Municipal road guardrails are also known as urban traffic galvanized spray coated steel guardrails.
It is beautiful, innovative, easy to install, safe and reliable, and has a favorable price. It is applicable to the isolation of urban traffic arteries, highway median greenbelts, bridges, second-class highway, township roads and toll gates of various highways.
Municipal guardrails are currently one of the most popular road isolation guardrails both domestically and internationally.
Mainly used for site isolation belts, municipal engineering isolation belts, and garden guardrails. Isolation and protection of parks, lawns, zoos, lakes, roads, and residential areas in municipal construction; Protection and decoration of hotels, restaurants, supermarkets, and entertainment venues.
The central isolation barrier in municipal guardrails mainly serves to separate opposing lanes and provide warning and protection.
The mechanical and non mechanical isolation barriers mainly separate the motor vehicle lane from the non motor vehicle lane, while the pedestrian barrier mainly separates the motor vehicle lane from the sidewalk, reducing and preventing accidents and ensuring everyone’s safety. At the same time, many places have installed municipal guardrails with regional cultural characteristics, which play a good role in beautifying the city and promoting urban culture!
Municipal guardrails are a type of municipal facility that we often see, but we don’t know much about the specific parameters and uses of this type of municipal facility.
We just think that this type of guardrail has a certain degree of aesthetics, strength, and impact resistance. Everyone thinks that this type of guardrail is not a big deal. In fact, this type of guardrail has been carefully designed to meet the corresponding requirements in terms of performance parameters, otherwise it cannot be put into specific use. Therefore, we will briefly introduce the common parameter characteristics of the guardrail’s use.
The most common type of municipal guardrail is the blue and white version.
The common parameters for this type of guardrail are a height of 1.2 meters and a length of 3.08 meters. In addition, there are also 0.8 meters and 1 meter high ones. This type of guardrail has good anti-corrosion performance and is very easy to install. It is widely used in municipal roads in many cities, serving both as a barrier and a decorative effect.
One of the most common types of municipal guardrail products is the guardrail net.
Northerners like to call it this name, but friends in the south generally refer to it directly as the enclosure fence. This type of guardrail is more commonly used in airports or sports stadiums. According to its desired specific form, it can be divided into different mesh structures such as wave mesh or frame mesh. Its parameters mainly have two aspects. The first parameter is the mesh aperture. Nowadays, most mesh apertures are 75150, and the frame parameters are mainly 20301.5, which are more commonly used.
Another type of guardrail is a triangular guardrail, with a size of 50180.
If it is a triangular guardrail with columns, the size is generally 2.32.9. Its main feature is its good strength, and the rigidity of this guardrail is also very good. In terms of appearance, it not only serves as a barrier or obstruction, but also does not have to worry about affecting the vision. You can directly see the opposite scene through the guardrail, which is often used in some traffic tunnels that need to be closed. This product can be processed through certain techniques to give it different colors or shapes, such as some being yellow, while others are green or red.
Zinc steel guardrails, also known as wrought iron guardrails, are made of galvanized pipes and coated with paint on the surface.
They have won people’s love for their strong corrosion resistance and beauty. There are generally two types of installation methods for zinc steel guardrails as fence protection: pre embedded installation and tray installation. Pre embedded installation requires advance preparation or the use of direct drilling methods for installation. Regardless of which method is used, cement slurry must be poured into the column to fill the gaps and prevent the guardrail from shaking.
Tray installation is carried out by inserting expansion bolts into flat ground, brick walls, and other surfaces. The key to this installation is to level and maintain a consistent line during installation. There are many application scenarios for zinc steel guardrails, which can be used for municipal road barrier protection, beautification protection, factory barrier, airport barrier enclosure, station personnel diversion, etc. What’s remarkable is that zinc steel guardrails provide an ideal solution for wall protection.
The primary use of zinc steel guardrails is for fence protection, and the main stream in fence guardrails is also for it, so zinc steel guardrails are fence guardrails.
In the 1990s, the walls of residential areas, campuses, factories, etc. were mostly brick walls or concrete walls. Although the walls were reinforced, they took up a lot of space, had poor visual appeal, were time-consuming and difficult to construct, and could not be recycled or reused. These defects gradually emerged with the use of these walls, especially with the change in people’s aesthetics. Diversity and beauty have become increasingly important, and old walls are no longer popular.
In the late 1990s, with the rise of iron fences, wall guardrails emerged. Initially, they were cast iron fences with painted surfaces. However, due to their heavy weight, production, transportation, installation, price, and corrosion resistance, their use gradually decreased and they were later abandoned by users.
Gradually replaced by simple and inexpensive zinc steel guardrails, this type of zinc steel fence guardrail uses two layers of anti-corrosion treatment on the inside and outside, and the color of the exterior can also be freely selected, greatly improving its beauty. It is also very easy to install, directly assembled on site, saving a lot of transportation costs. The ultra-high cost-effectiveness has won the love of a large number of customers.
When sound waves encounter sound barriers during propagation, three phenomena occur: reflection, transmission, and diffraction.
Usually, barriers can prevent the propagation of direct sound and provide sufficient attenuation for transmitted sound, while the impact of transmitted sound can be ignored. Therefore, the sound insulation effect of a sound barrier can generally be expressed in terms of noise reduction, which reflects the two abilities of the sound barrier to shield and transmit sound.
Insert a sound barrier between the sound source and the receiving point, with an infinite length, so that sound waves can only diffract from above the barrier and form a sound shadow zone behind it, just like a shadow formed by an object blocking light. In this sound shadow area, people can feel that the noise has significantly decreased, which is the noise reduction effect of the sound barrier.
The height of the sound barrier is between 1m and 5m, covering an effective area with an average noise reduction of 10-15dB (125Hz-4000Hz, 1/3 octave band), up to 20dB. Generally speaking, the higher or farther away the sound barrier, the better the noise reduction effect.
