G. BOPP + Co. AG
About
G. BOPP + Co. AG, established in 1881 and headquartered in Zürich, Switzerland, is a global leader in precision woven wire mesh manufacturing with its own in-house fine wire drawing facility (Filinox) — the only fine wire weaver to maintain this capability. The company holds ISO 9001, ISO 14001, and ISO/IEC 27001 certifications and operates subsidiaries in Germany, the UK, Italy, Sweden, the USA, Korea, and China, with production split between a weaving plant in Wolfhalden and a processing facility in Zürich. BOPP's water filtration portfolio spans single-layer meshes (Betamesh-PLUS down to 5 μm aperture, Robusta for heavy mechanical loads, Duplex for balanced flow and wear, plus square weave, twilled Dutch, and plain Dutch weaves) and multi-layer sintered composites (Topmesh 2 and Topmesh 3 for harsh industrial conditions, Poremet 5-layer for exceptional fineness, Absolta for maximum porosity and flow, Composite-PLUS, and Poreflo for fluidisation applications). The company also produces ready-made filter elements including cylinders, discs, star filters, pleated filters, filter frames, and sintered discs. BOPP meshes serve primary, secondary, and tertiary wastewater filtration, CSO treatment, inside-out drum filter systems, microplastics removal, industrial water treatment, and ballast water treatment — a heritage underscored by supplying 760 filter elements per mission for NASA's Saturn V and Apollo programs.
Key Products
Single-layered woven stainless steel filter mesh with fineness down to 5 microns, offering high flow rates and exceptional backwashing properties for primary, secondary, and tertiary wastewater filtration.
Two-layer sintered mesh combining a fine filter layer with a support layer for increased stability in harsh industrial water treatment conditions.
Three-layer sintered mesh with filter, support, and additional reinforcement layers for demanding mechanical and chemical conditions in industrial water filtration.
Five-layer sintered mesh offering exceptional filter fineness with an optimal balance of stability, fineness, flow rate, and backwashing performance for advanced filtration applications.
Five-layer highly porous mesh with maximum flow capacities and reduced thickness option (Absolta D at 1.7–1.8mm) for high-throughput filtration applications.
Single-layered woven mesh designed for the most challenging mechanical demands in filtration systems requiring maximum durability and load resistance.
Single-layered woven mesh combining good flow rates with enhanced wear resistance for applications requiring both performance and longevity.
Pretensioned filter elements in cylinder or disc form, plus filter segments, star filters, pleated filters, and filter frames manufactured to individual specifications for specific micro-screen and cloth filter installations.
