Steel vs. Concrete: Which Is Better?
Let's begin with the structural composition. Industrial steel is an alloy (metal amalgamation) of iron and contains about two percent carbon. Concrete is a composite material made up of bonded aggregate (fine or coarse) held together by a fluid paste, usually cement. Concrete cures over time to form a durable structure.
Both materials are prevalent in the construction industry, and for a good reason. Without them, the contemporary-built environment we love today would not exist. While concrete may be in demand for its durability, good fire resistance, and 'fast' timeline deliveries, in many ways, steel makes for the better material, both in the long and short term.
Steel has the highest strength to weight ratio of any construction material in existence. Steel's resilience in tensile strength and shear remains unrivaled in the industry. It does not warp, strain, crack, or crumble like wood, concrete, plastic, or other construction materials. Additionally, unlike concrete, steel does not add excessive weight to a building's foundation. Further, steel requires fewer structural members than concrete, which translates to fewer construction materials needed on or off-site. While concrete takes a few days to dry, steel structures are usable soon after being set up.
In terms of aesthetics and structural design flexibility, steel, again, emerges as the winner. Steel integrates into virtually any design, as well as supports a multitude of loads. One may argue that concrete can be used for multiple designs, but it does not possess the versatility and ductility that makes steel such an attractive building material. When it comes to the best blast-resistant buildings, it is steel's flexibility, elasticity, and RedGuard's solid engineering and design prowess that makes our steel blast-resistant buildings exemplary when it comes to worksite safety. We employ steel in our blast-resistant buildings because it gives our clients the flexibility they need to meet and exceed their needs.
Further, steel is cheaper to build and maintain than any construction material with similar strengths and characteristics. Costs are an integral consideration of any building project, and when steel is used to construct blast-resistant buildings, strength, quality, and durability go hand in hand with affordability. Steel is also more eco-friendly as 85% of the world's available steel is recycled, including 99% of structural steel after demolition. You cannot reuse or recycle the materials in a concrete structure.
Concrete structures have their benefits, but in comparison to steel, they stack up as expensive, take more time to prepare, cure, and install, and add considerable weight to foundations.

Safety And Steel Buildings
We have already established that steel, in many ways, is the stronger and safer building material. Concrete may have considerable strength, but it fractures very easily under tension due to its brittle nature. This characteristic makes concrete a safety hazard in blast-resistant buildings as fragments from fractured and dislocated concrete are considered a significant source of injury.
As the authors of a peer-reviewed research paper in ScienceDirect conclude, concrete is not only an expensive solution, but it also adds considerable gravity loads to the foundations of a building while requiring a significant time frame to install. “The possibility of spalling and fragmentation are also disadvantages when concrete and masonry are exposed to an airblast load because one of the main sources of injury in an explosion is high-velocity fragments. The loss of material also weakens the structural component which may affect the integrity of the building.”
When coupled with skillful structural design, steel's tensile strength makes it the safest option for blast-resistant buildings. RedGuard's proprietary design encompasses structural support in the walls with strategic placement of steel throughout the building. Our design also ensures that the building transfers any energy from a blast away from the interior spaces where staff and valuable equipment may be located. Redguard's blast-resistant buildings are tough and durable from the inside out.
Don't just take our word for it; watch how we publicly tested and proved our claims. What do you get when you combine 6,000 pounds of highly explosive ammonium nitrate/fuel oil with RedGuard's state-of-the-art blast-resistant building, and unparalleled industry-leading safety innovation? Confidence that you are in the safest hands.
Our test building survived with no structural damage and only shifted a mere ¾”. The crash test dummy we placed inside to simulate a real-life working environment only detected that minor injuries to ears or hearing could occur, but overall was unharmed, demonstrating the protection our blast-resistant buildings offer in case of any unfortunate accidents. We do not claim that there will be no damage whatsoever, but our design has been rigorously tested to ensure any damage is minimal and contained, with little to no grievous harm to human beings.
We publish our test results to assure our clients of the strength and capabilities of our blast-resistant buildings and confirm our commitment to safety.

Quality of Steel as a building Material
As materials, both concrete and steel have different qualities that can help you determine which is best for your blast-resistant buildings.
As materials, both concrete and steel have different qualities that can help you determine which is best for your blast-resistant buildings.
In terms of strength, it is arguable that both materials are strong. However, steel trumps concrete because of the strength-to-weight ratio. As mentioned before, it has the highest ratio of all construction materials and is therefore significantly stronger than concrete. Adding to its strength is steel's ductility and flexibility. You can mold and manipulate concrete, but only to a certain extent, while steel can be adapted to fit virtually any concept or changes to a structure's design.
Steel is also lighter in weight compared to concrete. As a material, it is seemingly 'complete,' making it easier to transport, construct, and even maintain. On the other hand, concrete requires the mixing of cement, sand, water, among other additives, and consequently does not offer the same convenience in transportation, processing, and handling as steel.
Regarding construction, steel structures are more time-saving and effective. Steel structures can be fabricated off-site, like RedGuard's modular blast-resistant buildings, then transported to the site. Once on-site, multiple sections of the structure can be joined, leading to faster turnaround times and effectively reducing possible material waste. In stark comparison, non-modular concrete structures must be cast bit by bit, step by step, and while it dries considerably fast, it takes 28 days to cure.
Further, steel structures require less foundation setting than concrete structures. It is also far easier and more environmentally friendly to bring down steel structures than concrete structures. Should you want to move or do away with your blast-resistant building, steel will prove easier to move and will leave you with valuable materials that you can repurpose elsewhere.
It is true that concrete is fireproof and does not suffer the same damage from fire as steel does, but quick and readily available solutions can remedy that. Steel can be made fireproof by using fire-resistant coatings and barriers and incorporating active measures such as cooling systems and sprinklers. These measures are readily provided in RedGuard's SafetySuite buildings. We will work with you to choose the solutions that best suit your needs and budget.

