Metallbau Knöpfle

What Metallbau Knöpfle does

Metallbau Knöpfle GmbH is a German family-owned metal fabrication company headquartered in Krumbach-Niederraunau, Bavaria, operating since 1860 with 60 employees across three business divisions. The Bauwesen (Construction) division plans, manufactures, and installs windows, door systems, glass facades, and fire protection structures from metal and glass, serving public institutions, commercial and private builders, and general contractors in southern Germany. The Maschinenbau (Mechanical Engineering) division produces individual components and assemblies for diverse industrial applications using a modern machinery park and current programming systems to process parts from various metallic materials. The Aerospace division, certified to EN/AS 9100, manufactures demanding metal parts in aluminum, steel, and titanium for the aviation industry, providing full-cycle service from raw material procurement through acceptance delegation.

The company operates a direct, project-based sales model with quote-driven pricing tailored to each engagement. Revenue is generated through custom fabrication and installation contracts rather than standardized product offerings, with no publicly disclosed pricing, no recurring subscription or licensing model, and no digital marketplace presence. Customer acquisition is sales-led, relying on regional reputation, the EN/AS 9100 aerospace certification, and direct inquiry via a single contact channel (email and phone) routed through the company website. Distribution is entirely direct, with no intermediaries, resellers, or distributors, and the operating footprint is confined to southern Germany.

The entity is legally registered as Metallbau Knöpfle GmbH at Amtsgericht Memmingen (HRB 4056), represented by family members Manuel Knöpfle and Martin Knöpfle. There is no evidence of external investors, private equity involvement, subsidiaries, or M&A activity. Marketing channels are minimal: the company maintains a single website with basic division overviews and an active job board, but has no visible social media presence, no blog, and no content marketing infrastructure. The firm is a classic Mittelstand operation — privately held, regionally focused, multi-generational, and reliant on quality certifications and skilled labor rather than scale, software, or aggressive commercial expansion as competitive levers.

Core offering

Metallbau Knöpfle GmbH is a metal and glass fabrication company that plans, manufactures, and installs windows, door systems, glass facades, and fire protection constructions for construction clients, while also producing custom components and assemblies for industrial mechanical engineering customers and EN/AS 9100 certified metal parts (aluminum, steel, titanium) for the aerospace industry. The company operates three business divisions from a single site in Krumbach-Niederraunau, Bavaria, serving public institutions, commercial and private builders, general contractors, and industrial customers in southern Germany.

Product overview

Metallbau Knöpfle operates as a medium-sized company with three distinct business divisions: Bauwesen (Construction Services) handles metal and glass building elements such as windows, doors, and facades for various clients; Maschinenbau (Mechanical Engineering) produces components and assemblies for industrial applications using modern machinery; and Aerospace manufactures certified metal parts (aluminum, steel, titanium) for the aviation industry under EN/AS 9100 standards. The three divisions share expertise in metalworking but serve different market sectors.
