Q235 Combined Bridge Guardrail. Customization available from the physical factory of Guanxian Longbang Traffic Facilities Co., Ltd. The detachable standard section of the river channel dredging access road guardrail is 3 meters long and connected by pins. It is fixed with flange plates and anchor bolts. The height is 1 meter, and there is a 30 - centimeter clearance at the bottom. Made of Q235B steel with hot - dip galvanizing, it can be temporarily removed during dredging and restored after completion. The design of the pedestrian overpass guardrail focuses on fall prevention and child safety protection. The net height shall not be less than 1.3 meters, and the spacing between vertical rods must be less than 11 centimeters to prevent children from getting through. The stainless - steel composite pipe guardrail complements the modern architectural style with its mirror - polished effect. Its 304L material can withstand salt - fog corrosion for more than 3000 hours in coastal cities. The handrail part adopts an arc - shaped cross - section design, and the width is controlled between 5 - 7 centimeters, which is convenient for grasping and does not obstruct the view. On the up - and - down slope sections, the guardrail needs to be inclined synchronously with the slope and is provided with double handrails to meet the needs of people of different heights. In terms of night lighting, embedded LED light strips are arranged along the bottom of the guardrail. The illuminance reaches more than 30 lux without glare, ensuring the safety of pedestrians at night.
Q235 Combined Bridge Guardrail. Customization available from the physical factory of Guanxian Longbang Traffic Facilities Co., Ltd. The riverside promenade guardrail has high and low double handrails: the high one is 1.1 meters and the low one is 0.7 meters. The stainless steel is coated with nylon, providing a warm touch. The spacing between H - shaped steel columns is 2.5 meters. The tempered laminated glass panel is 10+1.52+10 millimeters, and there is a 20 - centimeter green belt at the bottom. The guardrail system of mountain canyon bridges faces more severe environmental challenges. The superposition of strong winds, freezing, and earthquake loads requires the guardrail to have an unconventional redundant design. The prestressed reinforced concrete guardrail keeps the concrete in a compressed state through the tensioning of longitudinal prestressed tendons, significantly improving the crack resistance and fatigue life. To deal with the corrosion of steel bars by road deicing agents in winter, the surface of such guardrails is coated with a resin coating and a cathodic protection device is added to control the chloride ion penetration depth within 5 millimeters. At the same time, the drainage holes at the bottom of the guardrail need to be densified to 3 per meter to prevent water accumulation and frost heaving from causing concrete spalling. In areas with an earthquake - fortification intensity of more than 8 degrees, the connecting bolts between the guardrail and the bridge deck use yield - type energy - dissipating components, which undergo plastic deformation before the main structure under earthquake action to consume earthquake energy and protect the safety of the bridge main body.
Q235 Combined Bridge Guardrail. Customization available from the physical factory of Guanxian Longbang Traffic Facilities Co., Ltd. The ecological bridge guardrail is made of recycled plastic and bamboo fiber composite materials, reducing the carbon footprint by 40%. The impact resistance is 30 kJ/square meter. Climbing plants are planted inside the columns and supplied with water through drip irrigation, which can lower the temperature by 3 - 5 degrees Celsius in summer. There are reserved gaps at the bottom for small animals to pass through. The flood - discharge channel guardrail needs to consider the abrasion caused by sediment carried by high - speed water flow. It is made of ultra - high manganese steel with a hardness of HRC58 - 62, and its wear resistance is 5 times that of ordinary steel. The cross - section of the guardrail is round, with a diameter of 89 millimeters and a wall thickness of 8 millimeters. The surface is overlaid with a tungsten carbide wear - resistant layer. The spacing between columns is 1 meter, and the foundation is a reinforced concrete independent foundation with a depth of 1.5 meters. At the curve, an anti - scouring baffle is added on the outer side of the guardrail to prevent water flow from scouring the foundation. This kind of guardrail is expensive, about 5000 yuan per meter, but its service life can reach 50 years, and its comprehensive benefits are better than those of ordinary guardrails that need to be replaced frequently.
