Rintal Gamia Metal Black Spiral Staircase Steps Anti Slip Strips Closeup

A Steel Stair for a Working Loft

Ladders and pull-down stairs are fine for a once-a-year attic, but a loft you use every week needs a stair you can climb with your hands full. The Gamia Metal is a modular spiral in painted steel with the steps welded to the spacers, anti-slip strips on every tread, and a rise you set between 8¼" and 9" during installation to hit your exact floor-to-floor height. The 47" kit weighs 337 lb boxed, a number that says how much steel is in it. A matte, scratch-proof epoxy powder coating keeps the silver-gray or black finish intact through years of daily use.

Rintal Gamia Metal Silver Gray Spiral Staircase With A Woman Climbing In A Living Room

Turn a Loft Into a Room You Use Every Day

Steel Spiral, Three Diameters

The Garage Mezzanine Builder — Built a storage deck over the bay, and a ladder was never going to work for weekly trips with bins.

The Loft Converter — Finishing the space over the workshop and needs a stair that fits where a straight run would eat the room below.

The Parts-Loft Shop Owner — Climbs a dozen times a day with hands full and wants steel treads that don't flex.

The Barndominium Builder — Open-plan steel building, and a steel spiral matches the structure without a carpentry sub.
