Building Material Black Carbon Steel Square Tube

We adhere to the concept of green development, continuously accelerate the pace of structural adjustment, and optimize the development of environmentally friendly Carbon Tube, Fiberglass Pole, Endzone Camera System. We are people-oriented, capital-based, technology-based, market-oriented, creating a good internal and external environment, maximizing the talents and enthusiasm of our employees, and keeping the company vigorous and dynamic. We insist on 'Quality First, Reputation First and Customer First'. Our company is based on the principle of customer first and win-win cooperation, and we have established many win-win customer relationships and multiple sales and service outlets. Our company has outstanding technology research and development and production capacity, as well as keen market research and judgment, advanced marketing concept.

Xinbo Composites customizes carbon tube round tubing for many applications. Available in carbon fiber tubes in roll wrapped, filament winding processes, custom sizes available upon request, diameters from 5mm to 500mm, length up to 6000mm.

Carbon Tubes are manufactured using multiple layers of prepreg carbon fiber materials. The number of layers allows us to vary the orientation of the fibers throughout the thickness, creating high-performance products according to per client's requirements.

Carbon Tube Round Tubing Advantages

1. Exceptional Specific Strength and Stiffness
Carbon fiber has one of the highest strength-to-weight and stiffness-to-weight ratios of any material, which is 5 times stronger than steel and 2 times stiffer, and also 70% lighter. It is also stronger and stiffer than aluminum and titanium at a fraction of the weight.

2. Low Density (Extreme Lightweight)
Density of ~1.6 g/cm³, compared to 7.8 g/cm³ for steel and 2.7 g/cm³ for aluminum. Reduces mass, inertia, and energy consumption. In vehicles, this improves acceleration, braking, handling, and fuel efficiency. In robotic arms and industrial rollers, faster, more precise movement with less powerful motors.

3. High Fatigue Resistance
Excellent resistance to cyclic loading and metal fatigue. It does not develop stress concentrators like microcracks in metals.
Ideal for dynamic, high-stress components like aircraft wings, idler rollers, and sporting equipment

4. Corrosion and Chemical Resistance
Inert to most chemical and environmental degradation. It does not rust, oxidize, or corrode like metals. Perfect for harsh environments, such as chemical processing equipment, offshore oil & gas, marine vessels, and infrastructure where salt, acids, or moisture are present. Reduces maintenance and lifetime cost.

5. Excellent Durability and Longevity
When properly designed and protected from UV, it offers an extremely long service life with minimal property degradation.
Creates durable, low-maintenance products with longer usable lifespans, offsetting higher initial costs.

Carbon Tube Round Tubing Process

1. Wrapped onto a mandrel in multiple layers and angles

2. Externally pressurized with transparent PP tape

3. Heat-cured to solidify

4. After curing, the solid composite demolded from the mandrel as a tube

Carbon Tube Round Tubing with Multi Layers

0° Fibers maximize bending stiffness.

90° Fibers maximize crushing stiffness and generally assist in overall tube strength.

45° Fibers maximize torsional stiffness.
