Highly Durable

The durability of prefabricated steel buildings makes them an ideal choice for builders, they are engineered using the strongest steel structure and the best quality materials, this type of buildings is carefully designed to endure the strongest storms and withstand extreme weather conditions. In addition to that, prefabricated steel buildings can last longer than wood and concrete structures, as steel is durable, non-combustible and almost maintenance-free. Most prefabricated steel buildings are engineered to stand the test of time and can last anywhere from 80 to 100 years.



Business owners find the cost of prefabricated steel buildings to be attractive as steel structures used can reduce the overall construction costs by 30% when compared to traditional brick and wood structures. Furthermore, the offsite manufacturing and engineering method of prefabricated steel buildings enable delivery ready to install components or units, this speeds up the construction timeline, allows the building to be occupied faster and increases project profitability as well. It also costs less to transport prefabricated steel building components or units from a factory than to buy construction materials, pay for labor, equipment, and utilities to build a new building.


Faster Construction

Construction industry has been always about speed and efficiency, prefabricated steel buildings are the most efficient and quick buildings. From inception to assembly the latest technology off-site prefabrication methods, machinery and materials are utilized to ensure delivery projects on time and on budget. Also, the speed of construction comes from the fact that all prefabricated steel building components arrive on-site cut, welded, drilled, painted and ready for a simple erection, this reduces significantly construction times and enables realizing quickly a return on investment and starting on another project on schedule rather than putting all the resources & efforts on one construction project.

When compared with traditional construction prefabricated steel buildings take less than half the construction time.


Quality control

Prefabricated steel buildings are factory-made and are designed and engineered under stringent quality control systems, the process starts from the production of structural steel in the steel mill, and ends with the building interior and exterior finishes. Prefabricated steel building passes through multiple inspections to ensure delivering accurate finished parts and hassle-free steel buildings.


Reduced Maintenance

Prefabricated steel buildings require virtually no maintenance, steel framing used won’t rot, split, or creep as a wood frame or concrete which requires ongoing maintenance against mold. This is due to steel inorganic and pest-proof nature which does not support the growth of mold, mildew, termite, fungi and rodent. In addition to that, all structural steel surfaces are treated against corrosion using cost-effective hot-dip galvanizing and protective coating can be also applied, this reduces significantly maintenance costs and eliminates repair, and replacement for the entire life of the building..


Environmentally Friendly

Prefabricated steel buildings offer many environmental benefits because steel is the most recycled material on the planet and can be 100% recycled and reused at the end of its service life. Also, the controlled manufacturing process minimizes the waste of natural resources such as energy, water and construction materials, while it reduces carbon footprint. In addition to that, prefabricated steel buildings are delivered ready for assembly, so, no construction waste, community disruption or pollution is created on-site during installation. Moreover, steel does not emit pollutants into the air and does not require any harsh chemicals for pest control.


Safe and Secured

Prefabricated steel buildings are designed and engineered to resist and absorb seismic activity and earthquake much more safely than any other material like concrete which can crumble and cause adverse effects and collapse. The highest strength-to-weight ratio steel is used to ensure structures are inherently ductile and can withstand loads imposed by high winds, rainstorms, heavy snowfall, hurricanes, and other challenges that natural force throws. Prefabricated steel buildings structures are fire-resistant, non-combustible and consequently do not burn in the event of an elevated fire. Furthermore, steel structures do not emit volatile organic compounds (VOCs) and offer better indoor air quality.



The versatility of steel provides architects the freedom to achieve the most ambitious design with clear span and free columns space; because of that, prefabricated steel buildings are used to construct the most iconic buildings in the World.
