Have set up counting poles on the wall corners, ladder and the corners between external and internal walls.
在墙转角处、楼梯间及内外墙交接处，已按标高立好皮数杆；
The internal and external stifferers, baffles, diaphrams, gussets etc. should have the corners cropped to aid the flow of molten zinc.
内外部的加强筯，折流板，膜板，三角板等都应该倒角以方便锌水流动。
