Different customers, for manufacturers, the production and operation costs are different. For example, the number of customers' purchases, whether customers have customized needs, how far customers are from the factory, whether the customer's archives have elevators, and the customer's choice of library bookshelf style. According to these conditions, the manufacturer will comprehensively calculate the cost and quote the customer after adding their own profits.

2. At different times, the quotations of manufacturers may be different.

The main production material of library bookshelves is cold-rolled steel plate, which will change with the change of steel market price, so the inquiry from manufacturers in different periods may get different prices. For example, in May and June of this year, the price of steel plate rose by more than 25% a month, and manufacturers had to adjust the price of the shelf.

3. Different product quality

Different library bookshelf manufacturers adopt different technical standards, and the product quality is also very different. For example, choose steel brand, plastic powder brand, design structure, cutting, folding and welding process and so on. Don't think that the price should be the same just because the appearance is similar. Only by careful comparison can we find out the difference.

The factories are located in different areas.

Factories in that province have a great influence on their production costs, such as Shanghai and Henan. Even if it is the same thing, it is normal that the price difference between the two places is 2-3 times. Therefore, it is normal that the factory is in different provinces and the product prices are different.
