Before You Buy Composite, See What’s Actually Inside It.

Composite Looks Solid. Its Recipe Tells the Real Story.

“Composite” is a broad category, not one universal formula. Many exterior composite boards are wood-plastic composites, often called WPC. They combine wood flour or cellulose fibers with thermoplastic polymers, pigments, stabilizers and other additives. Ratios, cap layers and manufacturing methods vary.

That mixture can offer a consistent wood-inspired surface and avoid some maintenance associated with unfinished natural wood. It does not turn composite into metal, and it should not be described as a noncombustible material without product-specific test evidence.

Why Composition Matters

The material recipe influences fire behavior, heat response, moisture movement, surface weathering, fastener performance, weight and repair options. Two composite products may perform differently, which is why buyers should request the technical data for the exact board and complete fence assembly.

Aluminum Starts Somewhere Else

Aluglobus begins with structural aluminum extrusions. The profiles create posts, rails, frames and infill, then receive an architectural exterior finish. The wood appearance is on the finish. The structure underneath stays aluminum.

A Strong Material Can Still Become a Weak Fence.

Fence performance depends on the full load path. Wind pushes on slats and privacy infill. The rails transfer that load into posts. Posts transfer it into footings, base plates, walls or another approved support. Every connection matters.

Composite boards may require manufacturer-specific spacing, support intervals and allowances for expansion. Aluminum extrusions also require correct spans, fasteners, post spacing and thermal allowances. Neither system should be installed from appearance alone.

Questions to Resolve Before Ordering

Confirm total linear footage, finished height, property-line conditions, slope, steps, bottom clearance, privacy level, slat direction, gaps, post mounting, soil or concrete conditions, wind exposure, gates and local permit requirements. For wall-mounted work, confirm whether the existing structure can accept the required loads.

Aluglobus can supply systems nationwide, while installation availability depends on location and project scope. Contractors should verify site measurements and code requirements before fabrication.
