Electroplating, Metal Polishing, Anodizing, Phosphating Metal Finishing and Powder Coating

Surface finishing is a broad range of industrial processes that alter the surface of a manufactured item to achieve a certain property. Currently, the trend is towards surface treatments. Surface engineering techniques are generally used to develop a wide range of functional properties, including physical, chemical, electrical, electronic, magnetic, mechanical, wear-resistant and corrosion-resistant properties at the required substrate surfaces. In general, coatings are desirable, or even necessary, for a variety of reasons including economics, material conservation, unique properties, or the engineering and design flexibility which can be obtained by separating the surface properties from the bulk properties. Some of common metal surface finishing technology are electroplating, electroless nickel plating, aluminium anodizing and dying, black oxidizing of copper and steel, conversion coating and passivation, pickling, heat treatment, electropolishing etc.

Electroplating is the process of applying a metallic coating to an article by passing an electric current through an electrolyte in contact with the article, thereby forming a surface having properties or dimensions different from those of the article. Essentially any electrically conductive surface can be electroplated. Special techniques, such as coating with metallic-loaded paints or silver-reduced spray, can be used to make nonconductive surfaces, such as plastic, electrically conductive for electroplating. The metals and alloy substrates electroplated on a commercial scale are cadmium, chromium, cobalt, copper, gold, indium, iron, lead, nickel, platinum group metals, silver, tin, zinc, brass, bronze, many gold alloys, lead-tin, nickel-iron, nickel-cobalt, nickel-phosphorus, tin-nickel, tin-zinc, zinc-nickel, zinc-cobalt, and zinc-iron. Electroplated materials are generally used for a specific property or function, although there may be some overlap, e. g., a material may be electroplated for decorative use as well as for corrosion resistance.

Electropolishing is used in the pharmaceutical, electronic, food, beverage, automotive, aerospace and many other industries. Pickling is the removal of oxide layers resulting from welding and heat-treating. Pickling or chemical cleaning is the chemical cleaning of metallic surfaces in order to remove impurities, stains or scale with an acidic solution. Anodizingis an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts.

With the growth in infrastructure, India will need huge amounts of metal. Aluminium is used in various sectors such as transportation, packaging, building/construction and electricity. Globally, automotive, packaging and construction sectors are the major end users of aluminium, while in India the power sector consumes most followed by automotive and housing sectors. The sector wise consumption break -up as follows: electrical-64 per cent, transport-18 per cent, packaging-4 per cent, industrial machinery-3 per cent, consumer durables-3 per cent, and steel sweetening, power and chemicals -11 per cent. There is no doubt that Indian infrastructure is poised for a great leap forward. The surface finishing industry will play an important role in constructing the Indian infrastructure.

Hot Dip Galvanizing Plant

Hot dip galvanizing is a process in which an adherent, protective coating of zinc compounds is developed on the surface of iron and steel products by immersing them in a bath of molten zinc. The protective coatings usually consists of several layers. Those closest to the basic metal are composed of iron-zinc compounds; these in term are covered by an outer layer consisting almost entirely of zinc. The complex structure of layers that comprise a galvanized coating varies greatly in chemical properties, being affected by chemical activity, diffusion and subsequent cooling. Hot dip galvanized coatings are produced on a variety of steel mill products, using fully mechanized, mass production methods. This article, however, is concerned primarily with the hot dip galvanizing of fabricated articles in manual or semiautomatic batch operations. From a modest beginning, about a century ago, the engineering industry in India has come along way and today the industry produces a stupefying range of products like plant and machinery, machine tools, power generating transmission and distribution equipments, commercial vehicles and a variety of other industrial goods and consumer durables. The significance of the engineering industry in India industrial set up stems from its forward and backward linkages with virtually all sectors. There is bright scope for new investment. Any entrepreneur can enter in this field.

HOT DIP GALVANIZING PLANT

Galvanized coatings are applied to iron and steel primarily to provide protection against corrosion of the basis metal. Hot Dip Galvanizing is a process in which an adherent, protective coating of zinc and zinc compounds is developed on the surfaces of iron and steel products by immersing them in a bath of molten zinc. The protective coatings usually consist of several layers. Those closest to the basis metal are composed of iron-zinc compounds these in turn are covered by an outer layer consisting almost entirely of zinc. The complex structure of layers that comprise a galvanized coating varies greatly in chemical composition and physical and mechanical properties, being affected by chemical activity, diffusion, and subsequent cooling. Small differences in coating composition, bath temperature, time of immersion, and rate of cooling or subsequent reheating can result in significant changes in the appearance and properties of the coating. Hot dip galvanized coatings are produced on a variety of steel mill products, using fully mechanized and mass production methods. Hot dip galvanized zinc coatings have their longest life expectancy in rural areas where sulfur dioxide and other industrial pollutant concentrations are low. These coatings also give satisfactory service in most marine environments. Although the life expectancy of hot dip galvanized coatings in more severe industrial environments is not as long as for less aggressive environments, the coatings are still used extensively in those exposures, because in general, no more effective and economical method of protection is available. India's steel pipe industry is primarily engaged in manufacturing seamless or welded steel pipes or tubes or ferrous metal pipes or tube fittings. Steel pipes are primarily of two types, seamless and welded. Other specific types extend the basic classification to include: (a) cast iron pipes, (b) stainless steel tubes, (c) ERW (electric resistance welding) steel pipes, (d) galvanized pipes, (e) API pipes, (f) SAW (submerged arc welded) pipes, and (g) spun pipes. Welded steel pipes include a wide variety of pipes and tubes. Welded pipes are normally manufactured from HR and CR coils by ERW. Galvanized pipes are zinc-coated to prevent corrosion. ERW tubes are meant for high performance applications, such as trusses and columns in housing, industrial and construction sectors, chassis for two-wheelers and light commercial vehicles, propeller shafts and axles. According to observation of engineering goods statistics, we can conclude about the essentiality of the galvanizing process as companys work or on the job work base. It can be concluded that galvanization process is partially proportional to the increase of demand of the engineering goods or most or ancillary item production the steel base. It can be concluded that demand of galvanizing industries will be increased 10% per annum. On that base it can be predicted that there is good scope for galvanizing industries as job work base.

