Selecting the appropriate steel frame system is one of the most critical decisions in any construction project. Steel framing construction provides a flexible solution for many architects, designers and construction workers on site, consisting of a series of vertical universal columns and horizontal universal beams, riveted, bolted or welded together to form a hollow shape. With proper planning and expert guidance from structural steel estimating specialists, you can ensure your project benefits from the strength, durability, and cost-effectiveness that steel construction offers.
The importance of making the right choice cannot be overstated, as the structural framework forms the backbone of your entire building and influences every other element from foundations to cladding systems. However, with multiple steel framing options available from traditional portal frames to modern light gauge steel systems, understanding the specific requirements of your project and selecting the most appropriate solution requires expert knowledge of structural engineering principles, UK building regulations, and current market conditions.
Steel frame systems have revolutionised the construction industry by offering superior structural performance compared to traditional building methods. The construction industry has seen a sharp increase in the application of cold-rolled steel sections and lightweight steel framing systems in modern construction in recent years, set to increase as new technologies begin to supersede the more traditional building methods to meet increasing demand for greater innovation, higher build regulations and superior performance specifications.
Understanding the different types of steel framing systems available is essential for making an informed decision. Steel structures are formed from a skeleton frame that consist of vertical columns, horizontal beams and so on made from steel materials, riveted, welded or bolted together, often in a rectilinear grid, typically used for medium and high-rise, industrial, warehouse and residential buildings. These systems provide exceptional advantages including resilience to earthquakes and wind loading, ease of construction and deconstruction, short construction time, and high ratios of strength to weight.
The purpose of your building significantly influences the type of steel frame system you'll need. Industrial buildings typically require different specifications, with low eaves buildings (4m to 8m high) requiring around 30-40kg per m² GIFA including fittings, while high eaves buildings (10m to 13m high) usually require around 40-50kg per m². Commercial projects such as office buildings, retail spaces, and mixed-use developments often benefit from skeleton frame systems that allow for flexible internal layouts and future modifications.
Residential developments, particularly multi-storey apartment buildings, may require different considerations including fire resistance, acoustic performance, and integration with other building systems. Industrial applications such as warehouses, manufacturing facilities, and distribution centres typically favour portal frame systems due to their ability to provide large clear spans without internal columns.
Understanding your building's structural requirements is crucial for selecting the appropriate steel frame system. Factors such as live loads, dead loads, wind loads, and seismic considerations all influence the design requirements. Steel structures offer resilience to earthquakes and wind loading, ease of construction and deconstruction, short construction time, and resistance to fire when treated.
Professional structural steel estimating services can help determine the exact specifications needed for your project. Expert quantity surveyors and steel detailing specialists can assess your architectural plans to provide accurate feasibility assessments and ensure your chosen system meets all building regulations and performance requirements.
Site-specific factors play a significant role in determining the most suitable steel frame system. Urban construction sites often present challenges such as limited access, confined spaces, and proximity to existing structures. City centre buildings are generally constructed on existing confined or irregular sites, which influence the building form and is likely to prevent the use of a regular column grid and may result in alterations to floor plates on the upper storeys.
Ground conditions, including soil bearing capacity and the need for deep foundations, can affect both the choice of frame system and overall project costs. Coastal locations may require additional consideration for corrosion protection, whilst areas prone to high winds or seismic activity need enhanced structural design.
Cost is invariably a crucial factor in selecting the right steel frame system for your building project. On average, steel frame building prices will range between £250-£350 per m², covering the cost for a specialist to erect the frame with cladding but excluding the cost of groundwork. However, these costs can vary significantly based on project complexity, location, and current market conditions.
Steel prices fluctuate considerably due to market volatility, making accurate cost estimation essential for project planning. The rising demand for structural steel has seen the average price hit around £1,300 per ton, with the most important factors affecting steel frame building prices being location, design and size, and material costs. Professional estimating services can provide current market pricing and help optimise your design for cost-effectiveness.
