OUR CATALOGUE
WOVEN MESH






Woven wire cloth
(with square meshes)
- Stainless steel wire cloth
- Brass wire cloth
- NiCr wire cloth

Description: Each warp wire crosses alternately above and below each weft wire, thereby they form square mesh. Warp and weft wires generally have the same diameter.
Application: They are used in mining, food, pharmaceutical industry as sieves, separators, different filters etc.
Characteristic: aperture width, wire diameter, open screening area, roll width, material.
Material: Woven wire clothes are generally made of stainless steel AISI 304, AISI 321, NiCr and of non-ferrous alloys (brass).







Single wire cloth

Description: This kind of wire cloth is made the same way as woven wire cloths with square meshes but warp and weft wires form a rectangular mesh.
Application: They are used in pulp and paper industry and in asbestos and slate making.
Characteristic: aperture width, wire diameter, open screening area, roll width, material.
Material: Woven wire clothes are generally made of stainless steel AISI 304, 321 and of non-ferrous alloys.







Conveyer mesh

Description: This type of mesh is woven of round wires (weft) and of single, double etc. cord strands (warp). It has square or rectangular meshes.
Application: High-alloy and heat-resistant steel wire conveyor meshes are used mainly for drying devices in food and chemical industries.
Characteristic: aperture width, weft and warp wire diameters, number of cords in weft strand, number of wires in one cord, roll width, material.
Material: The woven conveyor meshes are made of stainless steel AISI 304, 321 or of heat-resistant steel.







Crimped wire mesh




Crimped wire mesh is usually used for reinforcement of ferroconcrete items or brickwork; it is used also as fencing, frames for greenhouse, cages for birds or animals etc. This kind of wire mesh is made of carbon iron wire, galvanized steel wire or stainless steel wire. Crimped wire mesh is woven after wire being crimped. Wire diameters are 3; 4; 5; 6,5 mm.








Conveyer belt




Conveyer mesh belts are used in conveyer lines for drying of various materials and food products. They are made of stainless steel AISI 304, 321 or of heat-resistant steel.







Chain Link Fence,
Hexagonal Wire Netting




Chain Link Fence is used as fences for playground and gardens, super highway, railway, airport, port, residence, etc. Also can be used for breeding of animals. Hexagonal Wire Netting is divided into galvanized hexagonal wire, pvc-coated hexagonal wire netting It is widely used in construction building, as reinforcement splinter proof of glass, cement concrete, laying of roads etc.

WELDED MESH








Welded wire mesh


Description: Welded wire mesh is the most economic one among other welded wire mesh products and finds the most popular uses. It is made of low-carbon wires with diameters from 1.2 mm up to – 5.00 mm and has square or rectangular meshes.
Application: Welded wire mesh is used for reinforcement of ferroconcrete items or brickwork; it is used also as fencing, frames for greenhouse, cages for birds or animals etc.
Characteristic: aperture size, wire diameter, roll width and length, material
Material: galvanized and non-galvanized low-carbon steel
POLYAMIDE MESH








Plastic / polyamide mesh





Plastic meshes are nontoxic and chemically inert. They are used in food industry. These meshes don’t screen electromagnetic waves that’s why they used in construction and indoors where the electromagnetic signal distortion is not allowed.
FILTER MESH







Dutch/Filter wire cloth
Description: Wire filter cloth, woven in a plain weave pattern having few and thicker warp wires and many thinner weft wires, beaten closely together. Twilled Dutch is of a similar construction to plain Dutch i.e. fewer thick warp wires, many thin weft wires, except the weave pattern is twilled which allows the maximum number of weft wires. Dutch twill is a surface filtration media and allowing the smallest openings. Smooth surface, very solid, specially used for finest filtration.
Application: Filter weaves made from metal wires are used for separation of solids and clear filtration of liquids, as in the cleaning of fuels or hydraulic liquids, or in water treatment in chemical, mining industry etc.
Characteristic: aperture width, wire diameter, open screening area, weaving type, roll width, material.
Material: Filter wire clothes are generally made of stainless steel AISI 304, 321.







Filter knitting




Description: Its kind of arm knitted of high-alloy stainless steel round wire. 
Application: Filter knitting, as a component of mesh impingement plate, serves for gas and steam separation in rectifying stills, scrubbers, separators in gas-and-oil producing industry.
Characteristic: wire diameter, number of loops, coil length.
Material: Filter knitting is made of stainless steel AISI 304 and 321.







Filter elements




Filter elements are used for the filtration of fluids and made of different kind of wire cloth. There are many types of filter elements; they can be smooth or pleated, simple round or cylindrical, single-layered or multi-layered etc. Filter discs have different forms, like round, square, oval and can be made according to customer's requirements. According to material and application the following joints are possible: spot welding, cylindric seem welding, traditional soldering, adhesing.
