Longbang Traffic Facilities, a direct - supply manufacturer of national standard landscape overpass railings, offers customized road products. The intelligent charging guardrail posts are integrated with USB charging ports and wireless charging boards, with a power of 15 watts. The outdoor waterproof rating is IP65. It can be used by scanning the code for payment, following the sharing economy model, which solves the problem of outdoor emergency charging. The photovoltaic bridge guardrail uses the sunny side of the guardrail to lay flexible solar panels, with a conversion efficiency of 22%. The daily power generation per meter of the guardrail is about 0.5 kWh. The electric energy is stored in the energy storage cabinet at the bottom of the bridge for the use of bridge lighting, monitoring and other equipment, and the surplus electricity can be connected to the power grid. The solar panels are encapsulated with ETFE film, with a light transmittance of 95%, a weight of only 2.5 kg/m², and a bending radius of up to 100 mm to adapt to the curved surface of the guardrail. The self - cleaning coating on the surface uses rainwater to wash and maintain the light transmittance. After dust accumulation, the power generation efficiency drops by no more than 5%. This kind of guardrail realizes the energy self - sufficiency of infrastructure and is a typical practice of the carbon - neutral goal.

The Japanese dry - landscape guardrail is a bamboo fence made of three - year - old osmanthus bamboo with a diameter of 3 - 5 cm, which is smoked to prevent insects and woven in a diamond pattern with a spacing of 2 cm. The Chinese fir posts are coated with tung oil for corrosion prevention, and the bottom pebble water - dispersing belt is 30 cm wide. The bamboo materials are replaced about once every five years. The river ice protection guardrail is set up in cold northern regions. It uses a triangular - section steel guardrail with the sharp corner facing the water flow direction to break the ice floes and reduce the impact force. The height of the guardrail is 1.5 meters, and the post spacing is 1 meter, using an H - shaped steel section. In sections with severe ice floes, ice - breaking cones are added in front of the guardrail. The height of the cones is 2 meters, and they are arranged at intervals of 2 meters. A buffer spring is set between the ice - breaking cones and the guardrail to absorb the impact energy of the ice floes. Before the beginning of spring every year, check whether the guardrail has frost - heave deformation and repair the damaged parts in time. This kind of guardrail can effectively protect the safety of downstream bridges and sluice dams.
