Staircase railings can be with vertical or horizontal balusters, which number will depend on the purpose of the railing. In general, vertical balusters are safer than horizontal when you have small kids at home.
The staircase railings with glass are made of aluminum with 8 mm laminated glass panels. Laminated glass is very difficult to break, but when it does, it remains whole like the windscreens of the cars. This is another safe option when you choose your railing.
