Apex Purlins and Girts are roll-formed from Hi-Tensile Galvanised steel. They are primarily used to provide lightweight, economical, efficient roofing and cladding support systems for framed structures. Apex Purlins and Girts are available in a range of different sizes and configurations.

C-sections have equal flanges and may be used in single spans and unlapped continuous spans in multi-bay buildings. Their freestanding stable shape allows easy handling and storage and is easily adapted for use in small and medium sized buildings as structural framework.

Z-sections feature one broad and one narrow flange allowing the two sections to fit together snugly, making them suitable for lapping. Z sections of the same depth and different thickness’ can be lapped in any combination. Purlins and Girts that are lapped form a structurally continuous line along the length of the building, a factor that contributes significantly to the reduction in building costs. Apex offers the added flexibility of downturn lips and adjustable top flanges for all sizes. Downturn lip purlins are ideal in applications where environmental conditions or build up of substances like dust or grain are a consideration. For special or large projects, Apex is able to customise sections outside the standard range to suit your individual requirements.


Purlins constitute the most important aspect when it comes to any kind of structural support system in a building. It's a horizontal beam used for structural support, most commonly applied beneath roofs. They attain support from the rafters and building walls. Purlin manufacturers most commonly produce three types of purlins, namely, Z and C purlins and rectangular hollow section purlin.


Purlin Roofing Systems

Designed to reduce the distance the rafters have to span, metal purlins support the loads from the roof deck and help to prevent the roof from sagging. Metal for Roofing offers two types of galvanized purlins:


C Purlin - Cee or C purlins are shaped like a squared-off letter C. They are often used for structural support in walls and as floor joists in addition to roofs.


Z Purlin - The zed or Z purlin is shaped like a letter Z. Its shape allows the purlin to overlap with others at the joints. This gives zed purlins the potential to be much stronger than C purlins. Z Purlins are mainly used in walls or for large roofing projects.


Advantages of C Purlins

Ability to span length

Purlin construction is easier to assemble and handle

Assured dimensions and straightness

High durability, versatility and uniform quality

Low transportation cost due to decreased weight

For the roofing of your metal building, we offer C-shaped dip-hot galvanized purlins with strong inertia and resistance.

 

The purlins are fixed on the crossbars in order to strengthen the roof. At the downslope, our galvanized gutters replace the eave purlins. In areas with high snow loads, we usually add one (or several) purlins to the roof to balance the structure load.

Our standards ranges therefore take into account the number of purlins required, according to the construction area of the building.

Red oxide receiver channel is available in 20' and 25' lengths in a 14 gauge metal thickness. See the graph below for C channel sizes that are in stock for immediate pick up or delivery.


Channel steel is a long strip of steel with a groove-shaped section. It is a carbon structural steel for construction and machinery. It is a section steel with a complex section. Its section shape is a groove-shaped steel.


C Purlins are available in different sizes and material strength (Eg, 240 Mpa and 350 Mpa) to match the design computations of your building. 


Purlins are perpendicular structural support member in slope of roof and cladding placed on principle rafter. These roof purlins are extensively used in large sized infrastructure project, factory, Godowns. 


C purlins are made from GI / CR / HR / GP / Quality Steel and is roll formed to required length with factory made punching to your specifications and requirement.


Channels are secondary steel framing members that serve as a receiver channel at the end of steel purlins. They can also be used for a number of other applications either alone or welded back-to-back. Receiving channel is also used to receive purlins or girts at the ends of the building structure.

They are 1/8 inch taller than the Cee or Zed profile, so the end of the profile will slip in perpendicular to the channel. The top and bottom of the profile are bolted to the flanges of the receiving channel. Receiving channel is typically used in carports and low strain applications.


Steel purlins are necessary for pre engineered steel industrial buildings,  and some residential building as well, and various kinds of c/z purlin roll forming machines have been developed to produce C/Z/U steel purlins, Sigma/M purlins sometimes are also available.

There are many components that contribute to the stability of a metal building. When it comes to roofing, metal purlins are a critical element needed to give the structure proper support.

Though we do not do installations ourselves, Western States Metal Roofing has been providing contractors with the materials required for a successful installation for over two decades.


Not all metal purlins are the same as they come in different types and sizes. Therefore, it is important for you to know the differences and use the right purlin for your project.


This article goes over the different types of metal purlins so you will know everything you need to before purchasing your materials.

What Is A Metal Purlin?

A metal purlin is a lightweight, horizontal beam or bar that is used for structural support in roofing. In addition to providing support, metal purlins also increase a building’s resistance to heavy winds. Purlins are a key component to the secondary frame of commercial, residential and industrial metal buildings.

When used with roofing, metal purlins support the weight of the roof decking. This makes purlins a critical element to the structure of roofing.

There are different types of metal purlins that are characterized by their shapes. We go over the most common types of metal purlins below.

Advantages Of C Purlins

Ability to span length

No side drilling/cutting required

Assured straightness

Durable

What Is A Z Purlin?

Z purlins, also called Zee Purlins, are horizontal beams that form the roof and wall joists of a building shell structure. The name comes from resembling the letter Z. The shape of the purlins helps in overlapping the joint which makes it stronger and studier than C purlins. They are often used on large-scale structures because of their strength.


The main advantage with a zee purlin vs a cee purlin is that the shape of the z purlin allows for the purlins to overlap.

Metal Purlin Finishes: Red Oxide vs. Galvanized Metal Purlins

Metal purlins come in two finishes: red oxide, also referred to as “red iron” or galvanized. These finishes to protect the bare steel that would rust in just a couple of days if left untreated and exposed to the elements.

The red oxide consists of a sprayed paint primer in a red finish.

Galvanized metal is a finish that goes through a process which applies a zinc-alloy plating. This makes the material corrosion resistant so it’s able to resist damage from even the harshest environments, such as a chemical plant or in areas near salt water where rusting is inevitable for unfinished steel.

Though it’s appropriate for salt water environments, galvanized steel is not resistant to oxidizing and can develop an unattractive white rust when exposed to moisture. Red oxide can also develop a surface rust after being exposed to moisture, but the red rust color is disguised by its painted red coloring.

There is no difference in the structural strength between the two finishes.
