Fiberglass: Safe, Cost‑Effective, Code‑Compliant Structural Solution

When choosing a cost‑effective material for industrial construction, fiberglass stands out. Compared with steel or aluminum, molded fiberglass is lighter, corrosion‑resistant, and offers comparable strength—all at a fraction of the cost.

Why Fiberglass Wins in the Workplace

Like steel and aluminum, fiber‑reinforced plastic (FRP) comes in grades tailored to specific environments. Regardless of the grade, FRP consistently delivers:

• Easy Fabrication & Installation – FRP can be molded on site with simple carpentry tools and blades. Its low weight eliminates the need for welding, heavy lifting, or special equipment.
• Durable Gel Coat – A hard gel coat finishes the surface in a range of colors and hardness levels, adding corrosion resistance, traction, and protection for industry‑specific needs.
• Cost Efficiency – While stainless steel or aluminum may appear cheaper initially, installation, maintenance, and repair costs make fiberglass the most economical choice over its lifecycle.
• Exceptional Stiffness – FRP can be up to three times as rigid as wood and resists deformation under maximum loads, outperforming steel and aluminum in impact scenarios.
• Resistant to Corrosion, Rot & Termites – Fiberglass tolerates water, chemicals, salt spray, and insect attack without rusting or rotting, eliminating the need for galvanizing or painting.
• High Flexural Strength – FRP’s strength‑to‑weight ratio exceeds that of aluminum and steel, providing superior performance under bending forces.
• Lightweight – Fiberglass weighs one‑quarter of steel and two‑thirds of aluminum, simplifying transport, handling, and reducing labor costs.
• Integrated Color – Pigments are mixed into the resin, giving a uniform color that does not fade—paint is only required for continuous sun exposure.
• Thermal Insulation – With minimal thermal conductivity, fiberglass stays cool in hot environments, unlike metal, which can conduct heat dangerously.
• Non‑Conductive – FRP does not carry electricity, eliminating grounding requirements and making it safe for high‑voltage applications.
• Signal Integrity – Fiberglass does not interfere with radio or electrical signals, ensuring reliable operation in sensitive settings.

These attributes make FRP the superior choice for structures where cost, safety, and durability matter.

Compliance Made Simple

Building codes demand that structures meet fire, stability, ADA, and other safety standards for their entire service life. Fiberglass adapts easily to these requirements at a lower cost than traditional metals.

Fire‑Safe Construction

DEFI’s Phenolic FRP grating delivers the highest fire protection for safety and durability. Its non‑combustible resin keeps the structure intact under prolonged fire exposure, meeting and exceeding L2 performance metrics for evacuation zones such as fire exits and lifeboat launch platforms.

Key Advantages of Phenolic Fiberglass

• Very low smoke index
• Low toxic fume emissions
• Heat resistance up to 300 °F
• Superior corrosion resistance
• Minimal maintenance

ADA‑Compliant Solutions

DEFI’s ADA‑compliant fiberglass grating combines durability with precise mesh geometry that supports high pedestrian traffic, including those with mobility aids. Its fine mesh is comfortable for barefoot use, making it ideal for water parks and public pools.
