1. The price varies. When customers want to buy metal flex hose, they always want to ask a few more companies and compare the prices, but after asking, they have a headache. The prices of the three companies are too high, and the prices are too low. , I don't know why the difference is so big? First of all, the basic parameters and materials of the product should be unified, the gas meter hose (several layers), the mesh sleeve (several layers), whether the material is 304 stainless steel, what material and what standard are the joints of the connection form, and the specifications and materials are determined. After that, it will be better to have a unified quotation. Price is only part of the user's choice

2. The origins are endless. Many self-proclaimed manufacturers have many origins. Users do not know which one to choose. Considering after-sales issues, it is recommended that users choose a place closer to themselves.

3. How to guarantee after-sales? This is indeed a key factor in the strength of the manufacturer. Good companies have dedicated after-sales personnel. This can only be determined by users themselves.

4. Is the actual inspection necessary? It is necessary to conduct an on-site inspection when ordering in large quantities, so as to facilitate long-term cooperation in the future.
