    Using a portal frame structure is a common construction technique, providing the industrial and commercial sectors with wide-span, low-rise buildings commonly used for warehouses, retail premises, or agricultural barns. Steel, being a cost-effective and durable material, is commonly used for the production of structural steel portal frame buildings. As steel specialists, Bromsgrove Steel closely follows project specifications to produce quality steel members and components for portal frame buildings, meeting client expectations every time.

    From portal frame house construction to larger-scale industrial buildings, we have experience working on buildings of all shapes and sizes.

    What are the advantages of a portal frame?

    The construction of structural steel portal frames is quick and relatively simple; they can be fabricated off-site to further speed up the construction process. Portal frame builds are moreover cost-effective, with reduced manual labour costs and minimal material needed. The wide, open, and weatherproof space provided by the building can be used for a variety of activities across many industries.

    What are the types of portal frame structures?

    Portal frames can be constructed in several forms to meet your building requirements. For instance, common frame types for the portal frame include:

    • Pitched roof portal frame: this is the most common type of portal frame, featuring a symmetrically pitched roof. It is also called a single span and can include mezzanine flooring.
    • Mono-pitch portal frame: this frame features a single sloping roof, rather than a pitched roof, and has a smaller span.
    • Multi-span frame: the extended span of a multi-span frame will often require one or more vertical support columns.
    • Curved rafters can also be used for architectural expression on portal frames, though this is less common.

    How far can a portal frame span?

    The span of a portal frame will depend on your choice of steel frame structure. However, a standard design of portal frame buildings spans the roof frame between 20 and 35 meters. Multi-span frames can safely span wider lengths than this.

    How much do steel portal frame buildings cost?

    The cost of steel portal frame buildings can vary depending on a range of factors. These factors include the size of the building, the complexity of its design, the type of steel used, and any additional features that are included. When determining the cost per square foot, considerations such as the overall square footage and the intricacy of the design are taken into account. The type of steel, including the specific grades and finishes, can also impact the overall cost.

    In addition to these factors, other elements to consider include insulation, cladding, finishes, foundation requirements, structural elements, and the inclusion of doors, windows, or mezzanine floors. All of these factors contribute to the final cost of the building.
