HRB335 steel reinforcement is the most commonly used grade of steel reinforcement in concrete strengthening due to its stable yield strength, good ductility, and reliable bond properties with concrete. Typical applications include:
Residential and Apartment Buildings
What is Structural Reinforcement? Structural reinforcement is used in foundations, beams, slabs, and columns to ensure the safety and stability of the structure.
Commercial/Industrial Buildings
It is also suitable for factories, warehouses, workshops, and commercial buildings requiring stable load-bearing capacity.
Infrastructure Engineering
Used in bridges, roads, tunnels, and retaining walls to ensure the long-term stability of the structure.
Public and Civil Engineering
Frequently used in schools, hospitals, municipal buildings, etc.
Precast Concrete Components
Highly recommended for precast beams, slabs, piles, and various other reinforced concrete structures.
1) Branch Office - Spanish-speaking support, customs clearance assistance, etc.
2) Over 5,000 tons of stock in stock, with a wide variety of sizes
3) Inspected by authoritative organizations such as CCIC, SGS, BV, and TUV, with standard seaworthy packaging
Basic Protection: Each bale is wrapped with tarpaulin, 2-3 desiccant packs are put in each bale, then bale is covered with heat sealed waterproof cloth.
Bundling: The strapping is 12-16mm Φ steel strap, 2-3 tons / bundle for lifting equipment in American port.
Conformance Labeling: Bilingual labels (English + Spanish) are applied with a clear indication of material, spec, HS code, batch and test report number.
