Lifetime Garage Sheds - 60237 Storage Building 11 x 21 - Tri-Fold Doors

Welcome to the largest pre-fabricated Lifetime storage building garage shed available. The 60237 features nominal dimensions of 11 feet wide by 21 feet deep. This large outdoor storage shed features Lifetime Products tri-fold door design, which creates a massic 9-foot opening. The opening is typically large enough to fit a full-size vehicle into the building (check your measurements before ordering). Complete with 3/4-inch floor, the 60237 encloses an 200.8 square feet of floor space. The added depth of this garage shed also provides added room to work around whatever you have parked in the shed. Like other Lifetime sheds, the 60026 is made with high-density polyethylene (HDPE) plastic, which will not fade, crack, or peel in the sunlight. Powder-coated steel reinforcements strengthen the walls, roof, and doors.

Wall, Roof, and Floor Construction

The walls, roof, and floor are made with HDPE plastic. This plastic is easily blow-molded into designs that provide the 60237 Lifetime garage shed with an attractive look. The walls and doors features a wood-grain impression. The roof features simulated shingles. Thus, the 60026 gives you all of the desired looks of a wood shed without the worries of wood rotting, or replacing shingles. The floor of the shed features a blow-molded design that helps resist slipping; which can certainly help with oil on the floor as you work on your car.

Walls, Doors, and Roof Trusses

The walls, doors, and roof trusses of the 60026 are reinforced with powder-coated steel. This steel structure helps to strengthen the shed weight capacity as will as improve the rigidity of each of these components. The powder coating on the steel helps the metal resist rusting, making Lifetime sheds well-suited for wet and dry climates. Along each seam of the panelling design of the shed roof the steel roof trusses act as channels to help move any water seapage through the seems back out of the shed keeping the shed contents dry.

Low Maintenance Required for Lifetime Sheds

Lifetime garage sheds do not need to be repainted. HDPE plastic will not fade, crack, or peel in the sunlight. HDPE plastic is also easily cleaned, typically requiring only soap and water. This easy maintenance is well-suited for garage sheds as you get oil and dirt on the floor moving vehicles in and out of the building.

What is the Size Good For?

With a length of 21 feet, the 60237 LIfetime garage shed should easily be able to fit most any car. ATVs and riding lawn-mower storage is also useful. Typically, the 60026 should be able to fit multiple ATVs, making the shed useful for winter or seasonal storage of your off-roading vehicles. This model also comes with 6 windows on the walls that can be opened for improved ventilation. This will help improve air flow while you were on your vehicles (never leave a vehicle running while you are inside the building), or just to keep the building cooler during hot Summer days.
