Profile
HSS, standing for hollow structural section, is a hollow structural profile also known as square tube. Square tube is a long steel with a hollow section and no seams around it. Moreover, square tubes are made of hollow sections and are generally used as pipes for conveying fluids.
HSS, standing for hollow structural section, is a hollow structural profile also known as rectangular tube. It is a long steel with a hollow section and no seams around it. Unlike square tube with equal side length, rectangular steel HSS tube have different side lengths.
CHS Circular Steel Hollow Section
As with square HSS, round steel HSS is ideal for creating uniform geometries. Round tubing is well-suited to constructing columns and features a high resistance to torsion.
Z-shaped sheet piles are called Zs because the single piles are shaped roughly like a horizontally stretched Z. The interlocks are located as far away from the neutral axis as possible to ensure good shear transmission and increase the strength-to-weight ratio. Z piles are the most common type of sheet pile in North America and can be used in a wide variety of applications.
