When shopping for 300g Unidirectional Carbon Fiber Fabric, look no further than China's JUN TENG, a professional carbon fiber direct-sale manufacturer with 18 years of deep industry experience. Our products comply with national standards, are woven from T700 raw silk, and feature strong load-bearing capacity, corrosion resistance, and durability, making them suitable for heavy-duty beam columns and bridge reinforcement. We support both wholesale and retail sales, with rigorous quality inspection backed by authoritative reports.
The specifications of reinforced carbon cloth on the market are diverse and complex, making it difficult for most purchasers to distinguish between the applicable boundaries of 200g and 300g carbon cloth. Choosing the wrong material can easily lead to engineering hazards such as insufficient load-bearing capacity and soaring costs due to multi-layer bonding.
JUN TENG has been deeply involved in the reinforcement material industry for 18 years. Relying on its own research and development laboratory and standardized weaving production line, it has precisely crafted this 300g Unidirectional Carbon Fiber Fabric, specifically designed for construction and bridge projects with significantly increased loads and stringent load-bearing requirements.
The entire production process of the product follows national reinforcement standards GB50367-2013 and GB50728-2011. Unlike inferior carbon cloth from small workshops that lack testing and falsely label parameters, our company retains batch samples for each roll of 300g carbon cloth and issues a third-party test report stamped with a CMA seal for each batch.
All parameters are measured and publicly disclosed, allowing purchasers to directly use them for supervision and inspection, project archiving, and to avoid engineering acceptance risks from the source. It is the preferred heavy-duty reinforcement material recommended by design institutes and reinforcement construction companies.
Product specifications and differentiated design logic
Many customers are confused about the scenarios where 300g Unidirectional Carbon Fiber Fabric must be used. The core difference lies in the fiber filling amount and unit load-bearing capacity: 300g represents a net weight of 300g per square meter of carbon fabric. Compared to 200g carbon fabric, the carbon fiber content is increased by 50%, and the tensile performance of a single layer is significantly improved. There is no need for multiple layers to be stacked and pasted, reducing costs related to glue, labor, and construction period. The raw material is selected from brand-new T700 grade 12K PAN-based carbon fiber precursor, without mixing recycled waste fibers or chopped fibers. The unidirectional centralized weaving process is adopted, with 95% of the carbon fibers uniformly arranged along the stress direction, and only thin hot-melt yarn is used for lateral restraint, ensuring no dispersion of tensile force. The fully automatic constant temperature weaving equipment strictly controls the thickness tolerance, resulting in a fabric surface free from broken fibers, fuzzing, and yarn deviation issues. It is soft and easy to fit various irregular components such as beams, columns, curved piers, and tunnel walls.

Core Advantages of Targeted Engineering
1. Single-layer meets heavy-load design, significantly reducing comprehensive construction costs. For projects with large load increments such as adding floors to factories, heavy equipment foundations, and large-span bridges, 200g carbon cloth often requires 2 to 3 layers of bonding. However, 300g Unidirectional Carbon Fiber Fabric can achieve the design load-bearing capacity with a single layer, reducing construction processes, glue consumables, and labor costs, and shortening the construction period by more than half.
2. Thin and lightweight, without disrupting the original building's load-bearing system. Carbon fiber has a self-weight only 1/4 that of steel, and the total thickness after bonding is less than 3mm, which will not increase the beam and column cross-section or occupy indoor ceiling height. Compared to steel bonding and cross-section enlargement reinforcement schemes, it will not add additional permanent loads to the original structure, making it suitable for retrofitting old buildings and load-bearing sensitive structures.
3. All-weather long-lasting protection, reducing later operation and maintenance costs. Carbon wire is naturally rust-free, resistant to acid and alkali, and resistant to salt spray erosion, allowing stable use in highly corrosive environments such as coastal bridges, sewage pools, and chemical plant buildings for 50 years. When paired with matching impregnating glue to form a sealed protective layer, there is no need for regular rust removal and anti-corrosion maintenance after completion, making it a cost-effective solution for long-term projects.
4. The construction has a high fault tolerance rate, allowing even novices to produce stable work. The fabric is flexible and bendable, allowing tight fitting at beam-column joints and arched surfaces, reducing the risk of hollowing and edge warping. Construction does not require large lifting equipment or hot cutting, resulting in low dust and noise pollution. A single person can complete the entire process, including base treatment, glue mixing, fabric application, and bubble removal.
5.Environmentally compliant, suitable for various public buildings. The product is formaldehyde-free, low VOC, and meets flame retardant standards, allowing for construction in densely populated areas such as residences, schools, hospitals, and shopping malls. The full set of qualification documents is complete, ensuring a high acceptance rate from supervision and housing construction departments.
Precisely adapts to engineering scenarios.
1. Industrial heavy-load engineering: workshop girders, heavy equipment bases, plant extension and renovation, seismic reinforcement of high-load floor slabs;
2. Municipal transportation infrastructure: reinforcement and improvement of bearing capacity for high-speed bridges, urban overpasses, tunnel box girders, and bridge piers;
3. Special corrosion engineering: repair of coastal docks, wastewater treatment tanks, chemical storage tanks, and underground utility tunnels;
4. Large-scale commercial renovation: underground parking garage, adding floors to shopping centers, and reinforcing load-bearing beams and columns of high-rise buildings.
