Lifetime Storage Buildings - 6433 Outdoor Shed 11 x 11

Lifetime storage buildings are the next size larger in the Lifetime shed lineup. The 6433 increases the width of the building to 11 feet. The doorway is also a bit larger. This storage building size can more easily fit larger storage items like riding lawn mowers and ATVs while still having ample room around the sides of the stored item to walk around and reach the other parts of your shed. 11-foot wide shed models can be extended in 2.5-foot increments if you need a longer length.

Wall, Roof, and Floor Construction

Walls, roof, and floors are made with high-density polyethylene (HDPE) plastic. This type of plastic is resistant to fading, cracking. or peeling unlike traditional plastics. They are also weather resistant and will not warp in the rain like wood sheds. The walls of the shed are double-walled HDPE plastic providing extra rigidity and support to the shed structure - measure about 1-inch thick. The floor features an impressioned, slip-resistant mold. Roof panels feature and simulated-shingle design.

Doors and Roof Trusses

Doors and roof trusses of this Lifetime storage building feature powder-coated steel. The powder coating on the steel helps the steel resist rusting, giving your shed structure a longer life. The doors are reinforced along the frame to provide added strength and rigidity to your doors.

Low Maintenance Required for Lifetime Sheds

HDPE plastic, unlike wood, does not need to be repainted. Thus, Lifetime shed products rarely need any sort of maintenance. HDPE is stain resistant, typically only needing soap and water to clean up stains.
