UL. FR. LONDZINA 61, 43-246 STRUMIEŃ, POLAND TRANSPORT AND STORAGE CONTAINERS HOT-DIP GALVANIZING PLANT JOB OFFERS CONTACT Chemical composition Hot-dip galvanizing enables the anti-corrosive zinc coating to be applied to steel structures with a silicon (Si) content lower than 0.03% or in the range 0.15% - 0.25%. Surface condition The surface of the structure should be free of scale, a thick layer of rust, welding spatter, welding slag, silicone anti-spatter, contamination with paints, greases and oils. Structure dimensions The structure dimensions must be smaller than the working dimensions of the galvanizing bath - 10.2 x 1.4 x 2.7 m (length x width x depth). For two dimensions close to the limit, prior consultation is required. Features of the structure Structures should be able to be suspended with wires or chains under the traverse. The shape of the structure should allow free flow of liquid zinc to all spaces and its free outflow. Mutual proportions of materials of different thickness welded together should not exceed 4: 1. Galvanization of structures with large surfaces of thin, unreinforced sheets should be avoided due to the risk of corrugation. Venting openings Structures made of closed-section elements should be provided with venting openings allowing free inflow of liquid zinc during immersion and its free outflow when the structure emerges from the zinc bath. The table below shows the size and number of vent holes in the construction elements. internal dimensions of the closed profile in mm less than: minimum diameter of holes in mm in opposite ends of the profile and their number: round square rectangular 1 2 3 15 15 20 x 10 8 20 20 30 x 15 10 thirty thirty 40 x 20 12 10 60 60 80 x 40 20 12 10 60 60 80 x 40 20 12 10 80 80 80 x 60 20 18 12 100 100 120 x 80 25 20 12 120 120 160 x 80 thirty 25 16 160 160 200 x 120 40 25 16 200 200 260 x 140 50 thirty 16 The vent holes can be made as triangular or semicircular cuts in the profile walls.