Setting a Budget For your Steel building
Steel has proven to be significantly more economical than concrete in modular building construction. Recycling has made steel more abundant and cheaper to procure than concrete. Additionally, it is lightweight, making transport and handling faster, and eventually, more affordable. In contrast, concrete involves incorporating many ingredients such as cement, sand/gravel, water, among other additives - making it heavier and difficult to transport. And because it is not as strong on its own, it may require the incorporation of rebar. The addition of rebar will take up more construction time and an accompanying hefty bill.
Design-wise, steel also emerges as the more cost-effective option. Our SafetySuite blast-resistant modules give you the flexibility to design the exact kind of space that works for your organization without compromising on quality and maximizing savings.
A study found that using steel in construction results in a 5% to 7% decrease in construction expenses than concrete. With RedGuard's blast-resistant buildings, our prices extend the same cost savings we enjoy from using steel.
Also, steel requires fewer pieces of structural equipment such as cranes, installation machinery, and support materials, significantly reducing the procurement budget for other building components.

Timeline For Planning a steel blast-resistant building
At RedGuard, we have a simple four-step process to help you construct the safest and most durable building that suits all your diverse needs.
We initially start at the concept stage, where clients are in the driver's seat. We help you develop a concept that incorporates a study of your site plan, your existing buildings, and an analysis of your day-to-day operation.
Once the concept design is complete and approved by you, construction in our fabrication center begins. Doing this at our site ensures that construction does not interfere with your daily operations. This approach also reduces the number of bottlenecks associated with production. Our worksites are state-of-the-art, and our staff is highly trained to produce the highest quality blast-resistant buildings in the fastest times possible. The build time depends on the size of your structure and unique needs. For example, a simple three-plex or smaller may take 16-20 weeks to construct once the designs are approved. Larger and more complex blast-resistant buildings will take longer to build. Once complete, we ship the whole building to your site.
Site installation commences upon successful delivery, where RedGuard will handle all installation. Our expertise will ensure that your blast-resistant buildings are expertly installed and set up for immediate use.
As the process comes to a close, our final step will leave you fully operational, secured in industry-surpassing safety. Fortunately, we are only one phone call away and always on standby to assist with any questions or repairs that may be needed.

Choosing the Best Vendor For A Steel Blast-Resistant Building
We trust that you now understand what a solidly blast-resistant building ought to be; made from steel, using a design that has passed a blast test, versatile and adaptive to your needs, as well as one that is cost-effective and durable. However, how do you go about choosing a vendor who incorporates all of this into your desired blast-resistant building?
We recommend choosing a vendor who is an industry pioneer and employs and works with the top experts in the industry. With more than 20 years of experience, we are as functional, durable, versatile, and reliable as our blast-resistant buildings. Our expertise is regarded as an industry benchmark, and our team comprises subject matter experts in blast resistance. This is the most crucial factor you should consider when evaluating vendors for your blast-resistant building.
Secondly, your vendor needs to have durable, comfortable blast resistant buildings that have been tested for reliability and utmost safety. RedGuard, without a doubt, shines in this aspect as we are one of the few companies to publish our blast results. We firmly believe in our product, and we would never send out any product that has not met our rigorous high-quality standards.
A third criterion worth considering is the speed of production. How quickly does the vendor produce your desired blast-resistant building? How fast will they deliver the completed structure? Our speedy off-site production and affordability ensure we lead the industry in turnaround times.
The adaptability of design concepts would be the next step of evaluation. Is the vendor open to working to suit all your needs, or will you be forced to settle for one of their structures without considering what suits your unique needs? At RedGuard, we designed our tried-and-tested production process with our clients in mind. Do we have various set designs and material processing in place? Certainly, but they have been designed to adapt to your needs, which ultimately become our goals. As industry pioneers and visionaries in this space, we have designed blast-resistant structures that cater to the various needs of our diverse clientele. If you can dream it, we can build it.
Finally, vendors must uphold the highest safety standards, both in their organization and as evidenced by their product. Do you think your vendor of choice should be recognized and awarded for its safety practices and process? We think so too.

The Power Of Steel Blast-Resistant Buildings
Steel blast-resistant buildings, and steel structures in general, offer strength, versatility, flex, and cost-effectiveness that other construction materials cannot provide altogether. Concrete's saving grace may be its fire resistance capabilities, but steel can also be made fire-resistant through coatings, barriers, and other active cooling measures such as sprinklers – all of which are accommodated by RedGuard's SafetySuite portfolio. However, concrete cannot make up for its brittleness, lack of tensile strength, and shear. These attributes are immutable and irreducible for quality blast-resistant buildings. Ultimately, when it comes to concrete vs. steel – steel wins every time.
We love it when our clients challenge us with their unique blast-resistant building ideas, and to date, we have always stepped up to the plate and knocked every site design concept out of the park. We are recognized in the industry for our unmatched safety standards that we incorporate in our production facilities and workspaces and inform every inch of our blast-resistant building modules.
