RAMPA

What RAMPA does

RAMPA GmbH & Co. KG is a privately-held, sixth-generation family-owned German manufacturer of threaded inserts (Muffen / Gewindeeinsätze), headquartered in Büchen, Schleswig-Holstein, and self-described as the worldwide market leader in fastening technology since 1978. The company was founded in 1907 in Hamburg-Bergedorf, originally as a wood-trading and carpentry business; the original "A-Muffe" patent (1910) became the basis for DIN 7965. RAMPA manufactures and sells precision threaded inserts for wood, plastic, metal, and concrete applications, along with complementary fastening products (Einschlagmuttern, Rundmuttern, Quergewindebolzen, Schrauben, Verbindersysteme, Verbindungselemente), insertion tools, and the ETA-approved 1-click lifting element (Hebemittel) for timber construction. The company holds European Technical Assessments (ETA-12/0481 + CE1034 for wood, ETA-23/0542 for concrete), operates a Factory Production Control system under EU CPR 2024/3110 System 2+, and uses cold forming (Kaltverformung) as its primary manufacturing process since 2012. Its most differentiated technology is a patented 30-degree, 3-groove external thread geometry developed in 2018 for the SKD30/SKD330/SKL330 series — the source material describes this as a market-disruptive invention since multi-groove external threads were previously unknown in the threaded-insert category.

RAMPA operates an exclusively B2B model with net pricing (no VAT included), selling primarily through a proprietary e-commerce platform backed by inside-sales teams segmented by customer (Team Holz, Team Kunststoff-Metall, Team Handel). Order processing fees are tiered by order value and channel (e.g., €35 for small phone orders, waived for online orders above €50), and same-day shipping applies for orders placed before 12:00 CET. International distribution is handled through wholly-owned subsidiaries RAMPA Tec Inc. (Canada, 2011) and RAMPA Polska (2012); the company ships to Germany, Austria, the UK, Belgium, France, Poland, the USA, and Canada. Customer segments span the wood-processing and furniture industry (primary), plastic processing, metal processing, concrete construction, and trade/distribution resellers; named use cases include timber construction, stair building, window construction, bridge construction, balcony/canopy anchoring, and fall-protection systems. Value-added services include custom manufacturing (Sonderanfertigungen) with CAD drawings per customer specification, plus climate-neutral (CO₂-compensated) in-house production. The company rebranded from Hans Brügmann GmbH & Co to RAMPA GmbH & Co. KG in 2020, and in 2021 began constructing a new KfW40 energy-efficient headquarters in Büchen that will consolidate all departments including production.
