Fiberglass Grating is ideal when you require a product that is highly resistant to corrosive environments
Fiberglass Grating is ideal when you require a product that is highly resistant to corrosive environments, fire retardant, non-conductive, light weight, low maintenance or architecturally attractive.

The two primary manufacturing processes used to produce Marco FRP Grating products are Pultrusion and Open Molding. Both processes produce high quality, uniform construction.

Open Molded Grating

  • Isophthalic- Your choice against acids and other chemicals commonly found in most industrial and chemical processing applications. Flame spread rating is Class I, 25 or less when tested in accordance with ASTM E84. Isophthalic Base
  • Vinyl Ester- The strongest resin system available to protect against caustics and acids found in the toughest environments. Flame spread rating is Class I, 25 or less when tested in accordance with ASTM E84. Vinyl Ester Base
  • Food Grade-A resin designed for USDA food processing applications. Flame spread rating is ClassII, 75 or less when tested in accordance with ASTM E84. Isophthalic Base
  • Extra Fire Retardant- Used when the lowest flame spread rating is required. Flame spread rating is Class I, 10 or less when tested in accordance with ASTM E84. Isophthalic Base

    Pultruded Grating

  • Isophthalic- Good corrosion resistance in moderately corrosive industrial areas. Flame spread rating is Class I, 25 or less when tested in accordance with ASTM E84. Isophthalic Base
  • Vinyl Ester- Highly resistant to both acidic and alkaline environments. Flame spread rating is Class I, 25 or less when tested in accordance with ASTM E84. Vinyl Ester Base
  • Food Grade-USDA approved resin for food processing applications
  • Phenolic- Good corrosion resistance and excellent fire and smoke resistant. ASTM E84 Class I, flame spread rating of 15 or less and smoke developed of 50 or less.
