Galvanized and powder - coated overpass guardrails with thickened columns have a long service life. Longbang Traffic Facilities. The colored bridge guardrails are powder - coated with RAL color cards, offering thousands of colors to choose from, with a color difference ΔE ≤ 1.5. The super - weather - resistant polyester resin has a gloss retention rate of ≥ 80% after 3000 hours of aging. Light - colored systems can reflect 60% of solar radiation, reducing the temperature by 15 - 20 degrees Celsius. Color zoning aids in lane recognition. Each column of the river QR - code guardrail is inlaid with a stainless - steel QR - code nameplate. Scanning the code can provide detailed information about the river section, including: the name and phone number of the river chief, water quality indicators, historical water levels, introductions of surrounding scenic spots, rescue phone numbers, etc. The background management system can update the content and issue flood - control warnings, activity notices, etc. The QR - codes are laser - engraved with a weather resistance of over 10 years. This smart guardrail opens up an information interaction channel between people and rivers, enhancing the public's enthusiasm for river protection. Currently, it has been promoted in many places across the country, with a cumulative installation of over 100,000 columns.

The urban viaduct guardrails use aluminum alloy hollowed - out carvings combined with LED light strips, which not only ensure safety but also enhance the skyline's recognizability. Engineers optimize the column spacing through finite element analysis, so that the guardrail can control the deformation within 50 cm after being hit by an 80 - ton truck. The expansion joints use a sliding structure to avoid temperature stress. The flood - control embankment guardrails need to balance the dual functions of flood - control passage and safety protection. The bottom of the guardrail is equipped with reversible steps. Usually, they are retracted as a guardrail, and during the flood season, they are put down to form an emergency rescue passage. The steps are made of aluminum alloy, 60 cm wide, with a bearing capacity of 300 kg/square meter. The turning mechanism is a stainless - steel hinge plus a spring pin. The height of the guardrail is 1.3 meters, and there is a handrail at the top for flood - control personnel to hold. At key nodes such as sluice gates and pumping stations, the guardrail is provided with a quick - disassembly section, connected by bolts. Two workers can remove a 10 - meter - long guardrail section within 5 minutes to open up a passage for the transportation of emergency rescue supplies.
Galvanized and powder - coated overpass guardrails with thickened columns have a long service life. Longbang Traffic Facilities. The suspension bridge uses steel - strand flexible guardrails. The steel wire rope has a diameter of 19 mm and a breaking tension of 250 kN, passing through the pulleys at the end of the columns and swinging with the bridge deck. The spring base of the column can tilt back 25 degrees during impact to absorb kinetic energy and then automatically reset. The tension is adjusted once a year to ensure the deviation does not exceed 5%. The barrier - free ramp guardrails along the river need to incline 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 two ends of the handrail extend horizontally by 30 cm, making it convenient for wheelchair users to hold and stand up. The spacing between the guardrail columns is 1.2 meters, and the foundation is integrally poured with the ramp. The surface of the handrail is wrapped with anti - slip material, with a diameter of 35 mm and a comfortable feel. At the start and end points of the ramp, the guardrail is provided with Braille signs indicating the slope and length information. This meticulous design reflects respect and care for the disabled.
