High-Performance FRP & Fiberglass Gratings
Manufactured to withstand aggressive chemical exposures, saltwater corrosion, and high electrical voltage without compromising on load-bearing capacity.
Omkar Gratings manufactures and exports structural Fiber Reinforced Polymer (FRP/GRP) gratings engineered as an advanced substitute for conventional steel systems. Fabricated by combining continuous glass fiber roving with thermoset resin matrices, our molded and pultruded fiberglass gratings deliver unmatched chemical durability, non-conductivity, high strength-to-weight performance, and superior bi-directional load capabilities for mission-critical industrial flooring.
Superior Corrosion Resistance
Immune to acids, alkalis, solvents, and saltwater environments where carbon steel and galvanized gratings degrade rapidly.
Non-Conductive & Non-Sparking
Offers total dielectric safety for sub-stations and electrical rooms, while eliminating friction sparking in explosive oil & gas atmospheres.
Lightweight & Cost Effective
weighs roughly one-third of steel grating, reducing structural dead loads, freight costs, and the need for heavy lifting machinery during site installation.
High Impact & Fatigue Strength
Elastic memory enables repeated deflections under dynamic loads without permanent distortion or catastrophic deformation.
Fire Retardant Formulations
Compounded with fire-retardant additive packages meeting ASTM E-84 Class 1 flame spread rating with self-extinguishing characteristics.
Integrated Slip Resistance
Embedded silica grit or concave meniscus top surfaces deliver slip prevention under continuous grease, wet chemicals, or oil slick conditions.
Zero Maintenance Lifecycle
Molded-in resin pigments eliminate recurring maintenance, sandblasting, recoating, and hot-dip recoating cycles over decades of service.
Easy Fabrication on Site
Cut, notched, and adapted on location using standard circular saws fitted with diamond-grit abrasive blades without hot-work permit requirements.
Product Visual Gallery & Standard Formats
Strict quality-controlled molded meshes and pultruded structural bar profiles tested to global plant criteria.
Cross-Industry Operating Environments
