Pedestrian-only pultruded grating is a composite grating panel made through a professional pultrusion process. The principle involves impregnating reinforcing materials such as continuous glass fiber rovings with thermosetting resin, which is then shaped and cured in a heated mold to form "I" or "T" shaped load-bearing profiles. These profiles are then assembled into a grating using solid tubes/rods as connecting rods. This process ensures the continuous distribution of glass fibers within the profile, significantly improving longitudinal load-bearing performance. Compared to molded grating, it has stronger load-bearing capacity, higher dimensional stability, and is more flexible in processing, allowing for customized cutting and installation as needed.
Advantages
Safety is the primary requirement for pedestrian walkways. Pedestrian-only pultruded grating provide double protection through special design and material properties. Their surface typically features embedded silicon carbide particles, creating a non-slip texture that effectively prevents slips and falls even in oily or wet environments, significantly reducing the risk of accidents. At the same time, these gratings possess excellent electrical insulation properties and do not generate friction sparks. When used in power facilities, flammable and explosive environments, and other special locations, they provide additional safety protection for pedestrians and workers. Some products also meet relevant flame retardant standards, further enhancing safety in high-risk environments.
Easy installation, cost reduction, and improved efficiency. Pedestrian pultruded gratings weigh significantly less than galvanized steel gratings, while their tensile strength is comparable to steel, and their fatigue resistance is superior. The lightweight design significantly reduces transportation costs, and installation can be completed manually, making them suitable for complex construction scenarios such as high-altitude and confined spaces, thus shortening construction time. The high-strength characteristics support larger spans, reducing the need for support structures and further lowering overall project costs.
The production process of Pedestrian-only pultruded grating generates almost no pollution, and the glass fiber in the raw materials is recyclable, aligning with modern green and environmentally friendly concepts. Furthermore, they come in a variety of colors and can be customized according to project requirements, perfectly integrating into various environments such as industrial plants, public venues, and landscape walkways, enhancing the aesthetics of the scene. The grating's open structure also provides excellent drainage and ventilation, preventing water accumulation during rainy days and further improving the user experience.
• Clean the base surface before installation, ensuring it is flat and free of debris;
• Use special connectors for splicing; provide temporary fixation for high-altitude/suspended installations;
• Leave expansion gaps according to ambient temperature differences;
• After completion, check for flatness and load-bearing stability, ensuring there is no shaking or abnormal noise.
Under the guidance of green and low-carbon development, the environmentally friendly characteristics of pedestrian pultruded gratings align with multiple industry policies. In China, there is a strong push to promote green building materials in the infrastructure sector. This grating product is manufactured with low pollution and uses recyclable raw materials, meeting relevant standards and being included in green building material recommendation catalogs in many regions. Furthermore, policy requirements in key anti-corrosion sectors such as chemical and marine industries demand improved corrosion resistance levels for facilities, and its strong anti-corrosion performance meets these needs, making it a preferred material for industry upgrades.
FAQ
Q: How should I choose the surface anti-slip treatment for Pedestrian-only pultruded grating?
A: The selection should be based on the required level of anti-slip performance in the usage environment: For ordinary dry sidewalks, a gritted surface is recommended for better cost-effectiveness; for wet areas with a small amount of oil (such as kitchen back passages and sewage treatment plant walkways), a corrugated surface is recommended for better drainage and anti-slip effect; for areas with more oil and extremely high anti-slip requirements (such as chemical workshops and gas station pedestrian areas), a composite pattern design with diamond-shaped protrusions and striped grooves is recommended for more stable anti-slip performance.
Q: Can Pedestrian-only pultruded grating be customized according to on-site dimensions? What should I pay attention to during installation?
A: They can be fully customized. The pultrusion molding process supports cutting and splicing according to actual on-site dimensions, and can also be customized according to the shape of the passage (such as curved or irregular shapes). Installation precautions: First, ensure that the support frame is flat and firm, and that the grating is tightly fitted to the support points after laying to avoid uneven stress caused by suspension; second, the installation fasteners (such as clips and bolts) should be made of corrosion-resistant materials (such as stainless steel or fiberglass) to match the grating material; third, a special cutting tool should be used during cutting to avoid resin aging caused by high-temperature cutting, and a special sealant can be applied to the cut edges to prevent moisture penetration.
Q: Can the flame retardant performance of Pedestrian-only pultruded grating meet the requirements for use in public areas?
A: Yes, it can. By adding special flame retardants during the production process, the flame retardant performance of pedestrian pultruded gratings can reach high-level international and domestic standards. The oxygen index far exceeds the B1 flame retardant requirements, and it can effectively inhibit flame spread and reduce smoke generation, complying with fire safety regulations in public areas such as shopping malls, hospitals, and schools. When selecting, you can request the supplier to provide the corresponding flame retardant performance test report to ensure product compliance.
