1. Different references
1. cold binding plate: hot rolled coil as raw material, at room temperature under the recrystallization temperature to stop rolling products.
2. galvanized plate: refers to the appearance of a layer of zinc plated steel plate.
Second. different characteristics
1. cold binding plate: because it does not stop heating, there is no pitting and oxide sheet defects that are often presented in hot rolling, and the appearance is good and the brightness is high. Moreover, the dimensional accuracy of cold-rolled products is high, and the performance and organization of products can meet some special application requirements, such as electromagnetic properties and deep drawing properties.
2. galvanized sheet: Galvanized sheet due to the different treatment methods in the plating process, the appearance of the state is different, such as ordinary zinc flowers, fine zinc flowers, flat zinc flowers, zinc flowers and phosphating treatment appearance. The German code also rules for appearance levels.
Three. different uses
1. cold tie plate: mostly used in automobile manufacturing, electrical products and so on.
2. Galvanized sheet: mainly used in construction, light industry, automobile, agriculture, animal husbandry, fishery and commercial industries. The construction industry is mainly used for the manufacture of anti-corrosion industrial and civil building roof panels, roof grilles, etc. The light industry uses it to manufacture home appliance housings, civil chimneys, kitchen utensils and so on.
Zinc-steel balcony guardrail has the following characteristics:
1. welding free assembly design, quick and simple installation.
2. four layers of anti-corrosion treatment, more than 20 years of service life, to solve the traditional products in a short time of rust, powder, cracking and other problems, eliminating product maintenance and update costs.
3. good decorative, rich color, to meet the individual needs of different customers.
4. environmental protection, does not pollute the environment, to solve the problem of ordinary products polluting buildings.
5. good flexibility, the rigidity and flexibility of the substrate make the guardrail products have better impact resistance.
6. electrostatic spraying of the surface of the imitation pond porcelain process, so that the guardrail products have good self-cleaning performance, rain wash and water gun spray can be clean as new.
7. buried installation mode and foot plate installation, that is, save your building foundation costs, but also save land resources.
8. good weather resistance, salt spray resistance and moisture and heat resistance, suitable for use in different regions. Steel stamping accessories, stamping guardrail accessories 32t connector 35t connector 40t connector 45t connector U-card 30*40LN bracket 35LN bracket 40 several brackets ð
Zinc-iron alloy plate is also called alloyed galvanized plate. The alloying process heats the galvanized strip through the alloying furnace to 550~560 ° C in 5~10 seconds in order to convert the pure zinc layer into an iron-zinc alloy. Its weldability, coating performance, heat resistance, corrosion resistance are better than ordinary galvanized sheet.
Performance and characteristics
1. Suitable for alkaline low iron zinc iron alloy process, coating iron content 0.3 ~ 0.8%;
2. Fine crystal coating, brightness is white;
3. The alloy coating is easy to passivation, and the corrosion resistance of the alloy coating after passivation is more than three times that of the zinc layer passivation;
4. Stable plating solution, easy to maintain, can be hung plating or roll plating (including automatic line);
5. The cost is relatively low, and the original equipment can be used to turn the original zincate galvanizing liquid into a trough.
Use
By alloying, it can be made into superalloy or super alloy, corrosion resistant alloy, high resistance alloy, electric vacuum alloy and other materials with special properties. Widely used in aerospace, aviation, shipbuilding, electronics, electrical, machinery, chemical, electroplating and other industrial sectors.
In the early days, there were more zinc-iron alloys in automobiles, such as gasoline pumps, carburetors, and so on.
Because the surface galvanized liquid contains iron, so the welding performance is better than ordinary galvanized, also has rust resistance and corrosion resistance, the application is very wide.
