Advanced Framing Techniques

In construction engineering, framing means joining together pieces of members to build a whole structure. Framing is the step where the construction project starts taking its shape. Wood, engineered wood, and structural steel are some of the framing materials used in construction. The framing technique is divided into two types, lightweight framing, and heavyweight framing. In the heavyweight framing, the vertical supports are few, and the size and weight of the pieces to be used are more like timber framing, pole building framing, and steel framing. Lightweight framing has several smaller size vertical pieces like a balloon, platform, and light-steel framing.
