National standard landscape overpass guardrails, quality - guaranteed source factory, protective and beautiful, Longbang Traffic Facilities
National standard landscape overpass guardrails. Quality guaranteed, from the source factory. Protective and beautiful. Guanxian Longbang Traffic Facilities Co., Ltd. River anti-ship collision guardrails. Floating steel anti-collision boxes, 3×1.5×1 meters, filled with closed-cell foam inside. The steel plate is 6 millimeters thick. Red and white warning paint. Connected to the riverbed anchor through chains. The box body deforms to absorb energy and protect the bridge pier. The hydrophilic plank road guardrails adopt a combination of anti-corrosion wood + stainless steel. The anti-corrosion wood is Pinus sylvestris var. mongolica treated with CCA anti-corrosion treatment, and the penetration depth of the preservative is ≥10 millimeters. The distance between guardrail columns is 1.5 meters, with a cross-section of 10×10 centimeters. The crossbeam is 5×10 centimeters, with a spacing of 30 centimeters. All wooden components are painted with two coats of wood wax oil on the surface and need to be repainted once every two years. The stainless steel connectors are made of 304 material, with hidden installation and no exposed screws. The height of the guardrail is 1.05 meters, and the handrail is 6 centimeters wide, providing a comfortable feel. At the corners of the plank road, arc-shaped guardrails with a radius of 2 meters are set to avoid sharp corners from hurting people. This kind of guardrail is warm and natural, and is deeply loved by tourists.
National standard landscape overpass guardrails. Quality guaranteed, from the source factory. Protective and beautiful. Guanxian Longbang Traffic Facilities Co., Ltd. Anti-glare guardrails, specially used for highway median strips. Steel plate punched louver structure. The shading angle is 30 degrees to block the lights of oncoming vehicles. The height is 1 meter with galvanized treatment to ensure night driving safety. The guardrails in the river fishing area are equipped with fishing rod holders and seats on the basis of ordinary guardrails. The holders are made of stainless steel and can be rotated to adjust the angle, suitable for fishing rods of different lengths. The seats are made of anti-corrosion wood, 40 centimeters wide, with backrests. The height of the guardrails in this area is reduced to 0.9 meters for the convenience of anglers to operate. A fishing spot is set every 2 meters, and the fishing spots are separated by partitions to avoid fishing line entanglement. There are fish guard hooks and bucket holders under the guardrails. This professional design enhances the fishing experience and attracts a large number of fishing enthusiasts.
National standard landscape overpass guardrails. Quality guaranteed, from the source factory. Protective and beautiful. Guanxian Longbang Traffic Facilities Co., Ltd. Zigzag guardrails with a folding angle of 150 - 170 degrees. The radius at the turning point is not less than 300 millimeters. Each section is 3 - 6 meters long, continuously welded and then cut into sections. The fluorocarbon spray color changes with the light. The torque effect needs to be considered in the anti-collision calculation to strengthen the cross-section of the columns. The river water level marking guardrails combine the water level gauge with the guardrails. Scales are engraved on the side of the guardrail columns, with a grid of 10 centimeters each. The numbers are printed with luminous paint. The scale range is from the water level to the embankment top elevation, accurate to centimeters. At the same time, an electronic water level gauge is installed, and the data is uploaded to the flood control command center in real time. When the water level exceeds the warning line, the red LED lights on the top of the guardrails flash to alarm, and the broadcast system automatically broadcasts the evacuation notice. This multi-functional guardrail has multiple uses, saving the cost of setting up a separate water level observation station.
