Tianjin Tianyingtai Steel Pipe Co., Ltd. is one of the most credible manufacturers and suppliers of zinc plated sheet steel in China. Welcome to consult the quotation and import cheap zinc plated sheet steel made in China here from our factory.

CLASSIFICATION

The galvanized steel sheet is divided into ORDINARY ELECTROLYTIC PLATE and FINGERPRINT RESISTANT ELECTROLYTIC PLATE.

THE FINGERPRINT RESISTANT BOARD adds a fingerprint processing on the basis of ordinary electrolytic plate, and it can resist sweat. It is commonly used in parts that with no treatment, and the steel grade is SECC-N.

THE ORDINARY ELECTROLYTIC PLATE also divides into the phosphating plate and the passivating plate. The phosphating is commonly used, and the steel grade is SECC-P, commonly known as the P material. The passivation plate is divided into oil and non oil.

For example：

Hot dip galvanized steel plate (SGCC) with galvanized steel sheet (SECC) has advantages, SECC bending section and rust easily, SGCC is much better! Quality chassis usually adopts SECC or SGCC galvanized steel sheet, using the same chassis plate color shiny, metallic luster, advantages of this steel plate is good corrosion resistance.

Galvanized steel sheet (SECC): uniform gray, main import, fingerprint resistance, excellent corrosion resistance, and maintain the processing property of the cold rolled plate. Uses: electrical appliances, computer shells and some door panels and panels, Shanghai Baoshan steel can be produced, but the quality of zinc layer is much more foreign.

Hot dip galvanized steel plate (SGCC): dip, bright white, small zinc flowers, in fact it is difficult to see the zinc flowers, big zincflower obviously can see that hexagonal flower piece, there is no domestic steel mills can produce high-quality materials, mainly imported from abroad, Taiwan chinasteel, Shengyu steel corporation can produce two. Main characteristics: corrosion resistance; varnished property; formability; spot weldability. Uses: very wide, small household appliances, good appearance, but compared to SECC, its price is more expensive, many manufacturers to save cost to SECC.

According to the zine division, the size of zinc flower and the thickness of zinc layer can explain the quality of zinc plating, the smaller the thicker the better. Of course, don't forget to let factory Gane fingerprint. And it may be distinguished by its coating, such as Z12, which represents the total amount of 120g/mm. For example:

Aluminized zinc plate (SGLD): it is a multiphase alloy containing aluminum rich and zinc rich. Because of the characteristics of aluminum and zinc, it has a better performance than the hot dipped zinc plate (SGCC). Main features: corrosion resistance, the ability is much higher than SGCC; heat resistance; heat conduction and heat reflection; molding; welding. Usage: in some reflective good place, such as the reflection plate inside the oven, rice cooker reflector. The Shengyu Steel Corporation in Taiwan can be produced. There is no steel factory that can be produced in China. The price is much more expensive than SGCC. Hot dip galvanized steel plate (SGCC) is generally used, aluminium zinc plate (SGLD) is a deep drawing, SGCE is super deep drawing.

SURFAVE

(1) surface state: The surface state of galvanized coating sheet is different due to the different process treatment, such as regular spangle, fine spangle, smooth spangle, no zinc flower and phosphating surface etc.. The German standard even stipulates a surface grade.

(2) galvanized steel sheet should have good appearance, no harmful defects for products. Such as no plating, holes, breakage and scum, over plating thickness, scratch, chromic acid dirt, white rust and so on.

Foreign standards are not very clear on specific appearance defects. Some specific defects should be listed in the contract at the time of order.
