This metal hardness chart organizes different types of metal using the Mohs hardness scale, a metric used by scientists to determine the scratch resistance of different minerals. With diamond at the top of the scale at a score of 10, elements and alloys can fall along the metal hardness scale from 10 (the most scratch-resistant) to 1 (the softest). We’ve arranged common metals in order of hardness in our handy chart and in this list. Our list includes different kinds of metal from metallic elements like silver to common alloys like steel.
Yes, we have a wide variety of sizes available for both our steel and metal garages. They can be 12 feet, 18 feet, 20 feet, 22 feet, or 24 feet wide. The triple-steel garages are built in 26-foot, 28-foot, and 30-foot widths. We also have 40-foot-wide models, available in lengths of 32 feet, 34 feet, 36 feet, 38 feet, and 40 feet.

The lengths start at 21 feet and get longer in 5-foot increments: 26 feet, 31 feet, 36 feet, 41 feet, 46 feet, 51 feet, 56 feet, 61 feet, 66 feet, 71 feet, 76 feet, 81 feet, 86 feet, 91 feet, 96 feet, and 101 feet.

Why do our customers need motorhome covers? Metal RV covers prevent the snow, rain, and hail from causing rust and otherwise damaging your RV. Metal carports are stronger and offer more protection than a cloth tarpaulin: Cloth can cave in and tear, leaving your RV vulnerable to the elements. And you don’t even need to own an RV to benefit from camper covers: For RV owners, they offer protection for a costly vehicle, but if you’re not an RV owner, a portable RV carport can also serve as year-round shelter for your car, truck, motorcycle, or ATV. And once your carport is set up, it requires no additional maintenance.

Our sheet metal buildings for sale protect your valuables from thieves and intruders on your property, too. Instead of parking your car, ATV, truck, or bicycle outdoors where thieves can see it, store it inside your metal building where it is out of sight. Our metal buildings serve as a deterrent to thieves, who want to focus their efforts on easy targets. That’s just one of the many reasons why so many people choose to buy one of our metal storage buildings for sale.


Working with General Steel is a collaborative process that ensures that your final product reflects your specific needs. The process starts with a two-way conversation between you and our experienced team. We want to know exactly how you will be using your garage, how it will fit on your property, and your ideas for interior and exterior design, among other factors. We then research the location of the garage to ensure that it’s equipped to withstand the wind and snow loads of your area as well as any insulation requirements.
Metal garage doors can be placed on the end or on the gutter side like in this picture. Please keep in mind that if you order metal garage kits with the garage doors on the side, the leg height needs to be 2 feet taller than the height of the garage door; when you get the garage doors on the end, the leg height only needs to be 1 foot taller than the height of the garage doors. Also, steel garages come standard with 29-gauge metal siding going horizontal, but you have the option to upgrade to vertical sides and a vertical roof as shown in the picture.

Did you know that adding a high-quality metal garage building to your property could increase the value of your home? One study conducted by Florida State University concluded that the addition of a new garage could add as much as 13% to your home value. Of course, as is true with any home improvement project, the quality of the garage building will go a long way in determining what sort of equity gains you will realize over time.

“Timing was an extremely important factor for us and we knew no one in America could get a steel building on site quicker than Armstrong Steel - so the choice was easy. With all of the unscrupulous steel building companies out there today, we're glad we chose Armstrong Steel because we got what we paid for and THEN some AND they came through in a pinch!”
