Description
Galvanized sheet is a cold-rolled low-carbon base that has passed through a bath of molten zinc on a continuous hot-dip galvanizing line and then been cut to length. Zinc protects the steel in two ways: as a barrier and as an anode — at a scratch the zinc corrodes, not the steel. Technical requirements are GOST 14918-2020, GB/T 2518-2019, EN 10346:2015 and ASTM A653/A653M; base dimensions to GOST 19904-90 and GB/T 708-2019.
Details
DX51D+Z to EN 10346 and GB/T 2518 is the grade for bending and roll forming; DX52D and DX53D are for drawing and deep drawing. The nearest equivalent to GOST 14918 is sheet of 08ps steel with the zinc coating designated by weight; the American one is A653 CS Type B. Zinc weight on both sides is set by the coating class: Z100, Z140, Z200, Z275 g/m²; the higher the class, the thicker the layer and the longer the service life in an aggressive environment. The specification additionally states the spangle — normal or minimised — and the surface treatment: passivation, oiling, untreated. For subsequent painting, minimised spangle and passivation without oil are chosen.
At the mill before shipment the bureau's inspector measures the total sheet thickness with a micrometer and the zinc layer thickness with a magnetic coating gauge on both sides at several points, and checks them against the coating class from the specification and the gravimetric result in the mill certificate. Format and squareness of cut are checked; the surface is examined for uncoated areas, zinc build-up, runs, white rust and traces of corrosion. The mill test certificate (MTC) is checked against the pallet tag by heat number and coating class. The integrity of the moisture-proof wrapping is checked. The report with photographs is handed to you before shipment.

Buyer questions
How to read a mill test certificate for sheet
In the certificate (MTC) the mill states the standard and grade, heat number, thickness and format, chemical composition of the heat, mechanical test results and batch number. We check the heat number against the tag on every bundle and the marking on the sheets, and the composition and properties against the requirements of the standard named in the specification. A certificate without a heat number, or with a composition outside the limits of the standard, is grounds for not accepting the batch.
How St3sp differs from St3ps and from Q235B
St3sp is killed steel, fully deoxidised; St3ps is semi-killed. For welded structures and service at sub-zero temperatures St3sp with a category to GOST 14637 is usually specified. Q235B is the Chinese grade of the same class with a yield strength of 235 MPa minimum and an impact test at +20 °C. A mill in China issues the certificate to GB/T 700 or, under contract, rolls the plate to GOST requirements and states this in the MTC.
How sheet tonnage is calculated
Theoretical weight per square metre is 7.85 kg for every millimetre of thickness; the weight of a sheet is thickness multiplied by area and by 7.85. Actual weight differs because of the thickness tolerance: a minus tolerance makes the batch lighter than theoretical. In the specification we fix which weight the batch is settled by — theoretical or actual by weighing at the mill — and the same weight goes into the packing list.
What is checked during inspection at the mill
Thickness with a micrometer at several points of every sample sheet, width and length with a tape, flatness and squareness of cut, surface for laminations, laps and scale, marking and tags, certificate by heat and composition, packaging. For coated products — zinc or polymer thickness with a coating gauge; for stainless steel — a composition check with a portable analyser. The result is a report with photographs before shipment.
How a batch is calculated
The batch is calculated for your volume — send the specification: grade and standard, thickness, sheet format, coating and surface, quantity in sheets or tonnes, certificate requirements. From the specification we find a producing mill, agree the rolling and packaging terms and reply with a calculation.
