Galvanized highway and bridge guardrails for urban expressways, customized according to drawings by Longbang Traffic Facilities
Galvanized highway bridge guardrails for urban expressways can be customized according to drawings. Guanxian Longbang Traffic Facilities Co., Ltd. offers urban landscape river guardrails with granite bases measuring 60×40×20 cm and weighing 130 kg. The cast iron columns are lined with steel bars. The surface is hot-dip galvanized and electrostatically sprayed with black matte paint. At the hydrophilic platform, the guardrail is lowered to 1 meter and equipped with benches. It costs about 3000 yuan per meter. Cultural relief bridge guardrails integrate regional cultural elements into the guardrail design, showing historical stories or folk customs through the relief process. The relief depth is 2 - 5 cm, prefabricated with GRC (Glass Fiber Reinforced Cement), and the flexural strength is not less than 12 MPa. The pattern design should avoid being too complex to affect the structural stress, and the relief area should not exceed 40% of the guardrail surface area. In historical and cultural cities, the guardrail reliefs are often inspired by local allusions, such as the dragon-patterned guardrails of the Zhaozhou Bridge and the stone lion guardrails of the Lugou Bridge. Each relief board has a number on the back for easy replacement and maintenance in the future.
Galvanized highway bridge guardrails for urban expressways can be customized according to drawings. Guanxian Longbang Traffic Facilities Co., Ltd. offers intelligent bridge guardrails integrated with fiber grating strain gauges with an accuracy of ±1 microstrain and acceleration sensors to identify the impact position. When the temperature and humidity monitoring exceeds 80% for 24 hours continuously, an alarm will be triggered. The data is transmitted to the cloud via 4G, and it is powered by solar energy with a 7-day battery life without sunlight. Photovoltaic bridge guardrails use flexible solar panels laid on the sunny side of the guardrails, with a conversion efficiency of 22%. The daily power generation of each meter of guardrail is about 0.5 kWh. The electricity is stored in the energy storage cabinet at the bottom of the bridge for bridge lighting, monitoring and other equipment. The surplus electricity can be connected to the power grid. The solar panels are encapsulated with ETFE film, with a light transmittance of 95% and a weight of only 2.5 kg/m². The bending radius can reach 100 mm to adapt to the curved surface of the guardrail. The self-cleaning coating on the surface uses rainwater to keep the light transmittance, and the power generation efficiency decreases by no more than 5% after dust accumulation. This kind of guardrail realizes energy self-sufficiency for infrastructure and is a typical practice for the carbon neutrality goal.
Galvanized highway bridge guardrails for urban expressways can be customized according to drawings. Guanxian Longbang Traffic Facilities Co., Ltd. offers river guardrails that primarily prevent people from falling into the water and at the same time meet the flood discharge requirements. The net height on the riverside side is not less than 1.2 meters, and the distance from the bottom to the ground does not exceed 15 cm. The spacing between vertical rods is 11 cm, and the spacing between horizontal rods is 20 cm. When the flow velocity exceeds 2 m/s, the foundation is deepened to 1 meter below the riverbed. The glass bridge guardrails use laminated tempered glass, which consists of two pieces of 5 mm tempered glass sandwiching a 1.52 mm PVB film. The impact resistance is 5 times that of ordinary glass. Even if it breaks, the fragments will stick to the film and will not fall and hurt people. The glass panels can be up to 2 meters × 3 meters in size and are fixed to the columns by stainless steel claw fittings. The claw fittings are cast from 316L stainless steel, with a tensile strength of not less than 520 MPa. The edges of the glass need to be finely ground, with a chamfer width of 2 mm to eliminate stress concentration points. On sightseeing bridges, the glass guardrails have extremely high transparency, with a visible light transmittance of over 91%, providing an unobstructed viewing experience.
