Street lighting pole plays an important role of the modern city at night, so street lighting design must be considered in many aspects, such as the height, brightness, shape, etc of the street light pole, these all need to be noted. The layout of the street lights must first take into account the functional needs, both to have sufficient illumination and to avoid glare. In order to ensure safety, it is often necessary to repeatedly compare technical and economic indicators to determine the best solution.
Yaolong street light poles, brackets and arms are engineered according to AASHTO standards and accepted commercial criteria. Proper selection for an application is based on information such as EPA, wind zone, applied range, mounting height and other attachments (such as banner arms and flags). This information is necessary to ensure the smooth operation of the project. Upon customer’s request, we will provide design information (such as EPA charts and wind maps, which is as general guidelines only and assumes no responsibility for proper loading analysis and/or product selections. To ensure proper selection of the light pole, luminaire, accessories and/or foundation, Yaolong street light pole suppliers recommend the customer consult a qualified engineer to analyze the loading and design criteria for the specific application. At the meantime, Yaolong light pole can also consult qualified engineers for your customized project at a surcharge.
With the development of modern science and technology, the style of street lamps has become more and more beautiful and the variety is more abundant with the requirements of modern life. Street lamp is widely used in various types of road lighting such as main/sub-main roads, highways, expressway, industrial garden areas, city squares, schools, parks, scenic roads, and rural roads of various types of cities. ; According to different environmental requirements and special requirements of the road light pole material selection is also different.
A.Aluminum street light pole
Most of the aluminum alloy poles used in street lighting are made by spinning technology. The spinning aluminum alloy street light poles are made by 6061/6063 aluminum alloy tube which is high-speed spinning by large diameter numerical control equipment to form tapered or shaped rods. The aluminum alloy pole has the characteristics of good anti-corrosion performance, lightweight, convenient transportation and installation, rich surface treatment and long service life. The conventional height of aluminum road lighting is 5 to 15 meters. Aluminum alloy street light poles are more expensive than other materials because of the relatively complicated process and relatively expensive raw materials.
B.Stainless steel street light pole
The light pole is made of stainless steel and has different grades such as 304 and 316L. The lamp post has a straight diameter straight pole shaft, and there is also tapered pole rolled of stainless steel sheet. Stainless steel street lamp post common height is 6 meters to 12 meters. The thickness is generally 2.5 mm to 4.5 mm, with the characteristics of strong hardness, corrosion resistance, beautiful appearance and high-cost performance.
C.steel street light pole
The steel street light pole is made of carbon steel Q235A steel. Through the Q235 steel plate shearing, rolling, welding and other processes, it is made into a semi-finished lamp post, and then they were treated with acid pickling, hot-dip galvanizing and surface spray or painting to form a finished rod. After the internal and external hot dip galvanized the lamp pole can improve its anti-corrosion performance, but compared with stainless steel street lamps pole and aluminum alloy street lamps post, steel lamp poles have low utilization value, short service life and are easy to rust.
Aluminum street light poles off the advantage of being lightweight, easy to machine and also provide natural rust resistance. These advantages make aluminum a great choice when your project is in wet areas or near water.

The height of the street light pole:
The height of the light pole: the power of the light source has a direct relationship with the height of the light pole. In principle, the higher the light pole, the greater the power of the light source, although a small wattage light source can be installed on a higher street light. Illuminate the ground, but this ratio is not ideal both in terms of brightness and illumination.
Types of light sources:
At present, the light sources used in street lighting can be basically divided into two categories: LED lights and high-pressure sodium lamps. The power of these two lamps is completely different under the same illumination range and the same illumination brightness. We know that LED lamps can be called synonymous with "green energy-saving light source", its energy-saving effect is well known, such as a set of 7-meter-high street light poles, the brightness of a 40W LED lamp head and the brightness of a 110W high-pressure sodium lamp almost the same.
Environment used:
The environment used: Whether it is equipped with high-pressure sodium lamps, metal halide lamps or LED energy-saving lamps. The environmental factors will also affect their power. For example, if the street lamp is installed in the countryside and the city center, even if the two places have the same height of the lamp pole, the configuration of the light source will be completely different. Why do you say this? First of all, the human traffic and traffic volume in the city center is pretty large, and the people there will spend more time walking at night. Thus the requirements are also generally high, and this environment must be installed with a high-power light source. The countryside is different. There are very few people who go out to play at night. A little light can meet the brightness requirements. In this case, the light source with a small power point is no problem, and it is cheap and power-saving.
A.Aluminium alloy street lighting pole raw material
The aluminium street light pole used for spinning is all 6061 or 6063 aluminum alloy pipes of equal diameter. It is an excellent aluminum alloy building profile and is widely used in street lamps, flagpoles, etc., with high wind pressure resistance. , assembly performance, corrosion resistance and decorative properties. In addition, the light pole of aluminum alloy material is light in weight and environmentally friendly.
B.Aluminum street lamp pole formation
The formation of the aluminum alloy light pole body is formed by a large-scale full-CNC spinning device to form a tapered or profiled pole shaft during high-speed rotation, and the formed pole shaft will be polished to remove oil stains, burrs, and indentations on the surface of the pole body. Longitudinal welds are not allowed for all rods. For the sake of beauty, the aluminum alloy pole can also be power coated with other colors according to customer requirements.
