Product Description

304 Stainless Steel Bar Description

304 stainless steel bar is one of the most popular stainless steel bars across the globe for a number of reasons. Iron, chromium and nickel are the main elements that constitute 304 stainless steel. This combination gives rise to the outstanding oxidation resistance and corrosion resistance of 304 stainless steel bars. 304 stainless steel has stronger anti-rust properties than 200 series stainless steel materials as a versatile stainless steel. It also outperforms them in temperature resistance. The 304 stainless steel bar has characteristics of a smooth surface, high plasticity, toughness and mechanical strength, as well as resistance to corrosion by acids, alkaline gases, solutions and other media. 304 stainless steel bars are commonly used as manufacturing parts in fields like food processing equipment, building materials, automobile parts.

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?
