Iron and carbon are the most abundant materials in steel. Pure iron isn't particularly strong or hard on its own, so adding carbon helps give steel tremendous strength.

The crude iron used to produce steel has a relatively high carbon content. Its carbon content can be as high as 2.1%, which is the maximum amount of carbon a material can contain and still be considered steel.

As an important material, stainless steel has shown outstanding advantages in various fields. Its corrosion resistance, high strength, high temperature resistance, hygiene, aesthetics, recyclability and wear resistance make it the material of choice in many industries. This article will introduce the advantages of stainless steel in detail from these seven aspects and explain the charm of stainless steel for you.

2. All stainless steel sheets will be packed in sturdy wooden packaging.

3. Each carton is equipped with good support and reinforcement.

4. Take photos of container loading and seal the container.

5. Fast transportation. And let customers know every step of the way.

PPGI stands for pre-painted galvanized iron sheets/coils which are made by coating galvanized steel sheets with several layers of paint & coatings under controlled conditions in a continuous coil coating line (CCL). These products have high durability as well as chemical resistance properties making them ideal for many industrial applications like roofing sheets/Walling/Cladding materials for the construction industry etc.

Galvanized coil, the thin steel plate is immersed in a molten zinc bath, so that a layer of zinc is adhered to the surface of the thin steel plate. It is mainly produced by the continuous galvanizing process, that is, the rolled steel plate is continuously immersed in a plating bath containing molten zinc to make galvanized steel plate; alloyed galvanized steel plate. This kind of steel plate is also made by the hot dip method, but it is heated to about 500°C immediately after coming out of the tank to form an alloy film of zinc and iron. This kind of galvanized coil has good paint adhesion and weldability.

Rongrui Metal Products (Shandong) Co., Ltd. was established in 2014 and is a large-scale steel enterprise group. The company's headquarters is located in Jinan City, Shandong Province, with modern production bases and advanced production equipment.

Test items:

Common detection-chemical composition: analysis of C, S, P, Mn, Si, Cr, Ni element content; common analysis-spectral analysis: photoelectric colorimetric analysis; polarographic analysis;

Stainless steel plate is used more in our life, and its processing industry is also more diverse, mainly including cold rolling, calcined and hot rolling, etc. Today, we will introduce the calcined stainless steel plate process:

Reinforcement refers to steel for reinforced concrete and prestressed reinforced concrete, which is circular in cross-section and sometimes square with rounded corners. Including plain round bars, ribbed bars, twisted bars. There are many types of steel bars, usually classified by chemical composition, production process, rolled shape, supply form, diameter, and use in structures. The steel bar for reinforced concrete refers to the straight or coiled steel used for reinforced concrete reinforcement, and its shape is divided into two types: smooth round steel bar and deformed steel bar. Steel bars mainly bear tensile stress in concrete. Due to the effect of the ribs, the deformed steel bar has a greater bonding capacity with the concrete, so it can better withstand the action of external forces
