DSQ Plates for Galvanizing Tank Fabrication – High Formability with IS 8917 Quality
Looking to fabricate a galvanizing tank that can withstand high temperatures, continuous acid exposure, and long hours of immersion cycles? Hindustan Steel Corporation supplies DSQ Plates (Dead Soft Quality) specifically suited for galvanizing tank fabrication—as per IS 8917:1978, with precise flatness, soft temper, and chemical resistance.
Unlike structural grades like IS 2062 E250 or ASTM A36, DSQ is engineered to fold, press, or curve into tank shapes without cracking. Whether it’s zinc tanks, degreasing chambers, or flux tanks, DSQ plates offer the perfect combination of softness and process compatibility.
For galvanizing tank manufacturing, the right steel must have:
DSQ Plate meets all these criteria. It is a non-structural steel meant for vessels that need shape retention, corrosion resistance, and weldability—not heavy load-bearing.
DSQ plates are widely used in:
Tanks are usually fabricated using 3 mm to 12 mm DSQ plates—laser-cut and folded to exact tank dimensions.
| Property | Typical DSQ Value (Tank Grade) |
|---|---|
| Yield Strength | ~240 MPa |
| Tensile Strength | 370–410 MPa |
| Elongation | 22–26% |
| Hardness | ~120–130 BHN |
| Cold Workability | Excellent |
| Weldability | MIG, TIG, SMAW compatible |
| Surface Coating | Ideal for epoxy, rubber lining, acid-resistant paints |
DSQ’s dead-soft temper allows for clean press-bending, curved corners, and minimal weld distortion, ensuring longer tank life with no leakage risk.
We supply both Indian and global equivalents, including:
Available in shot-blasted, primer-coated, and quenched & tempered (Q&T) finishes.
For tank fabrication in India, the preferred standard is:
DSQ is not a structural plate—its purpose is to be shaped, lined, and welded with chemical resistance
Most galvanizing tanks are fabricated in mild steel DSQ plates ranging from 3 mm to 12 mm.
| Component | Recommended Thickness |
|---|---|
| Bottom Shell | 6–12 mm |
| Side Walls | 5–8 mm |
| Corner Folds | 4–6 mm (with soft bend radius) |
| Tray Linings | 3 mm |
| Baffle Plates | 4 mm |
| Reinforcement Plates | 8–10 mm |
Plates are available in 1250 mm, 1500 mm, and 2500 mm widths, with lengths up to 6.3 meters or custom size
DSQ plates offer superior behavior in cold bending, which is essential for seamless tank joints and shaped corners
Fabrication Recommendations:
DSQ behaves like butter under tooling—no cracking, flaking, or edge deformation during forming.
DSQ plates can be lined and coated easily:
| Process | Compatibility |
|---|---|
| MIG Welding | Excellent |
| Rubber Lining | Fully compatible |
| Epoxy Coating | Excellent adhesion |
| Glass Flake / FRP | |
| Pickling / Degreasing | (with lining) |
DSQ can also be fabricated with double-skin lining or thermal insulation cladding on demand
HSC is one of India’s only suppliers to offer DSQ plates specifically tailored for galvanizing plants:
We support not just plate supply but full project coordination, including drawing assistance and packaging for container fitment.
You may also consider these materials depending on your galvanizing setup:
| Material | Use Case |
|---|---|
| DSQ Plate (IS 8917) | Press-formed tanks, lining-ready |
| ASTM A283 C | Global equivalent, soft-forming |
| SS316L | Internal shell for aggressive chemical exposure |
| DSQ + FRP Coated | For high-acid or thermal tanks |
| DSQ + Rubber Lining | Ideal for HCl, sulfuric acid tanks |
Need internal shell + outer cladding? We offer DSQ + stainless steel dual-grade supply on project basis
Hindustan Steel Corporation is a trusted exporter of DSQ plates for galvanizing tank projects in:
Export Packaging Includes:
We also arrange SGS, BV, DNV, or TUV inspection for cross-border galvanizing plant commissioning.
Here’s a buyer-friendly guide:
| If You Need… | Choose… |
|---|---|
| Basic zinc tanks | 6 mm DSQ HR plates |
| Complex ducting tanks | 4 mm DSQ with bend test approval |
| Dual lining compatibility | Pickled & oiled DSQ |
| U-bend tanks | DSQ with guaranteed bend radius |
| Long-term coating stability | Shot-blasted DSQ plate |
Always select DSQ grade confirmed to IS 8917 for forming-heavy fabrication
Each consignment of DSQ plates from HSC comes with:
We support full project documentation for EPC, plant commissioning, or fabrication tendering.
Typically 5–8 mm for side walls, 6–12 mm for base plates.
It’s the Indian standard for deep drawing mild steel used in formable applications like tanks.
Yes. With proper lining, DSQ is ideal for HDG tanks.
Use multiple weld passes and stress-relieve after welding.
Yes, it’s fully compatible with rubber and epoxy linings.
2.5 to 3 times the thickness is recommended.
Yes. Pickling, shot blasting, or oil removal is advised.
No. DSQ is softer, meant for formability, not structural strength.
A283 Gr C is the global equivalent; DSQ is Indian standard (IS 8917).
Yes, it cuts cleanly on both machines.
MTC, IS 8917 confirmation, TPI, and QA reports.
Yes, to UAE, Africa, South Asia, and beyond.
Yes. We provide samples and bend test validation.
Yes. We assist with plate optimization and fabrication drawing support.
