Software for analysis and design of steel structures

INSTANT steel is a reliable and effective structural software solution for a wide range of steelwork which can be simulated with linear beam elements such as: industrial buildings, pylons, trusses, pipe racks, bridges, multi-storey buildings, hangars, canopies and stairs. It is distributed to the European market since 1995 and has been used in thousands of steel projects.

INSTANT steel can analyse and design almost every type of structural beam is used in modern steel industry, including special profiles such as tapered, castellated, and cold rolled sections. It includes a complete connections design environment (EC3 Connections).


More than 500 design offices and steel fabricators have chosen INSTANT steel for its flexibility in model simulation, reliable output results, and consistency on the application of the Eurocodes.

INSTANT steel is being developed by Conception Consulting Engineering Solutions (CCES). It is one of the first structural software applications released in Europe which incorporated Eurocode 3 design and it is recognized as a reference program for the analysis and design of steel structures.

INSTANT steel is continuously updated with new features so as to comply with the increasing demands of the steel industry.
