Product information
Pultruded GRP gratings consist of pultruded bearing bars and crossbars. Glass content is approximately 68%. Pultruded gratings provide higher stiffness than moulded GRP gratings, enabling longer spans or a reduced construction height depending on the application.

Construction and materials
The special arrangement and bonding of bearing bars and crossbars ensure long-term stability. Bearing bars are manufactured according to EN 13706 with longitudinal glass-fibre rovings, cross-reinforcing glass-fibre mats and a surface veil.

Sections and surface options
Pultruded gratings are available with I‑bar or T‑bar cross sections. Multiple surface finishes are offered; anti-slip properties and classification should be chosen according to the operational environment and safety requirements.

Accessories / Fixings
