Duplex stainless steel (DSS for short) refers to stainless steel with ferrite and austenite accounting for about 50% respectively, and the content of less phase generally needs to reach 30% at least. In the case of low C content, Cr content is 18% ~ 28%, Ni content is 3% ~ 10%. Some steels also contain Mo, Cu, Nb, Ti, N and other alloy elements. This kind of steel has the characteristics of austenite and ferritic stainless steel. Compared with ferrite, it has higher plasticity and toughness, no room temperature brittleness, significantly improved intergranular corrosion resistance and welding performance, and maintained 475 brittleness, high thermal conductivity and Superplasticity of ferritic stainless steel. Compared with austenitic stainless steel, it has higher strength, intergranular corrosion resistance and chloride stress corrosion resistance. Duplex stainless steel has excellent pitting corrosion resistance and is also a nickel saving stainless steel.

I-Beam Steel I-Beams, also known as H-Beam, are one of the most common steel profile used in construction and civil engineering. It provide support for buildings and load-bearing walls. The I-shaped section optimises strength weight ratio & surface usability to provide a highly efficient product. It is right-angle formed & so has high bending resistance, construction application simplicity. It save cost, is light weight and thus is used widely in various industries.
T-Beam: A T-Beam is a load-bearing structure with a t-shaped cross section. The top of the t-shaped cross section serves as a flange or compression member in resisting compressive stresses. The web of the beam below the compression flange serves to resist shear stress and to provide greater separation for the coupled forces of bending. Other uses for one way to make a T-beam to be more efficient structurally is to use an inverted T-beam with a floor slab or bridge deck joining the tops of the beams. Done properly, the slab acts as the compression flange.
Angle Bar Angle steel bars are perpendicular elongated steel bars connected together as a wave-like product. There are equal angles and unequal angles. Angle steel bar is a simple sectioned carbon structural steel mostly used in metal products fabrication and construction of workshop. In application, it must has weldability, plasticity deformation performance and high mechanical strength. The raw material to produce angle steel is low-carbon billet. Finished product of angle steel is hot roll formed.
Square Tubes: Structural Tubes, also known as hollow sections, are used as a structural element in buildings, bridges and other structures, and in a wide variety of manufactured products. It’s produced in round, square and rectangular shapes in a broad range of sizes and gauges. Square Tube, similar to round tube, has efficient shape for multiple-axis loading as it has uniform geometry along two or more cross-sectional axes, and thus uniform strength characteristics. This makes it good choice for columns. It also has excellent resistance to torsion.
Rebar Bars: The rebar, also known as deformed bar, is a steel bar or mesh of steel wires used as a tension device in reinforced concrete and reinforced structures to strengthen and hold the concrete in tension. Rebar’s surface is often patterned to form a better bond with the concrete.
