5 Benefits of Using Steel Framing in Modular Construction

The worldwide trend continues to shift towards using offsite construction and modular building methods.   
We examine 5 key reasons why steel framing also known as cold formed steel (CFS) and light gauge steel (LGS) is fast becoming the preferred material of choice over timber in modular manufacturing.   

You can find more information on our web, so please take a look.


1. Lightweight

Steel is lighter than timber. The benefits of this fact alone have a huge impact on the manufacturer when it comes to lifting and transporting steel framing.  A structure made of timber can be up to 3 times heavier than the same structure made from cold formed steel.  

2. Less Storage Capacity

Timber is often required in a variety of profiles and multiple lengths which can be harder to manage and can take up a larger amount of storage space.  In comparison light gauge steel has one profile and the stock comes in the form of steel coils. These coils are 700-900 meters in length and are compact taking up very little space.

3. Less Waste

Steel coils are used until they are empty and they produce very little waste, with only a small amount where the tooling has been specified and at the end of each coil.  This waste can also be recycled.

Fixed lengths of timber need to be cut to the correct size.  Due to the process in which this is done, often they are cut too short and are thrown away as they are unable to be used or recycled.  

4. Modular Construction Timelines

The process of manufacturing using timber is fairly manual resulting in more risk of human error and longer build times. Where constructing using cold formed steel requires less skilled labor to build and install the steel framing which further accelerates the whole process.

5. Precision and Accuracy

The design-led process of producing cold formed steel framing is extremely precise which makes it highly accurate and more efficient.  The repetitive nature makes it a more cost-effective and faster solution.

There are software plugins available with the FRAMECAD system for the most commonly used BIM and modular packages that customers may already be using. This makes the FRAMECAD solution even more advantageous over its competitors.


In Summary

Using steel framing in modular construction has many benefits which include speed, precision and accuracy.  It’s lightweight, produces less waste and takes up less storage space than wood.  All of which give a better return on investment than using more traditional methods.

Modular Construction: 7 Benefits of Steel Frame Homes - Easy Render

For a long time, builders have used solid wood to construct modular house frames and substructures. Today, other options are available, such as mass wood, concrete, and steel. With the introduction of CAD/CAM technology, using steel has become quite straightforward. Opting for a steel-frame house instead of a traditional wood-frame system will allow you to enjoy the following benefits:

1. Increased Efficiency

You'll save both time and money with steel modular homes. That is because these building components can be ordered from suppliers to the precise size and dimensions specified in the CAD designs. This contributes to a simple and faster installation process.

The subframe could be assembled in a few days, depending on the building's sizeF and complexity. Plates and gussets are made to order, including connecting holes. The frames arrive supported and completely straight, allowing for easy wall installation. In contrast to timber frames, no further preparation is necessary prior to plastering.

On average, a basic frame consisting of five modules takes around seven days to construct. That said, the faster building and installation period results in lower initial costs.

Long-term cost savings are another benefit. This material is more durable by nature, resists rust and corrosion better, and is impervious to termites and wood rot. It also has the added advantage of being easy to modify if the structure needs to be expanded or changed over the course of its lifetime.

That said, older steel-framed modular structures can be taken apart from their bare frames and given new life using modern building supplies and technology.

With custom metal fabrication, these aging steel-framed modular structures can undergo a remarkable transformation. Custom metal fabrication enables the revitalization of these structures by incorporating innovative design elements, improved structural integrity, and enhanced energy efficiency.

2. Variety of Designs

One of the main critiques early modular construction faced was that modular buildings seemed like boxes. Steel's strength, malleability, and durability have made it possible for designers to produce previously difficult features like cantilevered modules, rounded corners, and pitched roofs. These features enhance the building's aesthetic appeal and can hide its modular construction method.

The frame's strength allows designers to create bigger open spans for a more modern, open design. Plus, a steel frame house is a great option for tough locations with steep grades. Its rigidity and strength also make it capable of supporting modern multi-story modular constructions.

3. Safety

Compared to traditional lumber, this type of construction is a lot safer. It integrates into building designs as a fully developed, distinctly verifiable system and offers a significantly higher level of fire resistance.

Welded connections can be easily tested and certified using non-destructive methods, and they are inherently stronger than wood connectors. You may anticipate a structure with true structural integrity when using this kind of frame.

4. Quality

There is no question that a modular house built with a metal frame results in a high-quality product.

Steel frames are made with a high tolerance for straightness and dimensional correctness. Most respectable manufacturers and suppliers can track and certify these qualities. The material's durability assures that all components utilised in the fabrication of modular structures will not fail during shipping and installation.

This metal is naturally corrosion-resistant. Its performance is predictable and dependable in both indoor and outdoor building conditions. This eliminates any doubt regarding the building's performance during its lifetime. Steel can be protected in severely corrosive conditions by hot-dip galvanizing or the use of other appropriate coatings.

Welded steel connections are not only stronger than other materials but they can also be easily inspected to ensure that they conform to the specified designs and standards. Bolted connections utilised in steel fabrications are intended to ensure their strength and adaptability for any modular building application. Bolts and fasteners acquired from reliable vendors will be supported by quality assurance procedures that ensure their performance when used as indicated.

5. Sustainability

Steel is an excellent material choice for the environment as well as the industry. Modular steel buildings are expertly crafted. As a result, there is very little material lost during building and landfill waste is significantly reduced.

This metal is also completely recyclable. All components of the structure may be dismantled and recycled for use in other modular constructions or fabrications at the end of a building's life.

The environmental impact of this type of construction is negligible. Because the modular structures are prefabricated, there are no dangers to nearby communities from dust, spills, pollution, excessive noise, or disruption.

6. Lower Cost

Timber and steel are generally priced equally, and while there are numerous factors that influence material pricing (volume discounts and design requirements, for example), like-for-like frame cost differentials are almost certainly identical.

There is no effect on the cost of building permits, though, because building permits are decided by the cost of the construction, not the materials utilised.

However, steel has certain pricing benefits over wood that may assist achieve more profitable projects:

  • This modular house is considerably quicker to build, hence labour expenses are lowered.
  • The greater precision of light-gauge steel frame manufacturing implies fewer rework, call-backs, and waste, all of which affect final prices.
  • This type of frame holds up over time while remaining straight and true. This suggests that plaster linings and other fixtures and fittings will likely crack less frequently over time, reducing the cost of ownership.

7. Resistance to Moisture

Steel is more resistant to mould and can withstand water damage than wood. Rust resistance is also improved by galvanized steel or zinc coating treatments. Once you decide that a such a modular home is the right option for you, it will be time to find a reliable modular home builder to work with.

What to Consider When Looking for a Builder

When looking for a builder, look for one with a thorough résumé and decades of experience so you can be sure of their ability and talents. You'll find builders that specialise in other types of building offering to build modular homes as a side option. Make sure you avoid them.

Even if it's an attractive offer, these contractors are likely unfamiliar with the numerous building procedures unique to modular construction. When it comes to modular house construction, there are several processes involved in the manufacturing and construction process. It's critical to deal with builders who aren't simply acquainted with the construction process; they must also be ready to take the time to walk you through it, step by step, so you feel confident in their abilities.

You'll get more skilled builders, a higher-quality modular home, and a clearer grasp of the customisation process if you work with a company that only builds modular homes. They will thus be able to give you advice on floor layouts and distinctive characteristics that are perfect for your new home.
