Pultruded FRP Angle Bar

Pultruded FRP angle bar is L-shaped fiberglass composite divided into equal leg and unequal leg types via continuous pultrusion. The 90° cross-section delivers stable corner support, lightweight yet high-strength, fully rust-proof and electrically insulated with over 20 years maintenance-free service life. Processable with common tools, customizable on size, thickness, color and fire resistance. It serves as core connecting fittings matched with FRP tubular profiles for chemical, marine, power, construction and agricultural structural projects.

Product Introduction

FAQ

Pultruded FRP angle bar (also known as fiberglass L-profile / fiberglass angle iron) is an L-shaped structural composite manufactured via continuous pultrusion molding. Continuous E-glass roving and surface veil are fully impregnated with thermosetting resin, then pulled through 90° heating molds for integral curing.

We supply two main types: equal leg FRP angle (two sides same width) and unequal leg FRP angle (two sides different width). As a superior replacement for steel and aluminum angle iron, it integrates light weight, anti-corrosion and insulating performance. All products meet ISO9001 and EN13706 standards, with regular sizes in stock; leg width, thickness, resin and color are fully customizable.

Complete Technical Specifications:

1. Dimension Range

Equal leg size: 20mm×20mm ~ 150mm×150mm

Unequal leg size: 25mm×50mm, 30mm×60mm, 40mm×80mm, custom asymmetric sizes

Thickness: 3mm ~ 12mm

Standard single length: 6m; arbitrary custom cutting length supported

Inch-sized angles available for North American customers

2. Optional Resin Matrix

General Polyester: Cost-effective for regular indoor & outdoor construction frames

Vinyl Ester: Super anti-corrosion grade for marine, chemical and sewage projects

Epoxy: Higher mechanical strength, dedicated to high-standard electrical insulation structures

3. Standard Color Choices

Safety yellow, white, light grey, dark grey, green, red; custom color matching supported

4. Mechanical Reference Data

Density: 1.8–2.0 g/cm³ | Tensile Strength ≥350MPa | Flexural Strength ≥450MPa

Certifications: ISO9001, EN13706, UL94 flame retardant certificate optional

Core Competitive Advantages:

1. L-Shape Right-angle Structural Support

Built-in 90° vertical cross-section, perfect for corner connection, frame reinforcement and load-bearing brackets. It evenly disperses corner stress to avoid local deformation, widely used for assembling all kinds of composite frame systems matched with FRP square/rectangular/round tubes. Only 1/4 density of steel, easy manual transport and installation without heavy lifting equipment.

2. Outstanding Corrosion & UV Aging Resistance

Zero rust, oxidation or rotting. Resist seawater salt spray, acids, alkalis and most industrial chemical solvents. Outer gel-coat layer blocks UV damage, no fading or surface cracking under long-term outdoor exposure, ideal for coastal, chemical, wastewater and aquaculture harsh environments.

3. Full Electrical & Thermal Insulation

Non-conductive and non-magnetic, completely eliminate electric leakage and arc flash risks. Low thermal conductivity prevents heat transmission, the ideal structural connector for substations, cable brackets and electrical equipment frames.

4. Zero Maintenance & Long Service Life

Integral pigmented resin body requires no periodic painting, galvanizing or anti-rust coating. Stable mechanical performance for over 20 years outdoors, greatly cutting long-term project maintenance costs compared with metal angles.

5. Easy Machining & Rich Custom Options

Can be cut, drilled, bolted and bonded with standard woodworking tools, no welding needed. Multiple leg sizes, wall thicknesses, solid colors and flame-retardant resin grades available on demand.

6. Optional UL94 Flame Retardant Grade

Vinyl ester fire-retardant FRP angle releases low smoke and no molten drips, compliant with fire safety codes for factories, public buildings and power facilities.

Wide Application Scenarios:

1. Chemical & Wastewater Treatment: Platform bracket reinforcement, cooling tower frame connectors, tank corner supports

2. Marine & Coastal Engineering: Dock railing fixing parts, seaside walkway corner braces, offshore equipment supports

3. Power & New Energy: Substation insulation cross arm connectors, solar PV frame corner fittings, cable channel brackets

4. Construction & Public Facilities: Stair frame reinforcement, billboard stand corner parts, safety handrail connecting pieces

5. Agriculture & Horticulture: Greenhouse frame corner bracing, livestock farm partition fixing angles

6. Industrial Workshop: Equipment frame connectors, safety barrier corner supports, platform edge reinforcement
