Steel Truss Design

Trusses 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

Steel trusses are used in many different ways. They can be used to support beams, columns, or roofs. Steel trusses are often used in construction because they are strong and durable.

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. They’re often used in place of more traditional steel beams or columns. There are many different types of steel trusses, each with its own unique features and applications.

Warren Trusses The most common type of truss

Warren Trusses are the most common type of truss. Warren Trusses are triangular in shape 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.

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

Pratt Trusses: Used extensively in bridges

Pratt trusses were among the first truss bridges ever built and are still in use today. They are named for their inventor, Theodore Pratt. Pratt trusses are made of metal and are very strong. They are used extensively 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. The Howe truss was developed by Squire Whipple in 1840. The bridge is named after Henry Howe, who popularized the design. The Howe truss is made of metal and 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. They are used to support roofs and other structures and are often found 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

The Bowspring Truss is a new type of truss that is designed for large spans. It has a very simple design, and it can be made from standard lumber. The bow spring truss is strong and lightweight, and it can be used in place of traditional trusses.

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

Fink Trusses are a rare type of truss that is mostly used for roofs. They are made from metal and have 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 trusses 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 together using either welds or rivets. Steel trusses are often used in buildings, bridges, and other structures because of their stability and durability.
