Shanghai AIYIA Industrial Co., Ltd. produces high-quality hot-dip galvanized steel coil and electro-galvanized. Low price and excellent quality, it is a good building and decoration material. Our galvanized products are exported all over the world, which promotes the development of the local economy. You are welcome to purchase! What Is Galvanized Steel?
The galvanized coil is a thin steel plate in which a thin steel plate is immersed in a molten zinc bath to adhere a layer of zinc to the surface.Galvanized steel is a surface treatment technique that coats a layer of zinc on the surface of a metal, alloy or other material for aesthetics, rust prevention, and the like. The main method used is hot-dip galvanizing. Zinc is easily soluble in acid and soluble in alkali, so it is called an amphoteric metal. Zinc hardly changes in dry air. In moist air, a dense zinc carbonate film is formed on the zinc surface. In the atmosphere containing sulfur dioxide, hydrogen sulfide and marine, the corrosion resistance of zinc is poor, especially in the atmosphere containing high temperature and high humidity containing organic acid, the zinc coating is easily corroded.
The standard electrode potential of zinc is -0.76V. For steel substrates, zinc coating is an anodic coating. It is mainly used to prevent corrosion of steel. Its protective performance has a great relationship with the thickness of the coating. After passivation, dyeing or coating of the photoresist, the zinc coating can significantly improve its protection and decorative properties.

Hot dip galvanizing (HDG):it is one of the common galvanizing methods. The process is to completely dip iron or steel into molten zinc.
Electro-galvanizing(EG):it is to remove the oil, pickle, and then put into the solution of zinc salt by electrolysis equipment, and connect the negative electrode of the electrolysis equipment, place the zinc plate on the opposite side of the pipe fitting, and connect When the positive electrode of the electrolysis device is turned on, a layer of zinc is deposited on the pipe by the directional movement of the current from the positive electrode to the negative electrode, and the cold-plated pipe member is processed and then galvanized. Production Process
The production process of hot-dip galvanized sheet:preparation of original board → pre-plating treatment → hot dip plating → post-plating treatment → finished product inspection. According to the habits, the hot-dip galvanizing process is divided into two categories: off-line annealing and in-line annealing. Main Features
1.Anticorrosive:13 years in heavy industrial areas,50 years in the ocean,104 years in the suburbs and 30 years in cities.
2.Cheap:The cost of hot-dip galvanizing is lower than that of other coatings.
3.Reliable:The zinc coating is metallurgically bonded to the steel and forms part of the steel surface,so the coating is more durable.
4.Strong toughness:The galvanized layer forms a special metallurgical structure that can withstand mechanical damage during transportation and use.
5.Comprehensive protection:Every part of the plated piece can be galvanized,and is fully protected even in depressions,sharp corners,and hidden places.
6.Save time and energy:Galvanizing process is faster than other coating methods.Product Display Production Line Product Packaging
The steel strips supplied according to the standard are usually applied with common rustproof oil film, which can be swept away with alkali solution. The supplier guarantees that the oiled products will be free from rust under normal packing, transportation, loading and storage conditions within 6 Months, the approved delivery date. However, product without oil coating can also be subject subject to statement in the contract reached after discussion between the user and the supplier.
Product Transportation
We offer different modes of transport depending on the customer's destination: rail transport and ship transport.The Shipping Mark shall consist of: Trade mark, Seller's name, Product name, Applicable standards, Specifications, Package No., Contract No., Heat No., Weight of zinc film, Color, Production date, Weighing method, Net weight, Gross Weight, Consignee and Protection symbols, etc. Quality CertificationCustomer Friends From All Over The World Guide For Ordering Products
