Details
The design of the ACS Tension 520 allows it to take an increased capacity than most of the systems available on the current market. It is available in diameters M10 through to M100 in carbon steel and stainless steel.
The performance characteristics of the ACS Tension 520 system can be seen in the product details below.
Thread | Units | M10 | M12 | M16 | M20 | M24 | M30 | M36 | M42 | M48 | M56 | M64 | M76 | M85 | M90 | M100 |
Nominal Bar Diameter | mm | 10 | 11 | 15 | 19 | 22 | 28 | 34 | 39 | 45 | 52 | 60 | 72 | 82 | 87 | 97 |
Min. Yield Load | kN | 25 | 41 | 77 | 122 | 176 | 284 | 411 | 566 | 746 | 1030 | 1360 | 1985 | 2531 | 2862 | 3585 |
Min. Break Load | kN | 35 | 52 | 98 | 155 | 223 | 360 | 522 | 719 | 946 | 1308 | 1727 | 2520 | 3212 | 3633 | 4551 |
Nominal Bar Weight | (kg/m) | 0.5 | 0.8 | 1.4 | 2.2 | 3.0 | 4.8 | 7.1 | 9.4 | 12.5 | 16.7 | 22.2 | 32.0 | 41.5 | 46.7 | 58.0 |
Mechanical Properties
ACS Tension 520 bar system has the following mechanical properties:
Minimum Yield Stress | 520 N/mm2 |
Minimum Breaking Stress | 660 N/mm2 |
Minimum Elongation | 19% |
Minimum Charpy Impact Value | 27J @-20?C |
Young’s Modulus | 205 kN/mm2 |
Adjustments within each fork or spade are:
M10 to M56 | +/- 1/a thread diameter |
M64toM100: | +/-25mm |
Turnbuckles give additional adjustments of:
M10 to M24: | -f/-25mm |
M30 to M100: | +/-50mm |
In addition, special turnbuckles with a higher adjustment are available on request.
Corrosion Protection
ACS tendons can be supplied with a blank, primed, painted or dip galvanised finish. If required hot-dip galvanising can be applied to tendons after the threading process. The threads are then brushed to remove any excess zinc.
The colour of the galvanising may vary along the length of the tendon. The appearance may also vary between the fork and bar by virtue of differences in the material composition.
Paint
For architectural purposes, it is recommended a painted finish is applied on top of the galvanising. Resulting in the corrosion of the bar being reduced.
Approved by DIBT Berlin
The ACS Tension 520 Bar System has been approved in Germany by Deutches Institut Fur Bautechnik. The approval covers the minimum yield load for diameters M10-M100 of the stainless and carbon bar system.
