Debris Netting – Fine Mesh Containment Nets
AGS debris netting is a fine-mesh net that catches tools, fixings, concrete pieces and other small objects falling from slabs, roofs, bridges and scaffolds. It is used on its own to protect people and property below, or laid over a personnel safety net so that both people and small materials are caught.
- Fine mesh
- Liner for safety nets
- UV-stabilised
- Rolls or cut to size

Why personnel nets need a debris liner
A personnel safety net to EN 1263-1 may have a mesh of up to 100 mm. That is ideal for catching a person, but a hammer, a bolt or a piece of concrete passes straight through. Wherever people, vehicles or property are below the work, a fine debris net is added. Laid over a System S construction safety net, it catches small objects while the safety net below still catches people.
Debris nets on their own
Not every job needs personnel protection, but many need material protection. Bridge maintenance above traffic, roof repairs above a shop entrance, facade cleaning on a busy street: in each case a debris net stretched below or beside the works keeps falling objects off the public. For vertical containment on scaffolds, see our scaffold netting; for loose stones and panels on existing buildings, see facade protection nets.
Choosing the mesh and material
The mesh opening is chosen by the size of the smallest object that must be caught. Liners over safety nets usually use around 20 mm. For dust, grit and very small fixings, a finer knitted mesh is used. Debris nets are made from UV-stabilised HDPE or polypropylene, which keeps them light and easy to handle. Edges are reinforced with a hem and eyelets or a rope so that the net can be tied at short intervals without tearing.
Keep the net empty
Debris nets are not storage. Concrete, sand and fixings add weight, increase deflection and hide damage. Plan for the net to be emptied every day or after each phase of work, and check it for tears and burn marks, especially near welding and cutting. Our article on safety net inspection and testing includes a checklist you can use for debris nets as well.
Applications
- Liner over System S safety nets under slabs and roofs
- Bridge decks above roads, railways and waterways
- Protection of pedestrians and vehicles below facade and roof works
- Demolition and renovation of buildings next to public areas
- Inside stadium and hall roofs during maintenance
Choosing the right net
| Safety net only | Debris net only | Safety net with debris liner | |
|---|---|---|---|
| Catches a person | Yes | No | Yes |
| Catches small objects | No, mesh up to 100 mm | Yes | Yes |
| Typical use | Personnel protection | Material protection | Both, over public areas |
Installation
- Decide whether the debris net is used alone or as a liner over a safety net.
- As a liner, lay the debris net on top of the safety net and tie it to the border rope at short intervals.
- On its own, fix it to a frame, scaffold or anchors that can take the weight of the expected debris.
- Overlap adjacent widths so nothing can fall through the joints.
- Plan regular emptying: debris adds load and must not stay in the net.
Inspection, maintenance and service life
- Empty the net of debris daily or after each work phase.
- Check for tears, burnt spots from welding and loose fixings before each shift.
- Replace sections that are torn or brittle from UV exposure.
- Never use a debris net as a personnel safety net.
Frequently asked questions
Can a debris net replace a safety net?
No. A debris net is designed to catch objects, not people. Where people can fall, use an EN 1263-1 safety net and lay the debris net over it.
What mesh size is used for debris liners?
Liners over safety nets are usually around 20 mm. Finer meshes are used where dust or very small fixings must be held back.
Do you have flame retardant debris nets?
A flame retardant version can be produced on request. Tell us the fire classification you need.
Is debris netting sold by the roll?
Yes. Debris netting is supplied in rolls or as nets cut and finished to size.
