Basic knowledge of high mast pole
The high pole lamp generally refers to a new type of lighting device composed of a steel column type pole and a high power combined lamp holder of 15 meters or more. It consists of a lamp cap, a
How to control steel structure welding deformation
In the construction of steel structure engineering, the welding deformation directly affects the installation and use functions of steel components and steel structures. And the additional bending mom
Flange welding
The main design flaw of flat-welded flanges is that it does not guarantee zero leakage. This is its design deficiencies: the connection is dynamic, and periodic loads such as thermal expansion and und
hot-dip galvanized and cold galvanized
The galvanizing pole divided into hot-dip galvanizing and cold galvanizing. The hot-dip galvanizing melts the zinc, and then the pole passes through the zinc liquid to form a galvanized layer on the s
China Steel Price Trend and in Market supply
Affected by factors such as rapid release of production capacity in January and February and high steel inventories, steel prices fell significantly in March, but such momentum is expected to be rever
gas shield welding advantages
Compared with other welding methods, gas shielded welding has the following characteristics: (1) The visibility of the arc and the molten pool is good, and the welding para
High Mast Lighting Pole introduction
The pole part 1 and the pole height are 15-45 meters, the lamp panel is a frame structure; the bottom flange is circular.
High pole light detailed technical descrip
the Belt and Road Initiative
With the strong promotion of the national initiative, the Shangchai power engine has maintained rapid growth in overseas markets. Under the continuous promotion of the national “Bel
Street Lighting Poles
Protection measures for street light poles On the installed street lights, the solar street light poles are completely exposed to the outside. Therefore, in order to preven
Solar light pole specification
1. The main solar energy garden light pole adopts one-time forming technology. The steel rod weld seam is required to be smooth and smooth. The flat part of the whole light rod body weld protrus
The Galvanizing of cold and hot difference
The galvanized chain link network is divided into a hot-dip galvanized chain link network and a cold galvanized chain link network. The difference between the two is: hot-dip galvanizing is the immers
Road Lighting Pole With Production Type
1. The light pole is mainly divided into two categories: conical and polygonal pyramidal.
For a conical light pole, the roundness error of the section should not exceed 5 ‰.
