Composite pipe bridge guardrails with optional materials, thickened columns, and impact resistance. Longbang Traffic Facilities
Optional materials: Composite pipe bridge guardrail with thickened columns, strong impact resistance. Guanxian Longbang Traffic Facilities Co., Ltd. offers urban landscape and river channel guardrails with a granite base of 60×40×20 cm and weighing 130 kg. The cast iron columns are lined with steel bars. The surface is hot-dip galvanized and electrostatically sprayed with black matte paint. At the hydrophilic platform, the guardrail is reduced to 1 meter and equipped with benches. It costs about 3000 yuan per meter. The garden landscape guardrail pursues harmonious coexistence with the natural environment and often adopts the form of dry-laid rubble low walls with a height of 40 - 60 cm, which has the functions of defining space and providing seating. Local river pebbles or mountain boulders are selected as the rubble, with a well - arranged mix of sizes. The gaps are filled with gravel or planted with drought - resistant plants such as moss and sedum. The top of the wall is paved with anti - corrosion wooden boards with a width of 30 cm to form a natural seat. This kind of guardrail is low - cost, eco - friendly, and in line with the artistic conception of the landscape garden, and is widely used in parks and green spaces.
Optional materials: Composite pipe bridge guardrail with thickened columns, strong impact resistance. Guanxian Longbang Traffic Facilities Co., Ltd. offers rural river channel guardrails with pre - cast reinforced concrete columns of 12×12 cm and a height of 1.5 meters, equipped with 4 steel bars of 12 mm. The wire mesh has a pore size of 5×5 cm and a wire diameter of 3 mm. The C20 concrete foundation is 40×40×50 cm. It costs about 200 yuan per meter. The height and form of the landscape guardrail in the historical block need to be strictly controlled, generally not exceeding 0.8 meters, and it adopts an antique cast iron style. The cast iron parts are made by the lost - foam casting process with delicate patterns, and the surface is aged to show the traces of time. The color of the guardrail is matte black, consistent with the color of the doors and windows of historical buildings. The column foundation is built with blue bricks, coordinated with the paving in the block. In front of the cultural relic protection units, the guardrail is set as movable and can be temporarily removed during major events. This kind of guardrail is low - key and does not overshadow the main part, integrating into the historical environment.
Optional materials: Composite pipe bridge guardrail with thickened columns, strong impact resistance. Guanxian Longbang Traffic Facilities Co., Ltd. offers sound - absorbing guardrails with metal plates filled with rock wool, and the noise reduction coefficient NRC reaches 0.8. With a height of 2.5 meters, it can effectively block traffic noise. The surface is micro - perforated for sound absorption. The H - shaped steel columns are spaced 2 meters apart and are widely used on both sides of the road. The anti - terror bridge guardrail is designed for attack risks. An explosion - proof steel cable is installed inside the guardrail columns. When the abnormal acceleration and impact of a vehicle are detected, the steel cable will be tensioned instantly to form a blocking net. The steel cable has a diameter of 12 mm and a breaking tension of 180 kN, and the tensioning time is 0.2 seconds. The sensor uses dual - mode radar and infrared detection, and the false alarm rate is less than one in a million. The control system is independently powered, and the backup power supply can work continuously for 72 hours after a power failure. This kind of guardrail has been applied on bridges near important government agencies, greatly improving the safety protection level of key areas.
