ENGINEERING BOTTLENECKS
Every bolt must reach the same strength while thousands are made.
Groundwater and humidity shorten the life of unprotected steel.
ENGINEERED RESOLUTION
Automatic cutting and forming with samples tested from every batch.
A thick zinc layer protects the bolts for the whole support life.
