Found this info, I hope it helps, So do I understand they will JUST COVER THE RUSTED RAIL up?
Footing or Foundation
Enclosures require a solid foundation. If you already have a concrete pool deck, your contractor must determine if it meets the right thickness to support the frame of the enclosure. If not, they will pour a new concrete footing or foundation to the thickness required by zoning laws in your area.
Frame
Usually made of rust-resistant aluminum, the frame is the “skeleton” of your pool screen enclosure. Consisting of posts, beams, rails that run between the posts at the bottom of the enclosure, purlins, which are narrower strips of aluminum that run perpendicular to the beams to help form a roof, and a door, the frame forms the structure of your enclosure. It defines the roof style you have selected, either mansard, flat, gabled, domed, or sloped.
Anchors and Fasteners
The frame must be fastened to the concrete base with screws or fasteners that penetrate the concrete and hold the structure in place. These anchors help the frame resist wind.
Other fasteners attach the beams to the posts, framing to the structural gutters attached to the house, and screen panels to the frame.
If a section of the screen is damaged, a
pool screen repair company can often fix just that panel, so you don’t have to replace the entire pool screening. All fasteners should be rust-resistant.
