What Protektorwerk Florenz Maisch GmbH & Co. KG does

Protektorwerk Florenz Maisch GmbH & Co. KG is a privately held, family-owned German manufacturer of building profiles and construction components, founded in 1903 and headquartered in Gaggenau, Germany. The company develops, produces, and distributes a broad portfolio of plaster profiles, drywall profiles, steel light construction systems (the Edificio / edi-platform with 12+ modular sub-products), facade systems, thermal insulation composite systems (WDVS), ventilation profiles, roof drainage systems, and construction chemistry products, all positioned as "Made in Germany" with CE marking. Its customer base is horizontal — primarily professional tradespeople (plasterers, drywall builders, general construction craftsmen) across Germany, Austria, Switzerland, and additional European countries — with specialized solutions (Defendo corrosion protection, Silencio sound insulation, Lumino LED lighting, Flexibilo formable profiles, SLP serial renovation window sills) targeting specific use cases such as wet rooms, acoustic environments, serial renovation, and prefabricated housing.

Revenue is generated primarily through one-time sales of physical products via direct field sales with on-site consulting (Vor-Ort-Beratung), national and international sales operations, company-operated distribution warehouses, and a B2B web catalog (Xpress), supplemented by a Loyalty Club for tradespeople retention and the Protektor Akademie for customer education. The company employs 51-100 staff and is led by three Managing Directors (Dr. Christof Maisch, Dr. Jörg Böllhoff, Dr. Andreas Metzger), with no external investors, parent company, or public listing identified. Recent strategic emphasis is on serial renovation (SLP-System), the Edificio steel light construction platform, and the 2026 exclusive European distribution of Bekaert's WIDRA wire corner angles, signaling a deliberate pivot toward higher-value, system-level construction solutions for Germany's industrial-scale renovation and prefabrication markets.

Partnerships

One partnership is on record.

• BekaertcoreChannel Partner/ Reseller/ Distributor · 1 January 2026Protektor became the exclusive European distributor for Bekaert's WIDRA Drahtrichtwinkel (wire corner angles). Bekaert's decision to transfer exclusive European distribution to Protektor was driven by challenging market conditions and a strategic realignment of their distribution structure. The goal is to more effectively tap into existing market potential and strengthen the WIDRA brand long-term. The WIDRA point-welded wire corner angles are used for creating precise, load-bearing edges in interior and exterior plaster applications and are made from galvanized steel, optionally coated or in stainless steel. The product is now exclusively available through Protektor across Europe.

Direct peers

• Saint-Gobain Rigips: Rigips (Saint-Gobain) supplies gypsum-based drywall systems, profiles, and finishing products across the DACH region. It competes head-to-head with Protektor's plaster and drywall profile families for the same plasterer (Stuckateur) and drywall builder (Trockenbauer) buyers.
• Promat (Etex Group): Promat manufactures high-performance building profiles and fire-protection boards for drywall and ceiling systems across Europe. Overlaps with Protektor's Trockenbau specials and Wärmedämmung categories serving commercial and institutional projects.
• Profilsystem Profilati S.p.A. Italian cold-formed steel profile manufacturer for plasterboard and drywall systems, serving the same tradespeople channel across Southern Europe. Comparable product mix (metal studs, edge profiles, finishing trims) to Protektor's Trockenbau and Stahlleichtbau families.
• Knauf Group: Knauf is the largest European maker of plasterboard, drywall systems, and profile assemblies, producing end-to-end framing, fixing, and finishing systems. Directly overlaps Protektor's drywall (Trockenbau) and interior plaster (Innenputz) profile ranges and serves the same professional tradespeople channel.
• PROTEKTOR-Werke competitor: Rigips Profile System / Siniat: Siniat (Etex Group, formerly BPB/Siniat) is a European drywall systems manufacturer offering metal profiles, plasterboards, and finishing systems, comparable to Protektor's commercial offering and customer base.
• Knauf Integral / Knauf Profile Systems: Knauf's profile systems subsidiary makes galvanized steel profiles for drywall and ceiling construction in Europe. Most direct product-for-product competitor to Protektor's standard Trockenbau profiles.

Broad incumbents

• voestalpine Steel Division (Construction): voestalpine supplies cold-formed steel sections and galvanized profiles for the European construction industry. Provides comparable cold-formed steel inputs and prefabricated building components to Protektor's Stahlleichtbau range.
• Gyprock / USG Knauf (USG Boral): USG and USG Boral are global building-products majors in drywall, ceilings, and metal profiles. Larger incumbent operating across a much broader portfolio; overlaps with Protektor on metal framing and trims but with significantly greater scale.
• Tata Steel Construction Systems (formerly Catnic / ComFlor): Tata Steel manufactures structural steel building components, profiles, and floor systems across European markets. Comparable in cold-formed steel framing and structural envelopes to Protektor's ediWall and ediBeam product families.
• ArcelorMittal Construction: ArcelorMittal Construction produces steel building envelopes, profiles, and prefabricated systems for commercial and residential construction. Direct technology competitor in Stahlleichtbau and facade systems (ediWall IF/OS, ediRenoFa), but part of the global steel giant's wider portfolio.
