About this product

Product information from the supplier.

Jrain's molded fiberglass gratings and covers provide a high-performance, corrosion-resistant alternative to traditional metallic flooring. Engineered for extreme durability, these panels feature a concave non-slip walking surface and are molded in one piece to ensure structural integrity. By integrating high glass content at the bottom of each grating, we achieve a superior safety factor and exceptional tensile strength, making them ideal for heavy-duty industrial environments.

Designed for maximum efficiency and versatility, our FRP gratings are lightweight yet robust, allowing for easy on-site cutting to minimize material waste. With bidirectional load-bearing capabilities, these systems can be installed without the need for continuous side support. Whether used in chemical plants or sewage treatment facilities, Jrain gratings offer a low-maintenance, cost-effective solution that withstands the harshest corrosive atmospheres.

Frequently Asked Questions

Q: What makes fiberglass gratings better than steel in chemical plants?

Fiberglass (FRP) is inherently corrosion-resistant. Unlike steel, it does not rust or degrade when exposed to acids and alkalis, eliminating the need for expensive coatings and frequent replacements.

Q: Can FRP gratings be cut to size on-site?

Yes, Jrain's molded panels are designed for easy fabrication. They can be efficiently cut on-site to fit specific dimensions, which helps minimize waste and reduces installation time.

Q: Is the walking surface slip-resistant?

Our standard gratings feature a concave profile for excellent skid resistance. For environments requiring maximum traction, we also offer optional grit-top surfaces.

Q: What is meant by "Bidirectional Load Bearing"?

This means the grating has load-bearing bars running in both directions, allowing the panels to be installed without needing continuous side supports in one specific direction.

Q: How does UV inhibition work in Jrain gratings?

All our thermosetting resin systems contain integrated UV inhibitors that prevent the fiberglass from yellowing or becoming brittle when exposed to direct sunlight.

Q: Which resin systems are available for customized needs?

We offer five different thermosetting resin systems tailored to specific industrial needs, ranging from general purpose to high-chemical resistance and fire retardant options.
