Steel Truss Design

Steel Truss Design are a cost-effective and efficient means of creating roof support, spanning large distances while supporting the weight of the roof.


The main types of steel trusses and their applications

Many different ways utilize steel trusses. They can support beams, columns, or roofs. Construction often employs steel trusses due to their strength and durability.

There are many types of steel trusses, each with different applications and uses. Some common types of steel trusses include chord trusses, shear web trusses, orthotropic trusses, and composite steel/steel frame structures.

Beam Trusses:

Simple, economical, and versatile

Steel trusses are a popular type of construction for bridges, stadiums, and other large structures. Builders often use them instead of more traditional steel beams or columns. There are many different types of steel trusses, each with its unique features and applications.

Warren Trusses The most common type of truss

Warren Trusses are the most common type of truss. They are triangular and use metal beams to form the triangle. The metal beams are then joined together with metal plates and screws. Warren Trusses are very strong and can hold a lot of weight.

They are triangular metal frames that support the weight of a roof or other structure. Builders often use Warren trusses in conjunction with other types of trusses, such as king post trusses.

Pratt Trusses: Used extensively in bridges

Theodore Pratt invented Pratt trusses, among the first truss bridges ever built, and they are still in use today. They are named after their inventor, Theodore Pratt. Pratt trusses, made of metal, are very strong and extensively used in bridges. Steel trusses are a common structural design in many buildings.

Howe Trusses: Have a distinctive Z-shape

The Howe truss was the first metal truss bridge and it has a distinctive Z-shape.

Squire Whipple developed the Howe truss in 1840. They named the bridge after Henry Howe, who popularized the design. The Howe truss, made of metal, has a triangular shape. The top of the triangle is the deck of the bridge. The two sides of the triangle are the chords. The bottom of the triangle is the web or floor beam. The chords are attached to the web with verticals.

King Post Truss:

King post trusses are a type of roof truss that consists of two vertical posts and a horizontal beam. Builders use them to support roofs and other structures, and they are often present in churches and other large, historic buildings. King post trusses are very strong and can support heavy loads without failure. They are also relatively easy to construct, which makes them a popular choice for builders and architects.

Scissors Truss:

In 1849, an American architect named Asher Benjamin published a book called The Practical House Carpenter. This book included a new type of roof truss that he had invented called the scissors truss. The scissors truss is a two-level roof truss that has two triangular shapes that intersect at their peaks. This design makes the scissors truss very strong and stable.

Bowspring Truss: For Large Span

Engineers designed the Bowspring Truss as a new type of truss for large spans. Its design is very simple, and manufacturers can make it from standard lumber. The Bowspring Truss is strong and lightweight, making it suitable for use in place of traditional trusses.

Fink Trusses: A rare type that is mostly used for roofs

People rarely use Fink Trusses, a type of truss mainly employed for roofs. They make them from metal and give them a triangular shape. Fink Trusses are very strong and can hold up a lot of weight. They are also very efficient, which makes them a popular choice for many homes and businesses.


Steel Truss Design are a common type of construction and can be used for a variety of purposes. They are typically made from steel beams that are then connected using either welds or rivets.

Builders often use steel trusses in buildings, bridges, and other structures because they offer stability and durability.
