Product Overview

BUILT FOR
EXTREME
CONDITIONS

Our Corrugated Spiral Pipe is precision-engineered for environments that demand more. The corrugated profile dramatically increases radial stiffness and resistance to external pressure — delivering structural integrity that smooth-wall duct simply cannot match.

Fabricated from premium galvanized steel with 90 GSM zinc coating, every section is manufactured to exact tolerances. Whether you're running exposed ductwork in a warehouse, an underground ventilation run, or a high-pressure exhaust system, this duct performs without compromise.

Core Features

ENGINEERED
EXCELLENCE

Every detail is intentional — from the corrugation pitch that adds stiffness, to the locked spiral seam that eliminates air loss and keeps your system running at peak efficiency.

🔩
High-Strength Construction

The corrugated profile enhances radial stiffness and load-bearing capacity — up to 20% stronger than equivalent smooth-wall pipe of the same gauge, with no added weight.

🛡️
Corrosion-Resistant Steel

Premium galvanized steel with 90 GSM zinc coating provides exceptional resistance to rust, moisture, and harsh environmental conditions for decades of service life.

💨
Superior Airflow

Optimized internal geometry delivers consistent, efficient airflow with reduced friction loss — keeping pressure drop minimal across the entire run for maximum system efficiency.

Fast Installation

Lightweight yet rigid sections with precise end tolerances connect quickly and securely, reducing labor time and total installation cost on every project.

📐
Custom Sizes Available

Available in 4" to 22" diameters in 5 ft and 10 ft standard lengths. Non-standard dimensions and configurations manufactured to your exact project specifications.

🌡️
Negative Pressure Ready

The corrugated structure provides exceptional collapse resistance under negative pressure — making it the definitive choice for exhaust, dust extraction, and vacuum systems.

Key Advantages
🏗️

20% Stronger Than Smooth Pipe

Corrugated spiral pipe outperforms longitudinal and smooth-wall alternatives in rigidity and load resistance at the same gauge.

🔒

Tight Seam — Zero Air Loss

Precision-locked spiral seams prevent air escape, improving system efficiency and cutting energy costs over the installation's lifetime.

🏭

Industrial-Grade Materials

20, 22, 24, and 26 gauge options with 90-grade steel and 90 GSM zinc coating. Built to outlast any competitor on the market.

APPLICATIONS
Use Cases

WHERE IT PERFORMS

01
🏢
Commercial HVAC

Ideal for large-scale heating, ventilation, and air conditioning in office buildings, schools, hospitals, and retail spaces.

02
🌫️
Dust & Fume Extraction

The corrugated structure handles high-velocity dust-laden air and negative pressure without collapse or deformation.

03
🏗️
Industrial Ventilation

Factories, plants, and warehouses requiring robust exhaust ducting that holds up to demanding conditions day after day.

04
🌱
Underground Ductwork

Enhanced rigidity makes corrugated spiral duct suitable for buried runs where smooth-wall duct risks deformation over time.

05
⚗️
Pharma & Clean Rooms

Precise airflow control and airtight seams for controlled environments requiring ultra-consistent performance standards.

06
🔥
High-Pressure Systems

Withstands positive and negative pressure extremes — the definitive choice for spray booths, welding booths, and blower stacks.
