The main framework of a structure is called truss which consists of struts, rafters, posts and bridges. They carry five or even more triangular components, containing flat units connected by the joints or also known as nodes. Various kind of materials can be used in the fabrication of trusses and they help to create architectural diversity.
Buildings are dependable on trusses for increased reliability, strength and durability. Steel can be accepted as one of the wise choices due to its versatile and flexible nature.
Why Steel Is a Good Option for Trusses?
Typically, in every construction project, contractors find themselves on the horns of a dilemma whether selecting which option makes more sense in trusses: Steel or wood? Wooden trusses usually benefited in the residential houses while trusses of modern buildings mostly made out of steel. Wood has major weakness since the moisture content decrease in time, which decreases its toughness. Delays occurred in the project put wooden trusses in the risk of rotting, warping and infestation.
Unlike wood, steel is not an organic material. Therefore, such problems are impossible to encounter in steel trusses. Advanced technology presents low density and high strength modern steel trusses to builders. Computer-assisted engineering methods enable producers to make regular and intricate shaped trusses rapidly, with high precision and quality. Furthermore, steel trusses are immune to bad weather and nasty conditions. It will neither deform nor lose its properties by itself. In terms of cost cutting measures, pre-assembled steel trusses help to save time and money.
By reaching high standards, steel became a material of choice for engineers due to its various advantages. Architectural beauties seen on commercial and residential buildings, stadiums, malls, museums and more partially owe their appearance to possibilities brought by usage of steel trusses. Long service life, design flexibility, advanced integrity of structure, capability to withstand heavy loads makes them one of the indispensable components of structures. They are available in a broad spectrum of kinds, geometries, dimensions according to different applications.
The Production Process of Steel Trusses
Complicated production process of a steel truss requires special tools, skills and methods to create particular end products as desired. This process is divided in three main steps: cutting the raw steel, forming the shape and assembling the parts. Various different cutting tools, including high technology water jets, plasma and laser cutters. Saws are used for simple straightforward cuts while plasma and laser cutters are used to cut intricate geometries.
Forming process starts right after cutting. Trusses are press baked and rolled to obtain desired shape. These two methods enable fabricator to produce an extended range of sizes and geometries. Different types of trusses are fabricated according to customer demands. For instance, metal studs in C-shape is used in roof trusses.
In the last step of production process, fabricated parts are assembled according to technical blueprints. Producer must be very well acquainted with the type of trusses, exposure of wind, span, purpose of use, desired slope to execute assembly operations accurately. These operations include welding and connecting the parts together to be ready to fulfill its duty as a support member. Software programs are utilized by the producer to meet the expectations of the buyer. Optimum properties can be achieved by an experienced producer. The target is to create the truss as lightweight as possible without giving up on the integrity and stability of structure. At the same time, they must comply with the standards.
Customized Steel Trusses
Buyers sometimes prefer customized steel trusses to meet the design requirements of their projects. Such designs in which a more appealing appearance is aimed, builders may have to seek for eccentric pieces of support types. Steel trusses are able to encompass all the needs of buyers. They are highly adaptable for various kinds of designs thanks to the high technology steel truss production methods used in cutting, forming and assembly steps. Steel truss is the right answer for a demanding project.
