9/26/2023 0 Comments Steel roof trusses residentialThe method of learning how to build the roof trusses might be a bit more complicated compared to other methods since you will need to take some extra steps of cutting the gussets that are used for giving the needed extra support and strength to the truss. If you want to build a roof truss with the use of other materials aside from wood, like steel, aluminum or tin, you will need to cut the material based also on the roof size and design specifications, just like with wood trusses. Depending on the wood’s thickness, you might also want to use thicker screws. The plates and the wood will join together in the shape of a triangle and will then be fastened together using galvanized steel screws, which aren’t shorter than 1 ½ inches in their length. It is a kind of steel that has a zinc coating and can prevent the occurrence of any corrosion. It is crucial that you use connector plates made from galvanized steel. Most of the time, the sizes of the wood used range from 2×6 and 2×8 even though its thickness can be based on the weight that it will support and the overall size of the roof. It must also adhere to all the local building standards and codes. The wood needs to be cut based on the size of the roof and specifications in the design. These will include wood, a hammer, a saw, roof truss plates made from galvanized steel and galvanized screws of 1 ½ inches. The second step in building a roof truss is to prepare the materials needed. The very first step for building roof trusses is to prepare a design layout that can be sketched by a professional architect or can also be done by using a software that is specifically meant to design a roof truss. It allows a lot of open space unobstructed by the poles for support. Typically, the upper chords have different lengths in this particular type of truss that make the apex off-center. These are attached to the horizontal beam, thus making up the triangle’s base. Its conventional triangular truss design is that the two sides are sloping up to the apex above, with the struts known as the upper chords leading down from it. The water can run off easily from this kind of roofs and a ridge cap is not required. Several beams make up the arch, while the roof outside is made up of metal sheets or other materials. Usually large and arched, the bowstring trusses give support to the building’s weight, such as the aircraft hangars and the warehouses that require a lot of open space inside. There is also an extra room for the large windows that can make it look brighter inside the house. ![]() ![]() The gambrel roof truss in homes lets you include an upper floor below the roof. Since it has steep sides, there is sufficient room for a living space below the roof or can be used as a storage space in the attic. These two chords meet at the truss’s apex. It has two upper chords, with one longer than the other. ![]() The gambrel roof truss resembles the appearance of a barn roof. While among the most common types, this truss is considered as less efficient because the stress on the webs of the flat trusses is greater compared to other types. This can be cantilevered at one or both ends.Ī flat truss is not necessarily flat, as it slightly slopes to prevent the pooling of water on the roof and prevents the damaging or collapsing of the entire structure. The flat truss can be designed as bottom or top chord bearing or for multiple and simple spans. Types of Roof TrussesĪside from the common wood roof trusses, there are still other types that are built using different materials to effectively support and distribute the load to the walls. Today, there are many home builders who choose to order the prefabricated roof trusses from manufacturers and have these delivered to the building site because building trusses can be labor intensive and the prefabricated ones will help them save time, money, and materials. Lastly, if you would like to free yourself from the expenses and headache caused by building a strong and durable roof, it is highly recommended to build a truss. The angles needed can be very hard to measure and frame properly. ![]() When a roof truss is not constructed, it can be difficult to properly frame the roof of a house or building.
