Taiping Fiber Reinforcement Trays are composed of continuous glass fibers embedded in a polymer resin, with a pultruded cross-sectional structure reinforced by internal stiffeners for high strength and durability.

Core Composition

The tray is made from Fiberglass Reinforced Plastic (FRP), which combines continuous glass fibers with a polymer matrix such as epoxy or polyester resin. The fibers provide longitudinal tensile strength, while the resin binds the fibers, protects them from environmental damage, and transfers loads between fibers, ensuring structural integrity under mechanical stress .

Cross-Sectional Design

Taiping trays typically adopt ladder-type, tray-type, or trough-type cross-sections. The internal structure often includes stiffeners strategically placed to enhance bearing capacity and prevent deformation under heavy cable loads. This design ensures that even under impact or vibration, the tray maintains its shape and protects the cables inside .

Reinforcement Layout

• Longitudinal fibers run along the length of the tray to resist tensile forces.
• Transverse fibers or mesh layers may be incorporated to improve bending resistance and distribute loads evenly.
• Internal stiffeners act as secondary reinforcement, increasing rigidity and preventing sagging over long spans .

Functional Components

The tray system includes modular components such as straight sections, elbows, tees, and crosses, allowing flexible installation in complex layouts. End caps, couplers, and side channels are integrated to secure the tray and maintain alignment. T-bolts and brackets are used to fasten components while keeping the internal fiber structure intact .

Surface and Environmental Protection

The tray surface is often treated with UV-resistant coatings, flame retardants, or anti-slip finishes to enhance durability, fire safety, and resistance to harsh environments. This ensures long-term performance in corrosive or outdoor settings, such as chemical plants, coastal areas, or substations .

Mechanical Properties

• Longitudinal tensile strength: >300 MPa
• Transverse bending strength: >200 MPa
• Density: 1.8–2.1 g/cm³, making it lightweight yet strong
• Load capacity: Standard 300 mm trays can support up to 200 kg/m static load In summary, the internal structure of Taiping Fiber Reinforcement Trays is a carefully engineered combination of continuous glass fibers, polymer resin, and internal stiffeners, designed to provide high strength, corrosion resistance, and modular flexibility for industrial cable management applications.
