DIY steel frame stairs 

I used a 80x160x6mm square tube for stair ride and 120x8mm flat bar to hold the steps

Thanks for sharing ! It’s amazing !

Thanks. In what kind of format do you need the model file? Stl or F360 or any other? And I need your mail address.

Thank you, and of course. Send me your e-mail.
