Description
The product represented by this dataset is an angle-steel tower, namely a self-supporting steel tower with hot-rolled equal-leg angle steel as the main load-bearing members, forming a spatial truss structure through bolted or welded connections, with a functional unit of 1 kg, mainly composed of angle steel, steel plates and flux, welding wire, etc., manufactured through processes such as cutting, forming, welding, assembly and anti-corrosion treatment. The key upstream raw materials of this product are angle steel, steel plates and flux, welding wire, anti-corrosion materials, etc., and the downstream is mainly applied to overhead transmission lines, communication base stations, wind power and photovoltaic supports and various support structures. As for the system boundary, infrastructure such as the manufacture of production equipment and plant construction 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 energy such as electricity is calculated using China's average energy mix.
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.).
