Galvanized Z profile steel bar is the main structure in the bulding , our products are in a good market in the world !
Cold-formed steel has been widely adopted as the main load-bearing component of the portal frame.
However, they use a combination of public-shaped cross section in the door frame of the beam components, studies have shown that ,for small and medium span in the door frame,
if we adopt a single limb Z steel used for beam-column elements, the construction of the node will be more concise, while it will be more convenient to components transportation, installation. Z-beam flange width, nodes on the beam diameter bolts connecting nodes have little effect on bearing capacity and stiffness,
while the material yield strength of the connected nodes bearing capacity and stiffness is relatively large.
