Product Introduction

1.30×40×6mm Fiberglass I-Beam Introduction

30×40×6mm Fiberglass I-Beam is a high-strength pultruded fiberglass structural beam engineered for medium-duty load-bearing and spanning applications. As a superior corrosion-proof, lightweight alternative to traditional steel I-beams, our 30×40×6mm Fiberglass I-Beam delivers outstanding rigidity, structural stability and long-term durability. It is the ideal choice for industrial flooring supports, platform framing, roof systems and corrosive environment structural projects worldwide.

2.Key Advantages of Our 30×40×6mm Fiberglass I-Beam

  • High Load-Bearing & Structural Rigidity: The standard 30×40×6mm I-shaped cross-section provides excellent bending resistance and overall stability, perfectly suited for medium-span load-bearing structures.
  • Outstanding Corrosion & Chemical Resistance: Fully resistant to acids, alkalis, saltwater, humidity and UV radiation; no rust, no rot, and requires no painting or anti-corrosion maintenance over its service life.
  • Non-Conductive & Flame Retardant: Inherent electrical insulation property with optional fire-retardant grades, safe for use in power plants, electrical substations and flammable industrial zones.
  • Lightweight & Cost-Effective: Significantly lighter than steel I-beams, reducing transportation, handling and foundation load; easy to cut, drill and install on-site.
  • Long Service Life & Low Maintenance: Weather-resistant and fatigue-proof design offers a lifespan of over 20 years, greatly lowering later maintenance and replacement costs.

3.Wide Range of Industrial Applications

Our 30×40×6mm Fiberglass I-Beam is widely used in various industrial and construction fields:
  • Industrial Platforms: Factory walkway supports, working platform beams, and mezzanine floor framing.
  • Roof & Wall Structures: Workshop roof beams, greenhouse main frames, and industrial building load-bearing members.
  • Marine & Coastal Areas: Seaside facility beams, dock structural supports, and salt-fog resistant spanning components.
  • Chemical & Wastewater Plants: Corrosive workshop structural beams, sewage tank support frames, and anti-corrosion overhead structures.
  • Municipal & Public Facilities: Landscape bridge beams, safety structure supports, and outdoor anti-rust engineering profiles.
