Highly Rated by Customers Across Southern Illinois
Customer service was top notch! Love the new building. Contractors that set it up were well trained and did an amazing job
Perfect building perfect customer service and this is my 3rd structure they have built for me. Love them!
This will be my third carport from Allen's and as always the experience is always perfect!!
This is the 4th building I've ordered from you so far. Always been extremely pleased. Have no reason to think this time will be any different. You guys always do a AWESOME job!!
This business and site is awesome! You get to customize your carport or garage via computer, tablet, or phone! It's very user friendly! You just have to know what you want, take your time, and select what you like & want!
Easy navigation on website. Loved the customization feature. Exceptional quality of product & installation.
We were so excited to finally purchase and have a new carport installed. The entire experience was better than we could have imagined and it looks great!!
Love the site. Easy to use and design carport and see what we are getting. Was able to design my carport to my specific design and see what it would look like. Was able to add just the things I needed and nothing else. Loved using the site. If I ever need another shelter, will order from Alan's again.
Very straightforward. Selected the model, color, size and options online. Made the downpayment. Be sure that the site is ready as per their specifications and the install will go smoothly.
I loved the interface and being able to build what I wanted and see a price as I went along. That’s what sold me, if I couldn’t see the upfront price I would have gone somewhere else.
Excellent and clear quick responses to all questions. The 3-D display makes it easy to create the right building. And reasonable in cost as well. Thanks..
I love dealing with pros and you definitely fit that category. It nice to have an easy time of it and a turn key job. Thanks for the work you do. Randy Crenshaw
Uou make it so easy to do this online. It is fantastic! I love the options on these things and the ability to add sides or ends at a later time if desired.
My order was handled in a professional manner. Delivery and construction was earlier than anticipated. Construction crew were professional and very efficient with their time. I would definitely recommend Alan Factory Outlet for a quality product and professional installation.
Easy ordering online,installers did an excellent job,very impressed with build quality, sturdiness and overall purchase experience.
Easy to use, witnessed an installation in Montvale Va yesterday. Very impressed with the crew and product.
I am happy with the product and installation. It was quick and painless and looks and performs great
My son recommended your business since he was very happy when you did his carport. The web site is easy to understand.
From the 3D builder to a very good customer service rep over the phone this was by far the easiest time I’ve had ordering a structure
I greatly appreciate the functionality of this site. Making changes to the design and seeing them reflected in the finished product is a game changer.

Frequently Asked Questions
Foundation requirements depend on the metal building size, its intended use, and your local building codes. Always check local regulations first for specific size, thickness, or footing requirements.
We recommend your concrete slab to be at least one foot longer and one foot wider than your metal building, but you can make it bigger if you want to have a small wraparound sidewalk.
You can use our Concrete Pad Size Calculator as a general guideline for planning, but keep in mind that local codes supersede our recommendations.
We offer free delivery and installation on all our carports, metal garages and buildings. Installation time depends on size:
Small carports (12×20 or 18×20) can be installed in a few hours.
Larger carports (24×25 or 30×20) take a full day.
Medium size metal buildings (30×40 or 40×60) take 2 to 3 days.
Large metal buildings (50×100 or 60×80) take 3 to 5 days.
As long as your foundation is level and ready we will take care of the rest!
We offer two types of insulation: Double Bubble and Woven R-17. Double Bubble insulation helps with moisture control but does not provide temperature regulation. Woven R-17 insulation helps with both moisture and temperature control, has an R-Value of R-17. If you’re not sure which one is best for you, check out our Metal Building Insulation page for more info!
Our metal buildings are engineered for durability and designed to meet or exceed standard requirements. For areas with harsh weather, we offer upgrades like thicker 12-gauge steel framing and building certifications for specific wind speed ratings (e.g., up to 140 mph or more) and heavy snow loads (measured in pounds per square foot).
Opting for features like a vertical roof style also enhances performance in heavy snow regions. Discussing your local conditions with our building specialists will help ensure your structure is properly configured.
Beyond the foundation itself, the most crucial preparation step is ensuring your site is level (or within a few inches of level) before the installation crew arrives. For a seamless installation experience, you must also provide clear, unobstructed access to the building site for our delivery truck and crew.
Yes. You usually need a building permit to install a metal building on your property. However, requirements for metal buildings vary greatly depending on your specific location (state, county, city) and the size or intended use of the structure. For example, in some jurisdictions, you can install a carport without a permit since it’s not considered a permanent structure.
You must check with your local building department to determine if you need a permit, and you have to get it before we schedule your metal building’s installation. We can provide standard engineered drawings upon request to assist with your permit application process if needed.
The price of metal buildings depends on factors like size, style (roof type, etc.), the materials you choose (steel gauge, siding options), and any added features like doors, windows, or insulation.
You can check prices quickly by using our custom carport pricing tool or garage design builder—just pick the structure you need, customize it, and get real-time pricing!
All of our metal buildings come with a 1-year workmanship warranty from the installation date. Additionally, if you upgrade to the optional 12-gauge steel framing, you receive a 20-year rust-through warranty on the framing and most roof panels.
