Truss Systems Designer - The software allows the design of residential and commercial floors with selected dynamic performance levels, plus concentrated loads from walls, tiled areas, spas, etc. Roof rafters and purlins designed for a full range of wind speeds and roof materials. The software is user friendly and intuitive, and includes a cost comparison analysis for selection of the most cost effective specification for each truss application.
Pryda Frame - Designs virtually any structural timber component and calculates the most cost effective sizes of structural beams, joists, roof members, wall plates and studs. A company specific design program that generates span tables in accordance with input of various parameters.
Multinail - This software has been developed completely in-house since 1980, initially as engineering tools for estimating and detailing, however over the years the focus has changed to incorporate the production of prefabricated trusses from builder’s plans to the manufacturing plant through to the finished product. This has allowed Multinail to develop completely unique software programs that combine to form an exceptionally strong package from estimating and detailing and production management through to controlling automated machinery.
Rothoblaas myProject - A series of intuitive, reliable and free calculation software tools for connections. The incorporate the latest regulations, advanced calculation models and customised reports with illustrations for laying patterns and indications for use of selected products.
