Steel Structure Characteristics
1. Versatile Aesthetic Options:
Steel structures open up a world of aesthetic possibilities. With modular components, we can construct unique geometric shapes, like curved facades or multi - level cantilevers.
Additionally, steel can be easily integrated with other materials such as glass and wood. This versatility allows for a harmonious blend of functionality and beauty in any building project.
2. Enhanced Fire Safety Features:
To boost fire resistance, we don't just rely on coatings. Our steel structures are engineered with a combination of intumescent coatings and insulation materials.
In the event of a fire, the intumescent coating expands, creating a thick, insulating layer that protects the steel core.
This, combined with proper ventilation design, helps contain the spread of fire and gives occupants more time to evacuate safely.
3. Superior Thermal Performance:
For roofs and walls, we use advanced composite panels.
These panels are composed of multiple layers, including insulating foam cores and high - strength outer skins.
They provide excellent heat insulation, reducing energy costs for heating and cooling.
