Pressure Locked Grating (Steel)

Application

Suitable to use in a wide range of architectural projects:


  • Standard for platforms, landings and walkways.
  • Anti-slip are used in areas where there is an increased risk of slipping.
  • Narrow-pitch for floor coverings, e.g. before doorways, in pedestrian areas or in public areas.
  • Heavy-duty are used for vehicle applications and loads according to EN 1991/ DIN 1055-3 or DIN 1072.

Description

Steel pressure-locked gratings, available in a wide range of variants.


Features and benefits:

  • Good light and air permeability.
  • Suitable for use in a variety of applications.
  • Provides a high load capacity and torsional rigidity.
  • Also available in stainless steel and aluminium variants.
  • Suitable for areas which require an aesthetic appearance.
  • Pressure-locked gratings with bearing bars up to 50 x 3 mm are edged with a shaped, twice ribbed banding bar or a flat material as standard. Such gratings can also be edged with a T-profile. Pressure-locked gratings with bearing bars larger than 50 x 4 mm are edged with flat material as standard, other options may be available.
  • Production method ensures that end meshes of the same size as the grating are produced, bearing and crossbars are flush with the adjacent grating.

Type:

  • Heavy-duty can be manufactured for many applications depending on the clear span.
  • Anti-slip, punched up on the upper side. Through a variety of shaping options and combinations, rating groups up to R13 according to BGR 181, confirmed by type approval testing for various types of gratings.
  • Narrow-pitch are designed to be anti-slip when installing outdoors. The rating group of R10 according to BGR 181 must be met by additional profiling of the crossbars.
  • Treads consists of a specially shaped and perforated nosing, a tread made of pressure-locked gratings and perforated side panels. To facilitate site assembly, the end plates are provided with a plain hole and slotted hole each side. Perforated nosing edges increase the bearing capacity of the stair treads and significantly contribute to a safe footing on a staircase. Treads are manufactured in accordance with DIN 24531-1.


Construction:

  • In slotted bearing bars, stable cross bars are inserted.
  • The high pressure and the slit formation of the bearing bars ensure a secure connection for a warp-resistant structure.
