The steel frame features a robust portal design, comprising steel columns, beams, and bracing. This configuration creates a fully enclosed building capable of withstanding severe weather conditions, including strong winds, heavy rain, and snow.
In our workshop, metal components are produced through a controlled process of cutting, welding, drilling, and painting before being delivered to the construction site. Each component is bolted for assembly, enabling quick and convenient installation that helps significantly reduce labor costs.
- Tension Members: Designed to withstand tensile forces
- Compression Members: Engineered to support compressive loads
