Halfen
anchor channels are manufactured from channel profiles
with 1-anchors shop-welded to the back of the channels.
|
| |
They
are available in ready-to-use short lengths and continuous
lengths up to 20' - 0" (6.1m). Custom lengths
can also be manufactured to suit customer requirements.
|
| |
Halfen
anchor channels are available in hot dip galvanized carbon
steel and are foam filled. Stainless steel anchor
channels are also available.

 |
| REINFORCEMENT |
|
Halfen
anchor channels have been tested in unreinforced concrete and
no additional reinforcing is normally needed to carry the published
loads. However, the loads resisted by the anchor channels have
to be transferred into the surrounding concrete and the engineer
must ensure proper design of the complete system.

| SAFETY
FACTOR |
|
The
loads shown in the catalog are working loads and include a
safety factor of at least 3, applied to the ultimate strength
of the anchor channel or surrounding concrete.

| CONCRETE
STRENGTH |
|
The
load capacities of anchor channels shown are based on their
performance in 3,000 psi (20.7 MPa) normal weight concrete.
Some loads (marked *) are controlled by concrete strength and
can be increased for higher strength normal weight concrete,
up to a maximum of 5,000 psi (34.5 MPa) by applying a factor of:

 |
For
light weight concrete strengths up to a maximum of 6,000 psi
(41.4 MPa), apply a factor of:

TOLERANCES |
|
The
dimensions shown are nominal. Tolerances of ± 1/8" (3mm)
apply to lengths up to 12" (305mm) and ± 1/4" (6mm)
on longer lengths.
