application of Galvanized Steel Strip dx51d
Construction
Construction is one of the main application areas for DX51D G.I. strips coil. Due to its excellent corrosion resistance and moulding properties, it is widely used in the fabrication of building components such as roofs, walls and floor slabs. In addition, galvanized steel strip can also be used to make ventilation ducts, water tanks and other metal products.
Transportation
The transportation field is one of the important application areas of DX51D galvanized strip. Due to its excellent corrosion resistance and molding performance, it is widely used in the manufacture of automobile shells, carriages, doors and other automobile parts. In addition, it can also be used to manufacture lightweight metal products such as bicycle frames and motorcycle frames.
Electronics
Due to its good surface quality and easy processing and moulding, it is widely used in the manufacture of metal housings for electronic components, circuit boards, and so on. In addition, it can also be used to manufacture precision metal products such as battery housings and connectors.
In addition to the above fields, DX51D galvanized steel strip can also be used in the fields of petroleum, chemical industry, food and so on. For example, in the petroleum field, it can be used to manufacture fuel tanks, pipelines, etc.; in the chemical field, it can be used to manufacture storage tanks, reactors, etc.; in the food field, it can be used to manufacture storage cabinets, refrigerators, etc.
General galvanized steel strip processing process:
(1) pickling (to remove iron oxide on the surface of the strip)
2) cold rolling (rolling thin, improving wall thickness tolerance, surface finish)
3) galvanized (in the iron substrate to form a zinc-iron alloy layer + zinc layer, anti-corrosion, beautiful)
4) Delivery (part of the product after slitting and slitting, to the net edge state delivery)
Special Note: Some of the thicker galvanized steel strips (such as the thickness of 2.5mm or more), do not need cold rolling, or pickling directly after galvanizing, called pickling straight plating, this mainly depends on the downstream product requirements.
Galvanized steel strip is a commonly used metal material with excellent corrosion resistance and good forming properties, so it is widely used in construction, transportation, electronics, etc. DX51D is a specification of galvanized steel strip. "D" denotes galvanized sheet."X" indicates that the substrate is hot rolled."51″ serial number, no specific meaning, represents the general use .
