It’s a balancing act. You need enough space for the business you have now, as well as the ability to expand. Many owners have discovered that the two best options for cost-effective business buildings – especially warehouses – is either concrete or steel.
Both are excellent choices in terms of durability and low maintenance, but ultimately you may discover that a pre-fabricated metal and steel building is the best choice. Here’s why.
Bumping Up Against Size Limitations
No one argues that steel is as moldable as concrete, but the trade-off is weight. Using standard information about concrete, an 8 foot by 10 foot concrete wall that’s 6 inches thick would weigh about 6,000 pounds.
Concrete’s weight places limits on the available span of a building structure. You’ll need concrete supporting columns to support the extra weight, too. These will interfere with interior open space, as well.
Steel has one of the highest ratios of strength to weight of any construction material. This allows for buildings that are free of support columns, so you’ll have more usable floor space. For example, our Miracle Truss® designs allow for roof pitches all the way up to 18:12 and clear-span widths of up to 125 feet, along with wall heights of up to 30 feet. Because of the pre-engineered modular nature of steel buildings, there’s practically no limit to the length of their construction. This means it’s easy to expand your Miracle Truss® building any time in the future by simply adding more elements from us.
Steel is Less Expensive than Concrete
Here’s the thing about concrete construction. It’s going to involve steel reinforcement. So you’ll be paying for both materials. That’s not really why concrete ends up being more expensive, though. The extra weight of concrete means you won’t be taking a DIY approach to construction.
Miracle Truss® manufactures buildings as kits. It starts with a basic set of drawings that are generated for your specific state to help you sail through the building permit process. The materials are pre-fitted at our factory before they’re sent to you. The trusses bolt together in four easy pieces.
Way Down the Road: The Recycling Factor
Hardly anyone is thinking about it when they’re just putting up a building, but what’s going to happen to it much later down the road? Steel and concrete are both recyclable materials, but concrete is more expensive to break down and reuse. Much of it ends up in our landfills. Steel is 100% recyclable. It’s a clear winner.
Both are Good Choices, but Steel is a Better One
Steel beats out concrete in cost, strength, flexibility, and safety. Best of all, you can put up a steel building from Miracle Truss® yourself. Learn more about the Miracle Truss® advantage.
Costing a project is not just about the price of materials. When mobilizing resources for a blast-resistant building, we need to consider direct labor costs, business disruption during the build, and even the cost of maintenance during the asset's lifespan.
All factors considered, steel is more affordable than concrete for blast-resistant buildings.
Why Steel is More Cost-Efficient for Blast-Resistant Buildings
From ensuring API compliance, to lower labor and maintenance costs, below are a few factors that make steel a more affordable option than concrete.
API Compliance
The American Petroleum Institute (API) has invested time and resources to come up with safety standards that serve to protect employees in the industry. One of their recommended practices, specifically API RP 752, identifies unreinforced concrete as brittle material that should not be used for exterior walls. Steel, however, has been tried and tested to withstand the pressure exerted by a blast wave and protect the occupants within it.
Lower Labor Cost
Steel modules can be erected in as little as a few weeks, depending on the design. If one of the predesigned plans fits in with your needs, the process is simplified even further, and you can have a complete workspace ready in weeks. With concrete, the build has to be systematic, takes time, and requires more workforce. In addition, steel blast-resistant buildings can be mostly built offsite and then quickly assembled, further shortening the duration of the build, and decreasing liability.
Lower Maintenance Costs
Over time, concrete buildings require more touch-ups than steel. As part of the curing process, cracks may develop and are either structurally detrimental at worst and unsightly at best. Steel is more malleable and enjoys some elasticity, allowing it to expand and contract marginally without affecting the structural integrity of the building. Fireproofing can be added to the structure by applying sprayed fire-resistive materials (SFRM).
Less Disruption
If you add a building to an already occupied lot, there is bound to be a loss in productivity. This cost is tough to quantify, but it does affect the business.
If the building site is unoccupied, there is still a need to secure the site during the build. Meetings and site visits will also take up your time for the duration of the project.
The best way to minimize this disruption is to take the least amount of time possible, and that's where steel provides an edge.
Steel is Light
Just like an ant can withstand a force 5,000 times its weight, steel is light, yet strong. Because of this, small units do not require a foundation. This quality is the reason it is also possible to build off-site and transport ready-to-build units to the construction site.
Another advantage of steel is that it requires fewer pillars. This fact gives you more room to create a safe, comfortable workspace.
What Does this Mean for Safety?
Affordability doesn't mean sacrificing safety. In fact, steel is more durable than concrete and has a better return on investment in the long run.
Steel offers a greater return on investment for blast-resistant buildings because it is strong, durable, and API compliant. Steel buildings are completed faster and disrupt your operations less than on-site builds. Additionally, steel is not only a cheaper material than concrete, it is also cheaper to maintain, and requires fewer man-hours to install – all without compromising safety and quality.
