What thicknesses are available in Dead Soft Quality Steel?
DSQ (Dead Soft Quality) plates are manufactured to meet exceptional bending, forming, and ductility requirements — and that begins with precise control over their thickness. At Hindustan Steel Corporation, we supply DSQ plates in a wide range of thicknesses suitable for galvanizing tanks, chemical storage vessels, pickling lines, and heavy press-formed fabrications.
Standard supply thickness ranges from 3 mm to 50 mm, with customized options available upon request. Whether you require ultra-thin plates for high ductility or thick plates for structural tank bottoms, our in-house cutting and leveling services ensure you get the exact thickness your fabrication demands.
Standard Thickness Ranges Available
We stock DSQ steel plates in the following standard thickness brackets:
- 3 mm to 5 mm – Ideal for small tanks, ducting, liners
- 6 mm to 12 mm – Most preferred range for galvanizing tanks, vessels
- 14 mm to 25 mm – Used for heavy-duty acid and chemical containers
- 26 mm to 50 mm – For tank bottoms, base plates, or custom structures
Need a size outside this range? We also offer cut-to-size DSQ plates and can arrange plasma or waterjet cutting with minimal deformation.
