Materials Used in Lifetime Buildings

High-Density Polyethylene

Lifetime manufacture plastic buildings  constructed of high-density polyethylene (HDPE). This is Lifetime’s material of choice because HDPE is known for its strength, durability, and resistance to chemicals and moisture. It is what makes Lifetime’s garden buildings lightweight, while maintaining superior strength and durability. Lifetime’s buildings are UV-protected, resistant to extreme heat and cold, and will not fade or crack. They are stain resistant, easy to clean, and low maintenance.


UV-Inhibitors are a very important component of Lifetime’s garden buildings. The high-density polyethylene (HDPE) is a US Food and Drug Administration (FDA) grade plastic that includes premiere UV-Inhibitors and light fast pigments to make these buildings very resistant to heat and extended exposure to the harmful UV rays of the sun. This UV protection is the best on the market and ensures that our products will not crack, chip, or peel.

Environmentally Friendly

High-density polyethylene (HDPE) is one of the most environmentally preferred plastics because it is 100% recyclable, does not create harmful emissions during production and does not leak toxic chemicals into soil or water.

Powder Coated Steel

Lifetime’s rust-resistant, powder-coated finish makes these plastic buildings resistant to chips, scratches, and regular wear-and-tear. Powder-coating prevents rusting, corrosion and protects steel parts from UV-damage, making it a great all-weather finish.
