Runzhu outdoor strand woven bamboo highway guardrail includes first-class highway railing and second-class highway guardrail series. It is a new eco-friendly integrated safety & landscape product for road infrastructure, complying with JTG D81 specifications for highway traffic safety facilities. It provides integrated solutions for trunk highways, scenic roads, waterside and cliff roadside sections, combining safety protection and landscape beautification.

Different from conventional steel and concrete guardrails with rusting, heavy weight and poor landscape compatibility, Runzhu adopts self-developed outdoor strand woven bamboo (heavy bamboo) as raw material. Bamboo fiber bundles are processed through high-temperature carbonization, resin impregnation and high-pressure hot pressing. This high-density renewable bamboo composite boasts outstanding mechanical strength. Deep carbonization removes internal nutrients of bamboo, achieving Class 1 decay resistance, mold and termite resistance. It maintains stable dimensions in mountainous, waterside, humid and coastal salt fog environments with low shrinkage and expansion, resisting cracking and deformation. Its outdoor service life exceeds 15 years, greatly cutting maintenance cost and supporting low-carbon transportation infrastructure and “bamboo replacing steel” strategy.

Runzhu second-class highway guardrail is designed for county and township arterial second-class highways with design speed of 40–80 km/h. It mainly serves waterside slopes, village road sections, tourist branch roads and roadside edge protection. Adopting modular assembly structure with strand woven bamboo posts, rails and vertical balusters, it enables fast on-site installation. It provides pedestrian isolation and roadside warning. Natural bamboo grain harmonizes with mountain and rural surroundings, solving the problem of rigid visual effect of traditional steel guardrails. It is ideal for rural revitalization and tourist highway projects.

Runzhu first-class highway railing applies to first-class arterial highways, scenic first-class roads, bridge edges and median landscape sections with design speed of 60–100 km/h. It requires higher structural strength and impact resistance. Thickened high-density bamboo profiles and optimized connection joints improve bending and impact resistance to meet mechanical requirements of first-class highway landscape railings. While guaranteeing safety performance, it reduces rigid industrial visual effect, perfect for scenic corridors, riverside and lakeside first-class road upgrading projects.

All Runzhu strand woven bamboo highway guardrails support customized height, cross-section and carbonized color. Matching metal embedded parts are available for easy connection with existing roadbed and bridge structures. The material is eco-friendly with fast-growing bamboo and excellent carbon sequestration, free of heavy-duty toxic preservatives. Compared with steel guardrails, it avoids rust and repainting work; compared with solid wood, it has superior anti-insect and dimensional stability. Widely used as first-class highway railing, second-class highway guardrail, scenic byway railing, riverside road fence and park arterial road barrier, it integrates safety, durability and ecological aesthetics, becoming an innovative green solution for sustainable transportation infrastructure.
