Inspection of Hot-Dip Galvanized Steel
The inspection of hot-dip galvanized steel products includes the base metal material and mechanical properties (tensile test/bending test), thickness, width, length, zinc coating thickness, spangles (surface), packaging, profiles, etc.
Hot Dipped Galvanized Steel Prices
Galvanized steel prices last March were much higher than those in the same period this year. Besides, since the beginning of 2023. hot-dipped galvanized steel prices have shown an upward trend. In March, our HDG coil FOB price ranges from USD 680 to 1.100. It is greatly influenced by zinc coating thickness, thickness, width, order quantity, etc. The galvanized sheet and strip prices will be higher than that of coils (for the same specifications).
Hot Dip Galvanized Steel Properties
1. Excellent Resistance to Corrosion
The zinc coating forms a barrier that protects the underlying steel from corrosion caused by exposure to moisture, chemicals, and oxygen. It also acts as a sacrificial anode, corroding before the steel, thereby increasing its resistance to corrosion. The thicker the zinc coating, the better the corrosion resistance.
2. Longevity
Hot-dip galvanized steel has a long lifespan due to its high resistance to corrosion, making it suitable for outdoor applications where it is exposed to harsh environmental conditions.
3. Low Maintenance
Galvanized steel requires less maintenance than other types of steel because the zinc coating protects it from rusting and corroding. This leads to lower maintenance costs over time.
4. Toughness
Galvanized steel keeps the properties of steel. It is a durable material that can withstand harsh conditions, including impact and abrasion. Its toughness makes it an ideal material for construction and industrial applications.
5. Cost-effective
Although the initial cost of galvanized steel may be higher than untreated steel, its long lifespan and reduced maintenance costs make it a cost-effective solution over time.
6. Aesthetics Appearance
HDG steel has a shiny and smooth appearance with beautiful spangles (or zero spangles) so that it can be used directly. Moreover, it can be embossed or painted to meet different applications.
Uses of HDG Steel
HDG steel is mainly used in construction, home appliances, automobile manufacturing, containers, transportation, and other industries.
In the construction industry, it is widely used as roofing sheets, gutters, downpipes, sewers, partition walls, exterior wall decoration, ventilation ducts, fire pipes, prefabricated houses, guardrails, steel warehouses, steel structures, rolling doors, ceiling brackets, etc.
Besides, HDG steel is also the base metal for PPGI steel. And it is popular in home appliances, such as air-conditioning accessories, back or side panels or shells of electrical equipment, freezers, etc.
