Fiberglass angle is a structural shape made of fiberglass reinforced plastic (FRP), formed at a 90-degree bend and used across applications that call for strength, corrosion resistance, and light weight. It is a common substitute for metal angle thanks to its longer life and lower upkeep costs.

Benefits of Fiberglass Angles

Compared with metal angle, fiberglass angle brings several advantages:

Corrosion Resistance: it holds up in harsh environments — chemical exposure, salt water, humidity, and temperature extremes — without rusting, rotting, or corroding, and it resists insects and fungi as well.

Strength and Durability: high tensile and flexural strength let it handle heavy loads and impacts, and it resists fatigue, cracking, and deformation.

Light Weight: being much lighter than metal angle cuts transportation and installation costs while improving overall structural performance and efficiency.

Electrical Insulation: since it does not conduct electricity, it is safe for electrical applications, with strong arc and track resistance that helps prevent electric discharge and fire hazards.

Design Flexibility: it is easily fabricated, cut, drilled, and joined into different shapes and sizes, and can be customized with different colors, finishes, and resin types to meet specific requirements.

Applications of Fiberglass Angles

Fiberglass angle serves a wide range of structural applications, including:

Building and Construction: framing members, supports, braces, trusses, columns, beams, railings, stairs, platforms, and ladders, as well as architectural features like decorative moldings, trimmings, and cornices.

Industrial and Chemical: pipe supports, cable trays, ducts, tanks, vessels, filters, scrubbers, and separators, plus equipment enclosures, housings, cabinets, and racks.

Marine and Offshore: boat hulls, decks, masts, spars, bulkheads, and hatches, along with offshore platforms, rigs, barges, docks, and piers.

Electrical and Electronic: arc barriers, switch mounts, circuit breakers, and other electrical equipment components, as well as antenna towers and radomes.

Targeted Product FAQ

Q1: What sizes of fiberglass angles are available?

A1: A range of standard leg lengths and thicknesses are available, with custom sizes on request — see the Customized Service options above.

Q2: Are fiberglass angles as strong as steel angles?

A2: For most bracing, framing, and support applications fiberglass angles provide sufficient strength at a much lower weight — share your load and span requirements and we can help confirm suitability.

Q3: What environments are fiberglass angles best suited for?

A3: Chemical processing plants, wastewater treatment facilities, marine structures, and any application where metal angles would corrode or require frequent recoating.

Q4: Can fiberglass angles be cut and drilled on-site?

A4: Yes, standard cutting and drilling tools work well; we recommend carbide-tipped blades/bits for a clean cut and to reduce tool wear.

Q5: What colors and surface finishes are available?

A5: Standard and custom colors can be pigmented into the resin during pultrusion, and a smooth surface veil is available for a splinter-free, easy-to-clean finish.
