Fiberglass Ducting System - Busubait Fiberglass Company

High-quality Fiberglass Ducts by Busubait FRP Manufacturers

Busubait Fiberglass Company designs and manufactures FRP (Fiberglass Reinforced Plastic) ducting systems used to move air, fumes, and gases safely in industrial environments. Our ducts are known for their corrosion resistance, lightweight structure, and long service life — making them ideal for areas where metal ducts cannot perform well.

These ducts are made using high-quality fiberglass and resins that resist chemicals, moisture, and heat. Each system is custom-built to fit your project needs and to ensure smooth airflow, safety, and reliability in demanding conditions.

Key Features of FRP Ductings

Corrosion Resistant

FRP ducts resist acids, alkalis, moisture, and chemical fumes. They do not rust or corrode even in harsh environments.

Lightweight and Strong

The ducts are strong yet lightweight, which makes them easy to install, transport, and maintain.

Smooth Airflow

A seamless inner surface ensures minimal friction loss and keeps air moving efficiently through the system.

UV and Fire Resistant

Optional UV and fire-retardant coatings protect the ducts from outdoor weather and meet safety standards for industrial use.

Temperature Resistant

FRP ducts remain stable and strong across a wide temperature range — suitable for both hot and cold air systems.

Custom Engineering

Tailored solutions for specific project requirements with custom shapes, sizes, and material specifications.

Types of FRP Ducting

Circular FRP Ducts

Used for large airflow volumes and high-pressure systems.

Standard sizes range from 100 mm to 3000 mm and beyond
Ideal for industrial ventilation and exhaust systems
Optimal for high-velocity applications

Rectangular FRP Ducts

Designed for limited space areas where round ducts cannot fit.

Made with strong reinforcement to prevent bending or vibration
Used in air handling units, HVAC, and exhaust headers
Space-efficient design for tight installations

Dual-Laminate FRP Ducts

Combine a thermoplastic liner (PP, PVC, CPVC, or PVDF) inside a fiberglass shell.

Provide extra protection for highly corrosive chemical fumes
Commonly used in chemical and fertilizer plants
Enhanced chemical resistance with structural strength

Custom FRP Ducts and Fittings

Available in any shape or size including elbows, tees, reducers, and transitions.

Custom-built to suit site layouts and installation requirements
Engineered for specific airflow and pressure conditions
Compatible with existing ductwork systems

Applications

Materials and Manufacturing

High-Quality Resins

Ducts are made using polyester, vinyl ester, or epoxy resins based on chemical and temperature needs.

Fiberglass Reinforcement

Layers of woven fiberglass add strength while keeping weight low for easy installation.

Dual-Laminate Option

Thermoplastic liners (PP, PVC, PVDF) are added for maximum corrosion protection.

Manufacturing Methods

Circular ducts are made using filament winding, while rectangular ducts are hand-laminated for precision.

Protective Finish

The outer surface is coated with UV- and weather-resistant topcoat for longer life.

Quality Control

Every duct is inspected for wall thickness, finish, and structural strength before delivery.

Advantages of FRP and PP FRP Ducts

Excellent Corrosion Resistance:
Our FRP and PP FRP ducts are highly resistant to corrosion, eliminating the need for additional anti-corrosion treatments. This resistance ensures that the ducts maintain their structural integrity and performance over time, even in harsh chemical environments. Unlike metal ducts, they do not produce secondary pollution, making them ideal for applications involving water and other sensitive media.
Lightweight and High Strength:
Our FRP ducts weight significantly lesser than traditional ducts. This lightweight nature not only simplifies transportation and installation but also reduces overall handling costs. Despite their light weight, FRP ducts offer high strength and durability, making them a robust choice for various applications.
Long Length of Single Pipe:
Our FRP ducts are available in extended lengths, minimizing the need for joints and accelerating installation processes. This feature enhances the overall quality and reliability of the pipeline, reducing potential leak points and installation time.
Smooth Inner Wall:
The internal surface of our FRP ducts is smooth, which reduces flow resistance and enhances flow rates. This design improvement allows for smaller diameter pipes to transport the same volume of fluid compared to metal pipes, resulting in improved energy efficiency and reduced operational costs.
Versatile Applications:
FRP ducts are versatile and suitable for use in various industries, including petroleum, chemical, and drainage sectors. Our PP FRP ducts offer additional benefits such as excellent thermal insulation, low-temperature resistance, and resistance to UV rays, making them ideal for both indoor and outdoor installations.
