System members develop and support Software to design nail plated roof trusses as well as supply the specified nail plates and joiners. The System members Software must be independently verified by ITC-SA recognised experts in the field that are also ECSA registered Engineers in the Civil Engineering discipline to ensure that the System’s software generates designs that are fully compliant with all relevant Standards and Regulations.

The System members contract with the ITC-SA to ensure that specified minimum Engineering and other technical support is provided to any Fabricators that they may licence with their software. This helps to ensures that specified minimum technical standards are met by all ITC-SA Fabricator members. This assists Professional Engineers in assessing rational designs of roofs erected by ITC-SA Fabricator members
