We work with a wide range of materials including galvanized iron (GI), stainless steel (SS), aluminium, and mild steel (MS) to suit different environmental conditions and applications. The fabrication process includes careful cutting, folding, welding, and assembling of sheet metals into ductwork systems of various shapes like rectangular, circular, and spiral. Our in-house setup is equipped with advanced CNC machines and hydraulic presses to maintain consistent precision across all units.

Types of Ducting Fabricated

Depending on the project’s technical requirements, we provide supply and installation of:

• GI Ducts for general HVAC applications

• SS Ducts for hygienic environments like hospitals and laboratories

• Aluminium Ducts for lightweight applications

• Spiral Ducts for aesthetic and space-saving designs

• Acoustic Ducts for noise reduction

Fabrication Process

Our process begins with a complete design review, followed by drafting and dimension approval from the client. Next, raw sheets are cut to exact measurements and folded using press brakes. Edges are joined using spot welding or riveting based on the requirement. Finally, every duct is inspected for shape accuracy and leakage. If required, internal linings such as insulation or acoustic material are also added before dispatch.

Quality and Standards

We strictly follow international fabrication standards such as SMACNA (Sheet Metal and Air Conditioning Contractors’ National Association) to ensure product reliability. Our QA/QC team performs regular checks on weld joints, thickness, alignment, and airflow capacity. The ducts are corrosion-resistant and structurally strong, capable of withstanding environmental wear and tear over the years.

Applications

Our fabricated ducting systems are installed in:

• Commercial office buildings

• Industrial production units

• Shopping malls and multiplexes

• Pharmaceutical units

• Educational institutes

• Hotels and restaurants

Skilled Workforce and Timely Delivery

Our workforce includes highly trained ducting technicians, welders, and sheet metal engineers who ensure zero tolerance for design errors. Every project, whether small or large scale, is executed with a timeline-focused approach. We believe in providing not just a product, but a complete ducting solution with fast turnaround and professional support.

The fabrication of ducting is a vital component in the heating, ventilation, and air conditioning (HVAC) systems used in residential, commercial, and industrial buildings. KNY Company proudly offers a robust and customized ducting fabrication service that meets all technical standards, industry specifications, and client requirements. We understand that ducting is not just about airflow—it is about temperature control, energy efficiency, noise reduction, and safe ventilation. That’s why our ductwork fabrication process is engineered to be precise, durable, and adaptable to every type of infrastructure.

Our approach begins with comprehensive planning and duct layout designing. This stage involves detailed measurements, airflow calculation, load assessments, and architectural alignment. Every project is evaluated by our in-house team of mechanical engineers and HVAC specialists who ensure optimal sizing and route planning. The goal is to reduce resistance in the duct path while maximizing energy savings and distribution efficiency.

Once the layout is finalized, material selection plays a crucial role in duct fabrication. KNY Company uses only high-quality galvanized iron (GI), stainless steel (SS), and aluminum sheets, depending on the application and environment. For corrosive or moist environments, stainless steel or pre-insulated aluminum ducts are chosen to increase durability. Our materials comply with IS and ASTM standards, ensuring top-tier strength, longevity, and safety.

The cutting and shaping process is handled by advanced CNC and plasma cutting machines. Each duct segment is cut with extreme precision, maintaining uniform dimensions and smooth edges. This automated process ensures high consistency and eliminates human errors, which is essential when assembling long duct networks.

After cutting, our technicians move on to bending and forming the sheet metal into the required shapes, including rectangular, circular, or spiral ducts. We also fabricate transitions, elbows, reducers, and T-joints based on layout drawings. KNY Company guarantees airtight sealing and seamless fitting through accurate flanges, reinforcement stiffeners, and rubber gasket fittings.

Next comes the joining and assembly stage, where our skilled fabricators use spot welding, riveting, and lock-forming techniques to connect the duct components. For high-pressure ducts, we ensure extra reinforcement using frames and angle supports. Every joint is tested for air leakage and mechanical strength before it moves on to insulation.

For ducts exposed to extreme temperatures or noise-sensitive zones, thermal and acoustic insulation is applied using high-quality glass wool, nitrile rubber, or phenolic foam. The insulation is covered with aluminum foil or weather-resistant jacketing to ensure maximum thermal efficiency and longevity.

We also offer anti-corrosion painting and powder coating, especially for ducts used in coastal areas or chemical plants. This extends the lifespan of the ductwork and enhances its performance under harsh conditions.

KNY’s ducting fabrication service is fully customizable. Whether you need ducts for a centralized HVAC system, industrial exhaust, kitchen ventilation, or cleanroom applications, we deliver tailored solutions that match your scale and budget. Our production capacity is scalable, allowing us to handle both small-scale projects and large industrial installations with ease.

Each fabricated duct undergoes rigorous quality control checks before delivery. These include dimensional checks, leak testing, vibration testing, and coating integrity inspections. We also provide detailed documentation, layout drawings, and installation guidance to ensure smooth site execution.

Our commitment doesn’t end with delivery. KNY Company also provides on-site duct installation support, alignment assistance, and system balancing services to ensure the ducts perform optimally in real-world conditions. Our experienced site team coordinates with the MEP contractors and project managers to align fabrication with construction timelines.

In a market where reliability, accuracy, and timely delivery matter most, KNY Company stands out as a leading provider of fabricated ducting systems. Our ducting solutions enhance air distribution, minimize energy loss, and support sustainable building design—making us a trusted partner in the infrastructure and HVAC industry.
