Comparing Steel Frame Construction to Traditional Building Methods

Choosing the method and materials of construction is a serious matter that can profoundly influence the outcome of a project. There are also many different options to choose from, which can make this decision even more challenging.

Traditional building methods, such as concrete and wood frame construction, have long been the cornerstone of the construction industry, offering tried-and-tested approaches rooted in history and familiarity. However, the rise of steel frame construction has challenged these conventional norms, introducing a modern alternative that promises unparalleled strength, versatility, and efficiency.

In this article, we explore the nuances between steel frame constructions and traditional methods. By considering the advantages and disadvantages of each approach, we hope to make your decision more straightforward and fit your project and your needs.

Different Construction Methods

Framing is an essential part of construction projects, and there are many methods and materials from which to choose. Whether you opt for wood, steel, or concrete, these structures provide the support and stability necessary to ensure the integrity and safety of buildings. It distributes the weight of the building and its occupants evenly to the foundation, preventing collapse or failure.

As you can imagine, different framing materials offer varying degrees of flexibility in design, allowing architects and engineers to create a wide range of structures with diverse shapes, sizes, and configurations. This flexibility enables innovative and creative architectural expressions while meeting functional requirements.

Here are some of the most common materials people can choose from:

Wood Frame

Wood frame construction, also known as timber framing or wood framing, is a traditional method of building structures primarily using wooden components. It involves constructing the frame of a building using a framework of vertical and horizontal wooden members, such as studs, joists, beams, and rafters, which are fastened together with nails, screws, or other connectors. 

These structures primarily utilise lumber as the main building material and typically begin with the erection of a foundation, which can be made of concrete, concrete blocks, or other materials. Once the foundation is in place, the wooden frame is assembled on-site. 

It is important to note that wood frame constructions may be susceptible to moisture damage, rot, insect infestation, and fire if not properly treated or protected.

Steel Frame 

Similar to wood frames, steel frame constructions use steel columns and beams as the primary structural elements. This construction technique has gained popularity due to its strength, durability, and versatility. 

In steel frame construction, the primary load-bearing elements are steel columns and beams. These components are fabricated off-site to precise specifications and then transported to the construction site for assembly.

Like traditional construction methods, steel frame buildings require a foundation to support the structure. Depending on the design and local building codes, foundations can vary from simple pad footings to more complex systems like piles or caissons.

Once the foundation is in place, steel columns and beams are erected and interconnected to form the building's framework. These components are typically bolted or welded together, providing stability and strength to the structure.

Concrete Frame 

As the name suggests, concrete frame constructions use reinforced concrete as the primary structural material. In this construction technique, concrete is poured into moulds or formwork, reinforced with steel reinforcement bars (rebar), and allowed to cure, forming solid structural elements such as columns, beams, slabs, and walls.

This method offers several advantages, including strength, durability, fire resistance, and versatility in design. It is commonly used for a wide range of building types, including high-rise residential and commercial buildings, industrial facilities, bridges, and infrastructure projects. However, it also has limitations, such as the need for skilled labour, longer construction timelines, and potential challenges with formwork and curing in adverse weather conditions. 

Advantages of Steel Frame Constructions

In summary, each construction method has its advantages and considerations depending on factors such as project size, budget, timeline, design requirements, and environmental impact. Steel frame construction offers strengths in strength, durability, speed, and design flexibility, making it a preferred choice for many modern building projects.

Let's compare steel frame to concrete and wood:

Steel vs. Concrete

Here are some things to consider when making the choice between steel and concrete:

Strength and Durability

Steel is stronger than concrete, providing high tensile strength and allowing for longer spans and taller structures. It also offers better resistance to earthquakes and other extreme conditions.

Concrete, on the other hand, is highly durable and offers good compressive strength but lacks the flexibility and ductility of steel. It can crack under tension or seismic forces.

Speed of Construction

Steel frame components are typically fabricated off-site, allowing for faster construction compared to concrete, which requires time for curing.

Construction with concrete can be slower due to the need for formwork, pouring, and curing processes.

Design Flexibility

Steel's strength-to-weight ratio allows for greater design flexibility, enabling architects to create innovative and complex structures with large spans and unique shapes. While concrete offers design flexibility, it may be more challenging and expensive to achieve complex architectural designs compared to steel.

Cost-Effectiveness

Initial construction costs for steel frame buildings may be higher than concrete, but the speed of construction can lead to savings in labour costs and financing expenses over time.

Concrete frame construction can be cost-effective for smaller buildings or projects where long-term durability is a priority.

Sustainability

Steel is highly recyclable, making it an environmentally friendly choice. However, the manufacturing process for steel involves high energy consumption.

Concrete production generates significant carbon emissions, but it offers thermal mass properties that can contribute to energy efficiency in buildings.

Steel vs. Wood 

Here are some things to consider when making the choice between steel and wood:

Strength and Durability

Steel frame construction offers superior strength and durability compared to wood, with better resistance to fire, pests, and moisture.

Wood frame construction is less durable than steel and can be susceptible to fire, rot, and insect damage if not properly treated.

Speed of Construction

Steel frame construction is faster than wood frame construction, with components fabricated off-site and easily assembled on-site.

Wood frame construction can be quick, particularly for smaller buildings, but may require more on-site labour and coordination.

Design Flexibility

Steel offers greater design flexibility, allowing for larger spans and more complex architectural designs compared to wood.

Wood frame construction is limited by the size and strength of available timber, but it can still accommodate a wide range of architectural styles and building types.

Cost-Effectiveness

While steel frame construction may have higher initial costs, it can be more cost-effective over the long term due to reduced maintenance and greater durability.

Wood frame construction is generally less expensive upfront but may require more maintenance and repairs over time, particularly in humid or termite-prone regions.

Sustainability

Steel is recyclable, but its production requires significant energy consumption and carbon emissions.

Wood is a renewable resource and has a lower carbon footprint than steel or concrete. However, concerns about deforestation and forest management practices exist. 

Tips for Steel Frame Constructions

It is clear that steel frame construction is usually the better option when it comes to flexibility, reduced costs, sustainability and, most importantly, speed. Still, the construction process does not end in making this simple decision.
