In-House Duct Fabrication
Every duct, fitting, and structural support frame is manufactured directly in our Ahmedabad facility under stringent internal quality control.
Quality Built on Our Shop Floor
Outsourcing ductwork to third-party vendors often introduces dimensional errors, weak flange seals, and site delays. At Phalange Industries, we control quality at the source in our Vatva, Ahmedabad workshop.
Using prime-grade Galvanized Iron (GI), Stainless Steel (SS304/SS316), and Mild Steel (MS), our skilled fabricators craft rectangular and spiral ductwork according to SMACNA and IS standards.
Quality Standards
- SMACNA Compliant Duct Gauges (18G to 24G)
- Prime Galvanized Steel (Zinc Coating 120-275 gsm)
- SS 304 / SS 316 Food & Pharma Grade Sheet
- Leakage Class C Certification Capability
- Pre-dispatch Dimensional & Squareness Check
- Anti-corrosion Primer Coating for MS Supports

Frequently Asked Questions
What sheet metal materials and gauges do you fabricate in your Vatva workshop?
We fabricate Galvanized Iron (GI), Stainless Steel (SS 304 / SS 316), and Mild Steel (MS) ductwork ranging from 18-gauge (1.2mm) heavy-duty industrial ducts to 24-gauge commercial air ducts, conforming to SMACNA standards.
What are the advantages of companion flange (TDC/TDF) ductwork over conventional C-cleats?
Companion flange (TDC/TDF) ductwork features integrated roll-formed flanges with corner slide gaskets, offering superior mechanical rigidity, faster field assembly, and Class C low leakage rates compared to traditional slide C-cleats.
Do you manufacture custom dampers, AHU frames, and weather louvers?
Yes, our shop floor fabricates custom Volume Control Dampers (VCDs), motorized fire dampers, sound attenuators, MS equipment skids, and heavy-duty weather louvers tailored to exact dimensions.
