National standard safety guardrails for viaducts. Guaranteed quality, source factory, long service life. Longbang Traffic Facilities
National standard safety guardrails for viaducts. Guaranteed quality, source factory, long service life. Longbang Traffic Facilities The guardrails for cross-sea bridges adopt triple anti-corrosion measures: 120 microns of thermal sprayed aluminum, 80 microns of micaceous iron oxide, and 60 microns of polyurethane fluorocarbon. The total film thickness exceeds 260 microns. A rubber water stop is added in the splash zone. The inner cavity of the column is filled with polyurethane foam to prevent condensed water, and a removable inspection cover is set on the top. The guardrails in the river fishing area are equipped with fishing rod brackets and seats on the basis of ordinary guardrails. The brackets are made of stainless steel and can be rotated to adjust the angle to fit fishing rods of different lengths. The seats are made of anti-corrosion wood, 40 cm wide, with backrests. The height of the guardrails in this area is reduced to 0.9 meters for the convenience of anglers' operation. A fishing position is set every 2 meters, and partitions are set between the fishing positions to avoid fishing line entanglement. Fish guard hooks and bucket holders are set under the guardrails. This professional design enhances the fishing experience and attracts a large number of fishing enthusiasts.
National standard safety guardrails for viaducts. Guaranteed quality, source factory, long service life. Longbang Traffic Facilities The titanium alloy of the hot spring river guardrails has a melting point of 1,668 degrees Celsius and extremely strong corrosion resistance. The pipe wall thickness is 2 mm, and the tensile strength is 900 MPa. Argon arc welding with X-ray flaw detection is used. The handrail is wrapped with a heat-insulating sleeve to prevent scalding. It costs more than 10,000 yuan per meter and is used in high-end resort areas. The landscape guardrails at airport aprons need to meet the control requirements. The height shall not exceed 1.2 meters. They are made of fragile materials to prevent the generation of debris when the aircraft accidentally collides. The guardrails are made of foam aluminum with a density of 0.4 g/cm³ and a compressive strength of 5 MPa. After impact, they will be crushed into fine particles. The color is eye-catching orange, and the surface is coated with high-brightness reflective paint. The columns are made of fiberglass, which will break brittlely without producing sharp edges. The guardrail foundation uses a quick-release ground anchor for convenient temporary displacement. This kind of guardrail sacrifices strength for safety, which is a special safety requirement.

Longbang Traffic Facilities The gabion cages of the ecological revetment guardrails are 2×1×0.5 meters and filled with pebbles. The steel wire diameter is 3 mm and is coated with Galfan. The porosity is 30%, which is beneficial to the growth of aquatic plants. The top is covered with concrete. It costs about 800 yuan per meter and is easy to maintain. The landscape guardrails around sports stadiums need to have anti-climbing function. The top is designed with a spearhead style, with the spikes being 15 cm high and the spacing being 10 cm. The height of the guardrail is 2.5 meters. The columns are square steel pipes of 80×80 mm, with a wall thickness of 3 mm and a spacing of 3 meters. The mesh is made of diamond wire mesh with a hole size of 50×50 mm and a wire diameter of 4 mm. The surface is hot-dip galvanized and then sprayed with dark green paint to blend in with the surrounding greenery. An electric sliding door is set at the entrance and exit, and access is allowed through card swiping or face recognition. This kind of guardrail combines safety and aesthetics and effectively prevents illegal intrusion.
