1. The first is stainless steel: door stainless steel plate is generally used 304 # and 206 #, the number represents the degree of stainless steel rust, most of the current JS selected 206 # (or 20 ? #) but its rust resistance is poor, encountered Acid (such as floor cleaner) will play matt or rust (especially at the weld joint)
2. Door locks: try to lock the locks that cannot be unlocked with the keys and lock them out of the door (don't choose locks like the big wooden doors of the new garden. This kind of lock is easy to get into the house, dangerous)
3. Hinge: Welding must require the manufacturer to fully solder and polish

7. Look at the quality We can see that the shadow gauges on the stainless steel plate of the door are not regular (thicker and more structured), and whether the weld is flat (process level)
