PPGI is pre-painted galvanised iron, also known as pre-coated steel, coil coated steel, color coated steel etc, typically with a hot dip zinc coated steel substrate. The term is an extension of GI which is a traditional abbreviation for Galvanised Iron. Today the term GI typically refers to essentially pure zinc (>99%) continuously hot dip coated steel, as opposed to batch dip processes. PPGI refers to factory pre-painted zinc coated steel, where the steel is painted before forming, as opposed to post painting which occurs after forming. The hot dip metallic coating process is also used to manufacture steel sheet and coil with coatings of aluminium, or alloy coatings of zinc/aluminium, zinc/iron and zinc/aluminium/magnesium which may also be factory pre-painted. While GI may sometimes be used as a collective term for various hot dip metallic coated steels, it more precisely refers only to zinc coated steel. Similarly, PPGI may sometimes be used as a general term for a range of metallic coated steels that have been pre-painted, but more often refers more precisely to pre-painted zinc coated steel. Zinc coated steel substrate for PPGI is typically produced on a continuous galvanising line (CGL). The CGL may include a painting section after the hot dip galvanising section, or more commonly the metallic coated substrate in coil form is processed on a separate continuous paint line (CPL). Metallic coated steel is cleaned, pre-treated, applied with various layers of organic coatings which can be paints, vinyl dispersions, or laminates. The continuous process used to apply these coatings is often referred to as Coil Coating. The steel thus produced in this process is a prepainted, prefinished and ready for further processing into finished products or components. to use material.

Citric Acid is an acidic compound from citrus fruits; as a starting point in the Krebs cycle, citrate is a key intermediate in metabolism. Citric acid is one of a series of compounds responsible for the physiological oxidation of fats, carbohydrates and proteins to carbon dioxide and water. Used to prepare citrate buffer for antigen retrieval of tissue samples; the citrate solution is designed to break protein cross-links; thus, unmasking antigens and epitopes in formalin-fixed and paraffin embedded tissue sections, resulting in enhancing staining intensity of antibodies. Citrate has anticoagulant activity; as a calcium chelator, it forms complexes that disrupt the tendency of blood to clot. May be used to adjust pH and as a sequestering agent for the removal of trace metals.
Cold rolling is a metallurgical process in which metal is passed through a pair of rollers at a temperature below its recrystallization temperature. This process hardens the metal, by compressing and stretching the metal crystals. During the rolling process, the metal is annealed by heating it above the recrystallization temperature after every few rollings, to prevent it from becoming brittle and cracking. Cold rolled metal is given a “temper” rating based on the degree it was compressed. “Skin-rolled” metal undergoes the least rolling, being compressed only 0.5-1% to harden the surface of the metal and make it more easily workable for later processes. Higher ratings are “quarter hard,” “half hard” and “full hard”; in the last of these, the metal is compressed by 50%. Metal hardened by cold rolling can bend without breaking, although ductility decreases as the hardness increases. Quarter hard metal can be bent entirely back on itself, while full hard can only be bent 45°.
Hot rolled products are available in five product groups:
Single-reduced TMBP is available in a wide range of sizes; double-reduced TMBP is also available. TMBP is available in a wide variety of surface finishes. TMBP is classified according to specification, steel type, temper designation, annealing method, surface finish, and other characteristics.

MSG is a food additive. Its full name is mono sodium glutamate and it comes from the amino acid, glutamic acid. Amino acids are the building blocks of protein; our food and bodies contain protein that, in turn, contains glutamate. Glutamate is found in a wide variety of foods. MSG use Glutamate helps enhance the flavor of food, so glutamate is often deliberately added to foods — either as MSG, hydrolysed protein or a variety of food ingredients rich in glutamate, such as cheese, tomato pastes, stocks and sauces. MSG cannot improve inferior quality food or make up for poor cooking practices. It does not allow a cook to substitute low-quality for high-quality ingredients in a recipe, and does not tenderise meat. MSG simply enhances the savoury flavors already present in food.
Citric acid anhydrous is produced as translucent crystals and as white crystalline powder. It is odorless and has a strong acidic taste. Citric acid anhydrous is very soluble in water and freely soluble in alcohol. Storage in tight containers away from heat and humidity (75oF and 55% RH) is recommended. Citric acid is widely used in the food, beverage, and pharmaceutical industries to impart a clean, refreshing tartness. Its prime use is as an acidulant, but it is also used as sequestrant of metal ions to give protection from the development of off-flavors and off-odors in certain foodstuffs. A major industrial use of citric acid is in the manufacture of ecologically compatible detergents. It is also used in chemical cleaning, concrete admixtures, plasticizers, and a range of other applications.
