Dear colleagues,
We've received the first sample of our 10-wire PC strand with 14.8 mm diameter - the analogue of 12.5 mm 7-wire strand.
The previous parties (right sample) are 11.5 mm.

The future is coming!
Last night we've stranded the small party of 14.8 mm trihedral 10-wire PC strand.
The larger diameter increases the effect of replacing standard PC strands.

The worker painted the empty place, because she didn't see the trihedral strand on the dry slab due to the lack of end slip.
And, of course, there is no end slip after the destruction of the slab!

The HC slabs with fantastic 42.5% economy of steel were successfully tested!

We'll be in Jakarta from October, 3 to October, 5.
We wish to speak about use of new reinforcement in SouthEast Asia with experts interested in innovations and decrease of expences.

Dear colleagues,
The report about extra-bonded 10-wire PC strand and its tests in Russia and Europe will be presented on the first day of the FIB Congress in Melbourne, October 8 at 11-45 am.

Here are the specialized anchor grips for our PC strand from the first industrial party.
The grip was invented by our team, manufacturing technology was developed and realized by our partners.

Here is the difference in shear capacity and character of destruction between the hollowcore slabs reinforced by indented 7-wire PC strands and Armasteel extra-bonded 10-wire PC strands:

New party of extra-bonded PC strand is prepared for tests.
We've produced about 6000 meters of 10-wire PC strand with 11.5 mm diameter (the analogue of 9.3 mm 7-wire PC strand) last week.
