Materials
Tree houses can be built with a wide range of materials. Wood is commonly used for structural parts and cladding due to its strength, light weight and low cost. Steel is used for brackets, cables and bolts, including specialized tree bolts capable of supporting up to 6,000 pounds (2,700 kg). Builders of tree houses sometimes use recycled materials or parts, such as reclaimed window frames, doors and used lumber. Fabrics can be used to produce non-rigid temporary structures that are more like tree tents than tree houses.

Famous quotes containing the word materials:
“Young children learn in a different manner from that of older children and adults, yet we can teach them many things if we adapt our materials and mode of instruction to their level of ability. But we miseducate young children when we assume that their learning abilities are comparable to those of older children and that they can be taught with materials and with the same instructional procedures appropriate to school-age children.”
—David Elkind (20th century)
“Kicking his mother until she let go of his soul
Has given his a healthy appetite: clearly, her role
In the New Order must be
To supply and deliver his raw materials free;”
—W.H. (Wystan Hugh)
“Our job is now clear. All Americans must be prepared to make, on a 24 hour schedule, every war weapon possible and the war factory line will use men and materials which will bring, the war effort to every man, woman, and child in America. All one hundred thirty million of us will be needed to answer the sunrise stealth of the Sabbath Day Assassins.”
—Lyndon Baines Johnson (1908–1973)
