Classification and code of surface structure
| Classified items | category | Code | |
| Coating type | Pure zinc coating | Z | |
| Zinc iron alloy | ZF | ||
| Plating forma,b | Equal thickness coating A(g/m2)/B(g/m2) (A=B) | A/B | |
| Differential thickness coating A(g/m2)/B(g/m2) (A≠B) | |||
| a: A is the weight of the outer surface coating of the steel strip or the upper surface coating of the steel plate (g / m2); B is the weight of the inner surface coating of the steel strip or the lower surface coating of the steel plate (g / m2). | |||
| b: After negotiation between the supplier and the buyer, the code of equal thickness coating can be expressed by the sum of the weight of both sides. | |||
Classification and code of surface structure
| Surface structure | code | Feature | application |
| Regular spangle, | Z | Zinc flower obtained by condensation of zinc layer under normal conditions after galvanizing. | General purpose |
| minimal spangle , | X | The surface formed by controlling the condensation of the zinc layer presents small zinc flowers smaller than normal zinc flowers | It is used for the purpose where the normal zinc flower cannot meet the surface appearance requirements. |
| Finishing spangle | G | Surface structure obtained by special finishing treatment. | It is used for applications with high surface quality requirements, such as color coated substrate. |
| Finishing minimal spangle | GX | ||
| zero spangle, | N | The specific production process is adopted to make the surface of the coating free of zinc flowers visible to the naked eye. | |
| Zinc iron alloy | R | No zinc flower, gray, generally dull. | Suitable for further painting. |
Classification and code of surface treatment
| surface treatment | code | features |
| Chromate passivation | L | Chemical treatment to prevent white rust during transportation and storage |
| Oiling | Y | In order to prevent white rust during transportation and storage. |
| Chromate passivation + oiling | LY | In order to further avoid white rust, the product surface shall be further oiled after chromic acid passivation |
What are advantages of galvanized steel?
Because it is produced through applying Zn coat on both faces by hot dip process. It enjoys both the physical protective feature and the electrochemical protective property of Zn.
>>Machinability: It can satisfy the processing requirements of rolling, coiling and others processes alike.
>>Thermal resistance: Common HDG steel plate normally works under 230℃, and has its color changed at 250℃, however, Galvanized steel plate can sustain the environment at 315℃ for long time.
>>High reflectivity: Reflection ability of heat and light is twice as much as those of hot-dip zinc steel sheet, and its reflectivity is more than 0.70, which is an ideal construction materials of saving energy.
