Proper ductwork fabrication is crucial for the optimal functioning of HVAC systems that provide conditioned air throughout a building. It involves the creation of ducts that meet precise specifications such as size, shape, material selection, airflow, and pressure requirements.
For businesses in the Philippines, partnering with a reputable ductwork manufacturer is essential. Here are some key reasons why ductwork fabrication plays a vital role in the HVAC industry in the Philippines.
Our duct production line includes coil feeding, shear cutting, grooving, lock forming and hydraulic bending. These stages prepare and form the sheet material used in fabrication.
The fabrication requirements depend on the duct type and project specifications. Include any specified joints, connections or finishing requirements with your enquiry.
The first step in ductwork fabrication is to design and measure the space where the ductwork will be installed. In F.R. Sevilla, we work with our trusted consultants to craft designs based on the measurements provided by clients.
Once the design is finalized, the next step is to select the appropriate materials for the ductwork system. This may include galvanized steel, aluminum, or other materials, depending on the requirements of the system and the specific building needs.
The selected materials are then cut and shaped into the appropriate pieces required for the ductwork system. This may involve the use of specialized equipment such as cutting machines, bending machines, and other tools.
The individual pieces of ductwork are then assembled into the complete ductwork system. This may involve welding, riveting, or screwing the pieces together, depending on the materials and design of the system.
Depending on the building requirements, the ductwork may need to be insulated to prevent heat loss or gain. This involves wrapping the ductwork in insulation materials such as fiberglass or foam.
Once the fabrication is complete, the finished ductwork system is inspected to ensure that it meets the required standards for quality, safety, and functionality.
We use the SMACNA Duct Construction Standard for duct fabrication. Send the applicable project specifications, including any required standard edition, pressure class, joint details or inspection requirements, for review before an order is confirmed.

F.R. Sevilla is a leading ductwork manufacturer in the Philippines that specializes in the production of rectangular ducts made of high-quality galvanized steel. We manufacture these in different sizes, depending on the requirements of each project.
In addition to rectangular, we also offer round ducts made of the same materials. These round ducts are designed to provide efficient and reliable airflow, making them ideal for a wide range of building types, including commercial, industrial, and residential buildings.
We also manufacture the dampers used in the ductwork. These play a critical role in regulating the airflow in a system. There are three main types: volume control, smoke, and fire.
At F.R. Sevilla, we go beyond being a ductwork manufacturer in the Philippines by also fabricating the support and accessories required for our clients. Our manufacturing plant is also equipped with plating services to complete the process.
A clear drawing set and quantity schedule help our team assess the scope and production requirements. Include the following information where available:
Duct layouts or fabrication drawings with revision numbers
Rectangular or non-spiral round, with cross-sectional dimensions and lengths
Sheet material, grade or specification, and thickness
Straight ducts, fittings and accessories, listed separately
Applicable specifications, connection details and required documentation
Project site, required date and any phased delivery requirements
Identify the fabrication, delivery or installation work you want included for review
Production lead time depends on duct size and quantity. Share your required date with the drawings and quantity schedule so the team can assess the timing for your order.
Contact F.R. Sevilla with your drawings, specifications and quantities to discuss duct fabrication for your project. If some details are still being developed, identify them in your enquiry so the team can clarify what is needed for a quotation.
For a wider project scope, explore our HVAC contracting services.
When recommending ductwork, factors such as building size, HVAC system type, number of occupants, airflow requirements, and heat load are considered to ensure efficient performance and occupant comfort.
Yes, ductwork can be relocated or modified if changes need to be made to the building layout or HVAC system. A professional HVAC contractor can assess the system and determine the best course of action.
As a leading ductwork manufacturer, we recommend evaluating and considering the replacement or refurbishment of old ductwork if it exhibits significant damage, such as leaks, corrosion, or insulation deterioration. If your ductwork is over 15-20 years old and no longer meets modern performance standards, it may be time to consult with us to explore our high-quality ductwork solutions. Our expertise and range of products can help optimize your HVAC system's efficiency and ensure superior indoor air quality.
