Steel Light Pole Equipment

In china, there are different types poles used for public street lighting, Like cement pole, steel light pole, Aluminium light pole or FRP light pole.

1.Wood light poles

usa wood light poles        In history, limited by pole making technology, most countries lighting pole were made from wood. now it was history in most countries. of course, we still can see such poles in some Forest-based countries.

2. Cement Light Pole

cement lighting pole       Cement poles were used a long time in china. It was our childhood memory. Because of its heavy weight, large transportation cost, and relatively dangerous, the market has gradually phased out this kind of street light pole.

3. Steel Light Poles

steel lighting poles made in china   Iron street light pole, also known as high-quality Q235 steel light pole. It is made of high-quality Q235 steel, hot-dip galvanized and spray-coated. It can be rust-free for 30 years and is very hard. This is the most common and used street lamp pole in the street lamp market.

4. FRP (Fiber Reinforced Polymer) Lighting Pole

frp light poles   Glass fiber reinforced plastic light pole is an inorganic non-metallic material with excellent performance. There are many types. The advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength. Therefore, not many are used in the market.

5. Aluminium Alloy Lighting pole

aluminium lighting poleAluminum alloy street light poles are made of high-strength aluminum alloy. The manufacturer not only protects human safety, but also has high strength, does not require any surface treatment, has more than 50 years of corrosion resistance, and is very beautiful. Looks more upscale. Aluminum alloy has better physical and mechanical properties than pure aluminum: easy processing, high durability, wide application range, good decorative effect, rich colors and so on. Most of this street light poles are exported overseas, especially in developed countries.

6. Stainless Steel Light Poles

stainless steel light polesStainless steel light poles have the good chemical and electrochemical resistance in steel, second only to titanium alloys. The method adopted by our country is to perform hot-dip galvanizing surface treatment. The product life of hot-dip galvanizing products that meet international standards can reach 15 years. Otherwise it is far from reaching. Mostly used in courtyards, communities, parks and other places. Heat resistance, high temperature resistance, low temperature resistance and even ultra low temperature resistance.

High Mast Pole Machine

The High mast light pole is made of high-quality Q235 steel, through the steel molding made into Plug-in taper pole. The whole surface is hot-dip galvanized and sprayed, and the pole is divided into three sections.

High mast pole is composed of lamp holder, internal lamp electrical, pole body and basic parts. The shape of the lamp holder can be determined according to user requirements.

The internal lamps are mostly composed of floodlights and floodlights. The light source uses NG400 high-pressure sodium lamps with a lighting radius of 60 meters. The rod body is generally a pyramid-shaped single body structure, which is rolled out of steel plate, with a height of 15-40 meters, and most of it is composed of two to three sections.Equipped with automatic lifting system, stable lifing, easy maintenance.

Our tewei high mast pole machine can make poles as your requirement.

Electric Pole Machine Manufacturing progress:

Raw Material :When purchasing the raw material (steel plate), on sheet of mill certificate from mill factory must be enclosed. When the raw material arrives at the warehouse, the quality department must take the elongation test and the chemical composition analysis to make sure the raw material have meet all the standard that the needed before production.

Plasma Cutting:Cuting the raw material that have meet all the standard required into different length and width. CNC laser cutting is used to direct the material or the laser beam generated. A typical commercial laser for cutting materials would involve a motion control system to follow a CNC or G-code of the pattern to be cut onto the material. The focused laser beam is directed at the material, which then either melts, burns, vaporizes away, or is blown away by a jet of gas, leaving an edge with a high-quality surface finish.

Bending:Forming the cutted steel plate into the shape (circular or polygonal or other shape ) that as per specified in the drawing. This invention relates to forming devices and more particularly to devices or machines for bending longitudinally rolled sections or strips of metal stock to desired curvilinear shapes.

Welding:After molding, weld the steel plate together. Usually it is longitudinal welds. It adopts A.C.inverter control, with functions of stable running and fast traveling speed; The seam-tracking arc-guide mechanism is three-spindle system to guarantee the alignment without aberrancy; The main frame and welding machine are intergrated control, with flux auto-recovering system and it is easy to operate with high efficiency.
