The answer is simply that it is difficult to directly measure the thickness accurately and precisely. INTRODUCTION: GALVANISED STEEL IRON COIL AND SHEET Galvanized sheet or coil is a process by which zinc, a non-corrosive metal, is coated over corrosive metals, such as iron and steel. Advantageous anticorrosion properties of the zinc-based coating mainly remain in the area of the properly made spot weld. %PDF-1.4 %�� same thickness (G90 [Z275] galvanize and AZ50 [AZM150] Galvalume Ò). Therefore, in certain applications, batch galvanizing of finished components can be substituted by using Z450 or Z600 coated sheet steel thereby simplifying the overall process chain. The scope of these two specifications continue to be nearly identical in terms of the types of products to be batch hot-dip galvanized, but some new language added to CSA G164 changes the primary industry or market: “This Standard specifies the requirements for zinc coating (galvanizing) by the hot-dipping process on iron and stele products intended or primarily for use in electrical and communication systemsmade from rolled, pressed, … 0000010843 00000 n 0000007040 00000 n Small differences in surface behavior may require some changes, for instance in lubrication, tooling geometry and holding forces. ≥1.0 - <1.2mm Z100 - Z275 (G30 – G90) ≥1.2 - <1.4mm Z100 - Z275 (G30 – G90) ≥1.4 - <1.6mm Z100 - Z275 (G30 – G90) Notes: Z90 may be supplied on request.
