Z-Purlin, also known as Z-arms, are the horizontal beams that form the roof and wall connections of a steel structure. The name comes from the shape that resembles the letter Z. The shape of the Z arm helps to overlap the joints, making it more durable than the C arm.
Advantages of Z-Purlin
- The C-channels are used to shape structural steel walls with floor joiners. While Z-purlin is used to shape the roof and wall connecting rods of steel structures. Z purlin has an angle of fewer than 90 degrees. Therefore, Z purlin is more flexible than C-channel and can be used for a variety of purposes.
- Z purlin can be stacked, while C-channel cannot. Therefore, in steel structure works with longer span design, it is better to use Z purlin.
If the roof slope is small, the difference between the bending moment of purlin Z is larger than that of purlin C. But if the slope of the roof is increased, the bending moment of purlin Z will also increase symmetrically in the straight direction. stand. Therefore, Z purlins are more suitable for roofs with steep slopes.
- The Z purlin is usually located between the roofing sheets for support while the C purlin is used to support the beams needed for the floor.
- Another point is that the Z purlin can be stacked, so its bearing capacity is quite large. Very suitable for use on projects with roofs requiring large bearing capacity.
