Strucsol Ultrabar Composite helical bar thin bed joint | 4mm Diameter

Strucsol Ultrabar Composite Helical Bar | 4mm Thin Bed Joint | Crack Stitching & Masonry Repair

The Strucsol Ultrabar Composite 4mm is a next-generation thin bed joint helical bar - also known as a helibar, helix bar, or helifix bar - engineered specifically for crack stitching, brick stitching, and structural masonry repair in narrow mortar joints. Exclusively developed and manufactured by Strucsol, it delivers performance that stainless steel helical bars, helibars, and helifix bars simply cannot match - with 5x greater tensile strength, full corrosion resistance, and a significantly lower carbon footprint.

Recommended by structural engineers and designed for straight bed joint applications, this 4mm Ultrabar Composite is the strongest thin bed joint helibar available for helibar crack stitching repairs in brick, block, and masonry walls.

Why Choose Ultrabar Composite Over Stainless Steel Helical Bars?

• 5x greater tensile strength than equivalent stainless steel helical wire or helifix bars
• 4x stronger shear strength for superior structural performance
• 100% corrosion resistant - no risk of rust or long-term degradation
• 60% less carbon generated during manufacture vs stainless steel helical bars
• 4mm diameter - ideal for thin bed joints where standard 6mm helibars won't fit
• Lighter weight, easier to handle on site than traditional helibars

Applications

Ultrabar Composite 4mm helical bars are ideally suited to crack stitching and brick stitching repairs in thin bed joints where the mortar course runs straight with no bends or corners. Typical uses include:

• Helibar crack stitching in thin bed joint masonry
• Brick stitching and structural masonry repair
• Lintel and arch repair in narrow mortar beds
• High-load bed joint reinforcement where space is restricted

Important: Due to its high rigidity, Ultrabar Composite is not suitable for stitching around corners or curved bed joints (e.g. bay windows). For corner repairs, use our Stainless Steel Helical Bar instead. A combination of both helix bars can also be used - contact us for advice.

Exclusively Made by Strucsol

Ultrabar Composite was developed by Strucsol after years of R&D with the goal of creating helical bars that outperform stainless steel helibars and helifix bars on every structural metric, while reducing environmental impact. It is exclusively manufactured and sold by Strucsol.
