Design and technical support

TLC’s design department develops carefully planned production solutions, with a focus on optimising project time and costs. Our research and development team helps customers select solutions tailored to their specific requirements.
 
The research and development team continuously improves existing solutions and develops new ones. The design team also focuses on minimising the need for external supports, buildings and brackets.
 
The steps and landings are securely attached to the central column using the innovative TLC method – T-bolts. This assembly system simplifies installation by allowing the bolts to be inserted into specially shaped openings in the column and rotated into position. The infill panels are mounted using spacer connectors.

FAQ

Spiral stairs for tanks are a suitable solution wherever safe access to higher tank levels is required and the available installation space is limited. This type of solution is particularly effective for regular maintenance, inspection and servicing work.

The main advantages of spiral stairs are their compact construction, safe access to the tank roof and durability in industrial environments. Spiral stairs for tanks make it possible to reduce the space required while maintaining the full functionality of the access system.

Spiral stairs can be equipped with anti-slip steps made, among others, of profiled plank grating or welded grating, with slip resistance classes in accordance with DIN 51130. To increase safety, additional handgrips can also be used, including handgrips mounted on the central column or additional internal handgrips, improving ergonomics and control while using the stairs

Spiral stairs take up less space than traditional straight stairs, which is a significant benefit in facilities with limited space. Additionally, they offer better access to high tanks and provide more flexibility in adapting to different configurations.
