Carla stairs are a modern and practical solution for the industrial sector. They belong to the group of modular stairs, which makes them different from the well-known classic design stairs. Our engineers have managed to create modular spiral staircase, which allows to omit time- and capital-consuming process of preparation of technical documentation. Thanks to a wide range of variants the spiral staircases can be easily adjusted to the customer’s needs, which guarantees time saving during the realisation of the order.

The main advantage of the industrial spiral staircases is the possibility to maximise the available space in rooms with limited space. They find their application e.g. in logistics, storage or production halls.

Due to their construction and intended use, the TLC company offers three types of modular stairs:

What are ready-made modular staircases for industry?

A ready-made modular staircase is nothing else than a communication link between floors of a building. As the name suggests, they consist of ready-made elements/modules which significantly facilitate their installation. The Carla industrial staircase system is designed for self-assembly. The customer therefore does not need a team of professionals – the whole process is based on the enclosed instruction. In addition, when using the spiral staircase, full use of space is ensured.

External and internal modular stairs - intended use

The Carla spiral staircase system was created with the industrial sector in mind.

The simplicity and lightness of construction combined with a guarantee of safety makes the TLC steel staircase ideal for the communication function in industrial buildings. In addition, they can also provide external access to the property. Their spiral construction is a deliberate effort to facilitate the use of space which is often very limited.

The Carla system can be used as:

  • Stairs in warehouse areas
  • Stairs in production halls
  • Stairs in logistics halls
  • Stairs in machine parks
  • Stairs in factories
  • Stairs as entrances to mezzanines
  • Stairs in cold stores
  • Stairs in waste sorting plants
  • Stairs in hangars
  • Stairs in technical premises
  • Stairs in public places

In addition to industry, the spiral system can also be used in the agricultural sector.

How to install a modular staircase. The Carla industrial staircase system

Installation, is often one of the main factors affecting the attractiveness of a product. It is challenging to create a product that is safe and easy to install. In the case of the Carla spiral staircase we offer the assembly of the steps to the central column based on the innovative TLC method – hammer bolts.

In the industrial spiral staircase system we have a choice of three platform assembly options:

  • Straight ahead
  • To the right or left
  • Assembly without platform

It is possible to extend the platform with additional elements. We provide both the external and internal metal stairs with step height adjustment from 160 mm to 200 mm. Due to the industrial character of the stairs the filling of the steps is available in two options:

  • Profiled grating
  • Welded grating

Profiled grating

Both fillings have been developed in accordance with TLC standards. They provide anti-slip protection for the user.

In addition, the Carla industrial staircase has the option of fitting an internal handrail and a casing made of welded grating. Equipped with a modular handrail, the Carla system complies with the highest safety standards (product complies with EN ISO 14122-3) while maintaining user comfort. *

Modular staircases for industry – why us?

We have been working with steel for years and only use high quality materials, which ensures the durability and resistance of our products. In addition, our steel stairs (both straight and spiral stairs) are hot-dip galvanised. This provides permanent protection against corrosion, which guarantees the possibility of using the system both as external stairs and internal ones.

As a world leader in the industry, when creating the Carla industrial staircase system, our goal was to improve the quality of communication within a building’s floors, while reducing time and investment costs. Amidst a wave of complex innovations, we have prioritised simplicity and ease of application.
