Yingnai FRP Channel is a pultruded open structural profile for equipment frames, platform beams, ladder rails, supports and corrosion-resistant construction. Continuous fiberglass reinforcement provides strength and dimensional stability while reducing weight compared with metallic sections. Channel depth, flange width, thickness, resin formulation, length and connection details can be customized for different load and environmental conditions.
| Item | Typical Technical Specification |
