PRODUCT CENTER
Classification of steel: According to the chemical composition, steel is divided into carbon steel and alloy steel; according to the use of steel, it can be divided into structural steel, tool steel and special performance steel.
Material: Carbon steel: 10#, 20#, 35#, 45#, S45C, 55#, Q235B, Q235C, Q345D, CF53, A105 Gold steel: 16Mn(0345B).20Cr40Cr15CrMo.20CrMo.28CrMo,30CrMo.35CrMo42CrMo.4130.414020 CrMnT.40MnMoV20Mn237Mn5ZF6.16MnCr5,20MnCr5.36Mn2V38Mn2V 20Mn2.65Mn.15Mo3Others: Special materials can be customized
Curtain Wall Square And Rectangular Tube
Curtain wall square and rectangular tubes are also known as square and rectangular cold-formed hollow sections, referred to as square tubes and rectangular tubes, codenamed F and J respectively.
Curtain wall T-shaped steel is a T-shaped steel supporting device for building curtain walls, including at least one column and at least one crossbeam fixedly combined together. The column and the crossbeam are both T-shaped steel. The column includes wing plates and webs.
Curtain Wall Right Angle Square Tube
The most outstanding feature of refined steel profiles is that they have the same surface flatness and straightness as aluminum profiles, and the outer R-angle is 90 degrees right angle. In glass curtain walls, under the same span conditions, the advantage of refined steel is that it can achieve a smaller volume and more flexible cross-section than aluminum profiles, achieving a more transparent lighting effect. Ordinary steel materials are mostly galvanized square tubes or hot-rolled rectangular steel tubes. They have a large R angle, rough appearance, insufficient straightness, and large bending deformation, so they cannot be used in high-quality glass curtain wall projects.
