From Dura Trac Nursery
The Clearspan Nursery floor is completely self supported in all directions and no additional support is required. The frame and floor are welded together and completely plastisol (PVC) coated to prevent rust and corrosion. It can be ordered in sizes up to 12 feet long (with a limited width). There are convenient options available to customize the floor to your needs, such as an open end for easier cleaning of the alleyway. The Dura Trac Clearspan Nursery Flooring supports pigs up to 100 pounds.
