Products Description
Chemical Composition
Q235 and Q345 are the two most popular steel in China. Both of them are low alloy steel and widely used in construction, railway,
shipbuilding, and other industries.The chemical composition of Q235 is as follows: C<0.28%,Si≤1%,Mn≤1.65%,P≤0.045%, and
S<0.045%.The chemical composition of Q345 is as follows:
C≤0.30%,Si≤1%,Mn≤1.65%,and P≤0.045%.The main differencebetween these two kinds of steel is that the first one contains lesssilicon, manganese, and phosphorus content than the second one.
A beam is a structural element that supports a building or structure. It can be either primary support or secondary support and is generally used to bear a load from some other member, such as a foundation or the outer walls.
Beams are classified by their shapes (I-beams, L-beams, box beams) and sizes (2×4, 2×6). They're also classified by their material and how they're attached to the structure of the building. Beams are generally made from wood, steel or concrete. In addition to these materials, some beams can be made with bamboo or balsa wood as well.
Beams are often used when constructing buildings because they allow for easy installation of wiring and piping without having to worry about overworking any one part of the building too much.
