A c purlin sometimes referred to as a cee purlin, is a metal channel that is used in construction projects, typically for building metal buildings, carports, and metal roofs. These items traditionally go longitudinally along the roof and are used to support, sturdy, and strengthen the roof sheeting. They can also be used around windows.
C purlins come both punched and unpunched. They are available with sleeved connections and buttoned connections. Typical finishes for this product include both red oxide and galvanized, with red being said to be the more popular finish.
How Purlins are Made
Purlins start out as a slab of metal, in particular steel. The steel slab is rolled between heavy rollers until it is a flat metal sheet. That sheet is then formed into the desired purlin shape, such as a C shaped purlin or a Z shaped purlin. These two types of purlins get their name from the letter they resemble.
Common lengths that c purlins are manufactured in include twenty feet, twenty-five feet, thirty feet, and forty feet. If a project calls for longer pieces, the smaller pieces can be joined together or specialized sizes can be ordered from metal manufacturers. Gauges available for c purlins include twelve gauge, fourteen gauge, and sixteen gauge.
A Guide to Spacing C Purlins
C purlin span guide refers to the spacing of the bars. Some projects that need a lot of strength and reinforcement will require that the c purlins be placed closer together. Local building codes may also have requirements that will need to be followed. If the user has questions about spacing, they can always consult an engineer or building professional to make sure that the project they are working on will be as sturdy and safe as it should be.
A Cost Estimation for C Purlins
When it comes to c purlins price, the price is based on the thickness and the length that the project calls for. Shorter and thinner bars will cost less than the longer and thicker versions. The reason behind this is that it takes more metal and labor to make the larger bars than it does to make the shorter and thinner bars. The thicker bars are stronger, the longer bars cover more area, so the user is paying more but they are also getting more. When estimating the costs of the project, also keep in mind delivery fees. If the user is able to pick the metal up in person this can save on delivery costs.
In conclusion, purlins are used in construction and projects to strengthen and secure metal materials, such as metal roofs and metal building pieces. They come in an assortment of lengths and finishes, and the price will be based on thickness, length, and other fees such as those for delivery. Before starting on a building project, always research local building codes and regulations, and check with an engineer to make sure the project is as safe as it can be.
