Door closer manufacturers teach you how to choose fire doors

How to choose a cost-effective fire door I think this is a headache for many consumers. Let me give you some things to pay attention to when choosing a fire door.

1. Accessory issues. From the professional point of view of our Fulda door closers, this kind of door and window product accessories have greatly improved the product itself, so we need to pay attention. The door hinges and door closers are both A must for life protection on fire doors. And for merchants, these places can save a lot of profits, so you must pay attention when purchasing!

2. You can't choose some three-no products for the sake of cheapness. The products produced by such products all have hidden quality problems. So when we meet such manufacturers selling, we must not start to buy, just follow what he said! When actually buying, we also need to see the qualifications of the merchants, printing licenses, test reports, etc. We must make it clear that fire doors are life-saving products in case of danger. Even the details of the entire product such as door closers and fire doors cannot be ignored!

3. Pay attention to after-sales problems when purchasing, for example, if the door closers of fire doors leak oil, the after-sales problems are not included, because fire doors often have the problem of oil leakage from door closers. At that time, merchants will be needed to deal with the after-sales, otherwise the whole door will be ruined if the merchants don't come!
