Making my own invention at home

A truss acts as a structure's main framework, and it is comprised of rafters, posts, bridges, or struts. Trusses may be designed using various materials, and the architectural shape is determined by the project's requirements. Most structures today have steel trusses due to the durability, strength, and reliability of steel. Other than these beneficial features of steel, the steel fabrication process isn't difficult—the material is versatile and flexible.

Reasons steel trusses are popular

In any construction project, builders choose either steel or wooden trusses. Although wooden trusses are often used in residential applications, most modern buildings today opt for steel trusses. In addition to being susceptible to shrinkage once moisture content in the timber evaporates, wooden trusses aren't as durable as steel. They can warp, rot, or be infested by termites. With steel, you will not face any of these issues, and that's why these trusses are suitable for numerous applications such as outdoor markets, commercial buildings, schools, auditoriums, institutions, sports stadiums, and other buildings. Steel doesn't burn and it's recyclable, meaning its use doesn't have adverse environmental effects.

Types of steel trusses

The procedure used to fabricate steel trusses is complex. Special techniques and tools are needed, including the skill and experience of a steel fabrication expert. These structures are created in three primary stages—cutting, forming, and assembling. Forms of trusses your fabricator can create include the following.

Pratt – Also known as the 'N' design, this form of truss involves welding numerous vertical chords to one diagonal chord that's attached to the topmost section of a vertical cord, and then to the bottom part, creating an N. Often, you will see this steel truss design in bridges.

Fink – If you have a small building and prefer installing steel stresses, the Fink design will be more suitable. The cords of the design are prearranged in short distances and easier patterns.

North Light – This design's name was derived from the truss placement setup. The structure comes in a triangular shape that has a short and long slope, and the short side faces the north direction. These trusses are commonly used in workshops.

Scissor – If you are searching for a suitable design for larger buildings like a church, museum, or stadiums, choose the scissor design. It entails two sloping sides, as well as a huge, empty ceiling centre. This design is only suitable for large spaces.

If you aren't sure about the design you should choose, your steel fabricator will advise you accordingly and ensure that you get quality steel trusses that meet your project's needs.
