Fiberglass decking refers to a type of floor material commonly used in various settings including industrial, commercial, and residential areas. It is crafted from fiberglass-reinforced plastic (FRP), also known as glass-reinforced plastic (GRP), which combines glass fibers with polymer resin to create a robust, durable, and versatile material. Compared to traditional patio materials like wood or metal, fiberglass reinforced plastic can withstand heavy loads and adverse conditions.

How is Fiberglass Decking Manufactured?

Fiberglass decking is produced by integrating glass fiber reinforcement materials, such as glass and felt pads, with a thermosetting resin system. This combination is achieved through a process known as pultrusion, where the glass fiber and resin mixture is pulled through heated molds. The resulting panels can be connected using an innovative interlocking design to form a continuous solid surface that is easy to install and aesthetically pleasing.

What are the Different Types of Fiberglass Decking?

Fiberglass decking comes in several types, each designed to meet specific needs and applications. The differences between these types typically relate to the manufacturing process, intended use, and specific features they offer, such as durability, anti-slip properties, and load-bearing capacity.

  • Molded Grating Panels: These panels are created by combining coarse fiberglass yarn with a thermosetting resin system in a mold. They are highly durable and suitable for heavy-duty applications, typically used in industrial environments for walkways, platforms, and other areas requiring a sturdy anti-slip surface.
