DSQ Plates (Dead Soft Quality Plates) are used in critical fabrication jobs that require high ductility, deep drawability, and exceptional weldability. These plates are designed to bend, shape, and form easily without cracking—making them indispensable in industries like galvanizing, chemical storage, pickling, and tank fabrication.
Unlike standard structural steels, DSQ steel plates do not resist forming—they cooperate with it. That’s why engineers prefer DSQ for creating cylindrical tanks, curved ducts, acid lines, and pressure-free chemical vessels.
Top Industries Using DSQ Plates
- Galvanizing Plants – For lining tanks exposed to zinc baths
- Acid & Chemical Storage – Resistance to corrosion & cracking
- Electroplating Units – Deep drawn vessels, cathode lines
- Pickling Plants – High formability in acid-wash setups
- Ventilation Ducts – Smooth curve fabrication with no tearing
- Automotive Tooling – In dies and non-load bearing press tools
- Fabricated Vessels – Cylindrical, square, rectangular tanks
Mechanical Properties for Fabrication Use
- Yield Strength: Approx. 240–260 MPa
- Tensile Strength: 410 MPa min
- Elongation: ≥ 28%
- Bend Radius: 0T–1T (for 180°) – excellent for ducting
- Hardness: Soft, ideal for press brake operations
Chemical Composition (Typical for DSQ as per IS 8917:1978)

DSQ Plate as per Indian Standards
Manufactured as per IS 8917:1978, DSQ plates are certified for applications where steel must undergo forming without compromising structural integrity. These are non-structural, non-load bearing plates suitable for tanks, vessels, and cladding jobs.
