Our sister company Steinhaus GmbH offers various steel screen panels. These are categorized as «standard wire cloth» and «self-cleaning wire cloth»
REKORD sieve trays
Standard sieve bottom with solid performance characteristics. Precise grain separation, even with elongated and fishy screenings, thanks to square screen openings. Good mesh structure even with progressive wear.
REKORD sieve trays are woven sieve trays with square meshes, plain weave in accordance with DIN 4185-1, for dividing screenable goods into the desired particle sizes on screening machines, with or without tensioning devices, on screening drums or other screening equipment.
SOLIDA pressure welded mesh
SOLIDA press-welded screens are press-welded screens made of round wires for grain separation of highly abrasive screening materials with mesh openings of 10 to 200 mm. They are vibration-proof, have large, open screening surfaces and achieve long service lives.
The screen bottom material is a highly wear-resistant special steel with a tensile strength of 500 to 600 N/mm². Steinhaus also supplies SOLIDA screen panels in corrosion and heat-resistant stainless steels. The particularly large welding depth ensures a firm mesh bond until the screen bottom is completely worn.
LONGVITA®
LONGVITA® screen panels are one-sided smooth screen panels made of round wires, with a smooth top side and a large open screening surface. They are particularly suitable for classifying abrasive screenings with mesh openings of 5 to 100 mm, as well as for a higher proportion of coarse-grained material in the boundary grain range.
Chrome-nickel steel. Special materials on request.
Self-cleaning wire mesh
Wherever technically possible, polyurethane screens have almost completely replaced steel screens.
Nevertheless, steel screens are the screening medium of choice in many applications and cannot yet be replaced.
A major advantage of wire screens is the larger open screening surface compared to polyurethane screens. If, for example, a very high throughput rate is to be achieved with a small screening machine, wire screens can be the solution.
As the screenings fall onto a narrow, hard wire, cohesive screenings break apart very easily. The use of wire screens is advisable for dry screening of sticky screenings.
The positive effect of self-cleaning is perfected with Steinhaus self-cleaning wire mesh.
HARFEN: Fabric-like sieve trays
For screening moist, difficult-to-screen material with a predominantly round or cubic grain shape on screening machines and other screening equipment. Applications e.g. for moist sand, sand-lime brick, marl, magnesite, dolomite, olivine, fireclay, phosphate, fertilizers, salts, plastic granulates, etc.
With HARFEN screen panels, self-cleaning is achieved by the knocking effect of the screenings and by the natural vibration and cutting action of the screen wires.
HARFENs significantly increase the throughput rate of the screening machine due to the large free screening surface.
HARFEN are manufactured in 3 versions:
- HARFE-WS: made of corrugated longitudinal wires with cross-connections at any distance that can be adjusted to the substructure of the screening machine.
- HARFE-G: made of straight longitudinal wires, with cross-connections at regular, fixed intervals.
- HARFE-G-PLAST: made of straight longitudinal wires with elastic polyurethane cross-connections for highly abrasive screenings and when the flexible cross-connection is to prevent bridging.
TRIA® TRIAPLAST® SERPENTI: Fabric-like sieve trays
TRIA and SERPENTI screen panels have an excellent self-cleaning effect due to the relative movement of the screen wires.
In contrast to harp sieves with slotted sieve openings, TRIA and SERPENTI achieve good sieving results even with elongated grain due to the horizontally corrugated sieve wires.
SERPENTI sieve trays have approximately square and TRIA sieve trays have approximately triangular sieve openings.
Due to their good self-cleaning effect, these fabric-like sieve trays are used successfully in the stone and earth industry, ore preparation and mining.

- TRIAPLAST
- TRIA ® harps
