First: don't choose the very cheap ones.

The explanation is as follows: the cost of industrial aluminum profile = spot price of aluminum ingot+processing fee for kneading aluminum profile+packaging data fee+freight.

These are very transparent, and the cost of aluminum profiles is similar, which is obviously lower than the market price. The first possibility is that the weight per meter is less; The second type: aluminum ingots use recycled materials; The third type: expanding the blanking loss (not sold according to the practical meters).

Second: suppliers who only know how to sell information are not selected.

The explanation is as follows: prepare some goods, recruit a few wiring ladies, and do a lot of online promotion to open the business. It is our buyers who are often hurt. Most wiring girls don't know how to use it, only know the unit price. How to use it to meet the needs of customers; How to make it can achieve the highest cost performance; Which connection method is the best in different venues; They can't answer these questions accurately. Only know the cheapest profile and the cheapest connection method;

Third, select aluminum profile suppliers that focus on production.

The explanation is as follows: aluminum profile suppliers who are mainly engaged in production are generally engaged in this profession for more than 5 years, and they are also users. They have rich practical experience, have a good understanding and grasp of the quality and function of products, and will recommend products with better cost performance to meet customer needs and select convenient and practical accessories.
