Product Overview

High-strength steel reinforcement bar with a 20mm diameter and standard 3000mm length, used in heavily loaded concrete elements such as foundations, columns, beams, and large structural slabs. 

Made from carbon steel, the bar has a deformed surface with ridges that lock into the concrete, giving strong adhesion and reducing displacement under load. This ensures stability and improves the long-term durability of reinforced concrete.


The standard 3000mm length aligns with common reinforcement layouts, making it straightforward to plan and set out bars on drawings. This reduces errors at installation stage and supports consistent quality across reinforced elements.


At 20mm diameter and 3000mm length, the bar provides substantial tensile capacity in high-load and large-scale infrastructure, while balancing practical site handling.

Features & Benefits

  • Deformed surface with ridges: Locks mechanically into the surrounding concrete, improving bond strength, reducing the risk of bar movement, and enhancing crack control under load.
  • Carbon steel construction: Provides high yield strength and durability, ensuring reinforcement maintains performance throughout the service life of the structure.
  • Weldable before pouring: Allows bars to be joined or prefabricated into cages and mats, improving accuracy, speeding up installation, and reducing on-site labour.
  • Acts as a tension device: Offsets concrete’s inherent weakness in tension, improving resistance to cracking, bending, and shear stresses in reinforced members.
  • 20mm diameter: Provides substantial tensile capacity for heavy-duty reinforced concrete applications.
  • Standard 3000mm length: Practical size for handling, transport, and cutting on domestic sites.


Applications

  • Structural slabs: Reinforces heavily loaded slabs in commercial, industrial, and infrastructure projects.
  • Columns and beams: Provides strong tensile reinforcement in vertical and horizontal members carrying heavy loads.
  • Foundations: Strengthens deep foundations, pads, and ground beams for improved durability and stability.
  • Infrastructure works: Used in bridges, retaining walls, and large-scale structural elements requiring high reinforcement capacity.


Installation Guidance

  • Cut with suitable tools: Use a reciprocating saw with a bi-metal or diamond blade for clean, accurate cuts through heavier bar sections.
  • Maintain correct cover: Ensure adequate concrete cover for corrosion protection and to achieve reliable structural bonding.
  • Secure before pouring: Fix firmly with ties or welds to prevent movement during placement and vibration of concrete.

Compliance & Performance

  • Carbon steel reinforcement: Produced to recognised industry standards for structural use.
  • Service suitability: Appropriate for reinforced concrete applications requiring tensile strength.
