CSB Industrial Building Features
Are you considering steel portal frame buildings for your project? Known for their structural integrity and economic benefits, these buildings are crucial in industries where durability meets design. Our article cuts through the complexities, offering you a comprehensive understanding of their advantages, typical applications, and cost-efficiency – critical knowledge for anyone evaluating the suitability of cold-rolled steel portal frames for their construction initiatives.
Key Takeaways
- Steel portal frame buildings are a dominant choice in the UK construction market, particularly in industrial and agricultural sectors, due to their cost-effectiveness, bespoke sizing, fast assembly, and long-term durability.
- These buildings offer structural benefits, including lightweight design, which reduces foundation costs, rapid and economical delivery and construction, and resistance to corrosion, pests, and extreme weather, enhancing their resilience and longevity.
- Customers are provided financial security through CSB’s Bank Bond system with Nat West and the option to inspect buildings pre-purchase, ensuring compliance with regulations and client satisfaction.
Introducing the Architectural Marvel
With their robust construction and sleek design, steel-framed buildings embody strength and efficiency in new steel building technology. Promising superior strength, these pitched buildings boast lighter, more robust structural components than traditional weight-bearing wood or concrete products. Their cost-effectiveness extends beyond initial pricing, thanks to compact steel bundles that streamline transportation to the building site for steel buildings.
Bespoke sizing and bolted connections, which eliminate the need for onsite welding, contribute to the swift assembly process. Ongoing value and durability are ensured by long-term guarantees on cladding finishes, which can last up to 30 years, depending on the build location. These are bold claims indeed. But do they hold up in the face of scrutiny? Let’s examine these claims further.
Targeting the Market
Dominating the industrial sector, steel portal frame buildings hold a market share of 98.7% in the UK’s industrial shed building construction. They find extensive use in various applications in the agricultural sector, including livestock sheds, grain storage, and equipment housing. These buildings serve diverse purposes beyond the industrial and agricultural sectors, including offices, factories, schools, public buildings, and residential applications.
The construction process is streamlined by off-site fabrication of steel components and minimal onsite labour requirements. Steel portal frame buildings emerge as the preferred solution for projects with tight deadlines or subjected to weather constraints. Agricultural businesses also benefit from post-construction support and promotional opportunities offered by suppliers.
Assembly Made Simple
Famed for their rapid assembly time, steel portal frames allow entire structures to be erected in mere weeks, thanks to the integration of prefabricated components and a swift installation process.
The portal frames of cold-rolled steel structures are composed of two main components: columns and rafters, which are connected to form a sturdy skeleton. Secondary elements like purlins add support to the building’s envelope. Cladding is applied to walls and the roof for aesthetics and to provide essential thermal and acoustic insulation. This reinforces the structure’s overall integrity by transferring loads to the carrying framework.
A successful assembly process hinges on precise pre-measurement of elements because there’s limited scope for adjustments once components are onsite. Therefore, accurate sizing and preparation are essential to avert construction delays. 1st Choice can help with an installation service.
Structural Elegance and Efficiency
Steel-framed buildings are engineered to combine timeless design with robust portal frame construction, offering both sophistication and structural excellence. Main portal frames, including mansard portal frame options, are generally made from UB sections with substantial eaves haunches to increase moment resistance and add stiffness, contributing to the structural elegance and efficiency of the portal frame building.
Steel portal frames offer several advantages in construction:
- They are lightweight, which reduces foundation size and substructure costs.
- They can be delivered quickly, saving time on construction projects.
- They have lower substructure costs than other materials like precast concrete and load-bearing masonry.
- They are economical for modern construction, especially on urban sites with substantial foundation and substructure costs.
Built to Last
Steel portal frame buildings employ pre-galvanised cold rolled section frames made from high tensile materials and Plastisol-coated steel sheets for roofing and walls to enhance durability and resist corrosion. Galvanised steel, with its hot zinc coating and additional powder treatments, provides a robust defence against rust and weathering, contributing to the long-term resilience of the structure. Insulated panels can also be used in the construction process to improve energy efficiency.
Structural steel components, often used in structural steelwork, offer several advantages over wooden frameworks:
- They are immune to the damaging effects of burrowing insects and mammals.
- Steel framed buildings use S355 steel sections for structural integrity.
- They often include rainwater systems due to their robust and maintenance-free qualities.
User-Friendly by Design
Featuring industrial roller doors with durable galvanised laths and electric motors, steel portal frame buildings provide secure and convenient access. Multi-point locking steel personnel doors with customisable colours offer secure, user-friendly access points.
Various design options cater to specific user needs, including the choice of the number of doors, windows, and structure size. Users can personalise their space with interior finishes, such as luxury vinyl flooring and external cladding.
Large clear internal spans accommodate a variety of uses, offering flexible space without compromising design.
Real-World Resilience
With high resistance to pests, insects, moisture, and adverse weather conditions, a steel portal frame building is well-suited for various climatic zones and lowers potential maintenance costs. The design of these buildings considers a spectrum of forces, such as permanent loads, service loads, and variable actions like snow, wind, and roof loads, ensuring structural resilience.
Steel-framed building construction offers several benefits, including:
- Fire resistance, which is critical for businesses aiming to minimise fire risk
- Thermal comfort throughout the year, adapting well to seasonal temperature changes
- Insulated walls and roof, providing additional energy efficiency
These features make steel frame construction a popular choice for many businesses.
Additionally, operational carbon emissions from these buildings are competitively low, indicating a sustainable choice for environmentally conscious businesses.
The cladding of a portal frame building plays a structural role, transferring loads and restraining the purlins or side rails, simplifying maintenance efforts over the building’s lifespan.
The Bottom Line
The cost of framed buildings, influenced by structural height, ranges between £108 and £142 per m2 for buildings with low eaves and £132 to £169 per m2 for those with high eaves as a very ‘ballpark’ guideline.
Alternative construction methods to cold rolled steel portal frames include Precast concrete, trusses and space frames
These methods can be used for industrial buildings. However, it is essential to note that precast concrete and glulam beam structures can have a higher cost, with a reported 12% cost premium for a warehouse and 2.4% for a supermarket compared to steel portal frames. Additionally, construction times may vary depending on the chosen method.
Trusses and space frames are used for long spans but may not be as cost-efficient as steel portal frames. Operational carbon emissions of a building are minimally impacted by the frame material choice, suggesting that from a sustainability perspective, steel portal frames are comparable to other materials like glulam.
Furthermore, steel portal framed buildings have a lower embodied carbon impact than alternatives like precast concrete and glulam framed structures, reinforcing their sustainability profile.
