Expected service life of a steel structure building
International building codes stipulate that a steel structure building should be designed for a service life of 50 years. However, quality steel structure projects can achieve 70 to 100 years of safe use. Weilan employs high strength steel, as well as rigorous structural design, to provide for service lives of 50 years for all of our steel structures. The high service life of steel structures also translates to a low life cycle cost for industrial and commercial buildings. Even after decades of use, many older steel buildings continue to function adequately.
The relationship between the quality of the material and the longevity of steel structures
Quality of Material is the predominant factor that determines the longevity of a steel structure. Weilan uses only CE certified Q235B and Q355B steels in their steel structure products. Such steel materials have high strength, good toughness, and strong corrosion resistance. Steel of poor quality rusts easily and reduces the longevity of a steel structure. Steel structures made by reputable factories possess consistent quality in their chemical and mechanical properties. Quality steel raw materials provide the foundation for a steel structure to have a long service life. To ensure quality, steel is tested in batches prior to production.
Treatment for corrosion on steel structures
Corrosion treatment is important on steel structures. Weilan offers services for various corrosion challenges on steel structures. For example, petrification of steel and hot dip galvanizing, along with epoxy zinc rich primers, are some of the surface treatments used for rust protection. The surface treatment of galvanizing steel protects the structural steel surface and creates a barrier against moisture and air. Quality corrosion protection can add more than 20 years to the life of a steel structure. Structural steel can be adapted to various environmental and climatic conditions when quality protection is provided. Regular inspections and maintenance of the protection system are required to assure the steel structure is properly maintained.
Design and Construction of Steel Structures
For a steel structure, a scientifically supported design and a meticulously prepared construction are fundamental. Weilan employs 32 engineers, both local and international, who specialize in steel construction. The team takes into account factors such as wind and snow loads and seismic ratings. Construction quality and the use of high-strength bolts are the factors that ensure the continuity of a structure. Poor design and construction will, definitely, reduce the life expectancy of the steel structure. Proper incorporation of all constituent parts guarantees that the structure will attain the desired service life. Construction of the structure will be performed with the utmost control over every single part of the steel structure.
Maintenance and environment of use of the steel structure
Daily upkeep and the environment where the structure is employed, will determine the steel structure’s life expectancy. If a structure is placed in a clean and dry environment, it will outlast the expectations of its design; however, if its placed in a humid atmosphere, where corrosive agents are present, the structure's life will be greatly diminished. Regular inspections and some form of maintenance will mitigate most of the abovementioned problems. Simple maintenance such as cleaning and repainting helps the steel structure resist corrosion. Weilan has a one-year maintenance free policy to provide guidance to steel structure users. If properly utilized, the structure will last longer than the design specs anticipate. Good maintenance improves returns on investment for users of steel structures.
How to extend the service life of a steel structure
Simple steps can be taken by the users to extend the service life of a steel structure. Users can choose quality steel structure products by reputable manufacturers such as Weilan. users can accept standard design and professional installation for the steel structure. Users can perform regular safety inspections and anti-corrosion treatments on the steel structure. Users can maintain the clean environment around the structure and avoid contact of the structure with corrosive substances for a long time. Users can repair damages and deformations of the steel structures without delays. These methods can help users to prolong the life of their steel structure buildings. Steel structures with a long service life provide users with lower costs and increased benefits.
