6m Galvanized Square Tubing Hollow Steel Pipe Q235 Q235B S275 S275jr A53 St37

Product Description:

Galvanized square tube is a hollow square cross-section steel tube with a square cross-section shape and size made from hot-rolled or cold-rolled galvanized strip steel or galvanized coil plate, which is formed by cold bending and then high-frequency welding, or galvanized square rectangular tubes made by hot-dip galvanizing the pre-made cold-formed hollow steel tubes.

Product Specification:

Galvanized Square Tubing Classification:

Galvanized square tubes are divided into hot-dip galvanized square tubes and cold-dip galvanized square tubes in terms of production technology. It is precisely because of the different processing of these two galvanized square tubes that they have many different physical and chemical properties. , in general, they have many differences in strength, toughness and mechanical properties.

1. Hot-dip Galvanized Square Tube

Hot-dip galvanized square tube: It is a square tube made by welding a steel plate or steel strip after being curled and formed. On the basis of this galvanized square tube, the square tube is placed in a hot-dip galvanized pool and undergoes a series of A kind of square tube formed after chemical reaction. The production process of hot-dip galvanized square tube is relatively simple, and the production efficiency is very high. There are many varieties and specifications. This kind of square tube requires very little equipment and funds, and is suitable for small Galvanized square pipes are produced by manufacturers, but in terms of strength, the strength of this steel pipe is far lower than that of seamless square pipes.

2. Cold Galvanized Square Tube

Cold-dip galvanized square tubes use the principle of cold galvanizing on the square tubes used to make the square tubes anti-corrosive. Different from hot-dip galvanizing, cold-dip galvanized paint mainly uses electrochemical principles for anti-corrosion, so it must be ensured Full contact between zinc powder and steel produces an electrode potential difference, so surface treatment of steel is very important.
