What is Truss?

A truss is a rigid structure made by joining straight members at their ends to form triangles.

Definition

A truss is a rigid structure created by connecting straight members at joints to form triangles. This shape helps support loads while keeping the structure stable when under tension and compression.

Purpose

Trusses are used to cover wide spaces using less material than solid beams. They provide strong structural support without the need for many internal columns, which makes them useful for creating open layouts.

Examples of Use

Commonly used as roof trusses to support roofs in residential, commercial, and industrial buildings.
Used as floor trusses in structures where larger open layouts are needed.
Helps bridges support weight across long distances.
Found in warehouses and factories with large open interiors.
Used in stages and lighting frames because they are strong while still being relatively lightweight.

I-Beam

An I-Beam is a structural steel member with an “I”-shaped cross-section, designed to efficiently carry heavy loads by maximizing strength while minimizing material use.
