Brief introduction of truss structure
A truss structure is a structure consisting of triangular units made up of straight rods, usually used to support bridges, roofs, and other buildings. Truss structures can made of steel or wood. Steel truss is often used in long-span buildings and bridges require high load capacity. Wood truss is widely used in civil buildings.
Steel Trusses
For industrial plants, long-span buildings, Bridges, etc., steel trusses are usually able to withstand great loads and ensure the stability of the building structure. Steel trusses can be divided into ordinary, heavy and light steel trusses. The heavy steel truss is composed of H-shaped steel column or box-shaped steel column, and the joint is connected by two parallel joint plates.
Timber trusses
Wood Truss is a truss composed of wood components. It is the main load-bearing structure of wooden roof, wooden bridge and wooden tower. The main forms of the wooden frame are triangles, trapezoids and polygons.
The difference between steel truss and wood truss
Price
For large steel structure projects, the price of steel structure trusses is affordable. The price of wood truss is lower than steel trusses so that it is more suitable for residents.
Usage
The application of heavy steel trusses includes industrial buildings, long-span factory workshops, etc. However, the usage of wood trusses mainly in single-family homes and family warehouse.
Recycle
Steel is a recyclable and eco-friendly material. And the recycling of steel is convenient and fast. Recycling wood trusses requires a rigorous treatment process and stained, contaminated wood is not suitable for recycling.
Services time
A steel structural truss can last 50 to 70 yeas with low-cost maintenance. While a wood timber frame can last about 25 to 30 years. The service life of a wood truss is shorter than steel truss.

Based on the above comparison of steel joist structure and wood joist structure, you may have preliminary understanding of these two type of truss structures. Timber trusses are more suitable for residential construction. Steel trusses are more used in factories, stadiums, high-rise buildings. With the development of economy and society, steel structure has gradually become the main type of building structure. SYNERGIA is steel structure experts.
