Guocheng hot-dip galvanized highway sign pole cantilever sign pole

Description :

　　1. Road traffic signs are usually set on the right side of the road, in a location that is easy for drivers to see. When setting up road traffic signs on lanes such as overtaking lanes, lanes, and emergency parking belts, it is difficult to do so on the roadside. It is usually set up above the road through a gantry to facilitate driver observation and solve the problem of cantilevered traffic sign poles obstructing each other. Near the end of the highway, some prohibition or warning signs are also placed within the median strip.

　　2. When setting the location of traffic signs, it is important to consider that the signs do not obstruct or affect each other, and are not obstructed by other buildings that obstruct the view of drivers and passengers.

　　3. The setting of road traffic signs such as interchanges and service areas should be based on the principle that vehicles approaching intersections or diverging or merging points will not affect the driver's line of sight.

　　4. The installation of road traffic signs must ensure that drivers have sufficient reaction time to make the necessary judgments for safe operation. Therefore, in order for the content of the logo to play such a role, there should be a certain amount of advance in the setting of the logo. In general, the larger the board size and simpler the content of road traffic signs, the smaller the advance distance of the sign can be.

　　5. Road side traffic signs must ensure a clear distance of 25cm from the outer edge of the shoulder, and a clearance of 2m between the lower edge of the sign board and the outer surface of the emergency stop zone. When setting up signs above the highway, ensure that the clear distance between the lower edge of the sign board and the road surface is greater than 5m.

　　6. The road traffic sign board is arranged at a right angle to the highway and can be slightly tilted inward. The front of the board faces the direction of traffic, making it easy for drivers to observe. There is no unified opinion on the issue of leaning roadside signs in road traffic signs. Some places believe that the signboard should only tilt inward when it is more than 9m away from the edge of the shoulder. When the signboard is less than 9m away from the edge of the shoulder, to prevent glare caused by reflection, it is tilted outward by about 30 degrees.

　　Hot dip galvanizing process

　　Hot dip acid should be used to treat the inner and outer surfaces with corrosion, with a thickness of ≥ 75um in accordance with GB -/T13912-92 standards. The design service life should not be less than 30 years, and the galvanized surface should be smooth and beautiful, with basically the same color. After impact testing, there should be no peeling or flaking. Provide galvanizing inspection report. Traffic sign pole price

　　powder coating process

　　Spraying should use outdoor high-purity polyester plastic powder, with a white color (according to user requirements), stable plastic layer quality, no fading, and no peeling. Strong adhesion, resistant to strong solar ultraviolet rays, UV resistant, suitable for cities along the lake and key saline areas. The designed service life ratio is less than 30 years, and the thickness of the traffic sign pole is ≥ 80um, which meets the standard. Provide a spray coating inspection report. Spray protection requirements: The film thickness should not be less than 40um, with strong adhesion, no peeling, and no detachment. The surface is flat and smooth, and the color is basically consistent.

　　design capability
