Product Description

3A21 Aluminum Plate Description

3A21 aluminum alloy, also known as A921 aluminum alloy, is an aluminum alloy material whose main component includes aluminum and a small amount of other alloy elements such as manganese, copper, chromium, and Zinc. 3A21 aluminum plate has good tensile strength and yield strength and can meet applications with various strength requirements. 3A21 aluminum alloy has good corrosion resistance and can be used for a long time in humid and corrosive environments without rusting easily. Besides, 3A21 aluminum plate can be subjected to various surface treatments, such as anodizing, spraying, chrome plating, etc., to increase its surface hardness and decoration. Another thing that makes 3A21 aluminum plate a favorable option is aluminum alloy is light in weight and low in density compared to other metals. It is an ideal lightweight material and is suitable for product designs that require light weight.

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.
