Cold rolled Steel
![](index_files/1page-img3.jpg)
Cold rolled steel is a mill product produced from a hot-rolled pickled coil that has experienced substantial cold reduction at room temperature. The usual end product is characterized by improved surface, greater uniformity in thickness, and improved mechanical properties as compared with hot-rolled sheet. This occurs when the metal below its re-crystallization temperature, which increases the strength via strain hardening up to 20%.
Cold rolled steel in normally available in four types: commercial steel, drawing steel, extra deep drawing steel, and extra deep drawing steel plus. Drawing steels are more ductile.
Galvanized Steel

Galvanized steel is steel that has gone through a chemical process to keep it from corroding. The steel gets coated in layers of zinc oxide because this protective metal does not get rusty as easily. The coating also gives the steel a more durable, hard to scratch finish that many people find attractive. For countless outdoor, marine, or industrial applications, galvanized steel is an essential fabrication component.
One of the most common ways of making steel resist rust is by combining (alloying) it with a metal that is less likely to corrode: zinc. When steel is submerged in melted zinc, a chemical reaction permanently bonds the zinc to the steel.
Prepainted Steel

PPGI is pre-painted galvanized 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 Galvanized 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.
Corrugated Sheet

Corrugated Sheet is made up of color coated sheet, galvanized sheet, and other metal steel sheet after rolling cold bending into a variety.
Advantages: a) attractive and innovative appearance, rich colors, decorative, flexible combination, can express a different architectural style; b) light weight, high mechanical properties;
Application: a) industry and civil building, warehouse; b) steel structure house and mobile house, roof and interior & exterior decoration etc. for more details at Corrugated Color Steel Sheet
Tinplate
Tinplate, thin steel sheet with a coating of tin applied either by dipping in molten metal or by electrolytic deposition; almost all tinplate is now produced by the latter process. Tinplate made by this process is essentially a sandwich in which the central core is strip steel.
This core is cleaned in a pickling solution and then fed through tanks containing electrolyte, where tin is deposited on both sides. As the strip passes between high-frequency electric induction coils, it is heated so that the tin coating melts and flows to form a lustrous coat. The end product has a tin...
Color Stainless Steel
Customized Color Stainless Steel, When stainless steel is specified there is no reason to limit the color choice to golden. A wide range of both opaque and translucent colors is available. The underlying finish texture can remain visible and add to the aesthetic appeal. Stainless steel superior corrosion resistance makes colored stainless steel an excellent, sustainable materials choice for following demanding applications.
Color Stainless Steel products are mainly applied in construction, elevator industries as well as in hotel, restaurants and apartment decoration
Steel Pipes

Steel Casing Pipe, also known as encasement pipe, is most commonly used in underground construction to protect utility lines of various types from getting damaged. Such damage might occur due to the elements of nature or human activity.
Steel casing pipe is used in different types of horizontal underground boring, where the pipe is jacked into an augered hole in segments and then connected together by welding or by threaded and coupled ends, or other proprietary pipe connectors. The steel casing pipe can also be set up and welded into a "ribbon" and then directionally pulled through a previously drilled hole under highways, railroads, lakes and rivers.
Wire, Wire mesh

Welded wire mesh, or welded wire fabric, or "weldmesh" is an electric fusion welded prefabricated joined grid consisting of a series of parallel longitudinal wires with accurate spacing welded to cross wires at the required spacing.
The welded wire mesh is a metal wire screen that is made up of low carbon steel wire or stainless steel wire. It is available in various sizes and shapes. It is widely used in agricultural, industrial, transportation, horticultural and food procuring sectors. It is also used in mines, gardening, machine protection and other decorations.
