Hot Dip Galvanized Sheet Description
Hot dip galvanizing is to make the molten metal react with the iron substrate to produce an alloy layer, so that the substrate and the coating are combined. Hot galvanizing is to pickle the steel and iron parts first. In order to remove the iron oxide on the surface of the steel and iron parts, after pickling, it is cleaned by ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank, and then sent into the hot dip plating tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. Compared with other metal protection methods, the hot-dip galvanizing process has advantages in the protection characteristics of the combination of physical barrier and electrochemical protection of the coating, the bonding strength of the coating and the substrate, the compactness, durability, maintenance-free and economy of the coating, and its adaptability to the shape and size of the product. At present, hot-dip galvanized products mainly include steel plates, steel strips, steel wires, steel pipes, etc., of which hot-dip galvanized steel plates account for a large proportion.
The production process of hot galvanizing is as follows:
Mother material → degreasing → water washing → pickling → water washing → rinsing → flux solution → drying → hot galvanizing → cooling → inspection → packaging
Scope of Application
For a long time, hot-dip galvanizing process has been favored by people because of its low plating cost, excellent protection characteristics and beautiful appearance. It is widely used in automobile, construction, household appliances, chemical industry, machinery, petroleum, metallurgy, light industry, transportation, electric power, aviation and marine engineering and other fields.

FAQ
1. What are your main products?
We primarily deal in carbon steel (hot-rolled/cold-rolled sheets, coils, pipes, and bars), structural steel (angle bars, channel steel, I-beams, H-beams, square/rectangular tubes, etc.), galvanized products (galvanized sheets, coils, pipes, and profiles), and aluminum products (sheets, coils, profiles, and bars). We can also supply other steel varieties based on customer requirements.
2. Are you a manufacturer or a trader?
We are a comprehensive service provider integrating trading, processing, and distribution. We maintain close partnerships with major steel mills in Vietnam and the surrounding region, ensuring a stable supply chain. Additionally, our in-house processing center offers value-added services, combining the flexibility of a trader with the service capabilities of a processing plant.
3. Do you accept small-batch orders? What is the minimum order quantity (MOQ)?
Yes, we support small-batch and trial orders. The MOQ is typically one container (approx. 20–25 tons), depending on product specifications and dimensions. MOQs for aluminum products can be lower; please contact us for details.
4. What is the typical delivery time?
For standard products, delivery takes 15–30 days after receipt of the deposit, depending on order volume, product type, and current production scheduling. Stock items can be delivered sooner. Delivery times for customized orders will be longer, and we will inform you in advance.
5. What payment methods do you accept?
We generally accept T/T (Telegraphic Transfer) and L/C (Letter of Credit). More flexible payment terms can be negotiated for long-term clients. Specific ratios (e.g., 30% down payment and 70% balance) can be adjusted based on the order value and credit status.
6. What processing services do you offer?
We provide services such as cutting, punching, bending, welding, uncoiling, and leveling. We also offer customized deep processing of profiles based on technical drawings. All processing is performed in-house to ensure quality control and timely delivery.
