Hengshui Ruibin New Materials LLC, established in 2019 with a dedicated team of 101–200 skilled employees and a modern factory spanning 1,000–3,000 square meters, specializes in manufacturing high-performance FRP profiles. Our Corrosion Resistant FRP Rectangular Tube 150x75mm Weight 0.6kg/m for Marine Applications represents the perfect balance of durability, lightweight design, and anti-corrosion properties. Designed specifically for harsh marine environments, this rectangular tube resists saltwater, UV radiation, and chemicals, offering a long service life without rust or rot. Whether you need structural supports, handrails, or framework on boats, docks, or offshore platforms, this FRP tube delivers unmatched reliability and cost-efficiency.
Key Features and Technical Specifications
- Exceptional Corrosion Resistance: Made from premium-grade fiberglass reinforced polyester resin, this tube withstands continuous exposure to seawater, acidic fumes, and industrial chemicals. No pitting, no galvanic corrosion – ideal for marine and chemical plants.
- Lightweight yet Strong: At only 0.6 kg/m, the 150x75mm profile offers a high strength-to-weight ratio. It reduces structural load and simplifies installation, minimizing labor and transportation costs.
- Non-Conductive & Non-Magnetic: FRP is electrically insulating and non-magnetic, making it safe for use near sensitive electronics or in explosive environments.
- UV Stabilized: The resin formulation includes UV inhibitors to prevent degradation from sunlight, ensuring color stability and mechanical integrity over decades of outdoor service.
- Customizable Sizes & Colors: Available in standard 6-meter lengths, we can cut to your required dimensions. Color options include grey, yellow, orange, or any custom color to meet safety or aesthetic needs.
- Easy to Fabricate: Can be cut, drilled, and machined with standard tools. It can be bonded or mechanically fastened, offering flexibility in design.
- Low Thermal Conductivity: FRP does not transfer heat or cold, reducing condensation and improving energy efficiency in applications like cooling towers or pipelines.

Benefits for Your Applications
- Marine Structures: Ideal for dock fenders, boat railings, gangways, and underwater support frames. No need for painting or maintenance – simply install and forget.
- Chemical Processing: Use in cooling towers, scrubbers, and ducting where steel would corrode quickly. FRP resists acids, alkalis, and solvents.
- Infrastructure: Bridges, walkways, and platform gratings benefit from the low weight and high strength. The non-slip surface option is available.
- Electrical Safety: Perfect for cable trays, ladder rails, and enclosures in substations or power plants where non-conductivity is critical.
- Cost Savings: Lower installation costs due to light weight, zero corrosion-related replacements, and minimal maintenance. The total lifecycle cost is significantly lower than aluminum or stainless steel.

Frequently Asked Questions
Q1: What is the maximum length available for this rectangular tube?
Standard length is 6 meters, but we can produce custom lengths up to 12 meters or cut to your specified dimensions. Please discuss with our sales team.
Q2: Can this FRP tube withstand direct sunlight and saltwater without fading?
Yes. The UV-stabilized polyester resin prevents color fading and surface degradation. For extreme UV exposure, we recommend adding a gel coat layer for enhanced protection. The material is inherently resistant to saltwater corrosion.
Q3: What is the weight tolerance per meter?
Our manufacturing tolerance for weight is ±5%. The nominal 0.6 kg/m is an average value; actual weight may vary slightly depending on resin and glass content adjustments.
Q4: Can I drill holes or cut the tube on site?
Absolutely. FRP can be cut using a hacksaw or abrasive saw and drilled with standard carbide-tipped drills. Always wear respiratory protection when machining to avoid dust inhalation.
Q5: Is this product fire-resistant?
Polyester resin FRP is combustible. However, we can incorporate flame-retardant additives (e.g., halogen-free) to meet specific fire codes. Please inquire about our fire-retardant grade options.
Q6: Do you offer any warranty?
We provide a standard warranty against manufacturing defects. The product's lifespan in marine environments typically exceeds 20 years under normal conditions. Contact us for detailed warranty terms.
Q7: How does the price compare to stainless steel or aluminum?
FRP is generally more cost-effective than stainless steel and comparable to aluminum when considering total lifecycle costs (no painting, no corrosion protection, no replacement). Our pricing is highly competitive.
Q8: Can I get a sample before placing a bulk order?
Yes. Sample orders are accepted. We can provide a small cut piece (e.g., 30cm length) for testing. Sample cost and shipping can be deducted from your first bulk order.
