Quarter-turn staircase / half-turn / straight / metal frame
half-turn, quarter-turn, straight
Our straight staircases are staircases made from square metal tubes. This type of stairs are similar to the curved staircases with the difference that these staircases have tubular metal support - square metal tube instead of carcass. That means we use 120x120mm square metal tube for manufacturing the tubular support.
For larger and heavier staircases we use 150x150mm or even larger metal tubes.
