DX53D+Z galvanized steel coil to EN 10346 (material number 1.0951) – the deep drawing quality for parts that are formed hard and still have to carry load. Yield strength 140 to 260 MPa, tensile strength 270 to 380 MPa, elongation minimum 30% at A80.
DX53D+Z is the deep drawing grade of the EN 10346 hot-dip family, and it lands where most forming work actually sits. BOMIS supplies it as coil or cut sheet, Z100 to Z275, 0.30 to 3.00 mm thick, with the mill certificate on every coil.
The DX53D+Z is specified with a minimum elongation of 30 % at A80 and a yield range of 140 to 260 MPa and this combination is the focus of the grade. DX54D draws deeper, takes it a bit further, but costs lower strength for the extra formability, so a part that is formed twice and then has to carry load generally does better here. Think brackets, duct sections and panel stiffeners instead of a single deep cup.
The carbon is limited to 0.12% and titanium to 0.30% resulting in a substrate that is stable enough for repeat production. This matters when the formed face remains visible because zinc stretches with the steel at the bend instead of flaking. Zinc boils at a relatively low temperature, so the coated steel is scheduled for welding, not the bare sheet.

DX53D+Z goes where a part is formed hard and then has to stay rigid. Appliance plants run it for drums and liners, automotive tier suppliers for inner panels and fuel tank shells, and building work for profiled cladding and ducting. EN 10346 sets no r90 or n90 value on this grade, so if your die depends on a measured anisotropy figure rather than a tryout, DX54D is the honest answer.
Galvanising runs on our own line, so coating weight is set to your corrosion target rather than to whatever is left in the pot. Thickness holds from 0.30 to 3.00 mm and width from 600 to 1500 mm. We slit to press width or cut to sheet size in house, and lead time runs four to six weeks for standard specifications.
Coils ship with the mill certificate and edge protectors on both ends. Standard sea packing is waterproof kraft paper under a galvanised steel jacket, steel strapped, and it holds through a forty day crossing without edge rust. Eye to the sky or eye to the wall, your call.
Close, not interchangeable — the two standards describe the grade differently.

Substitution note: a swap is only valid when checked item by item against the project technical agreement and confirmed in writing.
Take DX53D when the part is formed hard but still carries load, DX54D when the draw is the hard part. Send the drawing and we will say which we would run.
For hard draws specify Z100 or Z140, because a heavier coating cracks sooner at the bend. Go to Z275 when the part then lives outdoors.
Yes. Settle which document and to which standard first, then we confirm it with production.
16 metric tons per specification, four to six weeks for standard specifications.
Both, in house — slit to press width, cut to sheet size.