C.Welding of aluminum alloy street lamp pole bottom plate
In order to ensure the strength of the aluminum alloy pole base, the aluminum street light pole’s base plate and pole shaft will be carefully and circumferentially welded top and bottom. The base of all aluminum alloy poles is made of 6061 or 6063 aluminum plate stamped by special mold, or A356 pressure casting. The welding of the bottom plate of the shaft is all automatic welding. In this high-quality welding process, the strength and aesthetics of the welding are guaranteed.
D.Aluminum alloy street pole electrical hole
Each aluminum light pole has an electrical hole for the junction box. We use advanced laser cutting machine to cut the door panel of the electrical hole. The door panel is cut from the shaft and is one of part of the pole shaft, so it is tightly fitted, and the gap between the door plate and hatch is less than 0.5mm. After deburring, the edge is smooth, which ensures the waterproofness of the electrical hole. The electrical hole is generally opened 500mm above the bottom of the pole (also according to the shape of the rod). At the rear of the door panel, inside the shaft, an aluminum rail is required to weld the junction box. The door lock uses a special lock with a stainless steel anti-theft screw to lock the door panel. It can only be opened by using the professional tools we provide, thus improving the anti-theft performance of the product.
E.Aluminum alloy street light pole grounding system
The aluminum strip is folded into an "L" shaped workpiece, one side of the workpiece is welded to the inner wall of the rod, and the other side is opened with a hole of M8 for grounding the wire.
F.Aluminum alloy street light pole strength treatment
The aluminum products processed by the aluminum alloy pipe factory are further annealed by the furnace to obtain the T0 state, also named the annealing state. In order to make the aluminum alloy poles have the strength of steel, all of our aluminum alloy poles must be quenched and aging to reach the T6 state to meet the international strength standards of aluminum rods.
G.Aluminum alloy street light pole surface treatment
1.Aluminum light pole clear anodized
Anodizing is an electrochemical process that produces an oxide layer on the surface of a metal by electrochemical means. The light pole is immersed in a cleaning and pretreatment tank prior to immersing the product in an acidic electrolyte bath. The current releases oxygen ions through the material that combines with the aluminum atoms at the surface of the component to increase the thickness of the native oxide layer on the aluminum. The thickness of the oxide layer is available in several different sizes, depending on the location of the installation and the local environment. After anodizing, the product forms a 20μm closed film layer to ensure the corrosion resistance of the lamppost in any natural environment, and to ensure that the rod has no obvious discoloration within 25 years. Unlike other coating options, this anodic oxide structure is fully integrated with the underlying substrate so it does not chip or flake off.
2.aluminum alloy street lamp post color
A.Aluminum alloy street light pole chemical coloring
The chemical coloration of aluminum and aluminum alloys is mostly carried out on an anodized film. There are few methods for chemical coloring directly on the surface of aluminum and aluminum alloys, and the resulting color film has the characteristics of wear resistance and corrosion resistance, and the color range is wide. However, it is generally not used as a protective layer alone, and it is often used as a background color on parts whose surface needs to be painted.
B.Electrolytic coloring of aluminium alloy street lamp pole
The color film obtained by the electrolytic coloring process of aluminum and aluminum alloy has good wear resistance, light resistance, heat resistance, and chemical corrosion resistance. It is widely used in the decoration and anti-corrosion of aluminum profiles for modern buildings. With the utilization and development of solar energy and the diversification of daily commodities, the electrolytic coloring process of aluminum and aluminum alloys will be more widely developed and utilized.
The electrolytic coloring process has the characteristics of color fastness and fading, and is the most widely used coloring method at present. Yellow, champagne, bronze, brown, black, etc. can be obtained by changing the coloring time.
C.Aluminum alloy street light pole spray
The surface of the aluminum alloy pole can be sprayed with colored polyester powder, which has the characteristic of bright color, anti-UV and no fading.
Note: Due to the difference in material between the aluminum alloy light pole, the bottom plate, the welding wire, etc., it is inevitable that a certain color difference will occur in the welded part after anodization. If you want to ensure the consistency of the color of the surface of the rod, it is recommended to use the surface treatment of spray or fluorocarbon spray.
A.Stainless steel light pole raw material
The whole pole is made of stainless steel and has different grades such as 201, 304 and 316. The types of stainless steel street lamps are round straight light pole and conical shaped light pole. Conical street light is rolled by stainless steel plates. The height of stainless steel poles is generally 3 to 15 meter. The shape of street light pole commonly is round tapered, with a 3.34inch diameter taper at the top with a 7.87-inch butt diameter. The design of the upper and lower enhances the stability of the pole. Stainless steel light poles have the characteristic of strong hardness, corrosion resistance, beautiful appearance and smooth.
B.Stainless steel street light pole welding way
①Weld seam welding, as an important step in the formation of street light rods, has stringent requirements for the process. After the sheet is bent and formed by the plate bending machine, it enters the welding process, and the welding process called submerged arc welding. The process steps are:
1. Grinding treatment. Before welding, the welding position should be polished to prevent rust at the weld to cause bubbles after welding.
2.Straight line welding. Straight welding (also called submerged arc welding) of the polished tube blank, because the welding is fully automatic welding, it has very strict requirements for the treatment of the pre-tube blank. After welding, the welding line should be straight, and the whole is smooth and free of bubbles.
②Another welding process is automatic argon arc welding, which perfectly integrates the interfaces and does not see the shape of the welded joint. After finished the welding, it is also required to carry out ultrasonic flaw detection. Strict requirements, no one cannot be welded.
