It is cold-rolled substrate hot-dip coated in a 55 % aluminium / 43.5 % zinc / 1.5 % silicon alloy. VVS stocks DDQ at our authorised distributor yard and ships against your spec from order date.
What are the key mechanical properties of DDQ?+
Mechanical properties are reported on the mill-test certificate that ships with every coil and follow the relevant Indian/international standard. Indicative values for DDQ are captured in the spec table on this page; the brochure download has the authoritative ranges for yield strength, tensile strength, elongation and (where applicable) hardness and impact behaviour.
What dimensional range can VVS supply for DDQ?+
VVS supplies DDQ in Sheet/Plate · Coil · Slit Coil · Cut to Size. Thickness, width and length ranges are listed in the spec table above; for custom dimensions outside the standard range, use the enquiry form and a sales engineer will confirm availability within four working hours.
What documentation comes with a DDQ order?+
Every despatch includes the original mill-test certificate from Tata Steel, a tax invoice with GST, and an inspection report against your purchase order.
