The focal points in the field of constructional elements /construction products are:

  • Testing the anti-slip properties of floor coverings
  • Testing ladders; investigating accidents and exploring questions of a technical matter on the use of ladders
  • Studying the mechanical safety of constructional elements such as windows and doors
  • Testing temporary constructions (scaffolding) and temporary devices for constructing and maintaining buildings, especially collective protective equipment, including lift working platforms
  • Technical safety studies of construction products that indicate traffic routes and secure them
  • Structural analyses and stability proof from testing and calculation
  • Studying transport safety and practicality for use of large-area enclosure elements for walls, ceilings and roofs
  • Analysis of damage and injury resulting from constructional element failure, especially as related to occupational accidents
