PRODUCT
Tianjin BRISK STEEL focus on produce and supply hollow section and steel pipe
Available Grades & Core Mechanical Properties
We provide four mainstream grades of ASTM A500 structural tubes (Grade B/C/D) to meet different load-bearing and structural strength requirements:
- Grade B: The most widely used grade with balanced strength and toughness, ideal for most building structures, steel frames, and conventional engineering projects (preferred for general structural construction).
- Grade C: Higher yield and tensile strength, applicable for medium and heavy-load structures, mechanical equipment supports, and outdoor engineering facilities requiring high durability.
- Grade D: Ultra-high strength grade with stable mechanical performance under complex stress, suitable for heavy-duty engineering, bridge auxiliary structures, and high-rise building key load-bearing components.
