Fun facts about TREX CO INC

Quirks, history, and lore behind TREX — the kind of stuff that makes a stock memorable.

1
The Basics
U.S. building products company · mid-cap · listed on the NYSE · headquartered in Virginia.
2
The Numbers
Annual revenue in the range of $1 billion, with margins that make traditional lumber companies deeply jealous — gross margins above 40% in good years.
3
The History
Founded in the 1990s, it was a pioneer in turning recycled plastic and wood fiber into a product most people assumed could only come from a tree.
4
The Secret
Its core product never needs staining, sealing, or painting — a major selling point over real wood, which rots, splinters, and demands weekend-ruining maintenance.
5
The Lore
The company diverted billions of pounds of plastic film and reclaimed wood from landfills to make its products — so your backyard upgrade is technically a recycling project.
6
The Giveaway
It is the dominant brand in composite decking — if an American has a beautiful low-maintenance deck out back, there's a very good chance it came from this company.
