Steel structures are the most utilized system in high rise buildings and industrial structures. High measures of strength and flexibility has made steel structures more advantageous compared to concrete structures. Superior installation speed, ability to provide wide spans, high load bearing ability, aesthetic qualities, and adaptability to other structures are major preferences of steel structures. Given the need for precision and high quality construction, steel structures are required for the development of the construction industry in the country. With the aim of fabricating the highest quality steel frames under the supervision of skilled engineers and technicians, Daryan Engineering Group has established its steel fabrication factory. Having the most recent and efficient machines alongside most advanced technologies has provided the company with the capability to fabricate various medium to heavy steel structures constructible with both welded and bolted connections. Daryan Eng. steel factory is also capable of manufacturing space structures from top to bottom as well as producing steel deck plates.
