CONCEPT STAIRCASE IN UHPC

Stairs play a central role in creating functional buildings and ensuring smooth movement between floors. Our concept staircase combines this essential functionality with elegance and a sleek profile at a highly competitive price. This provides a cost-effective staircase solution that not only meets practical needs but also serves as a striking design element in the building's architecture, without compromising on either quality or durability.

With the concept staircase, we present an entirely new and truly slim staircase design that is far more standardized than the typical custom-made staircases provided by Hi-Con. The concept staircase is also produced in our third generation of Ultra High Performance Concrete (UHPC), CRC i3b.

With a strength range that surpasses traditional concrete types, our UHPC material enables both impressive strength and reduced CO₂ emissions, compared to stairs made from our CRC i2. The clean lines and slim profile of the design reduce the building's weight by approximately 5 tons per floor, which can help reduce the overall load.

Our dedication to innovation is reflected in every curve and step of our stairs. We have developed this staircase solution to be free of complex joints, maintenance-free, and fire-resistant. It is a staircase solution that not only connects floors but also enhances and complements the building’s architecture and structure, creating a sense of openness and space.

"We chose Hi-Con's concept staircase for the Frederiks Plads project because it not only offers a competitive price compared to traditional concrete stairs but also presents a more architectural and sleeker solution. This design is not only aesthetically appealing but also reduces material usage and the amount of concrete, making it a more environmentally friendly choice. Additionally, the staircase meets the high standards we set for quality, design, and constructability in the project."

BENEFITS OF THE CONCEPT STAIRCASE

  • We recognize the importance of price and cost-efficiency in all construction projects. For this reason, we offer our concept staircase at a competitive price while maintaining our high quality standards.

  • Effective and fast delivery is crucial to keeping any construction project on schedule. Therefore, we strive to offer quick delivery times.

     

    To give you an idea of what to expect, the design process usually takes around 10-12 weeks. This is followed by a preparation phase for production, including mold creation, which typically takes 4-6 weeks before manufacturing begins. Our production capacity allows us to manufacture from 1 to several elements per day, depending on the size of the project, the dimensions of the individual elements, and the number of available molds. Typically, we produce one element per day, four days a week.

     

    We place great emphasis on delivering our UHPC elements on time, ensuring an efficient construction process that stays within the planned deadlines. Our goal is to give you the assurance that we are mindful of the importance of precise delivery times.

     

    It’s important to note that delivery times can vary depending on the size of the project and the complexity of the design and elements. Faster timelines may be possible for less complex projects.

  • With an impressive thickness of only 6 cm and step edges of 3 cm, the concept staircases manage to combine minimalist design with maximum strength and durability.

  • We offer a complete solution for your staircase needs. This means that our concept staircases are available in various sizes and railings to complement your project’s requirements and specifications best.

  • The concept staircases are designed with a focus on achieving a slim and elegant profile while minimizing material usage. The slim profile, combined with the strength and density of the material, results in a significant reduction in material consumption compared to traditional concrete staircases.

     

    By producing the concept staircases in UHPC CRC i3b, we also achieve lower CO₂ emissions compared to our CRC i2 material. You can read more about this here.

     

    The material has a lifespan of over 100 years and requires minimal maintenance.

  • Our concept stairs are designed for quick and easy installation, and the UHPC material requires minimal maintenance.

STAIR SOLUTIONS AND DESIGN

At Hi-Con, we understand that stairs are not just functional elements but also play a crucial role in enhancing the aesthetic appeal of a building. With our concept staircase, we offer a solution that combines flexibility in design and installation. We offer a basic staircase ideal for stairwells and emergency exits, while the staircase can also be adapted to function as a visual element in more architecturally demanding environments.


The concept staircase can be adjusted in both height and width, ensuring that each installation is tailored to the project’s requirements and specifications. With color options like gray and light, it easily fits into different design styles.

To further customize the look of the staircase, it can be delivered with different types of railings. This allows for the creation of a staircase solution that not only meets functional requirements but also complements the building’s aesthetics and style. You can explore visualized examples in our gallery section here.

Explore more details about our concept staircases below. Whether you are looking for a simple solution for a budget-focused project or a more striking installation, Hi-Con's concept staircase is designed to meet your needs. We are here to help you realize your project with stairs that are durable, sleek, and beautifully designed.

LESS CEMENT AND MATERIAL CONSUMPTION

The concept staircase is made of Hi-Con’s third generation of Ultra High Performance Concrete, CRC i3b. What characterizes CRC i3b is the use of larger aggregate sizes and a reduced amount of mortar compared to our CRC i2 – and thus less cement. By producing the concept staircases in CRC i3b, we can therefore achieve a lower CO₂ impact compared to our CRC i2 material.


The staircase design is developed with a focus on minimizing material consumption, meaning that the total material usage is significantly reduced compared to traditional concrete stairs. This is made possible by the material’s extraordinary strength, which allows for the production of particularly slim elements. In addition, UHPC has a lifespan of over 100 years and requires no maintenance, resulting in lower lifecycle costs. This long-lasting durability ensures comfort and reduces future maintenance expenses.
