Galvanized coil is a thin steel plate with Q235 as the base material immersed in melted zinc tank, so that its surface adhesion of a layer of zinc thin steel plate. The width is generally 800-1250mm, and the surface treatment is divided into 5 kinds. Galvanized coil products are mainly used in construction, light industry, automobile, agriculture, animal husbandry, fishery and commercial industries.

What is galvanized roll

  • Galvanized coil is a thin steel plate with Q235 as the base material immersed in melted zinc tank, so that its surface adhesion of a layer of zinc thin steel plate. The Width is generally 800-1250mm, and the surface treatment is divided into 5 kinds.The main use of continuous galvanizing process production, that is, into a roll of steel plate continuous dip in the melting of zinc plating tank made of galvanized steel plate; Harvest a steel coil by rolling machine.

  • Galvanized coil products are mainly used in construction, light industry, automobile, agriculture, animal husbandry, fishery and commercial industries. The construction industry is mainly used for manufacturing anti-corrosion industrial and civil building roof panels, roof grilles, etc. The light industry uses it to manufacture home appliance shells, civil chimneys, kitchen utensils, etc., and the automobile industry mainly uses it to manufacture corrosion-resistant parts of cars, etc. Agriculture, animal husbandry and fishery are mainly used as food storage and transportation, frozen processing tools for meat and aquatic products, etc. Commercial mainly used as materials storage and transportation, packaging appliances.

Classification and code specification for zinc layer surface structureDue to strain test marketing, the polished steel plate and strip of grade 01~04 are leveled by an effective straightening machine before processing to avoid the occurrence of slip lines. Grade 05 or 06 polished steel plates and strips are unaged and can avoid slip lines for 6 months.

Galvanized coil surface treatment

 passivation

The zinc coating can be passivated to reduce the rust (white rust) in the condition of wet storage and transportation. However, the corrosion resistance of this chemical treatment is limited and, moreover, hinders the adhesion of most coatings. This treatment is generally not in the zinc iron alloy coating, in addition to the finishing surface, as a general, the production plant on other types of galvanized layer are passivation treatment.

oil

Oiling can reduce the corrosion of steel plate under wet storage condition, and oiling the passivated steel plate and strip will further reduce the corrosion under wet storage condition. The oil layer should be able to be removed with a degreaser that does not damage the zinc layer.

paint sealant

An additional corrosion protection, especially fingerprint resistance, is provided by applying an extremely thin transparent organic coating film. Lubricity can be improved when forming, and as the adhesion bottom of the subsequent coating.

phosphating

Through phosphating treatment, the galvanized steel plate of various coating types can be coated without further treatment in addition to normal cleaning. This treatment can improve the adhesion and corrosion resistance of the coating and reduce the risk of corrosion during storage and transportation. After phosphating, it can be used with suitable lubricant to improve the molding performance.

 does not handle

Plates and strips supplied in accordance with this standard may not be passivated or oiled or coated or coated or phosphating only if the orderer so requests and is responsible for such non-treatment.
