Sigma DG 800 Series tie

Our Products

Fiberglass Form Ties 800 Series

The 800 Series form tie is perhaps the finest looking member of the Sigma Tie forming lineup.
It was developed for medium duty applications to give similar performance to the workhorse of the forming world, the 15mm Euro Rod (Dywidag Rod). Not all forming systems are designed to accept ties greater in diameter than 1" (25mm) and our new 800 Series is perfect for these demanding applications.
