Wire cloths according to DIN 4192
HL wire cloths in square and long mesh finishHL wire cloths in square and long mesh finish are crimped and mechanically woven under pre-stressing to a tight compound. This gives the cloth a high vibration strength and long service life.Materials

Spring steel, Material No. 1.0500
Manganese cast steel, Material No. 1.0516
Stainless steel
Heat-resistant steel

Wire grids according to DIN 4192 Form E (Type Dovex)
HL wire grids, Type Dovex Form EDovex wire grids made of round wire have a completely smooth screen surface. Due to one side smooth surface there is given only little abrasion resistance to the screening material having therewith a favorable influence on the service life of the grid.
Through double anchoring at the wire crossings, the wire grid is additionally provided with a tight mesh compound enabling to give with it a constant mesh strength and a precise mesh positioning.Materials

Wire grid according to DIN 4192 (Type Rastex)

HL wire grids, Type Rastex

RASTEX wire grids made of high-profile wire have a completely smooth screen surface. Mesh precision is here also ensured by double anchoring at wire crossings. Through the highly-rising wedge profiles, clogging and sticking grain can be avoided.

Materials

Manganese cast steel, Material No. 1.0495

Wire grids according to DIN 4192 (pressure-welded grids)

HL wire grid, type pressure-welded grid Form F

The round steel bars connected by using electric resistance welding give the screen panel a tight mesh compound. By this a fixed and completely precise mesh uniformity is provided.
