How should I frame artwork that will hang in a lobby?
Two things that you will also want to consider given that the item will be on display in a public location:
1) Using acrylic instead of glass will help to reduce the weight of the finished piece, and also provides shatter-resistance, which can be very desirable from a safety and liability standpoint. We also have acrylics with an abrasion-resistant coating to help prevent scratches and allow cleaning with standard glass cleaner and paper towels.
2) "Security Hangers" are available, which can be useful for hanging pictures in public areas. Since they attach positively to the wall, they help to hold the picture straight (and on the wall) in case of casual contact or cleaning by janitorial staff. Also, there is a special hardware component that holds the bottom of the frame to the wall that requires a hanger "key" to disengage, deterring casual attempts to remove the item from the wall.
