Important remarks for reference before you design the door production

 

1. Our magnet options are great but please bear in mind that these are not electromagnets,

they are the strongest ndfeb magnets available.

 

2. N52 Magnets are hot selling in USA, there are also N54 / N55 as “being called” global markets,

but actually that is only N52 made on top property level.

 

3. They're incredibly strong but please bear in mind the size, weight & windage of your door.

 

4. Door stops top & bottom are advised for anything other than a small, light door.

 

5. In order to save the cost, now many door customers use N50 instead of N52 Neodymium Magnet,

Even N35 very common as well.
