Hengshui Ruibin New Materials LLC is proud to introduce our premium Pultruded Fiberglass I-Beam Profiles, engineered with an advanced IP65 waterproof coating and a broad operating temperature range of -50°C to 120°C. As a dedicated manufacturer since 2019, we combine years of pultrusion expertise with a modern 1,000–3,000 m² factory and a skilled team of 101–200 professionals. These I-beams deliver exceptional strength-to-weight ratio, corrosion resistance, and dimensional stability—making them the ideal choice for demanding environments where traditional steel or wood fail.
Our pultruded fiberglass I-beam profiles are produced through a continuous process that ensures consistent cross‑section and superior mechanical properties. The IP65 waterproof coating provides reliable protection against water ingress, dust, and moisture, while the temperature tolerance from -50°C to 120°C guarantees performance in extreme climates. Whether you need structural support for chemical plants, marine piers, bridges, or building frameworks, these profiles offer a lightweight yet robust alternative that reduces installation costs and maintenance burdens.
Key Features & Technical Specifications
- High Corrosion Resistance – Impervious to saltwater, acids, alkalis, and most industrial chemicals.
- IP65 Waterproof Coating – Fully sealed surface prevents moisture penetration and extends service life.
- Wide Temperature Range – Reliable performance from -50°C to 120°C without cracking or delamination.
- Lightweight Design – Up to 70% lighter than steel, reducing transportation and handling costs.
- Excellent Electrical Insulation – Non‑conductive and non‑magnetic, safe for electrical environments.
- UV‑Resistant Finish – Gel coat or paint options protect against sun degradation.
- Customizable Dimensions – Available in various flange widths, web heights, and thicknesses per your requirements.
- Low Thermal Conductivity – Minimizes thermal bridging in building applications.

- Non‑Conductive & Non‑Magnetic – Safe for electrical substations, MRI rooms, and sensitive electronics.
- Environmentally Friendly – Long lifespan reduces replacement waste; material is recyclable.
Our I‑beam profiles serve a wide range of industries: construction (platforms, walkways), marine (dock fenders, boat hull supports), infrastructure (bridge components, tunnel supports), chemical processing (pipe racks, tank supports), and renewable energy (solar panel structures). With annual export value between US$2.5 million and US$5 million, we have shipped to markets across North America, South America, Europe, Southeast Asia, Africa, the Middle East, and Oceania. Our factory is located in Hengshui, Hebei, China, and we ship via Port of Tianjin or Port of Qingdao.
Trust and Reliability – We maintain strict quality control throughout production, and our products have received third‑party certifications (details available upon request). Our team of 101–200 experienced workers ensures every profile meets your exact specifications. We also offer customized sizes, colors, and additional treatments (e.g., fire‑retardant resin, anti‑static coating) to suit your project needs. Contact us today for a quote or technical consultation – let our pultruded fiberglass I-beams build a stronger, lighter, and more durable future for your infrastructure.
Frequently Asked Questions (FAQ)
-
What is the load‑bearing capacity of your I-beams?
Load capacity depends on size and span. Please provide your design parameters, and we will calculate the appropriate profile. Typically, a 150mm x 75mm I-beam can support distributed loads exceeding 500 kg/m. -
Are these beams suitable for outdoor use in extreme cold?
Absolutely. With a temperature range of -50°C to +120°C and UV‑resistant coating, they perform excellently in arctic or desert climates without becoming brittle or degrading. -
Can I cut or drill holes in the beams on site?
Yes. Fiberglass composites can be cut, drilled, and machined using standard carbide‑tipped tools. We recommend sealing any exposed cut edges with the provided gel coat to maintain waterproof integrity. -
Do you provide custom colors or special coatings?
Yes, we offer a variety of colors and can apply additional coatings such as anti‑static, fire‑retardant, or enhanced UV protection upon request. -
What is the typical lead time for an order?
Standard orders (6m lengths, common sizes) take 10–15 working days after confirmation. Custom profiles may require 20–30 days depending on complexity. -
How do your beams compare to steel in terms of weight and strength?
Fiberglass I-beams are approximately 70% lighter than steel and offer comparable strength for many applications. Their specific strength (strength‑to‑weight ratio) is often higher than steel. -
Do you have any certifications for fire resistance?
We can produce beams with flame‑retardant resin meeting Class B1 (European standard) or other national standards. Please specify your requirement during inquiry. -
What is the warranty period?
We provide a standard 12‑month warranty against manufacturing defects. Extended warranty options are available for bulk orders.
