In brief, Ecojoists™ is a modern and efficient open web joist system which is being adopted widely by housebuilders and commercial property developers across the UK. Ecocoists™ consist of parallel stress timber flanges joined with engineered V-shaped steel webs with nailplated zones from Gang-Nail™. The result is an easy to install system, and with its open web design, enables fast fixing of plumbing and electrical infastructure.
The metal web system was originally devised by Truswal Systems in 1976 and is widely used throughout the USA.

Truswal introduced the system to the UK in the 1980's. The system has now been adopted by many major building developers across the UK and has been acclaimed as a quality product throughout the industry, offering huge advantages over other floor joist systems. The system is now widely used in housing and commercial developments.

In 1999 Robinson Manufacturing helped to pioneer the manufacture of Ecojoist™ in the UK as a joint project with Gang-Nail™ Systems, and is now the UK's largest manufacturer of Ecojoists™.

Robinson Manufacturing continue to work closely with Gang-Nail™, who operate under an exclusive licence arrangement with Truswal Systems, to develop product innovations for the construction industry.
