Manufacturer of Q235 engineering bridge guardrails with high impact resistance, Longbang Traffic Facilities
Q235 Engineering Bridge Guardrail Manufacturer with High Impact Resistance - Guanxian Longbang Traffic Facilities Co., Ltd. The river channel guardrail posts are inlaid with stainless steel QR code nameplates. Scan the QR code to obtain information about the river chief, water quality and water level, and scenic spot introductions. The laser - engraved QR codes are weather - resistant for over 10 years, and flood - control warnings can be updated in the background. More than 100,000 guardrail posts have been installed in total. The cliff plank road landscape guardrail needs to withstand extreme wind loads and adopts an anchor - cable type flexible protection system. The main cable is made of galvanized steel wire rope with a diameter of 22 mm and a breaking tension of 350 kN, and it is anchored in the rock mass. The secondary cables are spaced 1 m apart with a diameter of 16 mm, forming a mesh - like protection. The height of the guardrail
Q235 Engineering Bridge Guardrail Manufacturer with High Impact Resistance - Guanxian Longbang Traffic Facilities Co., Ltd. The ultra - high manganese steel used in the flood discharge channel guardrail has a hardness of HRC58 - 62, and its wear resistance is 5 times that of ordinary steel. The circular cross - section has a diameter of 89 mm and a wall thickness of 8 mm. Tungsten carbide is surfacing welded on the surface. The posts are spaced 1 m apart with a foundation depth of 1.5 m, and anti - scouring baffles are installed on the outside of the curve. The cross - section of the conical bridge guardrail is a trapezoid that is narrower at the top and wider at the bottom. The angle of the impact - facing surface is 75 degrees, which can decompose the vehicle impact force into horizontal and vertical components, guiding the vehicle to climb upwards and decelerate. The top width is 15 cm, the bottom width is 45 cm, and the height is 1.1 m. Compared with a rectangular cross - section, this shape can reduce the impact deceleration by 30%, reducing the injury to passengers. The concrete grade is C50, the reinforcement ratio is 1.2%, and the crack width is controlled to ≤0.1 mm. Conical guardrails are commonly used on small - radius curved bridges, using the inclined surface to convert centrifugal force into an upward component, improving vehicle driving stability.
Q235 Engineering Bridge Guardrail Manufacturer with High Impact Resistance - Guanxian Longbang Traffic Facilities Co., Ltd. The anti - corrosion wood for the hydrophilic plank road guardrail is CCA - treated scots pine. The posts are spaced 1.5 m apart with a cross - section of 10×10 cm. The 304 stainless steel connectors are installed in a hidden way. The height is 1.05 m, and the handrail width is 6 cm. An arc with a radius of 2 m is set at the corner. The cultural relief bridge guardrail integrates regional cultural elements into the guardrail design, showing historical stories or folk customs through the relief process. The relief depth is 2 - 5 cm, and it is pre - fabricated with GRC (Glass Fiber Reinforced Cement) with a flexural strength of not less than 12 MPa. The pattern design should avoid being too complex to affect the structural stress, and the relief area should not exceed 40% of the guardrail surface area. In historical and cultural cities, the guardrail reliefs are often inspired by local allusions, such as the dragon - patterned guardrail of the Zhaozhou Bridge and the stone - lion guardrail of the Lugou Bridge. Each relief board has a number on the back, which is convenient for replacement and maintenance according to the number in the future.
