Co-extruded WPC beams for outdoor spaces, in three sizes and one length. Get the look of wood on pergolas, privacy screens and facades.
Extrutech decorative beams are hollow, wood-look WPC beams built for outdoor spaces. Use them to dress up a facade. Divide two outdoor areas with a wall of beams that lets air and light through (a privacy screen). Or build an open roof of beams set side by side, as close together or as far apart as you want (a pergola). Put them in front of a wall or window for partial shade that doesn't close in the space. They come in three sizes and are built to stay out in the elements.

These beams are a decorative cover and are not load-bearing. Every project needs an internal frame of steel, steel tubing or treated lumber to carry the weight. The WPC beam wraps that frame and gives it the look of wood.

All three beams are 9.8 ft (300 cm) long. What changes is the cross-section—the width and height of the beam.

A beam pergola turns a patio that gets full sun into a shaded spot without roofing it over. The beams filter the light the way a tree does, and the space stays open. Add lights, curtains or a shade sail to the frame later, and the home finally gets the outdoor room it was missing.
A privacy screen takes care of the view. It blocks sight lines from the street or the neighbors and still lets air and light through. You don't need to enclose the whole perimeter. Just screen the side that faces out and keep the view you want.


From a backyard corner to a hotel pool: the same beam, sized to fit the space.
All three beams are the same length and install the same way. Which one you use depends on the scale of the space—how thick the beams need to look from below to keep the pergola or screen in proportion.
For privacy screens, outdoor dividers and residential pergolas that need visual rhythm without bulk. It's the lightest of the three, which helps when your crew is working overhead.
When the 6x4 looks too thin and the 12x6 looks oversized, the 10x5 hits the sweet spot. Use it for pergolas over large patios, partially covered carports and common areas in residential developments—places where the pergola needs to look substantial without overpowering the space.
On a large pergola—a hotel terrace, an outdoor lobby—the beams are the first thing people see, and they set the tone for the whole place. A thin beam gets lost at that scale. The 12x6 stays in proportion and holds its own. For large projects we also make custom lengths, so there are fewer cuts and less waste on site.
All three sizes use the same system. The frame that carries the load is steel—square or rectangular tubing—or treated lumber, and the WPC beam covers it as the finished face. From the ground, the pergola looks like it's built with wood beams. Inside, it has a frame designed to handle wind and its own weight.
For a home pergola, the steel fabricator builds the frame from steel tubing, and the 6x4 or 10x5 goes over each member. For large-scale projects, an engineer designs the frame—W-beams, HSS or trusses—and the 12x6 wraps it. Either way, end caps close off the beam ends for a clean finish and protect the cut ends from the weather over the years.



Made in Monterrey, Mexico, and delivered to your yard or job site anywhere in Texas.
Natural wood outdoors needs stain or sealer every 12 to 18 months. On a hotel or plaza pergola with dozens of beams, that cost comes back year after year and adds up.
WPC beams never need stain, sealer or paint—just a pressure wash with mild soap. The Max Shield cap is co-extruded with the beam (it isn't paint), and we get the matte look without brushing, so the cap is never worn down to create it. Our in-house quality lab tests production samples of every size.
All three beams come in the same 12 colors as Wall Cladding and Grooved Panel, and Solid Deck comes in those same 12. A project with decking underfoot, cladding on the ceiling and beams on the pergola can use one color throughout—say, Teka—or mix colors by design.
We make everything in the same plant with the same formula, so the color matches from piece to piece and batch to batch. Reorder next season and it still matches, and you never have to eyeball wood from different suppliers. See the 12 colors →





Vertical or horizontal
Set vertically, a screen makes a facade look taller. Set horizontally, it makes the space look wider.
