Item No.: ES1806DTPSATURI Endura-Stone Round Tapered Fiberglass (FRP) Columns are a durable, low-maintenance alternative to traditional wood columns. They offer high strength, protection against the elements, and timeless style. 

Overview

Endura-Stone columns offer the classic look of architectural wood without the maintenance, weight, or cost. Inspired by ancient Greek and Roman design, they feature historically accurate profiles and an entasis taper (a subtle curve that creates the illusion of straightness and strength). Made from fiberglass-reinforced polymer (FRP), they’re stronger lb for lb than concrete, steel, or aluminum, offering reliable performance in both decorative and load-bearing applications.

Built for long-term durability, Endura-Stone resists warping, moisture, rot, and insect damage, making it ideal for even the harshest environments. The low-maintenance, paintable surface resists peeling, fading, and cracking to maintain a clean, crisp look. Whether you’re framing a front entry or enhancing interiors spaces, these columns provide timeless style with the authentic feel of stone or wood not a thin metal or plastic.

Available in multiple plan types, including load-bearing options for concentric and eccentric loads (Plan Type A only). Trim-to-fit flexibility suits both indoor and outdoor use across residential and commercial applications. Backed by a lifetime warranty, they’re a reliable solution for builders, architects, and homeowners. Tapered columns come in both fluted and non-fluted styles.
