Perfect building perfect customer service and this is my 3rd structure they have built for me. Love them!

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.
This building looks amazing. The color match was perfect. The crew were very polite and worked hard. They took a magnet sweep to make sure they didn't leave any screws or metal pieces on the ground. I highly recommend this company
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.

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.
Very easy to purchase what was needed. Melissa was very helpful when I talked to her onto phone and sending blueprints to make sure I got what I was wanting
Love the 3D builder and how you can see every detail and point of view. Easy to order and choose options.
I loved the 3D builder option! To do everything on-line and go straight to the checkout was refreshing.
So far, the shopping and design experience has been incredibly easy and much more forthcoming than any other carport seller/installer out there!! Really looking forward to the install.

My 2nd time ordering from Alan’s Factory. Returning customers are the best form of recommendation!

Frequently Asked Questions

Most projects can be built with standard construction tools like a drill or screw gun, tape measure, level, ladders, and basic hand tools. The framing is pre-engineered and assembled with bolts and screws, so no welding is required. For larger buildings, some customers choose to rent a lift or similar equipment to handle heavier parts safely.
Yes. These kits are DIY-friendly, but you can absolutely hire a local contractor or crew to build it for you. Alan’s Factory Outlet does not provide installation for metal building kits, so any labor would be arranged directly between you and your installer.

They are shipped via Freight with a Semi Truck and a Forklift is required at time of delivery to unload the Metal Building Kit.
