Spiral Treads.

Type AP

Limited space in the project to install a conventional staircase? Our perforated panels can also be produced as perforated spiral treads, making them widely applicable in industrial environments where space is limited. Is a high coefficient of friction and good drainage necessary? We have many different hole patterns that meet the most stringent requirements. Perforated spiral treads are usually used in spiral staircases.

  • Ideal when space is at a premium
  • More grip through punched hole design
  • With or without welded-on socket
