In the early days, we use LZ-70 system as folding doors; and in the past few years we have been using LZ-75 system as folding doors.

Since last year, we started promoting LZ-68, which is a even more premium system.

There are three major advantages for this LZ-68 system:

1. Premium hardware KSBG

2. More flexible when it comes to opening styles: it could be 2+0/0+2, 2+2, 4+0/0+4, 0+6/6+0 etc, which are not available from LZ-75 system. The latter can only do 3+0, 0+3, 1+3, 3+1, 5+1, 1+5 etc.

3. It has pinchproof function, safer for kids.

At the mean time, LZ-75 is still available as a substitute for more economical option.
