Stair Design
Hello Alexander! In this design, we stick with the folded 10mm metal stair and kept the HEB 160 to prevent the stair from sagging. To prevent the stairs from shaking/swaying we use 10mm flat bar which is sandwiched between two 10mm woods. We worked designed based on your pins and plan. We have another entry. Do also check it out. Looking forward to working with you. -Sarah and Cammile
