Product catalog summary
Introduction to Pultrusion
"Pultrusion" is a continuous molding process where fiberglass materials are pulled through a resin bath and a heated die to form a hardened composite in a specific shape.

Pultruded Gratings Overview
Eurograte® pultruded gratings are high-strength fiberglass bars designed to replace metal gratings in corrosive environments. They offer benefits such as corrosion resistance, lightweight, and ease of handling.

Key Features
  • Corrosion Resistance: Made with isophthalic and vinyl ester resin systems for chemical resistance.
  • Mechanical Resistance: High fiberglass content provides strength and stiffness.
  • Lightweight: Less than half the weight of steel gratings.
  • Fire Retardancy: Meets ASTM E84 and ASTM D635 standards.
  • Maintenance Free: No need for scraping or painting.
  • UV Protection: Includes UV inhibitors for resistance.
  • Safety: Slip-resistant surface and non-conductive properties.

Applications
Suitable for industries such as automotive, chemical, marine, oil & gas, and water treatment.

Resin Selection
  • Isophthalic Resin: For moderate corrosive environments, standard color yellow.
  • Vinyl Ester Resin: For highly corrosive environments, standard color grey.

Load Tables and Specifications
Detailed load-deflection tables are provided for different grating thicknesses (25.4 mm, 38.1 mm, 50.8 mm) and span codes, indicating typical values for uniformly distributed and concentrated line loads.

Grating Selection Guide
Comparison between molded and pultruded gratings in terms of mechanical resistance, chemical resistance, impact resistance, and other features.

Accessories and Other Products
Includes structural shapes, ladders, guardrails, and molded gratings.

Pultruded Gratings-2

What is Pultrusion “Pultrusion” is a continuous molding process in which fiberglass longitudinal roving, multidirectional mat and a synthetic surfacing veil are passed through a thermosetting resin bath. The wetted fiberglass reinforcements are then “pulled” through a heated steel die where the composite hardens in the desired geometric shape.

Corrosion resistance Manufactured with premium isophthalic and vinyl ester resin systems with a synthetic surfacing veil, Eurograte® pultruded gratings offer superb chemical resistance. Mechanical resistance The high percentage of fiberglass in the load bearing bars provides high strength to weight ratio and extremely high unidirectional stiffness. Lightweight With less than one-half the weight of comparable steel gratings they are easy to handle without heavy equipment and weight savings can be realized. Fire retardancy Eurograte® pultruded gratings are designed with fire retardant resin systems...

SELECTION & DESCRIPTION CODE OPEN SPACE WEIGHT KG/M2 Eurograte® pultruded gratings are available in two standard panel dimensions: 914x6096mm and 1220x6096mm. Other dimensions available on demand. RESIN SELECTION Eurograte® pultruded gratings are manufactured using two resin formulations that are suitable for most of the industrial applications. Both resin systems provide superior corrosion resistance compared to metal gratings. Isophthalic resin system This resin formulation provides a flame spread rating of less than 25 according to ASTM E84 norm. Gratings in this resin formulation are designed...

The load values could have a variation of +/- 10%. Loads In case of pedestrian loads we suggest selecting a grating with deflection limited to the lesser of 10mm or span divided by 125. For a stiffer feeling, limit deflection to span divided by 200.
