Structural engineers face a shifting landscape. While efficiency, constructability, and cost are key to overall design, a fourth requirement has gained increased attention from stakeholders: sustainability. More clients are demanding precise data on the environmental impact of the materials used in their projects. This is no longer just about meeting a “green” quota; it is about optimizing material efficiency and reducing embodied carbon without compromising structural integrity. 

For the senior engineer managing complex projects and tight timelines, generic data is no longer sufficient. You need specific, verifiable numbers to validate your material selection and meet increasingly stringent building codes and certifications like LEED v4. 

This post explores how Atlas Tube addresses these challenges through clean tube production and the release of factory-specific Environmental Product Declarations (EPDs). We will examine why data transparency is critical for modern structural design and how specifying sustainable steel tubing can streamline your project’s path to approval. 

The Engineering Case for Sustainable Steel 

Historically, sustainability in construction was often viewed as an architectural concern or a line item for operational energy efficiency. Today, the focus has broadened to include embodied carbon—the emissions associated with the manufacturing, transportation, installation, and after-life disposal of building materials. 

For structural engineers, this presents both a challenge and an opportunity. The challenge lies in navigating new sustainability metrics, while balancing budget constraints and design changes. The opportunity, however, is found in material optimization. 

Steel is already the most recycled material on the planet, but not all steel is created equally. The production method matters significantly. By prioritizing sustainable steel tubing, engineers can drastically reduce the carbon footprint of a structure before it is even occupied. This is where the distinction between “industry average” and “manufacturer specific” becomes vital. 

The Role of Environmental Product Declarations (EPDs) 

An Environmental Product Declaration (EPD) is a transparent, objective report that communicates what a product is made of and how it impacts the environment across its entire life cycle. 

Why Specificity Matters 

Many manufacturers rely on industry-wide EPDs. While these provide a general baseline, they often reflect an average that includes less efficient producers. This can penalize projects that use cleaner materials. 

Atlas Tube has moved beyond generic averages by publishing factory-specific EPDs. This level of detail allows you to: 

1. Calculate with Precision: Use exact Global Warming Potential (GWP) numbers for your specific material source, rather than conservative industry averages. 

1. Optimize LEED Credits: LEED v4 and v4.1 offer points for using products with EPDs, specifically those that demonstrate an impact reduction below industry averages. 

1. Validate Design Choices: When stakeholders ask why a specific HSS section was chosen, you have documentation proving that it is the most environmentally and structurally efficient choice. 

Having access to this granular data helps streamline collaboration. When architects or sustainability consultants request carbon data, you can provide verified documentation immediately, preventing delays in the design and construction phases. 

Clean Tube Production: The Atlas Tube Method 

The term “clean tube production” refers to manufacturing processes designed to minimize energy consumption, water usage, and waste. Atlas Tube achieves this through a combination of domestic sourcing and advanced manufacturing technology. 

Electric Arc Furnace (EAF) Input 

The primary driver of HSS’ carbon footprint is the method used to produce the raw steel coil. Traditional Basic Oxygen Furnace (BOF) production relies heavily on coal and iron ore. In contrast, the Electric Arc Furnace (EAF) process uses electricity to melt down recycled scrap. 

Atlas Tube sources its coils from domestic steel manufacturers closest to our factories that mostly utilize EAF technology. This results in steel that creates less CO2 per ton compared to the global average. For engineers, this means that specifying domestic HSS from Atlas Tube automatically lowers the embodied carbon of the structural frame compared to imported alternatives that may rely on blast furnace production. 

Localized Manufacturing and Logistics 

Sustainability is also a function of logistics. Transporting heavy structural members across oceans generates substantial emissions. Atlas Tube operates six factories across North America. By manufacturing products closer to the job site, transportation emissions are reduced. This supports the “regional materials” credit in various green building standards and ensures the material arrives on time, helping you streamline project timelines. 

HSS: Efficiency by Design 

Beyond the manufacturing process, the geometry of Hollow Structural Sections (HSS) inherently supports sustainable design. 

Strength-to-Weight Ratio 

HSS offers a high radius of gyration about both axes, providing excellent compression characteristics. This allows engineers to design columns with a smaller footprint and less steel by weight than comparable wide flange sections. 

• Less Steel: Using less material to support the same load directly translates to lower embodied carbon. 

• Lower Cost: In many column applications, the reduction in tonnage lowers the overall dollars spent on steel, satisfying budget constraints. 

Surface Area and Finishing 

HSS sections have approximately two-thirds of the surface area of comparable open sections. This reduction impacts the finishing stage of a project. Whether the structure requires fireproofing or painting, HSS requires less material to cover, further reducing the project’s environmental footprint and labor costs. 

Navigating Design Changes with Confidence 

One of the most frequent pain points for senior engineers is managing late-stage design changes. A client may suddenly decide to pursue a higher sustainability rating, or a budget change may prompt a re-evaluation of materials. 

Because Atlas Tube provides the largest size range of HSS in the industry—including Jumbo™ HSS—you have the flexibility to optimize designs without leaving the HSS ecosystem. You can swap out heavier wide-flange sections for more efficient HSS options, backed by the specific EPD data needed to justify the switch to the client. 

Furthermore, tools such as the HSS Connections Hub™ help resolve the perceived difficulty of HSS connection design. By streamlining the connection design process and facilitating collaboration between stakeholders, you can help reduce the engineering hours required to adapt to these changes and keep projects on schedule. 

Practical Steps for Engineers 

To leverage the benefits of sustainable steel in your next project, consider the following workflow adjustments: 

1. Request EPDs Early: Do not wait for the sustainability consultant to ask. Download the factory-specific EPDs for the Atlas Tube facilities supplying your region during the schematic design phase. 

1. Compare GWP Numbers: When performing a life-cycle assessment (LCA), compare the GWP of domestic HSS against imported steel or other structural materials. The difference is often significant enough to impact the building’s overall rating. 

1. Utilize Jumbo HSS: For tall columns or long spans, evaluate domestic Jumbo HSS as an alternative to built-up box sections. This reduces fabrication labor and ensures you are using material with a known environmental profile. 

1. Engage Stakeholders: Use the data from EPDs to educate clients. Show them that “sustainable” does not necessarily mean “more expensive” in the long run. Demonstrate how efficient design with domestic HSS saves money and carbon simultaneously due to lower overall weight and clean production techniques. 

Leading the Structural Engineering Community Forward 

The demand for sustainable infrastructure is not a temporary trend; it is the new standard for the built environment. Manufacturers play a critical role, but the structural engineer is the pivot point where material potential meets design reality. 

Atlas Tube is committed to making this transition easier for engineers. By investing in clean manufacturing and providing the transparency of factory-specific EPDs, Atlas ensures you have the tools required to design efficiently. This approach allows you to meet the rigorous demands of modern construction, satisfy stakeholder expectations, and deliver projects that stand the test of time—both structurally and environmentally.
