Product USP’s

Precision-Built Air Ducts for Performance, Efficiency, and Flexibility

Multiple Shapes & Material Options

Choose from rectangular, round, or oval ducts made with galvanized steel, stainless steel, or aluminum - customized to meet architectural and operational requirements.

Superior Leak Resistance

Sealed joints, reinforced corners, and gasketed flanges reduce air leakage and improve energy efficiency, ensuring optimal system performance.

Insulated for Energy Efficiency

Internal or external insulation using nitrile rubber helps minimize thermal loss and condensation—boosting HVAC efficiency and reducing energy bills.

SMACNA-Compliant Fabrication

Built with precision according to SMACNA standards, our ducts maintain high pressure class ratings and sealing classes (A, B, C) up to 2000 Pa.

Quick & Easy Installation

Modular, prefabricated duct sections with TDF/TDC or angle flanges simplify on-site assembly, saving time and labor costs.

Custom-Fit to Project Needs

CNC-fabricated ducts tailored to project blueprints eliminate on-site modifications, delivering precision fit and fast commissioning.

Engineered for Every Space:

At ZECO, we understand that every project has its own space constraints and performance requirements. That’s why we offer three precision-crafted types of air distribution ducts: Rectangular, Oval, and Round –each designed to optimize airflow, maximize efficiency, and adapt to unique architectural and operational demands. Whether you’re working with tight ceiling spaces, exposed duct layouts, or high-performance systems, ZECO has the perfect ducting solution tailored for you.

Choose the Right Duct for Your HVAC Needs

Rectangular Duct

ZECO rectangular ducts are ideal for installations with limited vertical space. Their flat design allows for easy integration into ceiling voids and tight spaces, making them perfect for commercial and industrial buildings where space efficiency is critical.

Round Duct

ZECO round ducts ensure superior airflow and reduced air resistance, making them highly efficient for ventilation systems. Easy to install and cost-effective, they are a preferred choice for many HVAC applications.

Oval Duct

Combining the low-profile advantage of rectangular ducts with the airflow efficiency of round ducts, ZECO oval ducts offer both aesthetics and performance. They are perfect for exposed installations and environments that require both form and function.

Key Highlights

Precision in Every Material

At ZECO, we understand that material selection plays a critical role in the performance, durability, and efficiency of air distribution systems. That’s why we offer ducts fabricated from the highest quality materials – Galvanized Iron (GI), Stainless Steel (SS), and Aluminum – each suited to different environments and project specifications. Explore the strength and suitability of each duct type below:

GI Ducts
(Galvanized Iron)


ZECO’s GI ducts are fabricated from premium galvanized steel, making them the most widely used option in commercial and industrial HVAC systems. These ducts offer excellent resistance to corrosion, ease of fabrication, and an ideal balance between performance and cost. Ideal for indoor installations in offices, malls, hotels, and institutions.
  • Standard HVAC installations
  • Commercial spaces
  • Medium humidity environments

SS Ducts (Stainless Steel)


Built from SS 304 or SS 316 grades, ZECO’s Stainless Steel ducts are designed for harsh environments where corrosion resistance and hygiene are non-negotiable. Perfect for hospitals, cleanrooms, pharmaceuticals, food processing plants, and coastal or chemical-exposed areas.
  • High-humidity or chemical environments
  • Healthcare & pharma industries
  • Food-grade air distribution

Aluminium Ducts


Aluminium ducts are lightweight, corrosion-resistant air distribution systems ideal for HVAC applications. Known for their durability and ease of installation, they offer excellent thermal performance and are suitable for cleanroom, commercial, and industrial environments where hygiene and efficiency are critical.
  • Lightweight installations
  • Coastal & marine zones
  • Specialized industrial needs

Applications

FAQ's

ZECO manufactures three main types of ducts—Rectangular, Oval, and Round—to suit various space layouts, airflow requirements, and aesthetic preferences in HVAC systems.

Our ducts are made from high-quality Galvanized Iron (G.I.), Stainless Steel (SS 304/316), or Aluminum, depending on application needs and environmental conditions.

Yes, we offer both internally and externally insulated ducts using materials like Glass Wool, Rock Wool, or Nitrile Rubber for thermal and acoustic performance.

Absolutely! We manufacture ducts as per your project drawings and specifications, ensuring custom sizes, fittings, and configurations for seamless integration.

Yes. Our ducts are manufactured following SMACNA, ASHRAE, and other international standards to ensure top-tier performance, safety, and efficiency.

We use leak-proof sealing techniques, including Pittsburgh or Snap Lock seams and high-quality gaskets or sealants, to minimize air leakage and improve system efficiency.

ZECO ducts are ideal for commercial buildings, industrial plants, hospitals, data centers, malls, airports, and residential projects requiring centralized HVAC systems.

Each duct undergoes phase-wise quality inspections, precision fabrication, and pressure testing to ensure performance, durability, and compliance.

We use advanced seam technologies, gaskets, sealants, and flanged joints that comply with SMACNA sealing class A, B, or C for maximum leak prevention.

We provide both internal and external insulation using closed or open-cell nitrile rubber, depending on acoustic and thermal needs.

Thanks to prefabricated modular design and precision fitment, installation is quicker and smoother, reducing overall project timelines.
