The physical factory of non-standard landscape bridge guardrails has excellent craftsmanship. Longbang Traffic Facilities
Non-standard landscape bridge guardrails are produced by a physical factory with excellent craftsmanship. Guanxian Longbang Traffic Facilities Co., Ltd. offers detachable standard sections for river dredging access road guardrails. Each section is 3 meters long and connected by pins, and fixed with flange plates and anchor bolts. The guardrail is 1 meter high with a 30 cm clearance at the bottom. It is made of Q235B steel with hot-dip galvanizing and can be temporarily removed during dredging and restored after completion. The guardrails of steel truss bridges are often integrated with the main truss structure, using the truss chords as the support framework for the guardrails to achieve the unity of structure and aesthetics. The guardrail grid is composed of welded rectangular steel tubes. Full penetration welds are used at the nodes and inspected by ultrasonic flaw detection to ensure that the fatigue life meets the 100-year service requirement. To reduce the self-weight, the guardrail panels are made of aluminum alloy honeycomb panels with a core material thickness of 15 mm and a surface layer of 0.8 mm. The weight is only 1/3 of that of a steel plate of the same thickness. At the node connections, special stainless steel hinges allow the guardrail to expand and contract freely with temperature changes, with a sliding amount of up to ±20 mm. In addition, a drip edge is set at the bottom of the guardrail to guide rainwater away from the welds and avoid corrosion caused by water accumulation.
Non-standard landscape bridge guardrails are produced by a physical factory with excellent craftsmanship. Guanxian Longbang Traffic Facilities Co., Ltd.'s cultural relief guardrails are prefabricated with GRC. The relief depth is 2 - 5 cm and the flexural strength is 12 MPa. The area of the relief does not exceed 40% of the surface area. The relief is inspired by local allusions such as the dragon pattern on the Zhaozhou Bridge. Each piece has a number on the back for easy replacement. The river guardrails beside the ancient city wall ruins need to be coordinated with the style of the city wall. Terracotta railings in the color of city bricks are used, and the surface is aged to imitate the texture of the ancient city wall. The terracotta railings are fired at a temperature of 1200 degrees Celsius, with a compressive strength of 50 MPa and a water absorption rate of ≤8%. The railing shape imitates the stone railings of the Ming Dynasty. The balustrade is carved with scroll grass patterns, and the capitals of the balusters are lotus seats. During installation, the traditional mortise and tenon structure is used, and tung oil mortar is used for caulking. The guardrail foundation is hidden underground to avoid damaging the ruins' appearance. Each terracotta railing has an antique mark, integrating seamlessly with the ancient city wall.
Non-standard landscape bridge guardrails are produced by a physical factory with excellent craftsmanship. Guanxian Longbang Traffic Facilities Co., Ltd.'s weathering steel guardrails use the dense oxide layer on the surface for corrosion protection without painting, reducing the full-life cycle cost by 30%. The yield strength of Q355NH is 345 MPa. The initial reddish-brown color gradually turns dark brown. In polluted areas, regular flushing is required to promote uniform rusting. The barrier-free ramp guardrails in the river need to be inclined synchronously with the ramp. The inclination angle of the handrail is the same as that of the ramp, and the height is always maintained at 0.85 meters. The handrail extends horizontally by 30 cm at both ends for wheelchair users to grasp and stand up easily. The spacing between the guardrail columns is 1.2 meters, and the foundation is cast integrally with the ramp. The handrail surface is wrapped with anti-slip material, with a diameter of 35 mm and a comfortable feel. At the start and end of the ramp, Braille signs are set on the guardrail to indicate the slope and length information. This meticulous design reflects respect and care for the disabled.
