  1. 8#Galvanized slot steel waist high, H = 80.
    The thermal galvanized layer of galvanized slot steel is formed by zinc under high temperature liquid:
    1, iron -based surface is dissolved by zinc liquid to form zinc -iron alloy phase layer;
    2 The zinc ions in the alloy layer will further diffuse to the matrix to form zinc and iron dissolved layer;
    3, the alloy layer surface is bread in the zinc layer.
    If in the galvanized slot steel
    H = height
    b = leg length
    D = waist thick Arc radius
    The expansion data Galvanized slot steel Features:
    (1) A thick densely dense pure zinc layer is covered on the surface of the steel. The steel base is free of corrosion. In general atmosphere, the surface of the zinc layer forms a very thin and dense zinc oxide layer surface. It is difficult to dissolve in water, so it plays a certain protective effect on the steel substrate. If zinc oxide and other ingredients in the atmosphere generate insoluble zinc salts, the anti -corrosion effect is more ideal.
    (2) It has iron -zinc alloy layer, combined with dense, and performs unique anti -corrosion resistance in marine salt fog atmosphere and industrial atmosphere;
    (3) It has strong abrasion resistance;
    (4) Because zinc has good ductility, its alloy layer and steel base are firmly attached, so hot plating can be used for cold, rolled, brushed, bending and other types of various types. Molding without damage to the plating;

  2. 8# refers to the waist height of the slot steel, H = 80, which is 8#.
    The hot -dip galvanized slot steel, according to different galvanized processes, can be divided into hot -soaked zinc groove steel and hot -blown galvanized slot steel. Hot -galvan galvanized slot steel is a effective metal anticorrosive method. In the industry’s metal structure facilities. It is a zinc -based steel part of the steel hot -dip galvanized galvanized slot after rust removal.
    The tank steel is divided into ordinary slot steel and light slot steel. The specifications of hot-rolled ordinary slot steel are 5-40#. The specifications of hot-rolled tank steel supplied by the supply and demand agreement are 6.5-30#.
