Steel purlins provide much-needed support to the roof by holding the overall weight of the roof deck. When you take a look at a shop that offers building materials in the Philippines, you will come across numerous types of purlins. Out of them, steel purlins are the most popular. You will be installing them over the top of roof rafters. Along with the purlins, you will need to install a vapor barrier or a felt underlayment as well. You can buy these from your purlins supplier as well.
The dimensions of steel purlins measure 2 x 4 feet in size. You will have to go through a process that is quite similar to metal roofing installation to get them installed. Upon the installation of steel purlins, you can provide much-needed support for the roof. On the other hand, you can use them as a nailing surface for the drip edge and end panels. This is why you need to be mindful about the quality of purlins as you shop for cheap price building materials.
After you get the purlins from a shop that offers quality building materials, you can go through the installation process on your own. Here are the main steps that you will need to follow for the installation.
You will need to take measurements before you proceed with the installation of steel purlins. This is where you should take a tape and measure the end to end length of rafters on your roof. This will help you to get a better understanding about the number of purlins that you need for the installation. Make sure that you know the count before you buy building material for the contractor or you. This will help you to refrain from paying back to back visits to the hardware store. On the other hand, you can save a considerable amount of money by purchasing purlins in bulk.
Now you need to take a piece of chalk and snap that horizontally across your roof, at a distance of 2 feet down from its top. Then you can proceed with laying the very first purling. Make sure that you keep it at the ridge of your roof, while keeping an eye on the chalk line that you can see at the start of any corner. After the placement, you may fasten the placed purlin with the help of 16d common nails at every vertical rafter. You will need to place two different nails to the rafter at an equal distance from each other.
As the next step, you will need to keep the second purlin in horizontal direction, just next to the first one and install it in a similar manner. You can follow the same steps until you complete the first row. Then you can cut the final purlin into different sizes along with tin snips if required.
Now you come to the last step, where you should move two feet down your roof and draw another horizontal line with chalk. After that, you can proceed with the installation of the second line of purlins. Likewise, you may continue, until you cover up the entire roof with purlins.
These are the steps to proceed with the installation of steel purlins at your home. Upon the completion of the job, you will be able to carefully inspect the area, so that you can make sure that no nails would stick up. Likewise, you can also make sure that all the purlins would properly secure into the rafters.

Sand is among the most prominent materials used for construction. It is capable of offering bulk, strength, as well as stability for the materials such as cement, asphalt, mortar, and concrete. However, there are different types of sand, which will need to be used for different purposes. Let’s take a look at the different types of sand and how they are being used for different construction purposes.
- Masonry sand
Masonry sand is being used at the time of making mortar or concrete. This is finely-grained sand. It is possible to use masonry sand when laying blocks, stones, or bricks. On the other hand, it is quite useful during patio constructions as well. You can easily create an aesthetic appeal with the assistance of masonry sand.
- Utility sand
Utility sand is made by crushing industrial quartz. Hence, it is possible to create uniform grain shapes. You can discover a coarse texture in utility sand. It has a mixture of white, tan, beige, brown, and gray-colored particles. Utility sand is a common material used for making the base material of concrete.
- Fill sand
When you take a look at fill sand, you can discover extremely fine particles of rock. These rocks disintegrated to sand along with time. The rocks are crushed multiple times by machines to make them extremely fine. You can discover a great compaction rating infill sand. However, it is susceptible to shifting and displacement.
- Concrete sand
As the name suggests, concrete sand is being used for making concrete mixtures. This type of sand consists of limestone, gneiss, and granite rock. You will be able to discover angular granules within concrete sand, which works perfectly well with cement. Apart from being used in concrete, you will also be able to use concrete sand in bedding pipes as well.
- Crushed stone sand
Crushed stone sand is the natural successor that you can find in river sand. You will not be able to find any impurities in crushed stone sand. Hence, you will be able to use crushed stone sand when making concrete without having a doubt in mind. It goes through a rigorous crushing process as well. You will often be able to see how construction sites use crushed stone sand as a material for plastering.
- Industrial sand
Industrial sand is another name for silica sand that has a very high purity level. It comes with controlled sizing as well. You can often see how industrial sand is being used during construction and building projects. It is possible to add industrial sand at the time of making roofing shingles, specialty cement, asphalt mixtures, flooring compounds, as well as skid-resistant surfaces.
One of the best things that you will notice in industrial sand is the flexural strength it has. Moreover, it can also provide a great packing density, which will not compromise the chemical properties of the
binding system. You will also be able to use industrial sand to deliver anti-corrosion properties to caulks, sealants, as well as epoxy-based compounds.
- Finely crushed limestone gravel
Limestone gravel is one of the coarse materials used at the time of making solid compact surfaces. Limestone is finely crushed, and it doesn’t offer any assistance with water drainage. Hence, you will be able to use finely crushed limestone gravel to support indoor flooring as well as patios.
Now you know what are the different types of sand used for construction activities. With this understanding, you can figure out what type of sand to be used for the construction project that you are working on.
