SS400 SM400A Carbon Steel Beam

SS400 according to material grade and name defined in the JIS G 3101 standard, The first S stands for "Steel", the second S stands for "Structure", and 400 for the lower limit tensile strength of 400 MPa. Ordinary structural steel with a tensile strength of 400 Mpa. This steel is the most widely used in JIS standard. SM400A belongs to the ordinary carbon structural steel plate in the hot rolled carbon steel plate, 400 represents the tensile strength of more than 400, SM is the name of the Japanese standard material, A represents the level, indicating that there is no impact. There's also SM400B, which stands for ambient shock. SM400C stands for normal temperature impact, SM400D stands for -20 degree impact, SM400E stands for -40 degree impact,

What is a Beam and What is Its Purpose?

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.
