At Hengshui Ruibin New Materials LLC, we specialize in the design and manufacture of high-performance FRP pultruded profiles for industrial sectors. Our Non-Corrosive FRP Pultruded I-Beam, sized at 100x50mm, is specifically developed for paper mill plants that operate in humid, chemical-laden, and UV-exposed conditions. This structural component provides a balanced combination of load-bearing capacity and long-term durability, representing a smart upgrade from conventional metallic beams. By integrating advanced composite technology, we deliver products that significantly reduce downtime and maintenance expenses for our customers.
Product OverviewThis I-beam is manufactured through the continuous pultrusion process, ensuring high fiber alignment and uniform cross-section. The nominal dimensions are 100mm in height and 50mm in flange width, yielding an efficient section modulus for supporting racking, platforms, and equipment stands. The product is supplied with a smooth surface finish and is available in custom lengths to match your exact installation requirements. Its non-corrosive nature makes it a reliable choice for environments where steel would rapidly degrade.
Key Features and Benefits- Chemical Resistance: The polyester or vinyl ester resin matrix resists attack from sulfuric acid, sodium hydroxide, chlorine solutions, and other aggressive chemicals commonly present in paper production.
- UV Stabilization: A UV-inhibited formulation protects the polymer from sunlight-induced degradation, ensuring stable mechanical properties over many years of outdoor exposure.
- Lightweight: At roughly one-quarter the weight of steel, the profile is easier to transport, handle, and install, resulting in significant savings on rigging and labor costs.
- High Strength: The pultruded longitudinal fibers provide high tensile and flexural strength, allowing the beam to carry heavy loads without permanent deformation.
- Electrical Insulation: FRP is non-conductive, making these I-beams suitable for electrical substations, cable trays, and other zones where accidental contact with live circuits must be avoided.
- Low Thermal Conductivity: Unlike metal beams, this product does not transmit heat rapidly, helping to reduce condensation and maintaining a more stable temperature in sensitive operations.
- Cut-to-Length Service: We can cut every beam to the precise dimensions you need, from short lintels to long-span supports, eliminating scrap and reducing fabrication time.
- Minimal Maintenance: No painting, galvanizing, or cathodic protection is required. A simple wash is enough to keep the profile clean and functional.

Paper mills are notoriously challenging for conventional materials because of the combination of moisture, chemical vapors, mechanical wear, and ultraviolet exposure. Our FRP I-beams are widely used for:
- Supporting platforms, gratings, and walkways in pulp preparation areas.
- Framework for chemical storage tanks and dosing stations.
- Cable trays and ladder racks in electrical rooms and cable tunnels.
- Pipe supports and pipe racks that carry corrosive slurries and liquids.
- Structural members for ventilation ducts and fume extraction systems.
- Gantry and lifting frames in wet processing lines.
Advanced pultrusion technology provides consistent fiber-to-resin distribution, repeatable cross-sectional density, and predictable mechanical properties. This results in stable behavior under both static and dynamic loads. Furthermore, the composite design is inherently resistant to galvanic corrosion and does not suffer from metal fatigue in the same manner as steel. Because we are a hands-on manufacturer, we can tailor resin formulations, glass content, surface finishes, and dimensional tolerances to suit a particular paper mill application. Optional flame-retardant and low-smoke resin systems are available for areas with strict fire-safety requirements, and a range of color options can be supplied for safety identification.
Quality Assurance and Packaging
At our factory, each profile is inspected for surface imperfections, dimensional accuracy, and mechanical integrity before dispatch. The I-beams are packed in bundles with protective padding, separating layers to prevent abrasion during transport. We provide standard export packaging as well as custom packing solutions for fragile coatings or special sizes. Because the beams are non-corrosive and UV-stable, they do not require special climate-controlled storage when the packaging is intact.

Frequently Asked Questions-
Q1: What is the minimum order quantity for this FRP I-beam?
We are flexible on order size. The MOQ can be adjusted based on the project’s required length and quantity. For specific product configurations, please contact our sales team to confirm the current minimum requirement. -
Q2: Can you supply the beams cut to my exact length?
Yes, cut-to-length is a standard service. We can cut every I-beam to the exact dimensions you specify, typically up to 12 meters, with clean edges and minimal fiber damage. -
Q3: How does the weight of an FRP beam compare with a steel beam of similar size?
FRP pultruded profiles generally weigh about one-quarter to one-fifth as much as equivalent steel shapes. This reduces support structure deadload and makes handling and installation easier and safer. -
Q4: Is this product resistant to the chemicals used in paper mills?
Yes. The resin matrix can be selected from a range of systems that provide strong resistance to sulfuric acid, caustic soda, chlorine, and other aggressive chemicals. For specific chemical exposure lists, we can recommend a suitable resin. -
Q5: Do you provide different resin options for increased flame retardance?
Flame-retardant and low-smoke resin systems are available as an option. Please specify your fire-safety standard or performance requirement, and we will recommend a formulation that meets your needs. -
Q6: Can I get product samples for laboratory testing before placing a bulk order?
Sample pieces are available upon request. We recommend evaluating the mechanical characteristics and chemical compatibility in your own environment before proceeding with large-scale procurement. -
Q7: What is the typical lead time for cut-to-length production?
Lead time depends on quantity, resin choice, and production scheduling. Once we receive your specifications, we can provide an accurate lead time with your formal inquiry. -
Q8: How do you package the profiles for export to avoid damage?
Each bundle is secured with protective spacers and wrapped to prevent surface scratches and bending. For long-distance shipment, we use reinforced wooden pallets or steel frames, as needed.
