Description
Top Manufacturer & Supplier of Hot Dip Galvanized Steel Plate
Galvanization is a manufacturing process that uses zinc for coating a flat piece of metal. This gives out the best quality galvanized plate or sheet. For hot dip galvanized steel plate, the hot-dip galvanization method is the most reliable way of protecting steel materials against corrosion.
Galvanized steel sheet metal and plate are commonly useful in applications where industrial applications prefer corrosion resistance. It provides a lifespan of more than 20 years at reasonable temperatures. In addition, it gives out many qualities and features.
At HK Aluminum, we supply wholesale hot dip galvanized steel plates of the best quality. If your business is in search of an affordable galvanized steel plate price, we’re here to help. Order the best quality steel plate products from our wholesale suppliers.
High Quality Galvanized Steel Plate
Galvanized steel sheet and plate offer superior qualities and perfect resistance to corrosion. Also, they have extensive molding and coating capabilities. Get the best grade of hot dipped galvanized steel plate and sheet here in bulk.
When you apply a protective coating of zinc to iron or steel to prevent premature corrosion and rust. Hot-dip galvanization protects the material from rust. Moreover, it provides an easy inspection process.
Users can cut, machine, and weld the galvanized sheet or plate using the same methods as ordinary steel. However, adequate ventilation is necessary to avoid fume inhalation during heating. Have a high quality steel plate for bulk projects.
Moreover, they are cost effective which can save a lot of cost if your business is buying in bulk. Using galvanized plates can reduce maintenance and increase life expectancy. Therefore, purchasing at HK Aluminum is the ideal choice for everyone.
Applications of Hot Dip Galvanized Steel Plate
Hot-dip galvanized plates are primarily useful in the construction of roofs, doors, chassis, trunk lids, windows, and rolling doors. Also, for hanging frames, fuel tanks, car covers, metal sashes, and color-coated substrates, they work effectively.
Hot dip galvanized steel plate is commonly used for electrical equipment such as freezers, refrigerator bases and enclosures, and kitchen appliances. Moreover, the main purpose of these plates is to provide increased corrosion protection without the need for painting.

Product Specification:
- Galvanized hot dip steel plate DC51D,also named as hot dip galvanized steel sheet DC51D+Z and hot dip zinc coated steel plate and coil DC51D+ZF.Under Q/BQB 420 steel standard, there are DC51D+Z,DC51D+ZF which is for bending and profiling quality,DC52D+Z,DC52+ZF which is for drawing quality,DC53+Z,DC53+ZF which is for deep drawing quality,DC54D+Z,DC54D+ZF which is for special deep drawing quality,DC56D+Z,DC56D+ZF which is for extra deep drawing quality.
- DX51D stands for galvanized steel sheet. The first D means flat steel for cold forming. The X means the rolling state is indefinite. 51 is the series number of the steel. The second D means hot dipped galvanized.
- If the X become C, namely DC51D, it means that the substrate rolling state is cold rolling. While DD51D means that the rolling rolling state of the substrate is hot rolling.
- What’s more, it’s easy to see DX51D-Z, DX51D-ZF or DX51D-AZ. The Z means that the galvanized coating is Zinc. ZF means that the galvanized coating is Zn-Fe alloy. AZ means that the galvanized coating is galvalume.
- DX51D galvanized coils are produced according to EN 10346. The thickness of the zinc coating varies depending on consumers’ requirements.
- DX51D galvanized coils are widely used for the production of steel structures, roofs, window profiles, drainage and ventilation systems, roads barriers, bridges, and household appliances (cases and internal parts).
- DX51D steel products are produced in coils 0.4-1.6 mm thick and 950-1250 mm wide. The inner diameter of the coil is 600±20 mm and outer diameter is up to 1300 mm. Coil weight is up to 8 tons. Coils are supplied with cut edges (mill edges are also possible).
- Chemical composition and mechanical properties according to EN 10346.
Note: Tolerances for dimensions and shapes are outlined in EN 10143 (tolerances for width are for coils a minimum of 0.7 mm thick).
Note: Requirements for forming and weldability of finished products should be taken into consideration when ordering the weight of zinc coating.
