Large 15 ft artificial trees commonly use PVC branch tips combined with metal components for the frame and hinges. Product descriptions also mention metal wiring and, in some models, glass or wired bulbs used in the lighting assemblies.
Many listings include a supporting base or stand with the tree. Descriptions frequently specify metal tree stands or metal bases as the included support for these tall models.
Listings consistently show a 15-foot tree height. Base diameters vary by model — many show base widths around 68–74 inches, while some commercial or fuller models list larger base diameters (for example a model listing an 8.5-foot base diameter).
Tip counts indicate how dense or full a tree will look — counts in listings vary widely (examples include 4,188; 7,091; and 7,449 tips). Hinged-branch construction is commonly used with higher tip counts to help achieve a full appearance while simplifying setup.
