Product Introduction<\/h2>\n

1.30\u00d740\u00d76mm Fiberglass I-Beam Introduction<\/h3>\n

30\u00d740\u00d76mm Fiberglass I-Beam<\/strong><\/a> 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\u00d740\u00d76mm 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.<\/p>\n

Feature<\/td>\nDescription<\/td>\n<\/tr>\n
High Load-Bearing & Structural Rigidity<\/td>\nThe standard 30\u00d740\u00d76mm I-shaped cross-section provides excellent bending resistance and overall stability, perfectly suited for medium-span load-bearing structures.<\/td>\n<\/tr>\n
Outstanding Corrosion & Chemical Resistance<\/td>\nFully 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.<\/td>\n<\/tr>\n
Non-Conductive & Flame Retardant<\/td>\nInherent electrical insulation property with optional fire-retardant grades, safe for use in power plants, electrical substations and flammable industrial zones.<\/td>\n<\/tr>\n
Lightweight & Cost-Effective<\/td>\nSignificantly lighter than steel I-beams, reducing transportation, handling and foundation load; easy to cut, drill and install on-site.<\/td>\n<\/tr>\n
Long Service Life & Low Maintenance<\/td>\nWeather-resistant and fatigue-proof design offers a lifespan of over 20 years, greatly lowering later maintenance and replacement costs.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
