Isophthalic polyester resin is a thermosetting unsaturated polyester resin used as the matrix in many fiberglass reinforced plastic (FRP) systems. Compared with general-purpose orthophthalic polyester, it is often considered when the application places greater importance on moisture, chemical, or te..

Wastewater treatment facilities can expose materials to hydrogen sulfide, acidic conditions, chlorine-containing chemicals, moisture, and other aggressive media. The type and severity of exposure vary by process area, so material selection should be based on the conditions within each zone rather..

Mining and mineral processing environments can combine chemical exposure, abrasive solids, mechanical loading, and persistent moisture. These conditions can affect material selection for walkways, platforms, stair treads, and other access areas. FRP is used in some of these applications because its ..

When comparing FRP components, the manufacturing process matters because it influences how the reinforcement is arranged and how the finished part carries load. Pultrusion and molding are two widely used approaches for producing FRP components, but they create different product forms and reinforc..

Case at a glance: A roadway and adjacent public parking area were using a mix of steel and plastic marker posts. Some steel posts had been bent by vehicle contact, while some plastic posts had become faded and cracked after prolonged sun exposure. HotFRP supplied fiberglass marker posts for ..

Vinyl ester resin is a thermosetting matrix resin widely used in fiberglass reinforced plastic (FRP) composites, particularly where resistance to chemical exposure is an important design consideration. It is used in products such as FRP grating, cable trays, and structural profiles, with the appropr..

E-glass fiber is one of the most widely used reinforcement materials in fiber-reinforced plastic (FRP) composites. It is used in many FRP applications because it provides a practical balance of mechanical properties, availability, and cost. The way E-glass is arranged within the composite, however, ..

FRP grating load tables are configuration-specific engineering information, not universal capacity charts. A table is tied to a defined grating configuration and a stated basis for the reported load and deflection values. Reading it correctly means identifying the product configuration, support and..

Case at a glance: A mining operation replaced steel grating on elevated walkways and access platforms around processing equipment after years of moisture, chemical contact, and regular traffic had caused significant corrosion. HotFRP supplied heavy-duty molded FRP grating for the replacement..

Pulp and paper mills combine high humidity, process chemicals, washdown water, and continuous production. In areas such as bleach plants and chemical preparation zones, walkways, platforms, handrails, and cable-support systems may be exposed to oxidizing chemicals, acidic or alkaline process streams..

Case at a glance: A coastal bridge deck had experienced concrete deterioration associated with chloride exposure. The original steel reinforcement was corroding, contributing to cracking, spalling, and repeated patch repairs. For the deck replacement, HotFRP supplied glass fiber reinforced polymer..

Power generation facilities, substations, and other electrical infrastructure can expose structural and support components to moisture, chemical agents, salt-laden air, and nearby electrical equipment. These conditions influence the choice of materials for cable management, access systems, walkways,..

Food and beverage processing facilities place demanding requirements on floor and access materials. Production areas may be exposed to repeated washdowns, detergents, sanitizers, food residues, and varying temperatures. Walking surfaces also need to provide suitable traction while allowing the area ..

Case at a glance: In a chemical processing facility, an elevated access platform originally built with steel grating had developed corrosion at the edges and cut ends, increasing maintenance requirements. HotFRP supplied molded FRP grating as the replacement, based on the platform dimensions..

FRP products used outdoors are exposed to sunlight, moisture, and temperature changes over extended periods. Ultraviolet (UV) radiation is an important factor in the weathering of exposed polymer surfaces. Understanding how UV exposure affects FRP — and how formulation and surface protection influen..
