Features

  • Double read before buying: For maximum stability, we strongly recommend building a concrete foundation and using our included anchors to permanently secure the shed. If you plan to install the shed on a soft surface (such as dirt, soil, or gravel), you must purchase separate heavy-duty auger anchors. We recommend a length of at least 30 to 36 inches (75-90 cm) to ensure they grip deep into the ground, well below the frost line, for a firm and secure hold.
  • UNLEASH 260 SQ. FT. OF MASSIVE STORAGE: Stop letting clutter win. Our expansive 13x20ft metal shed provides a colossal space, perfect as a full-size garage, a spacious workshop, or a secure outdoor storage building. With an 8 ft peak height and wide-swinging double doors, you can easily drive in your car, park your boat, or organize all your lawn equipment and tools without compromise.
  • ALL-WEATHER ARMOR WITH REINFORCED TRUSS SYSTEM: Engineered to endure. Constructed from heavy-duty(23 gauge) , multi-layered galvanized steel and featuring a unique double-reinforced internal truss and beam system(18 Gauge) (see images), this metal building stands defiant against harsh wind(150mph), heavy snow(50-100 PSF), and rain. Its not just a shed; it's a permanent, weatherproof fortress for your valuables.
  • SUNLIT & VENTILATED, DAY AND NIGHT: Work in a bright, comfortable space without running up your electric bill. This outdoor shed is intelligently designed with 4 transparent polycarbonate skylight panels that bathe the interior in natural light. Combined with 4 ventilation windows, it ensures constant airflow, preventing m oistur e and m ustin ess, making it an ideal environment for any project.
  • SECURE & ACCESSIBLE DUAL-ENTRY DESIGN: Enjoy unparalleled convenience and security. A wide, lockable front double door allows for easy access for large items, while a separate, lockable side door offers quick walk-in entry. Whether you're setting up a tool shed or a motorcycle garage, your belongings are kept safe with included anti-theft locks.
  • COMPLETE GARAGE KIT FOR YOUR NEXT PROJECT: Everything you need for a successful build is in the box. This comprehensive shed kit includes all pre-drilled panels, a full steel frame, skylights, windows, a robust ground anchor kit for stability, and a detailed instruction manual with a step-by-step installation video. While assembly is a 3-5 person project, the result is a professional-grade structure you can be proud of.

  • Snow load strength of roof system
Style: 13x20 FT
Great Metal Shed. Materials at good quality. Really like the two main support that span the width of the shed. Took about 8 hours with 3 people to put up the walls and roof. Took another 8 hours with one person to do the 3 doors and 3 windows. Looks very nice!!! Especially for the price!!

Style: 13x20 FT
Received 6 box. Super fast delivery great condition via FedEx. All materials and installation guide on package. I’m super happy. This is looks like two bedroom size house. Long lasting and Solid material. It take me about full three weeks for installation myself. If you are not handy man don’t try to installation. Must be leveling and square 4 corners before installation. Just follow there installation guide step by step. Don’t skip anything. also there are installation video on site. Buy with confidence. I have no question about product and customer service. Highly recommended again highly recommended. Appreciate for great product. ... show more

  • Don't go by any of the dimensions listed in item description if building on a wooden platform
Style: 13x20 FT
Item is solid and well built for the price and instructions ( written along with video) are fairly straightforward and not difficult to follow. My main issue is that I am assembling it on a wooden platform and none of the dimensions listed in the item description correspond to where it will attach to the platform. I pre-built my platform so that I could start assembling the shed as soon as it arrived. Due to none of the dimensions matching, I needed to make some modifications to the platform that I had already completed. Also be aware that the usable space is not 13x20. That is the size with the roof overhang. ... show more
