Steel purlins are secondary load-bearing components in the roof structure system, which transfer roof loads to the steel frame. C/Z type steel purlins are both important components for steel structure buildings.
Steel purlins are secondary load-bearing components in the roof structure system, which transfer roof loads to the steel frame. The function of the C/Z type steel purlins is to reduce the span of the roof panel and fix it.
C/Z type steel purlins are both important components for steel structure buildings, but differences such as shape, strength, and applicability between the two purlins are obvious，so in practical applications，appropriate type of purlin should be selected based on specific engineering requirements.
C/Z type steel purlins have their own applicable ranges each other. Z-type purlins have higher strength and stability，which are commonly used in the complex engineering projects. In terms of strength, Z-type purlins have stronger bending and torsion resistance, making them more commonly used in large-span or heavy-duty structures. For example, in industrial plants and large warehouses, Z-type purlins are often selected to support roofs and other facilities. C-type purlins are more suitable for short spans and light loads, and are commonly used in small buildings or lightweight roof trusses. So C-type purlins are widely used in some relatively simple buildings, such as the simple warehouses.
Different cross-sectional heights and thicknesses of the C/Z type steel purlins are suitable for different load-bearing and design requirements.
C/Z-type purlin section diagram is as follow:
The specification ″C250x80x30x3″ means section height h=250mm, section width B=80mm, seam width a=30mm, thickness t=3mm.
The specification ″Z160x61x20x3″ means section height h=160mm, section width b=61mm, seam width a=20mm, thickness t=3mm.
