What Strugal does

Strugal is a privately held Spanish manufacturer of aluminum and PVC building-envelope systems, founded in 1975 and headquartered in Alcalá de Guadaira, Spain. The company designs and produces a comprehensive portfolio spanning casement and sliding window systems (S40 through S160RP series), curtain-wall facades (S52 family), solar protection and awning products (ST1–ST26 series), PVC window systems (ÁVALON, PLANIA, NAZAN sub-brand), interior and exterior aluminum doors, glass railing systems, and built-in wardrobe doors. Core engineering is built around thermal-break aluminum profile technology, in-house extrusion, lacquering, anodizing, and wood-effect finishing, with performance certifications including ISO 9001 and ISO 14001 (held by the NAZAN PVC division) and product-level metrics such as Passivhaus 1.0 thermal transmittance (Uw ≥ 0.9 W/m²K) and acoustic insulation up to Rw ≤ 42 dB.

The company operates through three business segments: Architecture (B2B specifications for architects, developers, constructors, and installers), Industry (bespoke custom aluminum profiles designed collaboratively with industrial clients), and Individuals (B2C finished windows and doors sold through Strugal Stores under a 100% Strugal Guarantee). The go-to-market is enterprise field sales backed by a multi-tier STRUGAL Network — showrooms, delegations, production centers, stores, and a direct commercial team — plus a professional-services layer (COTEC network technical consultancy, BIM modeling catalog, budget software, logistics, and training). Revenue is generated primarily through hardware sales of profile systems to professional customers and finished products to individuals, with quote-based, project-tied pricing across the B2B channel.

Strugal reports more than 1,500 professionals serving 21 countries across Europe, the Americas, and Africa, with deep roots in the Iberian market (delegations across 20 Spanish provinces) and growing presence in Latin America, the Caribbean, and North Africa. The company is privately owned with no disclosed external investors, funding rounds, M&A activity, or leadership changes in the source data.

Products include ÓPTIMA, GALA, VEGA, ILEVA, ARTIS, IRIS for aluminum windows and ÁVALON for PVC windows. 100% Strugal Guarantee on finished products.

Broad incumbents

• Schüco: German global leader in aluminum and PVC window, door and facade systems with deep R&D and a far larger international footprint than Strugal. Comparable technology stack (thermal break, curtain wall) but operates at materially larger scale and broader geographic reach.
• Kawneer: US-based aluminum architectural systems manufacturer (part of Arconic) producing windows, doors, curtain walls and storefronts for commercial construction. Comparable curtain wall and architectural systems offering but operates as a larger North-American incumbent rather than a European regional player.
• Hydro Building Systems: Building systems division of Norwegian aluminum major Norsk Hydro, operating multiple regional aluminum systems brands including Technal, WICONA and SAPA. Comparable aluminum systems technology and integration with primary aluminum production; structurally larger and more diversified than Strugal.

Direct peers
