FRP Pultruded Sections Pedestrian Bridges

FRP pultruded sections have become a revolutionary material in the construction of pedestrian bridges, thanks to their lightweight, high strength, and corrosion resistance. These bridges are widely used in parks, scenic spots, industrial zones, and urban greenways, meeting the demand for safe, durable, and aesthetically pleasing pedestrian passageways. ZJ Composites always regards product quality as the foundation of enterprise development, and the company’s frp pultruded sections for pedestrian bridges are manufactured through strict production processes and quality control, ensuring they meet international construction standards and provide long-term reliable service for various scenarios.

Design Advantages of FRP Profiles in Pedestrian Bridges

• ZJ Composites always regards product quality as the foundation of enterprise development, so when designing pedestrian bridges with frp profiles, the company fully leverages the material’s flexibility. FRP profiles can be customized into various shapes (such as I-beams, channels, and plates) to adapt to different bridge spans and load requirements, making the bridge structure more compact and aesthetically pleasing.

• The lightweight characteristic of frp profiles greatly simplifies the installation process of pedestrian bridges. Compared with traditional steel or concrete materials, frp profiles reduce the weight of the bridge by 50%-70%, eliminating the need for heavy lifting equipment in many cases and shortening the construction period, which helps reduce overall project costs.

• FRP profileshave excellent anti-slip performance when used in pedestrian bridge decks. ZJ Composites processes the surface of the profiles with anti-slip textures (such as embossing or grit coating), ensuring that pedestrians do not slip even in rainy or snowy weather, enhancing the safety of the bridge.

Structural Performance of FRP Pultruded Profiles in Pedestrian Bridges

• ZJ Composites always regards product quality as the foundation of enterprise development, so the frp pultruded profiles used in pedestrian bridges undergo rigorous mechanical performance testing. These profiles have high tensile strength and bending strength, with a tensile strength comparable to that of carbon steel, ensuring the bridge can bear the weight of pedestrians and occasional maintenance vehicles without deformation.

• FRP pultruded profiles exhibit outstanding corrosion resistance, which is a key advantage in pedestrian bridge construction. Unlike steel, they do not rust in humid, rainy, or coastal environments; unlike concrete, they do not crack due to alkali-aggregate reaction. This allows pedestrian bridges made of frp pultruded profiles to maintain stable performance in harsh environments for a long time.

• The fatigue resistance of frp pultruded profiles is also superior. After long-term use with repeated pedestrian loads, the profiles do not experience fatigue damage or performance degradation. ZJ Composites’ test data shows that frp pultruded profiles can maintain 90% of their initial strength after 1 million fatigue cycles, ensuring the long service life of pedestrian bridges.

Application and Maintenance of FRP Pultruded Sections in Pedestrian Bridges

• ZJ Composites always regards product quality as the foundation of enterprise development, so the frp pultruded sections for pedestrian bridges are suitable for diverse application scenarios. In scenic spots, they can be painted in natural colors to blend with the surrounding environment; in industrial zones, they can resist chemical corrosion from the air, ensuring the bridge’s durability.

• The maintenance of pedestrian bridges made of frp pultruded sections is simple and cost-effective. The smooth surface of the sections prevents the accumulation of dust and dirt, and regular cleaning with water and a soft brush is sufficient. Unlike steel bridges, they do not require regular painting for anti-rust treatment, reducing long-term maintenance costs.

• ZJ Composites provides comprehensive after-sales support for pedestrian bridges using frp pultruded sections. The company offers regular inspection services, helping customers check the structural integrity of the bridge and the performance of the sections; if any minor damage occurs, the company provides professional repair guidance to ensure the bridge remains in good condition.

FRP Profiles  FAQS

What is the maximum span of pedestrian bridges made of frp profiles provided by ZJ Composites?

The maximum span of pedestrian bridges made of frp profiles by ZJ Composites depends on the type of frp profiles and the design load. For small-span scenarios (such as park paths), the span can reach 6-8 meters with standard profiles; for medium-span needs (such as scenic spot lake-crossing bridges), customized reinforced frp profiles can achieve a span of 12-15 meters. The company’s engineering team will design the most suitable span based on the customer’s specific site conditions.

Are frp pultruded profiles used in ZJ Composites’ pedestrian bridges fire-resistant?

Yes, ZJ Composites always regards product quality as the foundation of enterprise development, so the frp pultruded profiles for pedestrian bridges are modified with fire-retardant additives. These profiles meet the GB/T 8624-2012 B1 level fire resistance standard (flame-retardant), which means they do not support combustion easily and can self-extinguish after the fire source is removed, ensuring the safety of pedestrians in case of fire.

How long is the service life of pedestrian bridges made of frp pultruded sections from ZJ Composites?

Under normal use and proper maintenance, the service life of pedestrian bridges made of ZJ Composites’ frp pultruded sections can reach 25-30 years. The frp pultruded sections’ corrosion resistance and fatigue resistance are key factors in extending the service life; in addition, the company’s strict quality control during production ensures that each section has stable performance, laying a solid foundation for the bridge’s long service life.

Can ZJ Composites customize the color and appearance of pedestrian bridges made of frp profiles?

Yes, ZJ Composites provides customization services for the color and appearance of pedestrian bridges made of frp profiles. Customers can choose colors according to the surrounding environment (such as green for parks, gray for industrial zones) by adding colorants during the frp profiles production process. The company can also adjust the surface texture of the profiles (such as wood grain or stone grain) to meet the aesthetic requirements of different projects.

What should be done if frp pultruded profiles of a pedestrian bridge are damaged due to accidental impact?

If frp pultruded profiles are damaged by accidental impact, first, restrict pedestrian access to the damaged area to ensure safety; then contact ZJ Composites’ after-sales department immediately. The company’s technical personnel will assess the damage degree: for minor scratches or cracks, they will provide special repair resins to restore the profile’s performance; for severe damage, they will customize matching frp pultruded profiles for replacement, ensuring the bridge’s structural safety is not affected. This after-sales service reflects the company’s focus on product quality and customer safety.