Portal frame construction dominates the industrial sector due to its efficiency and cost-effectiveness. Standard steel portal frame construction dominates the industrial sector, with steel frames accounting for 98.3% of all industrial shed building construction in the UK in 2024. These systems comprise columns and rafters with localised haunches at the eaves and apex, creating very efficient structures that can accommodate large spans.
Portal frames are particularly suitable for single-storey buildings requiring large clear spans such as warehouses, sports halls, and manufacturing facilities. They can efficiently deliver spans from 25m to 40m with standard spacings between frames of 6m to 10m, typically 8m. The building envelope provides restraint to the structural steelwork, resulting in exceptional structural efficiency.
Skeleton steel framing systems offer exceptional flexibility for multi-storey construction and complex building layouts. Universal steel beams and columns provide excellent support, with connections achieved through bolts or welding procedures. The distance between columns can be adjusted based on project requirements, providing design freedom for floor and roof layouts.
These systems are ideal for office buildings, hotels, residential towers, and mixed-use developments where flexibility in internal arrangements is essential. They also accommodate services integration and future modifications more easily than many alternative construction methods.
Light gauge steel framing systems allow you to complete projects faster and cheaper than ever before, with houses built using this technology being very quick to construct, improving efficiency, minimising waste and even leading to early project completions. LGSF systems use cold-rolled steel sections that are lighter than alternative building materials, making transportation and handling more efficient.
These systems are manufactured in controlled factory environments to specific project requirements, allowing quality checks to be carried out more efficiently and reducing the likelihood of on-site issues. LGSF is particularly suitable for residential construction, modular buildings, and commercial applications where speed of construction is paramount.
Proper structural engineering is fundamental to successful steel frame system selection. Professional structural engineers must calculate dead loads, live loads, wind loads, and seismic forces to determine appropriate section sizes and connection details. High rise construction (10-15 storeys) often requires longer structural grid spans to achieve more open space in lettable floor areas, increasing the weight of the steel frame, typically 75-90kg/m² including fittings.
Cellular beams may be adopted in commercial buildings to maximise floor-to-ceiling heights and increase flexibility for building fit-out, with openings through the web for services distribution. Transfer structures may be required in mixed-use schemes to accommodate different grid requirements between commercial and residential areas.
Steel frame systems must comply with building regulations regarding fire resistance, with appropriate fire protection applied where required. Steel offers resistance to fire when treated, and can be used in combination with other types of construction. Modern steel frame buildings can achieve excellent fire ratings through the use of intumescent coatings, concrete encasement, or board protection systems.
Building regulations also specify requirements for thermal performance, acoustic insulation, and structural safety factors. Professional quantity surveyors and building regulations specialists can ensure your chosen system meets all applicable standards whilst optimising for cost and performance.
Modern steel frame systems must accommodate increasingly complex building services including mechanical ventilation, electrical systems, telecommunications, and renewable energy installations. Steel framing systems allow space for additional insulation, providing enhanced thermal or acoustic insulation within buildings, with components that can be custom-made according to project needs.
Coordination between structural and services engineers is essential to ensure adequate provision for services routing whilst maintaining structural integrity. BIM (Building Information Modelling) and 3D modelling technologies can help visualise and coordinate these complex interactions during the design phase.
Accurate cost planning is essential for successful project delivery, with steel frame costs typically representing a significant portion of the overall construction budget. Where initial budget estimates of steel frame costs are not realistic, the wrong frame solution can be selected at a higher cost of not only the frame but potentially also the related building elements, affecting buildability, logistics and the construction programme.
Professional estimating services provide detailed cost breakdowns including material costs, fabrication, transportation, and erection. These services can also identify value engineering opportunities to optimise costs whilst maintaining structural performance and architectural requirements.
Steel prices are subject to global market fluctuations, making professional cost advice essential for accurate budget planning.
