Pressure Locked Grating (Steel)

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.
