s fire resistancy is tested in accordance with ASTM E-84. It is impact resistant, non conductive, easy to cut and install as well as being extremely economical. Pultruded FRP grating is widely used in corrosive environments, such as acid-alkali platforms, acid-alkali depots and water treatment plants, cooling towers etc. Also, the Pultruded FRP grating can be manufactured with cover board and slip resistant surface according to customers’ requirements.

Pultruded FRP Profiles are made of continuous fiberglass roving, resin and surface veil. The raw materials are processed through a pultrusion machine. After the glassfibre is dipped, it is heated into profiles of various shapes and sizes. The tensile strength is greater than ordinary steels, and the resin used is corrosion and weather resistant. These profiles are an excellent alternative to steel and plastic for all kinds of environments. Pultruded FRP profiles are widely used in many fields as posts, brackets, supports, reinforcement bars, channels etc. According to the requirements of our clients, we can produce different profile designs.

Characteristics of Pultruded Profiles
Pultruded products characteristically are of high strength, light weight, corrosion proof and with excellent insulation properties. This enables a wide range of applications such as the manufacturing of tool handles, ladders for electricians, chemical industry platforms, guardrails, bridges and various construction site needs. We now have a wide range of section bars, such as square tubes, rectangular tubes, round tubes, round rods, I -beams, angle bars and channel sections. Additionally we can also custom make special section bars.
BENEFITS:
Corrosion and chemical resistant Anti-aging
High strength-to-weight ratio
Fire retardant Safety
Ergonomic
Low maintenance
Comprehensive economical efficiency

Specifications of Main Pultruded FRP Profiles:
Pultruded FRP profiles are made by a continuous pultrusion process. Pre-selected reinforcement materials, such as fiberglass roving, mat, woven fabrics or stitched fabric, are drawn through a resin bath in which all materials are thoroughly impregnated with a liquid thermosetting resin. Typical resins include polyester, vinyl esters and phenolic. Any constant cross-section profiles can be pultruded. Pultrusion allows the designer to customize the selection of the resin system, the type and form of fiberglass reinforcements, and the placement of the reinforcements within the composite profile. Typical pultruded profiles include FRP Angle, Square Tube, I Beam, Channel, Round Rod, Round Tube, T Beam, etc. They are widely used as handrails, supports, beams and other structural members in chemical and power industries infrastructure, etc.
