I believe many people have seen square pipes. During the anti-corrosion construction process of oil (gas) pipelines, the surface treatment of square pipes is one of the key factors that determine the length of the anti-corrosion service life of the pipeline.

Double-sided galvanized thickness 20μ weight 150g/m2 plus steel plate self-weight (0.5mm thick) is: 0.15+85x0.50.15+925075kg/m2

Square tube is a hollow square cross-section lightweight thin-walled steel tube, also known as steel cold-bent profile.

Galvanized steel plate is divided into ordinary electrolytic plate and anti-fingerprint electrolytic plate.

Generally, when welding hot-dip galvanized square pipes, it is necessary to check whether the water, electricity, and gas are connected, and all connections must be made as required without loosening.

There are several aspects to consider when selecting suitable pre-coated steel coils for construction.

On the continuous unit, cold-rolled strip steel and galvanized strip steel (electro-galvanized and hot-dip galvanized) are used as the substrate. After surface pretreatment (degreasing and chemical treatment), one or more layers of liquid are applied by roller coating. Coating, the plate obtained after baking and cooling is the coated steel plate.

Flowered galvanized sheet (also called tinplate) is formed by condensation after normal galvanizing. It is divided into: large flower galvanized sheet and small flower galvanized sheet, which is suitable for the engineering industry.

Galvalume plate is an alloy material composed of aluminum and zinc, which is made through a series of processing techniques. It is lightweight, corrosion-resistant, and wear-resistant, and is used in construction, home decoration, automobile manufacturing, and other fields.
