The GLUS range of rebar couplers provides a comprehensive selection of mechanical connections suitable for a wide variety of construction applications, including precast concrete, bridges, tunnels, and high-rise structures. Each system is designed to deliver high strength, easy installation, and full compliance with international rebar connection standards.

Threaded Couplers

GLUS Thread Couplers provide a strong and reliable rebar splice suitable for most reinforced concrete applications. Bar ends are cut square and threaded in parallel to fit the coupler sleeve. Installation is completed by tightening with a pipe or chain wrench. The system ensures 100% bar strength and precise alignment under tension and compression.

Cold Extrusion (Squeezing) Couplers

The Cold Extrusion Couplers are designed for use where threading or welding is not practical. After inserting the rebars into the sleeve, a hydraulic press squeezes the coupler body to mechanically grip both bar ends. This system provides a highly reliable, full-strength connection and is widely used in bridge, tunnel, and foundation projects.

Axial Cold Extrusion Rebar Couplers

The Axial Cold Extrusion Coupler is an enhanced version of the squeezing type, applying axial compression to ensure uniform deformation and superior bonding. It is particularly suitable for large-diameter rebars and seismic structures requiring consistent performance under repeated load cycles.

Mechanical Bolted (MBT) Couplers

The MBT Coupler range is used when bar end preparation is not convenient. Rebars are clamped onto serrated saddles within the coupler body and locked securely using a series of lockshear bolts. This connection type is ideal for repair works, retrofit projects, and situations where on-site threading is not possible.

Grouting Couplers for Precast Elements

The Grouting Coupler provides a mechanical connection using a specially formulated grout. Designed primarily for precast concrete element connections, it accommodates rebar alignment tolerances and phased construction requirements. The system ensures full structural continuity between precast units and cast-in-place concrete.

One Touch Couplers

The GLUS One Touch Coupler is designed for rapid installation without threading or special tools. Rebars are simply inserted and locked with a single pressing action, achieving an instant mechanical connection. This system is ideal for projects requiring high-speed assembly, such as precast production lines or tight-schedule site work.
