The truss is constructing support members that allow you to cross gaps while equally distributing weight between the gaps. Trapezoid truss is so named because they are similar to ordinary ladders. These are commonly used in roof frames to impart cantilever rigidity. You can easily construct trapezoidal truss of almost any size or specification from construction timber. Ladder trusses can be made of wood or steel, depending on the needs of the building.
It is the simplest and cheapest form of the industry standard 50mm truss system. It is the ideal choice for buildings and structures where the maximum net span and load are less important than appearance or available space. For example, exhibition floors and retail displays, where the floor is a premium.
Trapezoidal truss has a variety of accessories, angled parts and straight length, so it is very flexible and can create a strong and reliable structure in a limited space. Although the cost is reduced due to the use of less materials, Ladder's performance specifications are sufficient for the operation of lighting and display systems in most professional situations.
