What is chain link fence technology

What is the difference between galvanized cold galvanized chain link fence? Galvanized hook plate is a hot-rolled plate galvanized mesh fence, a chain link galvanized cold-rolled plate, a galvanized chain link fence. In terms of materials, the composition of the two galvanized chain link fences is that, except that the galvanized cold plate is thinner than the galvanized plate, the surface quality is better, the method is more complicated, and the price is basically similar. Treat it thoroughly. For steel designers, the design should also avoid pickling or cleaning with an incomplete acid pickling relative to the bonding surface to avoid gap members on the bonding surface. The yellow surface flowing phenomenon caused by the water galvanized hook. Hot-dip galvanizing is performed at an elevated temperature.

For tubular members, both ends should be open. If both ends are closed, the air in the pipe expands and the roof bursts, causing a safety accident. If one end is closed, the zinc liquid will not flow smoothly and will easily accumulate in the tube. From the technological point of view, the steel is sent from the cast billet to the hot rolling, and then rolled into a certain thickness of steel plate, such as the thickness of about 10 mm. If the user does not have higher requirements for the surface, thickness and mechanical strength of the plate, then the finished product can be processed, such as the direct sale of galvanized iron wire, that is, hot plate. If there are higher requirements for the plate, the hot-rolled plate can be sent to the cold-rolled production line for further processing. After pickling, annealing, and re-rolling, the cold-rolled plate can be thinner, smoother, and more mechanical. Good plank. Which traditional crochet technique has been rapidly developed?
