Halfen Channel

• No risk of damaging concrete due to

hammer drilling• No damage to reinforcement

• No problems with oversized or shallow

holes

• No dust or noise from drilling• No waiting for chemical anchor resin to

harden

• No need for power supply

• Very fast and easy to install• Can be cast in close to concrete edges

• Multiple fixings possible at close spacing

• Reduced installation time for subsequent fixings

Advantages of cast-in channels

Halfen HDB punching shear

Why do you need punching shear reinforcement ?

Halfen HDB punching shear

• Faster to install than links

• Easy visual inspection

CE Marked

European Technical Approval with

Halfen HBS Couplers

It is easy to check the completed

connection for correct safe fitting

Can be fitted without torque wrench

Due to its slender shape increased

concrete cover and reduced

congestion

CARES approvals for normal

construction and Sellafield nuclear

approval

HBS-05 Reinforcement Coupler System

Halfen HBM Couplers

CRET Shear System

More efficient shear load transfer across

the movement joint than a simple dowel

Vertical anchor rods and support box

activate the maximum amount of the

slab

Fewer columns are required

More floor space gained

CRET

for longitudinal movement onlyCRET-V

for longitudinal and lateral movement

SBC

Halfen Balcony Connections

SBC

• SBC cast-in assembly

easily fixed to shutter

• Avoids complicated

modifications to

shuttering

Halfen Balcony Connections

SBC

• The thermal separator

minimizes the cold bridging

SBC

• The bracket gives horizontal

and vertical adjustment

• Bracket can be bolted, the

façade can be completed

and the balconies bolted on

at a later date if required
