Helicoidal stairs for tanks
TLC tank staircases are specially designed to provide safe and reliable access to industrial tanks of various sizes. They are essential in facilitating maintenance, inspection, and service work for tanks used in different industries such as petrochemicals, food processing, water treatment, and energy. Built with durability and safety in mind, these stairs meet the highest industrial standards and can be customized to the specific requirements of each installation.
Usage
TLC’s helicoidal staircases are suitable for various types of tanks, including:
- Bioenergy tanks: Providing safe and efficient access to bioenergy storage and processing tanks for routine inspections and maintenance of equipment.
- Storage tanks: For large storage tanks, the spiral design allows operators to easily access different levels of the tank while minimizing the footprint of the staircase.
- Chemical and petrochemical tanks: Ensuring compliance with strict safety standards, our staircases provide access to tanks storing hazardous chemicals or petrochemicals.

Advantages of helicoidal Stairs
- Space-efficient design
One of the most significant advantages of helicoidal staircases is their space-saving design. The spiral configuration allows them to wrap around the exterior of the tank, requiring far less ground space compared to traditional straight staircases. This is particularly beneficial for facilities where every square meter of space counts. - Enhanced accessibility
Helicoidal stairs provide continuous, easy access to various levels of the tank. Whether for routine inspections or emergency access, these stairs allow personnel to reach control and measuring instruments without the need for ladders or scaffolding. This is crucial for tanks where frequent access to upper levels is required. - Low maintenance
Helicoidal staircases from TLC are built to last with minimal maintenance required. The materials used are resistant to corrosion, wear, and environmental stressors, ensuring that the staircases retain their structural integrity and safety features over time. This reduces the need for frequent repairs or replacements, saving both time and operational costs for your facility.

Safety Features
At TLC, safety is our top priority. Our helicoidal staircases are equipped with a range of safety features, including:
- Non-slip steps to prevent accidents in wet or hazardous conditions.
- Sturdy handrails designed to provide secure support at all heights.
- Compliance with international safety standards such as PN ISO 14122, ensuring that our staircases meet the highest safety requirements in industrial settings.

TLC design and estimate departments
Our Research and Development team continuously works on enhancing current solutions and developing new ones. TLC also specializes in designing and manufacturing stairs, and steel structures. Our design team emphasizes reducing the need for external brackets, buildings, or additional supports.
The Estimate Department provides prompt responses to client inquiries, offering accurate estimates for project costs and timelines. By considering essential factors like materials, they help clients make well-informed decisions. With their expertise, clients receive comprehensive and reliable project evaluations, allowing for efficient planning. The close collaboration between departments ensures smooth project execution and customer satisfaction from the initial estimate to the project’s completion.
