Welding Mezzanine Purlins

Among building structures, steel structures have good earthquake resistance and have a high degree of industrial production. The steel structure construction period is short, and it has the advantages of energy saving, environmental protection, and good ductility. Especially for steel structure buildings, its ductility can generate seismic waves. Attenuation effect to reduce earthquake damage to steel structure buildings. Steel purlins are suitable for all aspects of steel structure projects such as roofs and walls. The cross section forms of purlins generally include C-shaped, Z-shaped, U-shaped, several-shaped steel, etc. Their function is to reduce the span of the cabin panel and fix the roof panel.

When it comes to building a sandwich, choosing the right purlin is crucial. Purlins are horizontal beams that support the mezzanine deck. Purlins are available in a variety of materials, including steel, aluminum, and even wood. However, welded sandwich purlins are one of the most popular options because it provides a strong, reliable support structure.

Types of purlins: Before delving into welded sandwich purlins, it's important to understand the different types of purlins available. The most common purlins used for sandwiching are C and Z purlins. C purlins are shaped like C, while Z purlins are shaped like Z.C purlins are usually used for smaller mezzanines, whereas Z purlins are ideal for larger mezzanines.

Welding sandwich purlins: Several factors should be considered when welding sandwich purlins. The most critical factor is the type of steel used. Sandwich purlins are usually made of hot-rolled steel and should have a minimum yield strength of 345 MPa. In some cases, structural steel, such as S355, can be used for larger interlayers.

Another important factor to consider is the welding process. Different welding processes can be used, including MIG (metal inert gas) and TIG (tungsten electrode inert gas) welding. MIG welding is the preferred choice for welding sandwich purlins because it is faster and can produce a strong weld. TIG, on the other hand, is slower but produces a higher quality weld.

Sandwich purlins should be precisely cut and prepared before welding. This ensures that all purlins are the right size and length, and that they are straight without any burrs or chips that could weaken the weld joint.
