3xxx Serious Aluminum Alloy Profiles are high-performance metal profiles independently developed and produced by Shanghai Perfect Industry Co., Ltd. The core feature of this series is its aluminum-manganese alloy composition (with manganese content ranging from 1% to 3%), which endows the products with excellent comprehensive properties. They possess outstanding corrosion resistance, especially superior resistance to atmospheric corrosion and seawater corrosion, and also exhibit good formability, weldability, and toughness. While retaining the lightweight advantage of aluminum alloys, they have stable mechanical properties, making them an indispensable key material in fields such as construction, transportation, decoration, and electronic equipment that require balanced performance in corrosion resistance, processability, and reliability.

1.Q: Do you provide samples? How to apply for them?
A: We offer free standard samples (A4 size for plates or 300mm length for profiles), and customers only need to bear the shipping cost. For customized size, cross-sectional shape, or surface treatment samples, a certain sample fee will be charged (the sample fee can be deducted from the formal order payment later). You can contact our sales team via email or phone, provide your company information, product specifications, and sample requirements, and we will arrange sample delivery within 3-7 working days.
2.Q: What payment methods are supported?
A: We support international common payment methods such as T/T (Telegraphic Transfer) and L/C (Letter of Credit). For long-term cooperative customers or large-batch orders, we can negotiate more flexible payment terms based on actual conditions.
3.Q: How to ensure product quality during transportation?
A: In addition to adopting professional packaging suitable for long-distance transportation, we cooperate with logistics companies experienced in international transportation to minimize the risk of product damage. Meanwhile, we can purchase transportation insurance for customers upon request to provide double protection for product safety.
4.Q: Are you a manufacturer or a trader?
A: We are a group company integrating production, sales, and warehousing, consisting of two trading companies, three warehouses, and one factory. We have our own independent production lines and a large standing inventory, and are also authorized distributors of several state-owned aluminum factories in China. Shanghai Perfect Industry Co., Ltd. is mainly responsible for overseas sales, enabling us to offer factory-direct prices and professional product services.
5.Q: Can you provide customized processing services?
A: Yes, we support customized processing according to customers' specific requirements, including cross-sectional shape, size, length, surface treatment, and packaging. Our engineering team will work closely with customers to develop optimal customized schemes and ensure product quality meets expectations.
•Free Standard Samples: Size is A4 (for plates) or 300mm in length (for profiles), with customers only responsible for shipping costs.
•Customized Samples: Support customized samples of different sizes, cross-sectional shapes, and surface treatments. A certain sample fee is charged, and the specific fee standard will be quoted based on customization requirements.
•Sample Delivery Time: 3-7 working days after confirming sample requirements and receiving shipping costs (or sample fees).
•Sample Confirmation: Provide detailed test reports for samples, including material composition, mechanical properties, and surface quality data, to help customers verify product suitability.
