These Forgefix Threaded rods are bright Zinc Plated for increased corrosion resistance, and provide a cost effective fastening solution for many varied applications. They can be used with many other products including Drop In Anchors and Masonry Anchor Shields. Conform to DIN 975 standards. APPLICATIONUsed widely in the soft furnishing trades where strong timber connection is required. Also extensively used in Playground and Climbing Wall manufacturing.Ideal for use in chemical fixing applications where non standard sizes are required. Zinc coatings prevent oxidation of the protected metal to create a longer lasting finish. It does this by forming a barrier and by acting as a sacrificial anode if this barrier is damaged. Zinc oxide is a fine white dust (in contrast to iron oxide) does not trigger a breakdown of the substrate’s surface integrity as it is formed. The zinc oxide, if left intact, can act as a barrier to further oxidation, in a way similar to the protection afforded to aluminium and stainless steels by their oxide layers.
