Description
This dataset is a market dataset, representing the consumption market of the region; the dataset includes the transport of the product from the gate to the consumer end, and the transport service is calculated according to the transport situation of this product in this region. The product represented by this dataset is an angle steel tower, which is a self-supporting steel tower with hot-rolled equal-leg angle steel as the main load-bearing member, forming a space truss structure through bolted or welded connections, with a functional unit of 1 kg, mainly composed of angle steel, steel plate and flux, welding wire, etc., made through processes such as blanking, forming, welding, assembly and anti-corrosion treatment. The key upstream raw materials of this product are angle steel, steel plate and flux, welding wire, anti-corrosion materials, etc., and downstream it is mainly applied in overhead transmission lines, communication base stations, wind power and photovoltaic supports and various supporting structures. In terms of system boundary, infrastructure such as the manufacture of production equipment and the construction of plant buildings is not included within the dataset boundary. In terms of data sources and data processing, the data inventory is formed by merging data from multiple sources, and electricity and other energy are calculated using the Chinese average energy structure.
Activity Description
The system boundary is the angle steel tower from cradle-to-gate, the starting point is the input of raw materials, and the end point is the finished angle steel tower leaving the factory. The main stages include blanking (angle steel, steel plate, etc.), forming, welding (flux, welding wire, etc.), assembly and anti-corrosion treatment (painting, galvanizing, etc.).
Process Description
Angle steel tower is a self-standing iron tower that uses hot-rolled equal-edge angle steel as the main force-bearing component and is connected by bolts or welding to form a space truss structure. It is used to support overhead transmission wires, ground wires or other equipment. It is mainly composed of angle steel, steel plates and bolts or welds, and is in the form of a tower-like steel structure. It is widely used in overhead transmission lines, communication base stations, wind power photovoltaic brackets and various support structures.

Technology comment
Angle steel tower production mainly includes blanking, forming, welding, assembly and anti-corrosion treatment. The steel is blanked according to the design dimensions of the parts, and then the angle steel and other components are made into the required shape through bending, stamping, drilling, etc., and then the components are welded and assembled, and are finally inspected and shipped from the factory after surface anti-corrosion treatment (spray painting, galvanizing, etc.).
