  • Large-span buildings up to 100 m
  • Versatile structural systems
  • Optimum clear space
  • Reduced number or no interior columns
  • Can accommodate most eave heights and roof slopes
  • Aesthetic profiles
  • Easily facilitates expansions or extensions

    With or without intermediate columns

    Where interior support columns are acceptable, like in vast production or storage areas, our modular building with 2, 3 or 4 modules provides the greatest space at the lowest cost per square meter. With the ability to achieve almost any eave height, this frame allows total flexibility in building width and column locations, and can accommodate interior column spaces.

    The single slope frame design offers a sloping roof in one plane. Clear span, single slope buildings with parallel flange columns are an excellent option when drainage restrictions are an issue. As an example, AP Wing units can, in principle, be attached to all types of buildings, generally using parallel flange columns. It is an economical way of adding to an existing structure. If your building plans call for unobstructed, column-free interior space, our large framing, clear span structure with free spans from 20 to 100 m offers maximum flexibility.

    Just contact our expert team to design the large span structure that matches the size and specifications you need.

Unobstructed floor space to create your ideal workplace layout

Beyond the boundaries

Our large-span buildings create unobstructed, column-free spaces up to 100 metres for a variety of functions. These include activities where visibility and flexibility are important, like for certain types of manufacturing facility, and where large movable objects are housed like aircraft hangars. The Astron structural system enables clear spans up to 100 m.

The use of long span beams results in a range of benefits, including flexible, column-free internal spaces, reduced foundation costs, and reduced steel erection times. Many long span solutions are also well adapted to facilitate the integration of services and industrial activities without increasing the overall floor depth.

Unlimited flexibility

Astron buildings offer virtually unlimited flexibility with the most efficient use of steel. With options ranging from vast to clear span buildings, our building system accommodates a range of building widths, heights and roof slope requirements.

Astron buildings with large spans free of intermediate columns are made of steel. Steel is a material of choice for long span structures due to its high strength, the fact that it is strong and relatively lightweight, and because it is able to extend the farthest without structural support columns.

    The industrial building that best adapts to your needs

    # Ingenious design
    Your project should start long before the construction phase. Our team provides you with different variants of building solutions, considering structural optimization, energy efficiency, natural lighting and minimized construction cost, using 3D models and BIM. Our design & build approach is reinforced by our pragmatic approach based on our experience as engineers, manufacturer and assembler in terms of functionalities and cost control. All Astron products are tailor-made, based on proven pre-engineered solutions worked out within the large group of 150 engineers in 8 European design offices.

    # Evolving the design
    When you start thinking about a new building, you usually have many ideas in your head – dreams, needs, concerns. At Astron we help you to turn your ideas into reality – within a fixed timeframe and a fixed budget. We translate your functional and regulatory requirements into fluid space. You validate each phase and remain the decision-maker for the proposed options: ergonomics, structure, choice of materials.

    # Variable shape
    Adapt your building to any type of environments. Shape, climatic & atmospheric conditions, soil & seismic characteristics, together we will find the best configuration to contribute to the profitability of your project.

    # Future extensions
    Your building can be designed to allow for future modifications to best accompany the development of your company, without interrupting your operations: an extension, photovoltaic installation, future cranes …or mutability.

Energy saving from design to operation

# From A to Z
At Astron we strive to meet all your construction needs with attention to sustainability, providing a simplified and more environmentally friendly way to complete your construction project in every aspect of our business. Astron was one of the first players on the market to provide economical solutions for a «nearly zero-energy building» NZEB for industrial applications.

# Steel promotes sustainability
Because steel building systems start with recycled steel today and can be recycled at the end of their useful lives, systems construction outperforms all other forms of construction for life cycle analysis and least material impact on the environment.

# Certified approach
Astron is assessed by EcoVadis, an international network in the field of sustainability. The assessment focuses on global supply chains, i.e. networks of relationships between production, distribution and procurement. As an example, our optimised use of raw materials and the high recycling rate were rated very positively. The energy optimisation of the Astron buildings and the support of LEED and BREAM certificates were also honoured accordingly. The result is an energy-efficient building that is completed faster, with the highest quality and lowest risks.
