Our success is measured by how well we satisfy our customers’ needs, and their success.
Steel structure is the cost leader for most projects in materials and design. It is inexpensive to manufacture and erection, requires less maintenance than other traditional building methods.
Designed and fabricated in-house with strict quality control. The fabrication process includes design and engineering, as well as detailing and manufacturing at the factory.
All steel components are fabricated at factory and are linked by bolts at site. So the erection process is fast, step by step, easy to install and require simple equipment.
Pre-engineered steel buildings are flexible in any requirement of design, easy to expand in the future and also economically with low transportation cost.
Nowadays, pre-engineered buildings are the green solution for the environment with CO2 reduction, energy efficiency and recyclability.
Steel can withstand strong winds, earthquakes, hurricanes and heavy snow. They are also unreceptive to rust and not affected by termites, bugs, mildew, mold and fungi.
