Overview

Carl Spaeter AG, now generally known as Spaeter AG or the Spaeter Gruppe, is a Swiss wholesale company headquartered in Basel. It supplies the construction and construction-adjacent industries with steel, metals, building materials and products used in building services (Haustechnik). The group is organised around three assortment areas: Steel & Metal, Construction, and Building Services. Its parent house is Spaeter AG, which specialises in wholesale, and the group includes five subsidiaries that operate under their own names. In 2005 the group reported sales of more than 500 million Swiss francs with around 700 employees. The company traces its origins to 1901, when it was founded in Basel as a GmbH branch of Carl Spaeter GmbH of Mannheim, a firm connected to the industrialist family of the same name. It became an independent company in 1904 and was converted into a stock corporation in 1913. Its core activity was wholesale of rolled steel products, and over the decades it grew into today's group by adding trading and production businesses. Spaeter serves professional customers across Switzerland, including installers and the construction trade. Its building-services range is described as broad and deep, supported by geographic proximity to customers. In steel and metals, the company draws on long experience and contacts with international steel producers. In construction, it offers a comprehensive range of products and services with nationwide coverage in Switzerland. In recent years Spaeter has invested in digital services and sustainability. It offers e-shops, electronic invoicing, Click & Collect and MyBox pickup options, and has been expanding its photovoltaic capacity, including its largest PV installation at Nänikon. The group continues to operate under the Spaeter name with a structure that includes Spaeter Ticino SA in Ticino and Veuthey & Cie SA in western Switzerland, while RUWA-Drahtschweisswerk AG remains wholly owned.
