About Fabricated Duct Spacers

Duct Spacers shall be made from ABS Acrylonitrile Butadiene Styrene (ABS). (1.04 specific gravity

has been chosen by TECAFINE for the manufacture of all interlocking module spacers

because of its flexibility, strength, and resiliency.

(A) Under compressive stress

(B) The spacer modules can be freely handled on the job site without breakage.

Since many utilities install underground systems year-round, and most large projects carry through more than one year, it is important to use a formulaon of ABS for spacers that will not be adversely by the extremes of summer or winter temperares. Finally, Rib wall construction makes it possible to design a spacer which will hold safely the vertical

loads normally encountered when men work atop large duct banks.

Spacers shall consist of interlocking modules. The interlocking modules shall include an

internal vertical channel on both side edges of the spacers. When the duct bank is

assembled.

Superior Corrosion & Fire Resistance

All duct spacers feature a premium hot-dip galvanized finish ensuring high corrosion resistance, and are manufactured to comply with strict IS/BS fire resistance standards. This safeguards HVAC and industrial air supply systems over prolonged service lives, even in harsh environmental conditions.

Precision Engineering & Customizability

Every spacer is produced with a tolerance of 1 mm and deburred, smooth edges for safe handling. With customizability in size, material grade, thickness (1.2 mm to 3 mm), and profile shape, customers receive solutions optimally tailored to specific ductwork requirements.

Efficient Mounting & Secure Packing

Mounting options include clamp or fixed installation on duct flanges, with channel or serrated section shapes. Our production process ensures each bundle is wrapped in stretch film for protection during transit and storage, maintaining finish quality and component integrity.

FAQ's of Fabricated Duct Spacers:

Q: How are fabricated duct spacers installed for HVAC applications?

A: Fabricated duct spacers are easily mounted using clamp or fixed methods on duct flanges. Connection options such as tab, clamp fixing, spot welding, or mechanical joints ensure secure and stable installation in duct systems.

Q: What makes these duct spacers resistant to corrosion and fire?

A: The spacers are made with a hot-dip galvanized finish (zinc coated) and are built from G.I. Grade-80/120 GSM steel, providing high corrosion resistance. Compliance with IS/BS fire standards further ensures safe use in demanding environments.

Q: When should custom sizing or material grades be specified when ordering?

A: Custom specifications for size, material grade, thickness, and profile should be provided at the ordering stage to ensure spacers precisely match your duct system's requirements and operational conditions.

Q: Where are these duct spacers typically used?

A: They are commonly used in HVAC duct systems, industrial air supply networks, and any situation requiring precise duct spacing and rigidity, operating within an atmospheric pressure range and -10C to 90C temperature window.

Q: What is the process for ensuring uniform, high-quality finishes?

A: After fabrication, each spacer undergoes deburring for smooth edges and is then hot-dip galvanized. A uniform, scratch-free, silver finish is maintained, and quality is confirmed through inspection and RoHS compliance checks.

Q: How do these spacers benefit ductwork performance?

A: By maintaining consistent duct spacing and rigidity, these spacers reduce vibration, prevent sagging, and enhance air flow efficiency, ultimately extending the operational lifespan of duct systems.
