Fire-retardant Fiber Reinforced Polymer Grating

Fire-retardant FRP grating (Fire-retardant Fiber Reinforced Polymer Grating), developed through advanced materials science and precision manufacturing, has become a core solution for demanding engineering environments.

Outstanding Fire Resistance — Your First Line of Safety Defense

Incorporating a composite fire-retardant system of aluminum hydroxide, brominated flame retardants, and modified resin matrix, the product meets the UL94 V-0 standard with a Limiting Oxygen Index (LOI) ≥ 32%. When exposed to open flames, a dense char layer forms on the surface, effectively blocking heat and flame spread. Once the fire source is removed, the grating self-extinguishes rapidly, greatly reducing fire risk. It provides reliable safety protection for hazardous environments such as petrochemical plants, power facilities, and underground utility tunnels.

High-Strength Composite Structure — Stable and Reliable Load Bearing

Reinforced with E-glass fiber and designed with a bidirectional orthogonal layering structure, the grating forms a robust 3D structure. Certified tests show tensile strength ≥ 500 MPa, flexural strength ≥ 400 MPa, and compressive strength ≥ 250 MPa, far exceeding traditional steel and plastic grating. Even under extreme temperatures from -40°C to 120°C, it maintains excellent mechanical performance, ensuring long-term stability for industrial platforms and offshore facilities

All-Weather Corrosion Resistance — Long-Lasting and Maintenance-Free

Thanks to the chemical inertia and anti-permeability of vinyl ester resin, the grating resists strong corrosive agents such as sulfuric acid, hydrochloric acid, and sodium hydroxide. In salt spray tests (ASTM B117) exceeding 5000 hours, no visible corrosion is observed. Without the need for additional coatings, it performs exceptionally in harsh environments like chemical wastewater treatment plants, landfills, and coastal structures. Service life exceeds 30 years, significantly reducing lifecycle maintenance costs compared to metal alternatives.

Modular Design — Efficient and Precise Installation

Following modular engineering principles, the grating is produced in standardized sizes, with each panel weighing only 1/4 the weight of steel grating, greatly reducing lifting and transportation effort. Paired with a snap-lock connection system, it requires no welding or heavy equipment, boosting installation efficiency by over 60%. With an open area ≥ 50% and anti-slip surface rated R11, it ensures fast drainage and slip resistance, meeting OSHA safety standards for workplace and construction safety.
