Hebei Drahtgeflecht Knitted Mesh Co., Ltd. Dezhou Hengda Perforated Metal Factory

Company Introduction

For over ten years, we have been producing and exporting monofilament, multi-filament, co-knit and multi-strand knitted wire meshes, and series processed filter products. Our products are mainly used in Oil & Gas Industries; Drilling (Oil & Water well); Petrochemical & Process Industries; Shielding, Sealing of Auto Engine Exhaust System; Air Filters, Breathers and Separators; similar high temperature applications. The knitted mesh filter products work efficiently to remove the mists and liquid droplets entrained in thermal heating filtration system. Knitted wire mesh is made of different materials including aluminum, copper, monel, Teflon, plastic, stainless steel, nickel, metal alloys as well as PP, PTFE, FRP.

Supplied forms mainly are: knitted wire mesh rolls, tubes and tapes, blankets, pad demisters, mist eliminators, compressed gaskets, breathers, shieldings, washers, mufflers and other filter elements.

Why Knitted Mesh for Thermal Filtration?
Advantage of knitted wire mesh is its unique construction. Knitting produces an interlocking-loop pattern. The final knitted mesh is in the structure of inter-connecting loops, and it similar to a long knit sock. In this configuration, each loop is an integral part of its neighbors with each supporting the other. When a mesh or mesh element is compressed, stretched or bent, and provided that exertion is not past the material's yield point, this integrity allows the element to spring back to its original form. Hence, it can work efficiently under high temperature work environment.

Our knit wire diameter is commonly range from 0.11mm to 0.35mm. But for special applications, knit wire as small as 0.03mm or as large as 0.8mm in diameter is available.


Metal wire meshes mainly serve the following industries: cleaning of the filter, plastic and die, mufflers, shock absorber mounts, soundproof generator pad, air conditioning humidifier pad, to capture the flame of the wireless signal shielding, sealing in harsh environments.

Industries Served:

Protection of Diesel fuel injections
Radio frequency interference shields
Shock absorbers (Cuhion steel), Vibrations mounts
Transfer of normally, exhausted waste heat
Mufflers of pneumatic tools.
Flame arrestors
Abrasive copper mesh for cleaning plastic extrusion screws, barrels, dies, moulds and machine parts. (Gauze cleaner)
Soundproofing mats for generators
Humidifier mats in air conditioning.
