Corrugated galvanized iron or steel is a building material composed of sheets of hot-dip galvanized mild steel, cold-rolled to produce a linear corrugated pattern in them. The corrugations increase the bending strength of the sheet in the direction perpendicular to the corrugations, but not parallel to them. Normally each sheet is manufactured longer in its strong direction.

H beam is an economical and efficient section with more optimized section area distribution and more reasonable strength-weight ratio. H beam has the advantages of strong bending resistance, simple construction, cost saving and light structural weight in all directions, and has been widely used.

U Channel is kind of carbon structural steel, for its high strength and good weldbility, it can be used in construction and automobile manufacture.

T-beam is a type of steel cast into a T-shaped shape, which has the advantages of strong bending resistance, simple construction, cost saving, and light structural weight

Angle steel is a carbon structural steel for construction, which is a section steel with a simple section, mainly used for metal components and the frame of a workshop. In use, it is required to have good weldability, plastic deformation performance and certain mechanical strength.

Box columns are generally composite columns, which are assembled from steel plates. The circular steel pipe column generally bears the parts with less axial force or eccentric force, while the box-shaped steel pipe column can have a larger cross-section in one direction, which determines that it can be used in places with greater eccentric force.

The structural channel, also known as a C-channel or Parallel Flange Channel (PFC), is a type of (usually structural steel) beam, used primarily in building construction and civil engineering.

Z-beam is a common cold-formed thin-walled steel, processed from hot-rolled (painted) and galvanized materials, with good bending resistance and convenient installation

I beam is I-shaped, and the section of H-shaped steel is the same as the English letter H, and the strength to weight ratio of H-shaped steel is more suitable for economical steel sections.
