Did you know that 12-gauge steel is 2.86 times stronger than 14-gauge steel, even though it is only 0.031 thicker? That's right! Metal buildings are getting popular in our country due to their versatile designs and practicality. Whether it is a residential, agricultural, or commercial setting, these structures offer unmatched utility for various needs.
However, not all steel structures are made the same. When buying, you must give priority to the key features to ensure durability, safety, and a solid ROI. One of these features is the high-quality 12-gauge of steel frames. Before we dive into what these are, let's understand the meaning of a metal structure gauge.
What Is Metal Building Gauge?
The metal building terminology, 'gauge,' refers to the thickness of the steel that is being used in the construction. It determines the strength, durability, and load-bearing ability of a building.
A gauge is represented in two ways – "gauge" or "GA".
The gauge number has an inverse relation with the thickness – the lower the gauge number, the thicker and stronger the steel will be. For example, have a look at the table below [source: cornell.edu]:
As you can see, 12-gauge steel is thicker than 14-gauge steel and more robust. Think of it as a wire cable. A 12-gauge wire cable is thick and can carry more electricity than a thinner 14-gauge wire. So, the lower the gauge, the greater the strength will be.
A 12-gauge steel frame can be designed to withstand high-speed winds of up to 180 miles per hour and heavy snow loads of up to 80 pounds per sq. ft. This helps the structure to sustain in extreme weather conditions.
What Makes A 12-Gauge Metal Building High-Quality?
Strength And Durability – A 12-gauge stands out due to its thickness and better load-bearing capacity than a higher gauge number steel. It can stand firm during strong winds, snow loads, and storms, and has a high resistance to dents, bends, and corrosion.
This strength translates to the real-world benefits, such as:
- It's less likely to warp under pressure
- Remains smooth and dent-free
- Holds up under extreme weather events
In areas like Tornado Alley, Rocky, and Western Mountains, a 12-gauge steel adds weight without compromising on structural integrity.
Longevity And Low Maintenance – Since 12-gauge steel is robust, it lasts longer and needs less upkeep, repairs, and replacements compared to higher gauge frames. You can enjoy the durability of the structure without worrying about wear and tear.
For example, a lighter gauge may need frequent touch-ups after minor impacts, but a 12-gauge is built to withstand everyday challenges.
Cost-Effective – While the upfront cost is slightly higher than that of thinner-gauge materials, a 12-gauge comes with superior durability and lower upkeep, making it a cost-effective choice in the long run. It is ideal for many applications, such as a metal garage, a steel carport, an agricultural barn, and a steel outdoor shed. It gives an ideal combo of quality and value.
Versatility – The multi-functional 12ga metal building can be used for a wide range of residential dwelling units, commercial workshops, processing factories, retail spaces, etc. This ability to cater to a wide range of audiences and sectors makes them a preferable choice.
Key Features Of A 12-Gauge Steel Structure
Steel Quality And Certifications – Now, the strength of the steel depends not just on its gauge but also on its quality. So, we recommend always looking for certifications or standards that confirm that the steel meets specific standards or quality benchmarks (e.g., ASTM – American Society for Testing and Materials).
Moreover, it ensures that the supplier has sourced high-quality materials for steel building manufacturing. Opt for rust-resistant metal that's properly treated to endure environmental factors.
Coating And Finish – A protective coating plays a significant role in extending the life of a 12ga steel. You can opt for 100% galvanized steel that comes with molten zinc coating to prolong the lifespan of steel frames and protect them from rusting.
Some high-quality paint finishes, like V-resistant, add an extra layer of protection while enhancing the structural aesthetics.
Framing And Structural Integrity – You should choose robust framing, braces, and parts with secured connection methods (bolts, fasteners, etc.) for higher strength. It is also important to have proper engineering to ensure the building can withstand local weather conditions and meet local building construction standards.
Panel Overlap And Attachment – The way metal panels overlap directly impacts weatherproofing and structural integrity. High-quality fasteners or welding ensure the building will remain firm and secure.
Doors And Windows – High-quality steel frames and metal panels deserve equally robust doors and windows to maintain overall strength. That's why you should pay attention to the strength and quality of the seals and components, including hardware on doors and windows.
Choose reinforced windows and insulated doors for a comfortable indoors and to prevent moisture-related damage.
Foundation Requirements – A high-quality 12-gauge steel will need a deep and more robust foundation for structural stability. You can choose concrete slabs, piers, etc., which are highly stable, more load-bearing, and provide support for the structural weight.
Ensure the site is prepared before leveling and laying concrete to set for long-lasting durability.
Why Invest In A High-Quality 12-Gauge Metal Structure?
Here are some of the benefits of choosing a 12-gauge steel frame for a building:
Questions To Ask Your Metal Building Dealer Before Buying 12-Gauge Structures
1. What is the grade and origin of the 12ga steel you use?
2. What type of coating do you use on your metal panels and frames?
3. Can you provide engineer-specified wind and snow loads for your metal building?
4. What types and quality of fasteners, screws, and joints you use?
5. Is there any warranty on the metal structure?
6. Do you provide metal buildings that meet local building codes and rules?
7. What is included in the final quote for a building?
You can ask more questions depending on your specific requirements, such as if you are buying a metal commercial building, you can ask if its quality complies with commercial building codes, where you want to install it, what after-sales services and warranties you will get on the structure, and design available to suit your brand identity.
So, Are You Ready To Upgrade To A 12-Gauge Steel Building?
By investing in a quality 12-gauge metal building, you get a durable, reliable, and long-lasting structure that stands the test of time. Its robust nature ensures long-term protection and performance. Choose a reputable supplier and manufacturer for excellent craftsmanship to enjoy peace of mind.
