1. The steel structure is convenient for transportation and on-site assembly, saving construction time, energy and cost.
2. Steel can be passed down from generation to generation.
3. Among all building materials, steel has the highest strength-to-weight ratio.
4. Steel pipes deliver clean water to our homes.
5. Steel has strong fire resistance and weather resistance.
6. Steel is durable and low maintenance cost.
7. Steel is flexible and easy to design.
8. The wide steel windows allow full sunlight to enter the house.
Let's get to know one of BBN's hot-selling steels that can be used for construction:
ASTM A573 Grade 70/A573 Gr.70 structural carbon steel plates are structural quality carbon-manganese-silicon steel plates in three tensile strength ranges intended primarily for structural applications at atmospheric temperatures for which improved toughness is required.
