We take pride in introducing our pultruded fiberglass channel profile, measuring 80mm × 40mm × 5mm, crafted by Hengshui Ruibin New Materials LLC. As a professional manufacturer with an experienced team of 101-200 employees, we have been dedicated to producing high-performance composite sections since 2019. This lightweight yet robust structural channel offers a maximum tensile strength of 300 MPa, making it an excellent alternative to traditional steel and aluminum sections in corrosive or electrically sensitive environments.
Product Overview – The 80x40x5mm channel is manufactured using the pultrusion process, a continuous production method that combines continuous glass fiber roving and thermosetting resin under controlled tension and heat. The result is a profile with uniform cross-sectional geometry, excellent mechanical properties, and a smooth or textured surface finish. The dimensions of the channel – 80mm width, 40mm height, and 5mm wall thickness – are carefully designed to provide high stiffness and load-carrying capability while maintaining a low overall mass. This product is supplied in standard lengths of 6m and 12m, and can be cut to exact customer specifications upon request.
Key Features
- High Tensile Strength: The channel achieves a maximum tensile strength of 300 MPa, enabling secure structural support in both static and dynamic load applications.
- Lightweight Composite Construction: With a density of approximately 1.8 g/cm³, the profile is about 75% lighter than steel, reducing dead loads on supporting structures and easing manual handling.
- Corrosion Resistance: Resistant to moisture, chemicals, salt spray, and atmospheric agents, the fiberglass matrix eliminates the need for rust-inhibiting coatings and routine repainting.
- Electrical Insulation: The non-conductive nature of the composite protects workers and equipment in electrical environments, such as cable trays, switchgear enclosures, and power plants.
- Thermal Insulation: Unlike metals, this composite section does not form thermal bridges, improving energy efficiency in building envelopes and reducing condensation issues.
- Dimensional Stability: Low thermal expansion and minimal warping ensure that the channel maintains its shape and performance over a wide range of operating temperatures.
- Environmental Resistance: UV-stabilized resin systems provide dependable outdoor performance without degradation, even under prolonged sunlight exposure.
- Customizable Options: Length, color, and surface texture can be tailored to meet project-specific requirements, with quick turnaround times.
Technical Specifications
The following table summarizes the main technical parameters of the pultruded fiberglass channel 80x40x5mm.
| Parameter | Value |
| Product Type | Pultruded Fiberglass Channel |
| Cross-Section Dimensions | 80mm (W) x 40mm (H) x 5mm (T) |
| Maximum Tensile Strength | 300 MPa |
| Material | Glass Fiber Reinforced Polymer (GFRP) |
| Density | Approx. 1.8 g/cm³ |
| Standard Length | 6m, 12m, or custom |
| Color | Black, gray, green, or custom |
| Surface Finish | Smooth or textured |

The mechanical properties listed above are derived from tensile testing conducted in accordance with recognized test methods. The cross-sectional profile is optimized to provide maximum bending resistance in the vertical plane, while the 5mm wall thickness adds robustness in the flanges and web. For special load-bearing requirements, structural calculations can be provided on request to assist design engineers in selecting the proper profile for their applications.
Benefits to Customers
Switching from traditional metal profiles to this fiberglass composite channel offers several tangible benefits:
- Cost Savings: Lower weight means reduced shipping costs and simpler installation equipment, while no paint or protective coating is required over its service life.
- Safety: The non-conductive and non-slip features (when textured) enhance worker safety, especially in electrical or slippery environments.
- Longevity: The corrosion-resistant nature significantly extends service life in harsh environments, minimizing replacement and maintenance expenses.
- Design Flexibility: Pultruded sections can be easily cut, drilled, and machined with standard tools, facilitating on-site adjustments and custom fabrication.
- Eco-Friendliness: The resin and glass fiber system is produced with low energy consumption and is recyclable in specialized facilities, supporting sustainability goals.
Applications
This channel profile is widely used in many sectors:
- Construction: Structural frames, walkways, stair treads, handrails, and support beams.
- Electrical: Cable trays, busbar supports, insulating stands, and equipment mounting rails.
- Chemical & Corrosive Environments: Platforms, ladder systems, and tank supports that resist acids, alkalis, and solvents.
- Transportation: Components for truck bodies, trailers, and public transportation systems where weight reduction is key.
- Marine & Offshore: Dock structures, offshore platform grating, and saltwater-exposed frameworks.
- Renewable Energy: Mounting structures for solar panels and components for wind turbine nacelles.

Frequently Asked Questions
-
Q: What is the maximum length you can produce?
A: We can supply in standard lengths of 6m and 12m. For special orders, we can produce custom lengths according to your drawings or requirements, generally up to 8m or 12m. Please confirm with our sales team for exact capabilities. -
Q: Can this fiberglass channel be used outdoors?
A: Yes. The UV-resistant resin system and corrosion-resistant fibers make it suitable for long-term outdoor use without degradation. It withstands rain, sunlight, and temperature variations effectively. -
Q: Is sample available before bulk order?
A: Yes, we can provide samples for evaluation. Typically, samples are available from stock for standard sizes, and the cost can be covered by a small freight charge. Once an order is placed, the sample cost is often deducted from the total amount. -
Q: How do you pack the profiles for export shipping?
A: We package profiles in bundles with protective film or plastic wrapping, then use wooden pallets or steel-framed crates, depending on length and quantity. This ensures damage-free transit. -
Q: Can you customize the cross-section dimensions?
A: While the tooling is for standard 80x40x5mm, we can accommodate some variations such as wall thickness and length according to your project needs. For completely different cross-sections, we can discuss custom tooling development with a minimum quantity commitment. -
Q: What is the lead time for large orders?
A: Typical lead time is about 10-20 days after confirmation of specifications and payment, depending on quantity. For regular mass production, we can schedule weekly production slots. Please contact us for a detailed delivery plan. -
Q: Is the product suitable for load-bearing structures?
A: Yes, with a maximum tensile strength of 300 MPa and good flexural properties, the channel can support moderate loads. For critical structural applications, engineering calculations are available on request to confirm safety.
