Plain Round Steel Bar & Coil

Introduction:

Plain Round Steel Bar & Coil, also known as plain rebar, smooth steel bar, or round rebar, is widely used for reinforcement in concrete structures. Manufactured from HPB300-grade low-carbon steel, this product provides excellent workability, ductility, and bonding performance. It is available in two delivery forms: straight bars (typically 6–12 meters) and coils (continuous lengths wound into rolls). The straight bars are ready for on-site use, while the coil version is ideal for automated bending and prefabrication. Internationally, HPB300 corresponds to ASTM A615 Grade 40 and BS 4449 B500A standards, making it a reliable solution for residential, commercial, and civil engineering projects.

Advantages

Dual Form Supply for Flexibility

Clients can choose between straight bars for direct use and coils for automated processing. This versatility makes it easier to optimize materials and streamline logistics.

Excellent Bonding & Workability

Smooth surface enhances adhesion to concrete, and low-carbon composition allows for easy cutting, welding, and bending.

Time & Labor Efficiency

Using coils reduces off-cuts and increases speed in stirrup or cage fabrication. Straight bars save time for site-based installation.

Wide Range of Applications

Suitable for structural ties, slabs, columns, stirrups, and secondary reinforcement in all types of buildings.

Globally Accepted Standards

Backed by international codes, Yoshine’s plain round bars and coils are approved for use in construction projects worldwide.

Customization & Rebar Processing Services

Yoshine offers full-service rebar processing including cutting, bending, straightening, threading, and labeling. We process based on customer drawings or bar schedules, and provide estimation, detailing, and prefabrication for both straight and coiled forms. Our expert team supports efficient site preparation, reducing waste and improving installation time.
