Wrought iron fence wrought iron fence production process production process: 1, pickling treatment before the examination to check whether they have the factory piece of galvanized iron craft holes (exhaust, zinc night out, hanging), the extent of corrosion of iron surface, the surface cover can be removed by hydrochloric acid (if any paint, grease, etc. should be burned, grinding, and other methods to remove the caustic). 2, skim (caustic) equipped with a heating device, eliminating the iron surface grease, paint and so on. 3, washed with water and remove attachments alkaline iron workpiece surface. 4, pickling to remove the other surface rust, scale and other coverings. 5, after pickling inspection process: pickling effect is satisfactory, such as pickling is not sufficient, pickling again, if not complete before pickling, pickling again to be re-processed. 6, acidic water washed to remove surface iron and other attachments. 7, the fluxing agent to clean the surface again, ensure that the surface is not rust before galvanizing. 8, drying improve iron workpiece temperature to avoid excessive iron surface water, the explosion occurred in the galvanizing. 9, soaked in hot-dip zinc workpiece 440 ℃ -470 ℃ molten zinc solution, made up to a certain time after the spray rails, iron surface layer of zinc-iron alloy layers are obtained and pure zinc layer coating. 10, anti-surface passivation provides atmospheric corrosion, reduce or extend the time of white rust appears. 11, cooling the workpiece to prevent chilling retracting galvanized road barrier, resulting in a collective organization cracking. 12, finishing clear zinc plating attached to the surface of the tumor and zinc ash 13, inspection and measuring coating inspection, visual inspection of the workpiece. Here to tell you about zinc alloy guardrail installation: Features Material zinc alloy zinc alloy fence in the atmosphere is relatively resistant to corrosion, and ease of recycling. Zinc is a zinc-based alloy by adding other elements. Chang added alloying elements are aluminum, copper, magnesium, cadmium, lead, titanium and other low-temperature zinc alloys. Zinc alloy with low melting point, good fluidity, easy welding, brazing and plastic processing, corrosion in the atmosphere, materials to facilitate recycling and remelting disability; creep strength but low fence, prone to dimensional changes caused by natural aging. Preparation of melting, casting or pressure processing. Press the manufacturing process can be divided into cast zinc alloy and zinc alloy deformed. Zinc alloy with zinc alloy guardrail name suggests is to build the fence. Zinc alloy fence installation key is mounted to the fixed column, the column during installation must ensure the stability of column connections are tight, and the base and, when necessary, may be to install a solid support column. Column installation process for the application of small straight-line installation of the column were detected Iron rails, the local adjustment. Ensure smooth straight line segment, curve segments smooth. Column depth to meet the requirements of design drawings. After the column construction is completed, the supervising engineer for the column to be linear, depth, height detection, and stability as well as the underlying connection is detected. To meet the requirements before they are allowed to hang mesh construction. Only strict accordance with the design drawings for construction and installation, so linear, depth, height and other parameters meet the design needs of the column, install out of the fence is certainly qualified, will greatly increase the life of the fence.
