1. The difference in meaning
Galvanized iron is a thin plate of low-carbon steel that is galvanized on the surface. Its basic thickness is generally about 0.44 to 1.2 mm, and the thickness of the zinc layer is more than 0.02 mm. Galvanized iron sheet can be divided into two types: flat plate and corrugated (waveform). The ungalvanized sheet is commonly known as black iron sheet. Galvanized steel plate is a kind of welded steel plate with hot dip plating or electrogalvanized layer on the surface. Galvanized steel plate can be divided into ordinary electrolytic plate and fingerprint resistant electrolytic plate. The fingerprint-resistant board is mainly based on an ordinary electrolytic board to increase the fingerprint-resistant treatment, which can resist sweat, and is generally used on parts that do not undergo any treatment. Ordinary electrolytic plates are divided into phosphating plates and passivating plates.
2. The difference in characteristics
The galvanized iron sheet is basically not easy to rust and has strong corrosion resistance, and its ductility is also relatively strong. Galvanized steel sheet can effectively prevent steel corrosion, prolong service life, excellent paintability, decoration and good formability, heat conduction and heat reflectivity.
3. The difference in use
Galvanized iron sheet is a widely used iron coiled material in industry and manufacturing. It is often used to manufacture roofing, coiled pipes and various containers. Galvanized steel sheets are widely used in construction, vehicles, home appliances, daily necessities, light industry, agriculture, transportation and other industries as the main purpose.