Transmission Towers & Tele Communication Towers With Galvanizing Plant

A transmission tower (colloquially termed an electricity pylon in the United Kingdom and parts of Europe, an ironman in Australia, and a hydro tower in English Canada) is a tall structure, usually a steel lattice tower, used to support an overhead power line. They are used in high voltage AC and DC systems, and come in a wide variety of shapes and sizes. Typical height ranges from 15 to 55 metres (49 to 180 ft), though the tallest are the 370 m (1,214 ft) towers of a 2700 metres long span of Zhoushan Island Overhead Powerline Tie. In addition to steel, other materials may be used, including concrete and wood. The products of the Proposed Fabrication units are covered by well designed and fabricated structures for a. state electricity boards for the purposes of electricity supply (i,e) a) power transmission Towers, TV and Radio Towers, Telecommunication Towers, b) Railway and Highway bridges etc. c. Industrial structures etc. Some transmission towers combine these basic functions. Transmission towers and their overhead power lines are often considered to be a form of visual pollution. Methods to reduce the visual impact include undergrounding. Tower structures can be classified by the way in which they support the line conductors. Suspension structures support the conductor vertically using suspension insulators. . Strain structures resist net tension in the conductors and the conductors attach to the structure through strain insulators. Dead end structures support the full weight of the conductor and also all the tension in it, and also use strain insulators. Where the conductors are straight, a tangent tower is used. Angle towers are used where a line must change direction. Structures are classified as tangent suspension, angle suspension, tangent strain, angle strain, tangent dead end and angle dead end.

Corrugated Galvanized Sheet

In the manufacturing of automobiles the quality of the sheet metal as supplied, has remarkable a decided influence upon the quality of the painted car body. Here the concept of quality comprehends the properties such as corrosion resistance, adherence and decoration. already the metal sheet as supplied must corresponds to determine specifications in relation to chemical analysis, spring back index, and the surface roughness. In spite of the correction of the following specification, the different charges of steel sheet during the drawing process behave quite differently, because steel or on case, steel sheet is in no way a homogenous substance with always having the same properties, but it is a multi-larger material, affected with certain characteristics and defects. . Most products, manufactured from the constructional grades of steel, are sold in highly competitive market, whether the product is a wrench, automobile farm tractor, or mammoth mining shovel. Manufacturers of steel products vary greatly in their technical backgrounds. Most reputated firms, however, have at least an adequate technical background by virtue of education, experience or both. In any event the common engineering characteristics of steels, both "as rolled" as heat-treated are generally readily accessible in various technical libraries and from the steel producer themselves Uses and Applications The corrugated galvanized iron sheets are extensively used in various fields e.g. industries sheds, dairy farm sheds, poultry farm sheds etc. for roofing purpose. In recent years, a lot of multi scale projects have taken up the Indian industry by a storm and these levels have given a larger scope for steel companies. The galvanised plain coils / sheets and corrugated sheets (GP/GC) are value - added steel products which are tough, sturdy, light weight, bright and corrosion resistant. In India these are produced in the thickness range of 0.15 mm to 2.0 mm and width range of 800 mm to 1560 mm. The function of the zinc layer is mainly three fold: To retain the steel intact with its full initial strength; to provide the surface a more pleasing appearance and to increase the life of any suitable organic finishing system applied over it. Market Survey There is always a need for galvanized sheets, rollers, and other varieties of pressed sheets that make up the steel industry. The construction process needless to say remains the same but has new implementations that are adapted from the western counterparts. Steel manufacturers are now in demand for infrastructure and automobile sectors as well, thus widening their scope of development. The recent growth of these newly developed industries has given a new lease of hope to steel developers. This sudden splurge of industrial growth has honed the success of the leading steel companies in India. Roofing industry in India is preparing for the next generation of ambitious projects. Growth in the infrastructure and industrial segment has been a major demand driver for roof and wall cladding industry. It has registered a double digit growth over past three years and the future of this industry is also looking bright considering the low steel penetration and high demand in construction industry. Major shift is observed from clay tiles and conventional roofing system to metal cladding solution. Customers are looking for architectural solution which provides innovative shapes such as convex, concave in addition to new attractive colors. The future of roof and wall cladding industry is bright considering the low steel penetration and high demand in construction industry. Few Major Players are as under:- Bharat Berg Ltd.
