Description
The product represented by this dataset is a frame-mounted lightning rod, namely a lightning protection device installed on the frame of a building or structure (such as roofs, walls, etc.), with a single-piece weight of about 4.19 kg, mainly composed of steel (steel pipes, round steel, etc.), zinc and components (electronic components, plastics, rubber, etc.), manufactured through processes such as straightening, electric heating, thermal zinc spraying, cooling, cutting and assembly. The key upstream raw materials of this product are steel, zinc and components such as electronic components, plastics and rubber, and the downstream is mainly applied to the lightning protection of civil buildings, plants, schools, warehouses and important buildings, etc. As for the system boundary, the packaging of the product and its post-delivery transport, use, scrapping, recycling and final disposal, as well as infrastructure such as the manufacture of production equipment and plant construction, are 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.
Activity Description
The system boundary is from the cradle-to-gate of the frame-type lightning rod. The starting point is the input of raw materials and the end point is the finished product leaving the factory. The main stages include, in order, straightening (steel), electric heating, thermal spraying (zinc), cooling, cutting and assembly.
Process Description
Lightning rods are devices used to protect buildings, tall trees, and other structures from lightning strikes. They are mainly divided into independent lightning rods and frame-type lightning rods. Frame-type lightning rods are usually installed on the frames of buildings or structures, such as roofs and walls. The rod is typically made of steel pipes, round steel, and other materials, and is fixed to the frame by welding or bolting. It is mainly composed of steel (steel pipes, round steel, etc.), a thermally sprayed zinc coating, and components (electronic components, plastics, rubber, etc.). It takes the form of a rod-shaped or tower-shaped device and is widely used for lightning protection in general civil buildings, factories, schools, warehouses, and important buildings.

Technology comment
The production of frame-type lightning rods mainly includes processes such as straightening, electric heating, hot spray zinc, cooling, cutting and assembly. After the steel is straightened by a straightening machine, it is heated by a heating machine and hot-sprayed with zinc. After cooling, it is cut and then assembled with parts (electronic components, plastics, rubber, etc.) to obtain the finished frame-type lightning rod.
