(1) Workpieces with low deformation tendency.
Such as hot-rolled angle steel, channel steel, I-beam, round steel, steel pipe and other sections or workpieces made of steel; corrugated plates, grating plates, and workpieces whose structural units are thick steel plates (δ Greater than or equal to 16.00 mm), etc.
(2) Workpieces with medium deformation tendency.
Thin-walled reels, thin-walled long tubes, workpieces with asymmetric distribution of welds in the structural unit and large differences in material thickness between adjacent parts, workpieces with medium-thick steel plates (δ=8.00~16.00 mm) as the structural unit, etc.
(3) Workpieces with high deformation tendency.
For example, workpieces with relatively large appearance specifications and structural units of thin steel plates (generally referring to plate structural parts with δ Less than or equal to 8.00 mm or less. The shape and surface area of the workpiece have a great influence on the performance of hot-dip galvanizing), such as patterned plates, thin Platforms composed of steel plates and shaped steel frames, as well as other workpieces with long specifications but extremely asymmetrical cross-sectional shapes, etc.
