What Sorba does

Sorba Projects bv, founded in 1977 in Winterswijk, Netherlands, is a privately held façade construction specialist that delivers end-to-end engineering, production, and installation services across multiple material types including aluminium, aluminium composite (ACM/SSCM), stainless steel, weathering steel (Corten), glass fibre reinforced concrete (GFRC), ceramic, and copper/bronze. The company operates as a material-independent full-service partner for architects, main contractors, developers, and system suppliers, working across four primary verticals: utility (commercial) construction, residential construction, infrastructure (stations, metro, viaducts), and a 'Specials' line for bespoke art and one-off projects. Its core capability is in-house engineering (approximately 40 engineers) coupled with BIM-compliant modelling, full-scale mock-up testing, and integrated production and surface treatment at the Winterswijk facility, including powder coating, anodising (QUALANOD), galvanising, and patination. \n\nThe business model is project-based professional services: each engagement is custom-engineered and quote-priced, with no standardised price list. Sorba operates three legal entities — Sorba Projects bv (Netherlands), Sorba GmbH (Germany, established 2005), and Sorba UK Limited (United Kingdom, established 1985) — and dispatches its own installers and project managers to international sites. Differentiation rests on regulatory credentials (ISO 9001, ISO 14001, NEN-EN 1090 CE marking, VCA**, CHAS, FIRAS, CWCT), nearly five decades of accumulated reference projects (OV Terminal Arnhem, Sluishuis Amsterdam, Depot Boijmans Van Beuningen, London Elizabeth Line stations, Bernini Tower Rotterdam, THIS Amsterdam, NoordWest Ziekenhuis Alkmaar), and collaboration with architects and engineering firms such as Schmidt Hammer Lassen, Powerhouse Company, Arup, and Koschuch. The company has no disclosed parent, no institutional investors, and no funding rounds on record; it is independently operated under Managing Director Patrick Weijers and Commercial Director Wouter Siedenburg.

Products and services

• Aluminium Facade Cladding Custom-manufactured aluminium facade cladding panels offering durability, modern aesthetics, and a range of colours, finishes, and textures for specific design requirements on commercial, residential, and infrastructure buildings.
• Composite Material (ACM, SSCM) Cladding Aluminium composite panels consisting of two aluminium cover sheets bonded to a mineral polymer core, suitable for refined design in ventilated facades with excellent flatness, formability, bending stiffness, and a wide colour range.
• Glass Fibre Reinforced Concrete (GFRC) Cladding Natural GFRC panels combining concrete benefits with glass fibres, offering a characteristic cloud effect, texture, and colour variation; lightweight compared to traditional concrete with high strength-to-weight ratio for high-rise buildings.
• Stainless Steel Cladding Stainless steel cladding panels crafted for durability and a modern contemporary look, offered in a range of finishes and textures and fully recyclable.
• Weathering Steel (Corten) Cladding Weathering steel cladding with a rust-brown patina providing a warm natural look that acts as a protective layer against further corrosion, featuring self-regulating oxidation and a stable, low-maintenance finish.
• Surface Treatment Services In-house surface treatments including powder coating, anodising, galvanising, patination, and wet painting applied to facade cladding and bespoke metalwork to deliver aesthetics, durability, and finish quality.
• Building-Integrated Photovoltaics (BIPV) Systems Facade application system that seamlessly integrates BIPV solar modules into building envelope designs, collaborating with various BIPV system suppliers to combine energy generation with architectural aesthetics.
• Cassette System Cladding Single-skin metal cladding cassette system combining craftsmanship, durability, and aesthetics, offered in aluminium, steel, and composite material options with various colours, finishes, and textures for a timeless facade look.
• Peripheral Elements for Infrastructure Infrastructure application components for viaducts and bridges including safety barriers, lighting systems, and other peripheral elements that contribute to functionality, safety, and aesthetic appeal of transport infrastructure.

Broad incumbents

• Kingspan Group: Irish global building envelope manufacturer with extensive insulated panel and facade cladding systems. Competes with Sorba in commercial cladding but is far larger and vertically integrated as a manufacturer.
• Centria (a Meridian-branded company): US manufacturer of metal wall systems and architectural facades for commercial and industrial buildings. Partial overlap with Sorba's metal cladding and cassette system offerings, though stronger in North America.
• Schüco International: German global leader in window, door, and facade systems with a much broader product portfolio. Overlaps with Sorba in facade cladding but also competes as a system supplier that Sorba specifies and installs.
• Reynaers Aluminium: Belgian facade and window systems manufacturer and supplier active across Europe. Overlaps with Sorba's aluminium facade offerings but operates more as a systems supplier than a full-service facade contractor.

Direct peers

• Enclos Corp: US-based specialty facade contractor delivering custom curtain walls and complex building envelopes. Comparable as a custom-engineering facade contractor for iconic commercial and infrastructure projects.
• Alukönigstahl: Austrian facade specialist focused on aluminium and glass envelopes for commercial and residential buildings across Central Europe. Comparable full-service facade contractor serving architects and developers.
• Permasteelisa (Permasteelisa Group): Italian-headquartered global leader in curtain walls, facades, and architectural envelopes. Closest large-scale competitor to Sorba in custom facade engineering, production, and installation for commercial and infrastructure projects.
• Rieder Group: Austrian manufacturer of fibre-reinforced concrete (GFRC) facade panels with strong overlap to Sorba's material portfolio. Particularly relevant peer for Sorba's GFRC and concrete-based cladding offerings.
• Seele Group: German specialist in high-end glass and metal facades, known for complex architectural envelopes on landmark buildings. Competes directly with Sorba on premium European commercial projects requiring custom engineering and material expertise.
• Josef Gartner (Gartner): German facade construction company (now part of Permasteelisa) specializing in unitised curtain walls and bespoke metal facades. Direct competitor in the European high-end facade construction market.
