1. Pay attention to the storage environment. After purchasing galvanized sheet, the user needs to choose the right environment for storage. Generally speaking, galvanized sheet needs to be stored in a better ventilated place in the house, and attention should be paid to prevent water leakage and moisture penetration. Especially if the wrapping paper of galvanized sheet has been damaged, corresponding measures need to be taken, so before storage, we need to check whether the packaging of galvanized sheet is damaged.
2. Pay attention to the storage location and corresponding details galvanized sheet in storage to shorten the storage time as far as possible, because a long time of storage may be vulnerable to environmental pollution and surface corrosion, it may also be in the case of galvanized sheet is subjected to abnormal pressure, the surface of the new layer caused by part off. In the storage of galvanized plate should be under the cushion wood or support frame, and stacked layers, as low as possible, should not be more than two layers. In addition, attention needs to be paid to prevent oil powder or dirt from sticking to the surface of galvanized sheet, thus affecting the effect of galvanized.
3. Pay attention to rain prevention when storing galvanized plate, we should pay attention to choosing a good ventilation environment, but do not choose the open environment. If we have to choose the open environment, we need to pay attention to rain prevention measures, cover the rain cloth, use rubber cushion or wood cushion.
4. Galvanized steel plate is divided into ordinary electrolytic plate and fingerprint resistant electrolytic plate. Fingerprint resistant plate is added on the basis of the ordinary electrolytic plate with a fingerprint resistant processing, sweat resistant, generally used in the parts without any processing, brand SECC-N. Ordinary electrolytic plate and phosphating plate and passivation board, phosphating is more commonly used, brand SECC-P, commonly known as p material. Passivated plates can be oiled or unoiled.
For example:
Hot dip zinc steel plate (SGCC) has one advantage over electric galvanized steel plate (SECC), SECC bending and section is very easy to rust, SGCC is much better! Quality cases are usually made of SECC or SGCC galvanized steel plates. The steel plates made of this material are shiny in color and have a metallic sheen. The advantage of this steel plate is that it has good corrosion resistance.
Electric galvanized steel (SECC): uniform gray, mainly imported, fingerprint resistance, has very superior corrosion resistance, and maintains the workability of cold rolled sheet. Uses: Household appliances, computer cases and some door panels and panels can be produced by Shanghai Baosteel, but the quality of zinc layer is much worse than that of foreign countries.
Hot dip zinc steel plate (SGCC): dipping, bright white, small zinc flower, in fact, it is difficult to see the zinc flower, large zinc flower can obviously see the kind of hexagonal flower block, there is no steel can produce high-quality materials, mainly imported from abroad, Taiwan has chinasteel, Two shengyu steel corporation can produce. Main characteristics: corrosion resistance; Lacquerability; Formability; Spot weldability. Use: very wide, small household appliances, good appearance, but compared with the SECC, its price is more expensive, many manufacturers use the SECC to save costs.
Divided by zinc, zinc flower size and zinc layer thickness can explain the quality of zinc plating, the smaller the thicker the better. Of course, don’t forget to make manufacturers resistant to fingerprint processing. There is also the possibility to distinguish by its coating: such as Z12 said the total amount of double-sided coating 120g/mm.
