Description
Best Hot Dip Galvanized Steel Plate Supplier
Looking for a reliable hot dip galvanized steel plate supplier for your business needs? Look no further than our company! Rayiwell offers the highest quality products at competitive prices. Our hot dip steel plates have immersed the steel into a bath of molten zinc. As a result, it has a zinc coating layer on the steel’s surface. The hot-dip galvanized steel plate typically includes low-carbon steel with a maximum carbon content of 0.25%. The steel may also contain small amounts of other elements such as manganese, phosphorus, and sulfur.
The thickness of the zinc coating can vary but typically ranges from 50 to 200 microns. One can check the thickness of the coating by the length of time the steel. Rayiwell uses only the best raw materials and advanced technology in our manufacturing processes.
Premium Quality Hot Dip Steel Plate
Rayiwell hot dip galvanized steel plate is a type of steel coated with a layer of zinc through a process called hot-dip galvanization. The hot-dip galvanizing process involves several steps: surface preparation, pickling, fluxing, and immersion in molten zinc. The steel is cleaned and immersed in acid to remove rust or mill scale. It is then rinsed and fluxed to prepare the surface for the zinc coating. The steel is then immersed in a bath of molten zinc, where the zinc bonds with the steel to form a protective coating.
This process creates a barrier between the steel and the environment, protecting it from rust and other types of corrosion. Also, it is highly durable and can withstand harsh weather conditions, abrasion, and impacts. Moreover, as it is highly resistant to corrosion, it requires little to no maintenance over its lifetime. So, it saves time and money on repairs and replacement. Our plates are highly versatile and sustainable as our coating increases its life span and makes it an environmentally friendly option.
In addition to their corrosion resistance, our steel plates have superior mechanical properties. They have high tensile strength, which means they can withstand heavy loads without deformation or failure. They also have good flexibility, which allows them to change their shape without cracking or breaking.
Application Of Hot Dip Galvanized Steel Plate
As a leading supplier, we provide you the plates in different levels of thicknesses and sizes. Thus, it makes them ideal for a variety of applications. They are commonly used in construction, automotive manufacturing, and industrial applications where durability and strength are important factors.
Our hot dip galvanized steel plate is also ideal for outdoor use, as it can withstand harsh weather conditions without deteriorating. This makes these plates popular for infrastructure projects such as bridges, highways, and pipelines. Also, Rayiwell Galvanized steel plates are best for the construction industry. People can use them in roofing, walling, framings, and structural components, such as beams and columns.
Further, automakers can use them in making car body panels, chassis, and suspension components. The galvanized coating protects against rust and corrosion, improving the vehicle’s longevity. They are also useful in manufacturing refrigerators, washing machines, and other appliances.

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.
