trappsteg

Trappsteg is a Swedish term that translates to "stair step" and refers to a single step within a staircase. The word is used in architecture, construction, and interior design.

In a staircase, a trappsteg traditionally comprises a horizontal tread and a vertical riser. Some designs also emphasize the nosing, the rounded edge of the tread, for grip and visibility.

Dimensional standards for trappsteg vary by country and building code. Typical ranges include risers of about 150–190 mm and treads of about 250–320 mm, with allowances for headroom, width, and handrails.

Materials and finishes for trappsteg range from timber and laminated wood to concrete, steel, or stone. Finishes may be stained, painted, or left in natural texture, depending on aesthetics and durability requirements.

Construction methods vary: steps can be manufactured as prefabricated units or built in situ. They are anchored to stringers and paired with balustrades or railings for safety and support.

Safety and accessibility considerations emphasize slip resistance, adequate lighting, uniform riser height, and secure handrails. Regulations often require non-slip surfaces and clear width appropriate for intended occupancy.

Historically, trappsteg reflect architectural styles and building technology across periods. Today, they are a common feature in homes, offices, and public buildings, available in numerous materials and configurations to fit design goals.
