Product Overview
The pultruded GRP I-profile 300x150x15 (also referenced as I300x150x15) combines good structural strength with a lightweight design, weighing 15.70 kg/m – approximately 80% lighter than an equivalent steel I-beam by weight. This composite profile is suitable for challenging environments where corrosion or conductivity limits traditional materials. For related products, see our pultruded profiles, FRP rebar, pultrusion machines, and pultrusion dies. Other beam depths are listed on our H beam and I beam page.

Key Benefits
- Corrosion Resistant: Withstands acids, alkalis, salts, and other aggressive chemicals
- Lightweight: Lower weight than steel can reduce transportation and installation effort
- Easy Processing: Can be cut, drilled, and assembled using standard tools
- Non-Conductive: Provides electrical insulation and reduces sparking hazards
- Thermal Performance: Maintains structural integrity in temperatures from -40°C to +80°C
- Cost-Effective: Can lower lifetime costs through reduced maintenance and longer service life in corrosive environments
Performance Data
The I300x150x15 profile has been tested to withstand distributed loads of up to 2,500 kg over a 3-meter span with deflection less than L/250. This makes it suitable for structural applications where both strength and weight are important.
Common Applications
- Chemical processing facilities
- Wastewater treatment plants
- Offshore platforms and marine structures
- Food processing environments
- Infrastructure in mining operations
- Agricultural buildings exposed to corrosive conditions

Frequently Asked Questions
Q: How do I connect these I-profiles to other structural elements?
A: Our profiles can be joined using mechanical fasteners (bolts, rivets), adhesive bonding, or a combination of both methods. For optimal structural integrity, we recommend our specially formulated structural adhesives along with stainless steel bolts.
Q: What is the expected lifespan of these profiles?
A: In typical industrial environments, GRP profiles can provide a long service life with minimal maintenance requirements. Actual service life depends on load, environment, and resin system.
Q: Can these profiles be used in fire-sensitive applications?
A: Yes, we offer fire-retardant formulations that meet Class 1 fire rating standards. These should be specified at the time of ordering.
Q: How do installation costs compare to traditional materials?
A: Due to their lightweight nature, installation typically requires less labor and can reduce or eliminate the need for heavy lifting equipment, resulting in potential cost savings.
Q: Are these profiles environmentally friendly?
A: Their long service life, minimal maintenance requirements, and eventual recyclability make them an environmentally responsible choice compared with alternatives requiring frequent replacement or treatment.
Q: What engineering support do you provide?
A: Our technical team offers support including load calculations, installation guidance, and custom design solutions for your specific application requirements.
