Carbon Steel Square Bar 100x100mm to 600x300mm - JIS AISI 1084 4140 4340 ASTM A36 Q235 S235 Standards
Zhengde Steel Square Bar is a high-performance carbon steel material engineered for demanding applications across construction, machinery manufacturing, and logistics sectors. Manufactured to meet international standards including JIS, AISI 1084/4140/4340, ASTM A36, and Q235/S235 specifications.
- High carbon content for superior mechanical strength and durability
- Excellent toughness and plasticity for versatile forming applications
- Enhanced wear resistance and corrosion protection
- Available in hot-rolled and cold-drawn variants for different performance requirements
- Multiple standard specifications: 8#, 10#, 12#, 14#, 16# and custom sizes
Hot-Rolled Square Steel: Produced by heating billets to optimal temperatures and pressing through rolling machinery, delivering superior mechanical properties with slightly rougher surface texture.
Cold-Drawn Square Steel: Manufactured through cold-working of hot-rolled material, providing smooth surface finish with slightly reduced strength and toughness compared to hot-rolled variants.
