Widely Accepted Design Software

MemDes® design software is a quick and easy way to design structural steel members that is widely accepted and used by engineers throughout New Zealand. MemDes® enables the user to design standard and customised STELTECH® Welded Beams, as well as imported hot rolled beams where these prove suitable. The fire design module also allows the user to check that the capacity of their beams exceeds the design requirements in fire situations.

MemDes®

MemDes® is a steel member design program written to comply with the New Zealand structural steel design standard, NZS 3404:1997. New Zealand Steel developed this programme for the benefit of New Zealand structural engineers. In 2017 STELTECH® partnered with SESOC to take over the software, to provide ongoing support  and maintenance, and to ensure it remains a useful, relevant and up-to-date tool for its members.
