Asta metal stairs – adapt the solution to your needs with independent configuration options!

Height and shape of the stairs

Asta modular stairs allow you to adapt access between floors or outdoor entrances to different heights and spatial layouts.

The available stair height starts from just a few steps and reaches up to 4,620 mm. With intermediate landings, the total height can reach up to 6 m.

Dimension range:

height: from 340 mm to 3,800 mm,
length: from 530 mm to 4,620 mm,
from 2 to 19 steps in one set.

Asta stairs are one of the few solutions available on the market that allow the height of the steps themselves to be adjusted, making individual adaptation easier. Special flexible pads adapt to the building’s movement and eliminate the risk of the structure becoming loose over time.

single-flight stairs

two-flight left-turn stairs

two-flight right-turn stairs

three-flight left-turn stairs

The available stair and flight types give you a wide choice depending on the available space and safety requirements.

straight single-flight stairs – the simplest and most compact option,
two-flight stairs with a landing – ideal when the flight length is limited,
three-flight stairs – designed for higher floors and larger spaces.

The flight orientation can change at any point, creating a unique stair layout:

You can choose to mount the stairs directly to the ceiling or wall.
The landing can be mounted on wall brackets fixed to the wall or on posts placed directly on the floor.
Whether you choose wall-mounted or free-standing stairs, you can be sure that the structure will remain stable, safe and adapted to the technical requirements of the building.

Available railing types:

railing without filling

railing with filling

fi 4 mm lines

fi 12 mm tubes

safety railing

A stair railing is not only a safety feature but also an important detail that enhances the visual appearance of the interior. You can choose a simple or more decorative model, adapted to the interior style or to additional safety requirements for children.

You can choose from classic railings, railings with horizontal tubes or cables, and railings with additional infill that are safe for children. All railings are stable and securely attached to the stair structure.

Types of railings:

minimalist (open) – a simple railing without infill, ideal for modern, open spaces. It emphasizes the lightness of the structure and does not overwhelm the interior.
railing with filling – a traditional railing form with horizontal infill. It works well in homes and utility spaces, combining aesthetics with a protective function.
railing fi 4 mm tubes – modern infill made of 4 mm diameter steel cables. Visually discreet and lightweight, yet durable and resistant to stretching – ideal for industrial-style interiors.
railing fi 12 mm tubes – infill made of slim steel tubes with a diameter of 12 mm, creating an elegant and safe arrangement. It works well with both metal and wooden structures.
safety railing – a model designed with the safety of children and pets in mind. Denser infill limits the possibility of slipping through and provides full protection.

Choice of stair tread infill, steps and final colour finish:

welded grid

profiled grid

outdoor non-slip board (latch)

indoor laminated timber (beech)

board base – board

board base – E5 angles

Step infill gives indoor and outdoor stairs their final style and character.
For both outdoor use and home interiors, you can choose industrial metal steps: welded or profiled grating.
Glued beech boards are a great choice for interiors, while an anti-slip board made of protected larch wood is ideal for access to the garden.
Our offer also includes a steel structure that provides an excellent base for your own finish.

We offer a wide choice of colours for railings and treads. You can choose:

hot-dip galvanizing – anti-corrosion protection,
powder coating – 9 colours to choose from the basic palette,
and on request finished in any colour from the RAL palette.
