Shanghai World Financial Center, the construction material is S235 angle steel. Currently katalor has a large number of S235 angle steel stock.

S235 angle steel contains a variety of chemical composition, including carbon content of 0.22%, manganese content of up to 1.6%, these chemical components to ensure the angle tensile strength, minimum elongation and minimum yield strength and other mechanical properties. S235 production process can be divided into two kinds of hot-rolled and cold-formed, hot rolled for large size angle, cold bending is generally relatively small. Standard process is the use of steel billet through a dedicated multi-channel rolling mill rolling gradually rolled into ∨ shape, katalor production of the product quality assurance, in the corner of the transitional arc inside, mechanical and reliable
