Galvanized steel is mild steel with a coating of zinc. The zinc protects the steel by providing cathodic protection to the exposed steel, so should the surface be damaged the zinc will corrode in preference to the steel.

Galvanized roof shingles are made of galvanized steel sheet used for roofing and coated with zinc. The zinc coating provides moisture and oxygen protection for the base steel. According to the galvanizing process, it can be divided into hot-dip galvanized steel plate

DX53D galvanized sheet has low carbon content, good stamping ductility, and is suitable for general deep drawing processing.

SGCC galvanized sheets are mainly used in construction, transportation, light industry, agriculture, marine and other fields, such as building exterior walls, roofs, highway guardrails, refrigerators, air conditioners, etc.

Galvanized square steel pipe is a kind of hollow square section steel pipe with square section shape and size made of hot rolled or cold-rolled galvanized strip or galvanized coil after cold bending and forming, and then high-frequency welding, or galvanized square steel pipe made in advance by hot dip galvanizing.

Hot-dip galvanized steel pipes are widely used in the manufacturing industries of construction, machinery, coal mining, chemical industry, electric power, railway vehicles, automobile industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery, shed construction, etc.

Characteristics of galvanized seamless pipe Light weight, easy to handle Because the galvanized seamless pipe itself is relatively light, the daily transportation and construction are very simple, which can save a lot of time and cost. Good corrosion resistance The corrosion resistance of seamless steel pipes is very good. They are resistant to acid, alkali, salt and atmospheric environment.

Hot dip galvanized pipe is to make molten metal react with iron substrate to produce alloy layer, so that the substrate and coating can be combined. Hot galvanizing refers to pickling the steel pipe first. In order to remove iron oxide on the steel pipe surface, after pickling, the steel pipe is cleaned in ammonium chloride or zinc chloride aqueous solution or mixed ammonium chloride and zinc chloride aqueous solution tank, and then sent to the hot dip tank. Hot dip galvanizing has the advantages of even coating, strong adhesion and long service life.

Spiral welded pipe: strips of low carbon steel or low alloy structural steel are rolled into billets according to certain spiral angles (called forming angles) and then welded together to make pipes. Can produce large diameter narrow band steel pipe.

Carbon steel rectangular tube is a type of steel pipe with a square cross-section, mainly composed of elements such as carbon, manganese, silicon, phosphorus, sulfur, etc.
