What Is TGI in Construction: Everything You Need to Know

In the world of construction, various building materials and techniques are used to create safe and sturdy structures. One such material that is commonly used is TGI, which stands for Truss Joist Girder. TGI is a type of engineered wood product that is popularly used for floor and roof framing in residential and commercial buildings. Here is everything you need to know about TGI in construction.

TGI is made by combining multiple pieces of wood into a solid beam, resulting in a stronger and more stable structure compared to traditional solid lumber. The pieces of wood are glued together and then mechanically bonded, ensuring a high level of durability. TGI beams are typically made from softwood, such as spruce, pine, or fir, and come in various sizes and lengths to accommodate different construction needs.

One of the main advantages of using TGI in construction is its ability to span longer distances without the need for additional support columns or walls. This allows for more open and flexible floor plans, as well as reduced construction costs. TGI beams are also lightweight, making them easier to handle and install on-site. Additionally, TGI beams are designed to resist warping, shrinking, and splitting, ensuring a longer lifespan for the structure.
