Steel Expanded Metal With Raised & Flattened Type Steel expanded metal is produced from one steel plate or roll through simultaneously slitting and stretching, which forms a wide array of diamond shaped openings with uniform sizes. During the expanding process, the metal can be expanded up to ten times its original width, losing up to 80 % its weight per meter, and becomes more rigid. It is lighter, less expensive than a single metal sheet, and also allows for free flow of liquid, heat, air and sound, yet producing impenetrable barrier to larger solid objects (or persons). Compared with the traditional flat metal sheet, steel expanded metal has more notable advantages for its versatile applications. More and more new applications are found for it in the family, office, and other industrial, commercial fields. How is steel expanded metal made? Steel expanded metal is manufactured by a process of shearing and stretching under a precisely programmed machine, which produces precise apertures but stretches the metal sheet (See more details in Technology). Different specifications can be made by changing the material or the expanded style. Two types of expanded metal Steel expanded metal is manufactured in two ways: raised expanded metal and flattened expanded metal. Raised expanded metal is also known as standard expanded metal, it has diamond openings with slightly raised surface. Flattened expanded metal is manufactured by passing the standard expanded sheet through a cold roll reducing mill, forming diamond openings with flat surface. Features One piece and single unit construction. Less weight and more economic than regular metal sheet. Extensive range of materials to suit any application. It is rigid for protective uses, while providing decorative effect. High quality for durable use. The most economical option among all metal materials. Easy to install.
In building construction, the costs of aluminum formwork has account 20%-30% for the total costs, when removed the aluminum formwork, it account 5-50% total time. Compare with the traditional timber form work, the aluminum formwork has obvious advantages. 1.Easy 2.Efficient 3.Saving 4.Safety 5.Environment friendly 6.Value Maintain

Msp quadra 500+ tmt barshave high fatigue resistance to dynamic / seismic loads due its higher ductility .This makes msp quadra 500+ tmt bars most suitable for use in earthquake prone areas. Diameters 8mm, 10mm, 12mm, 16mm, 20mm, 25mm, 32mm Available in a fixed length of 12 mts.
Heating and hardening methods Steel has a critical temperature at which it becomes ductile and begins to change its chemical structure. When steel is heated above this temperature, it enters what is known as the austenite stage. From this point on, engineers can create the correct shape and quality of steel that they need. There are many ways to heat treat steel, including but not limited to: Annealing - heating and then slowly cooling the steel to refine it and make it softer Carburizing - using heat and carbon-rich materials to add carbon to the surface Surface Hardening - Carburizing and rapidly cooling the steel so that the center remains soft and the rest hardens Cyanide Hardening - similar to surface hardening, but uses molten cyanide salts instead of carbon to form a hard shell Decarburization - removing carbon from a steel alloy by heat or oxidation Nitriding - adding nitrogen to the surface of steel using heat and a nitrogen-rich liquid or gas Stretching or Tempering - reheating steel that has been cooled to a specific temperature to remove hardness
AR400 Steel AR400 is designed for wear and abrasion applications.Typical hardness of AR400 ranges from 360-444 BHN, which is slightly lower than AR450.Like other wear-resistant steels, it does not have a defined chemical composition, but rather a grade based on hardness. Benefits of AR400 Steel When determining which wear-resistant steel is best for your application, it is important to note that each grade responds differently to many manufacturing processes.AR400 steel plate is ideal for applications that require wear resistance but must be formable and weldable. Because of these properties, it can be used in a variety of different applications. It is particularly suitable for applications where impact or sliding wear may be present.
