What ZM SILESIA does

ZM SILESIA Spółka Akcyjna is a Polish non-ferrous metals processor with origins dating to 1844, operating from its headquarters in Katowice and a second production site at Huta Oława. The company manufactures zinc-titanium sheet (SilesiaZINC brand) to PN-EN 988 standard in flat sheets, coils/strips, and integrated gutter systems; zinc and ZnAl alloy wire for thermal-spray corrosion protection; zinc anodes for electrogalvanizing; high-purity zinc oxide via the French indirect process; and a complete range of lead oxides (litharge, battery powder, red lead/minium) produced in Barton reactors. It is the only manufacturer in Poland offering the full lead oxide spectrum, and is publicly registered (KRS 0000032784) as part of Grupa Boryszew S.A., one of Poland's largest industrial conglomerates.

Its customer base spans construction (zinc roofing, facades, and gutter systems — e.g., Bank Pekao, Norblin Factory, Gyeonggi-do Library in Korea, DotOffice Kraków), automotive rubber (Goodyear, Continental, Fagumit, Wolbrom, Sumiriko for ZnO compounding), paints and pigments (PPG Industries, Welmot), batteries (Enersys for PbO), and decorative glass/crystal (Lalique, Baccarat). The business model is direct B2B sales through field and inside sales teams at two locations, with dedicated export managers handling markets including South Korea and France, complemented by multilingual technical documentation, free architectural advisory, and certified contractor training programs. Revenue is not publicly disclosed.

ZM SILESIA maintains ISO 9001:2015, ISO 14001:2015, ISO 45001:2018, and ISO 50001:2018 certifications (DAkkS/PCA accredited), a Carbon Footprint certificate (June 2025), and ISCC PLUS certification (2026), underlining compliance credentials relevant to tier-1 industrial and EU construction buyers. Management is led by CEO Dariusz Bednorz, with Robert Hyla as Data Protection Officer; share capital is PLN 56,000,000 fully paid up. The company has no publicly disclosed subsidiaries, no funding rounds, and no M&A activity in the input data, consistent with a mature, parent-anchored industrial operation focused on operational modernization, certification-driven premiumization, and selective international expansion.

Used for thermal-spray (metallization) application of zinc coatings to protect steel elements and structures from corrosion, and for the electrotechnical industry.
• ZnAl Alloy Wire (Drut stopowy ZnAl) Zinc-aluminum alloy wire (ZnAl2, ZnAl4, ZnAl15, ZnAl22) for thermal-spray application of ZnAl coatings. Offers advantages over hot-dip galvanizing including no dimensional limitations, on-site application, repair of damaged coatings, and superior durability. Produced from SHG zinc (99.995% Zn) in diameters 1.2-4.76mm.
• Zinc Oxide (Tlenek cynku) High-purity zinc oxide produced using the indirect French process, where metallic zinc is evaporated at high temperature and oxidized in atmospheric oxygen flow. Characterized by fine crystalline structure, exceptional purity, homogeneous structure, and stable physico-chemical properties. Supplied to the automotive, rubber, paints, pigments, ceramics, and feed-additive industries.
• Lead Oxides (Tlenki ołowiu) Complete range of lead oxides including litharge (yellow gleyt), battery powder, and red lead (minium). Standard oxides are produced using Barton reactors and minium is roasted in a modern energy-efficient furnace.

Expansion highlights5 records

Emerging players

• Penox Group: European producer of lead oxides (litharge, red lead, battery oxides) — directly comparable to ZM Silesia's lead-oxide product line for battery and crystal-glass customers.

Direct peers

• NedZink: Dutch producer of zinc sheet and strip (NedZink NATUREL, NOIR, NOVA) for roofing, facade, and gutter applications — directly comparable product portfolio and target customer base.
• Zochem: North American producer of zinc oxide using the French indirect process — directly comparable to ZM Silesia's zinc-oxide line and competing for the same rubber, tyre, and chemical customers.
• elZinc: Spanish manufacturer of architectural rolled zinc (elZinc Natural, elZinc Slate, elZinc Graphite, Rainbow) — competes with SilesiaZINC across Southern and Eastern European construction projects.
• VMZINC (Umicore): Belgian/French brand of Umicore producing architectural zinc sheet, strips, and rainwater systems — direct head-to-head competitor in European architectural zinc specifications.
• RHEINZINK: German manufacturer of architectural rolled zinc (sheet, strip, coils) and gutter systems — the closest European competitor to ZM Silesia's SilesiaZINC product line, serving the same roofing and facade specification market.

Broad incumbents

• Nyrstar: Global multi-metals business producing zinc and lead — operates smelters and processing facilities that compete in the same zinc and lead input markets ZM Silesia depends on.
• Korea Zinc: World's largest refined zinc and lead producer — broad incumbent that dwarfs ZM Silesia in scale and competes in upstream zinc and lead value chains that ultimately feed downstream architectural and oxide markets.
• Boliden: Swedish zinc and lead miner/smelter with a broad non-ferrous metals portfolio — operates at much larger scale than ZM Silesia in the same zinc and lead value chains.

Regional players

• Huta Cynku Miasteczko Śląskie: Polish zinc smelter (part of Stalprodukt group) — operates in the same Polish non-ferrous metals ecosystem and shares the regional zinc talent pool and supplier base.
