Understanding Form Ties

CurlF fiberglass form ties mark a transformative shift in concrete construction techniques. By remaining embedded within the concrete, they eliminate the need for the disruptive post-construction removal process traditionally associated with metal ties. This not only results in a faster, cleaner finish but also significantly reduces the labor and materials usually expended in patching and repair work. These ties' innovative design allows for a quick saw-off, flush with the concrete surface, which then harmoniously camouflages with the structure, maintaining its aesthetic continuity. This method not only streamlines the construction workflow but also supports the integrity of the concrete by avoiding the introduction of potential stress points or entry paths for corrosive elements.

CurlF Fiberglass Form Ties(FRP Coil Rod System/FRP Formwork Tie Rods) whcih are produced by the pultrusion process technology and special mechanical production methods with high quality raw materials of reinforced glass fibers and vinyl ester or epoxy resin according to different application environments.

CurlF Fiberglass Form Ties can widely used to secure concrete formwork when doing concrete placement.Compared with steel tie rod,they not need remove from the structure when completing the project,so engineers can save big cost.

CurlF vs Steel

Machine-threaded form ties from CurlF are made from GFRP composites. The tie and nut are made to be easier to use

Easy to cut

CurlF is easy to cut, saving time and labour; Steel is difficult to cut and prone to fire, requiring stronger labor protection

4X Lighter then steel

1/4 the weight of steel for equal volume, CurlF composite form ties are more economical to transport.

Corrosion-resistance

CurlF composite materials never rust; Steel rusts easily, damaging the appearance of walls

Excellent thermal insulation

CurlF thermal conductivity 0.1~ 0.5w/mk

Steel thermal conductivity 36~54w/mk

Thermal Cycling Impact

CurlF thermal expansion coefficient closer to concrete than steel. Ideal for areas with extreme temperature cycles.

High Tensile Strength

CurlF twice the strength of steel

Why are CurlF form ties cost-effective?

CurlF form ties streamline projects, trimming labor and equipment overhead, thus offering a budget-friendly alternative to traditional steel ties. Employing CurlF GFRP composite form tie system markedly reduces expenses associated with labor, transport, materials, and equipment rental.

Eiminate patching

Not only results in a faster, cleaner finish but also significantly reduces the labor and materials usually expended in patching and repair work.

Steel form tie needs to be patched after being pulled out

Filling with cement requires a lot of labor

Rubber plugs require additional material

CurlF Formwork Ties Rod just cuts directly without patching

Transport Savings

1/4 the weight of steel for equal volume, composite form ties are more economical to transport. Quicker to unload when it arrives on-site.

Materials and Hireage Savings

• Equipment Hire Reduction: Decreased usage of scaffolding, elevated platforms, and lifting gear.

• Corrosion-Resistant Ties: Fiberglass rods blend with concrete, require no grouting post-cutting.

• No Additional Equipment: Eliminates need for grouting and preparation tools.

• Reusable Fasteners: The fastening nuts can be used multiple times.
