PP Honeycomb Protection Board in Automotive Plants: Protecting Floors During Line Changes
Automotive line changes apply heavy point loads to production floors. This guide covers thickness from 2 mm to 12 mm, AGV routes and a plant trial plan.
Automotive plants change lines, move tooling and install equipment on floors that also carry AGVs, tugs and heavy components. Works are scheduled around production, and the floor is part of the production asset. This article looks at protecting floors during line changes and installation. The focus is heavy point loads, AGV routes and working to production schedules.
The floor is part of the production asset
In an assembly plant, floor damage is not cosmetic: a cracked slab or a damaged coating affects AGV navigation, trolley routes and safety. Repair means stopping part of the line.
A rigid PP honeycomb protection board spreads the concentrated loads from tooling and equipment feet, protecting the slab and coating during installation.
Because the panels do not absorb oil, they suit an environment where fluids are part of normal operation.
Thickness choices from 2 mm to 12 mm
Automotive installation involves tooling, presses and component racks, so the upper part of the 2 mm to 12 mm range is usually required.
For pedestrian routes a mid thickness is enough. Under tooling feet, press bases and equipment set-down points, the thickest boards give the spreading that protects the floor.
| Board group | Typical thickness | Where it earns its place | Watch-outs |
|---|---|---|---|
| Light-duty panel | 2-3 mm | Pedestrian routes beside the line | Unsuitable under tooling |
| General line panel | 4-6 mm | Assembly areas with trolley and tug traffic | Keep AGV routes consistent |
| Heavy-duty panel | 8-10 mm | Tooling set-down and equipment feet | Check coating tolerance |
| Maximum protection | 12 mm | Press bases and heaviest installation loads | Confirm slab capacity before loading |
AGV routes, tooling feet and production schedules
Keep AGV routes clear or protect them without changing the surface the AGV navigates on, because guidance systems depend on consistent floor conditions.
Protect tooling set-down zones as carefully as the route, since that is where weight is applied repeatedly in the same place.
Plan around production: protection is placed and cleared in the windows between shifts or during planned downtime, so handling speed matters.
How honeycomb board compares with steel, ply and sheeting
Steel plate handles the heaviest loads but is slow to place and a manual-handling risk during a tight installation window.
Plywood absorbs oil, crushes at the edges and is often damaged beyond reuse after a single line change.
Plastic sheeting is useless under tooling feet. A PP honeycomb board gives spreading at a weight that can be placed and cleared quickly.
A practical trial plan for automotive works
Protect one installation zone and leave a comparable zone on the current method. Inspect after each set-down and at each shift change.
Run a tooling set-down test on a sample panel, then lift and inspect the slab and coating.
Record placement time and any coating damage, because in a production environment those decide whether the method is used again.
What to include in a protection board enquiry
State the slab and coating type, the tooling weights, the AGV arrangements and the production windows. Ask for the recommended thickness for concentrated tooling loads.
Confirm oil resistance and fire performance, and ask about custom sizes for standard bay grids.

Final takeaway
In automotive plants, protect tooling set-down zones, keep AGV routes consistent, and use the thick end of the range under concentrated equipment loads.
