welcome at TREPEDIA! What is TREPEDIA? Here you find a lot of information about stairs, but focused on German rules and kind of building stairs. Those pages are not translated, sorry.
For you our new stair design software TREPPENPLANER may be the point of interest. TREPPENPLANER is extrem easy to use, gained in practice, for use in practice. And it has a very fair price. Because I’m a mechanical engineer and a locksmith, it is especially made for stairs with steel stringers, residential or industrial.
Unless TREPPENPLANER sounds not very international, it actually runs in German and English.
If you have some questions or wishes, don’t hesitate to contact us!
