Hot-dip galvanized square pipe is processed and formed after the square pipe is processed, and then put into the hot-dip galvanizing pool for chemical reaction, so that it forms a layer of galvanized layer on the surface to achieve the effect of anti-corrosion and anti-rust. How to judge the quality of hot-dip galvanized square pipe? Let's find out together!The treatment of hot-dip galvanized square pipe is relatively simple, but the performance after the forming of the tube has been greatly improved, regardless of strength or toughness will be much better than ordinary square pipe, and the resistance to oxidation environment in engineering construction erosion has a wide range of applications.

In terms of its quality, it is easy to see from the appearance. First of all, if the galvanized layer on the surface of the hot-dip galvanized square pipe is uneven and has a large range, it can be judged as an unqualified product.Observe the surface of the galvanized pipe to see if there is a leaky coating, and white spots. These characteristics do not mean that the material of the hot-dip galvanized square pipe is not good or the processing is not standard when galvanizing, but that such a combination indicates that the quality of this galvanized square pipe is not good enough.

If you see that the galvanized layer of the hot-dip galvanized square pipe has bubbles and the color contains a slight green color, this can also indicate that the quality of the galvanized layer is unqualified.Galvanized square pipe has good strength, toughness, plasticity and welding properties, and good ductility. Its alloy layer is firmly attached to the steel base, so the galvanized square pipe can be cold-stamped, rolled, wire-drawn, bent and formed without damaging the coating; It is suitable for drilling, cutting, welding, cold bending and other general processing processes. The surface of the galvanized parts is bright and beautiful, and can be directly used in engineering as needed.
