Panels are dimensioned to DIN 24537-3 design principles over a defined support span; exact allowable UDL and point load depend on thickness and span and are confirmed from the manufacturer's load table rather than a single generic value.
Typical applications
- Walkways and platforms
- Chemical and process plants
- Water and wastewater
- Trench and drain covers
