PRECAUTIONS channel storage when: 1. The channel open dumps should stoop to put that mouth down, I-beam shall stand up, I can not groove face up Japanese standard steel channel specification sheet, in order to avoid stagnant water Rusty, principle requires stacking under palletizing firm, to ensure safe conditions, so according to variety, size palletizing Japanese standard channel specification standard, different varieties of materials to be separately stacking, to prevent confusion and mutual corrosion ban stack bits are stored in the vicinity of corrosive effect on steel items. 2. open dumps steel, the following must be wood or stone JIS pad channel size, stack surface is slightly inclined to facilitate drainage, and note that the material placed flat to prevent bending deformation caused by stacking height, manual operation not more than 1.2m, mechanical work no more than 1.5m Japanese standard channel, stack width is not more than 2.5m. Due to defects in the process of galvanizing, zinc coating the surface of zinc particulate sometimes raised, which is dross particles affect the appearance of the coating, but does not affect the corrosion resistance. In recent years, mostly due to the steel silicon killed steel, prone to gray matte coating, namely zinc plated surface is not shiny and gray, severe dark gray, which is an iron-zinc alloy layer caused by the exposed surface against atmospheric Corrosion has no effect. Plus nickel and zinc plating process change may reduce or eliminate the appearance of dark zinc plating bath. However, the silicon content is particularly high in low-alloy steels such as high strength steel, at home and abroad can not completely eliminate this phenomenon.
