Mini Storage

Need Space? You Need the General!

The mini storage industry has been a top growth sector year after year for over 35 years. With 10% of the American population renting storage for an average of 10 months, vacancy levels are at historic lows, resulting in higher rent and swelling net incomes for American mini storage operators. This upsurge in net income is also driving cap rates upward annually which is enticing real estate investment trusts to search for mini storage businesses for sale throughout the country.

Advantages of Our Mini Storage Buildings

While you do have options when it comes to storage, here’s why General Steel has been a leader in American mini storage buildings for over two decades.

Durability: Protecting Your Investment

In the self-storage business, using low-quality storage units can be a serious mistake. Cheaper quality units are not as durable and can be expensive to maintain. High-quality General Steel storage buildings offer increased resistance to external damage factors and normal wear from common use, resulting in an overall lower cost of ownership. We use high grade steel which provides straight walls, tight connections, and increased durability. Our buildings are designed to withstand the wind, snow and seismic conditions in your area and have the longest warranties in the industry. Therefore, you can focus on running your business rather than worrying about whether or not your investment will last; since our buildings are virtually maintenance free and will last for generations.

Versatility: Customization Options

Customizing the functionality and look of your units is one of the most important decisions for your business. For example, the color scheme you choose will be essential to catching the eye of potential renters and help you reduce the time it will take to reach full occupancy. Your color combination may also be an important factor in getting your project approved by your local building department. Take a look at some examples below and take note of which colors you prefer.

Competitive Pricing: Buy Right the First Time

At General Steel, we understand that buying your prefab metal building at the right price is just as important as purchasing or leasing your land at an affordable price. After all, the level of your initial investment will ultimately determine when you breakeven and start to turn a substantial profit. General Steel has the highest purchasing power in the industry which results in a better building price for you. If you happen to find a lower price, General Steel will never be undersold if you take advantage of this apples to apples price guarantee..
