Maximize your property's utility storage footprint, secure your vehicles, and build your ultimate backyard workshop with the heavy-duty Duramax 12'x20' Imperial Metal Garage Dark Gray w/ White Trim (SKU: 50951). Explicitly engineered to function as a full-scale standalone vehicle garage, industrial equipment depot, or high-volume storage facility, this premium metal building delivers exceptional walk-in vertical clearance. The Imperial series stands as the definitive, zero-maintenance alternative to costly brick-and-mortar additions or high-maintenance wooden structures.
Unlike cheap, low-grade metal buildings that easily dent, rust out, and warp under high winds, the Duramax 50951 garage is built with thick, hot-dipped galvanized steel framing elements and wall cladding panels. These high-grade metallic profiles are anchored together by heavy-duty internal steel columns and roof trusses to provide maximum resistance against harsh seasonal elements. The striking dark gray wall panels contrast beautifully with the crisp white trim, making this large garage structure a premium architectural asset to any residential yard, workshop pad, or farm landscape.

Refunds/Returns/Cancellation
Refunds/Returns/Exchanges
At Duramax Sheds Direct, we strive to provide our customers with a seamless shopping experience. To ensure your satisfaction, please carefully review our return policy outlined below:
Inspection upon Receipt:
It is crucial that you thoroughly inspect your shipment upon receipt for any signs of damage or missing parts. If you notice any issues, please notify us immediately by sending an email to: support@USpolymersinc.com
Reporting Damaged Shipments:
In the event that you schedule an appointment for delivery and you meet the driver during inspection, we kindly ask you to sign the delivery receipt. If you observe any indications of damage, please make a note stating "damaged" on the receipt. This will enable us to file a freight claim promptly. If the shipment appears to be severely damaged, you have the right to deny delivery. In such cases, the damaged item can be returned for a replacement or refund.
Timeframe for Reporting Damages:
Please note that damages reported after the 5-day window will not be covered at no cost. We strongly encourage our customers to inspect the product upon receipt to ensure its completeness and integrity.
Effective Date:
This policy applies to all purchases made on or after January 1, 2022.
Returns:
Returns will be accepted within 30 days from the date of purchase. To initiate a return, the item must be in its original packaging, unused, and in new condition, including all hardware, instructions, warranties, registration information, and packaging materials. Please email us at info@DuramaxShedsDirect.com to request a return.
Refunds:
Refunds will be processed to the original credit card used for the purchase. The refunded amount will be the purchase price minus three deductions: (1) actual shipping costs to the original delivery location, (2) a 20% restocking fee, which includes non-refundable credit card processing fees charged by the bank, and (3) return shipping to our warehouse. Our warehouse staff will inspect all returns to ensure they meet our criteria. Refunds will not be issued if there are missing parts or packaging, or if the product cannot be resold as new. Unauthorized returns or returns without prior approval will be returned to the customer at their own expense. These charges do not apply in the case of damaged shipments.
Refused Deliveries/Buyers Remorse:
Refused deliveries or returns due to buyer's remorse, failure to schedule a delivery appointment or change of mind will be subject to a refund of the original purchase price. However, deductions will be made for actual shipping costs to and from the delivery location, as well as a 20% restocking fee.
Order Cancellation:
If you need to cancel an order, it must be done before the shipment leaves our warehouse. Failure to do so will be considered a refused delivery. Please note that a 5% cancellation fee will be charged if your credit card has already been processed, as credit card companies do not refund their processing fees.
Damaged Goods/Missing Items:
We prioritize your satisfaction and take responsibility for any damage that may occur during transit. If your merchandise arrives damaged, we will replace the product promptly. It is essential to inspect all items upon arrival and refuse delivery if any noticeable damage is present. Please inform us immediately if you refuse delivery, so we can anticipate the return shipment. If the packaging shows slight damage, please write "Package Damaged" when signing for and accepting the shipment. All damage must be reported within 5 days of delivery, as we are required to file damage claims with our freight carrier within this timeframe.
To report any damage to your shipment, please email Support@uspolymersinc.com.

Questions & Answers
Have a Question?
-
Can the door be moved to the other side?
Yes, the roll top door can go on eithr end and the walkdoor can go on either side.
-
Should I pour a concrete pad and place the garage on top and drill in anchors or put building up then pour concrete in. Garage #5090.
You could do it either way. I personally would pour the pad first making sure it was oversized enough to build the garage on. Then I would assemble the building. A flat level surface will make assembly easier. You may also want to talk to the guy who will pour your pad for you and get his opinion.
-
Are you offering installation?
We do not offer installation at this time.
-
Do you offer financing?
Yes we do! Just click on the words "prequalify now" directly below the add to cart button. You will be directed to our financing partner, Affirm, to get you rapidly approved, so you can continue the checkout process.
