4 Major Differences About C Purlin & Z Purlin that You Might Not Know

There are many type of purlins in the industry, and are categorised depending on their material and the form of their shape. In the construction of metal buildings, steel purlins are most commonly used for structural support. 

Different steel purlins in different forms or shapes are used for different uses as roofing, structural wall or floor support. Besides their obvious structural appearances, C purlin and Z purlin are distinct in mechanical properties and their use as roofing and wall support.

This article seeks to outline the four main differences about C purlin and Z purlin that you might not know.

#1 Structural Differences

C purlins are formed in the shape of a ‘C’, and all the angles of a C purlin are 90º, while Z purlins are formed in the shape of a ‘Z’. Not all angles of a Z purlin are at 90º.

When deciding which purlin to use, it is necessary to consider the angle of the purlin and where it will be fixed as part of your construction project. Take advantage of the purlin’s bending performance.

#2 Mechanical Properties

C purlins have similar extensions on their ends, meaning that they can be used in single spans. Z purlins on the other hand, have a relatively high flexibility and are lightweight enough, making them easily adapted for use in a variety of different sizes 

Thung Hing Group offers a selection of TH C purlins and Z purlins in various thicknesses and length to suit your specific needs and requirements

#3 Use in Roofs

C purlins are easy to install and calculate, thus it is recommended for use in roofs of steel framed structures with single spans and for supporting walls. In roof with concealed fixing or clip lock roof panels on the other hand, Z purlins can work better than C purlins.

#4 Use for Walls

When used as wall support, C purlins are ideal for structural support in walls and also as floor joists. They can also be used to form braces, ties or column in sheds. 

In comparison, Z purlins can be overlapped continuously therefore it is recommended for use to bridge multiple span, on metal buildings with continuous spans.

C 型钢檩条与 Z 型钢檩条,您所不知的四大区别

工业用途的檩条有多种类型,并依据各自的材料及形状而分类。在金属建筑方面,钢檩条最常用于结构支撑。

不同形式或形状的钢檩条可用于支撑屋顶,结构墙或地板。除了它们外形结构区别之外,C 型钢檩条和Z 型钢檩条都具有不同的机械功能和屋顶及结构墙支撑用途。

本文概述四项关于C 型钢檩条和Z 型钢檩条的主要区别。

#1 结构区别

顾名思义,C 型钢檩条外形呈 ‘C’ 字型,且所有的角度均为 90°,而 Z 型钢檩条则呈 ‘Z’ 字型。Z 型钢檩条的角度并非全都是 90°。

再决定选用哪种钢檩条时,您必须考虑钢檩条的角度及它在建筑项目中的用途,并充分利用该钢檩条的弯曲性能。

#2 机械性能

C 型钢檩条末端具有相同的扩展,它们可充分在单个跨度中使用。另边霜,Z 型钢檩条轻巧而具有较高的柔韧性,因此它适用于各种尺寸的跨度。

东兴集团提供各类型不同厚度和长度的 C 型钢檩条Z 型钢檩条以迎合您的建筑需求。

#3 屋顶建筑用途

C 型钢檩条 易于安装及计算,因此建议用于单跨度的钢框架结构屋顶和支撑墙。另外,若用于隐藏式固定或夹锁的金属屋顶板,Z 型钢檩条更为适合。

#4 支撑墙用途

当用于支撑墙时,C 型钢檩条是墙体结构支撑及地板拖梁的最佳选择。他们也适用于棚子的支撑,扎带或圆柱。

相较之下,Z 型钢檩条可连续重叠建筑,因此建议用于具有并联跨度的金属建筑物中,桥接多个跨度。

C 型钢檩条与 Z 型钢檩条, 哪个更适合您的建筑?

以上内容可提供 C 型钢檩条与 Z 型钢檩条的基本知识,以协助您在建筑所需时做出明智的抉择。
