Our Main Product

Steel plate

1.Abrasion resistant steel plate

Abrasion Resistant Steel Plate, AR Steel Plate for short, is one of the most versatile wear plate in the world. It is special used for working conditions under large area abrasion. It is made by reinforcing alloy wear layer with suitable thickness, high hardness,good wear property on the surface of the general low-carbon steel or low-alloy steel which has good toughness and plastic property through hardfacing method. Wear resistant (abrasion resistant) steel is widely used in the bad working conditions,demanded of high strength,high-wear-resisting performance in engineering, mining, construction,agriculture,port and metallurgical machinery products.

2.Alloy steel plate

Alloy steel is steelthat is alloyed with a variety of elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties. Alloy steels are broken down into two groups: low-alloy steels and high-alloy steels.Our alloy steel plate include Q195,Q345B,Q345C,Q235C, 40Mn2, etc.

Steel pipe

Steel pipe are classified into 4 types: seamless steel pipe, square steel pipe, welded steel pipe, galvanized steel pipe. Within these categories, customers can select different shapes and over 200 specifications.All the products are manufactured strictly with GB/T6728-2002 and ASTAMA500 and etc. The overall production environment guarantee the total output of products reaches at 1000 thousand tons every year.

Steel bar

Steel bar is widely used in hardware, chemistry, foodstuff, medicine apparatus, making industry, computer or notebook components, etc. Common steel bar grade include Chinese Standard: 20#, 25#, 35#, 45#, 50#, 60#;Japan Standard: S20C, S25C, S35C, S45C, S55C, S60C;US Standard: AISI1020, AISI1040, AISI1045, AISI1050;Europe Standard: CK15, C. 22, C45, CK45, C60, CK60; C45E.

(2) Successful Cases

Elkem is a company that produces solar grade silicon, silicon, alloys for the foundry industry, carbon and microsilica. Elkem is owned by China National Bluestar Group Co. Ltd. (Bluestar), which bought the company from Orkla Group for 2 billion USD in 2011. The deal excluded 85 percent of the sister company Elkem Energi AS.

Elkem has four business areas; Silicon Materials, Silicones (BSI), Foundry Products and Carbon.Elkem Carbon is the world’s largest producer of electrically calcined anthracite and electrode paste, which are necessary in the manufacturing process for steel, aluminium , silicon and other metals. There are production plants at Kristiansand (Norway), Shizuishan City (China), Witbank (South Africa) and Vitória (Brazil).

We supplied to Elkem and do the laser cutting,rolling, bending for them.
