GALVANISING REPAIR STICK

We also supply  zinc sticks for repairing damaged finished items, where the galvanising has been damaged.

It is similar to the Zilt stick, an alloy of Tin, Lead and Zinc.

Method of use:

If the item to be repaired has just come out of the galvanising bath, and still hot, the zinc stick can simply be rubbed over the damaged area.

If the item is cold, the damaged area is heated up to approx 200°C do not exceed this temperature as this will damage the sound galvanised surface.

Heat up the end of the zinc stick with a blow torch or similar until it starts to melt, then rub the zinc stick on the damaged surface as required. 10 zinc sticks per kilo (minimum order) approx 250 mm long x  9 mm thick, 100 gms.

Store zinc sticks in a cool, dry well ventilated area.

As far as we know, this is the only place you can obtain these zinc sticks in the U.K.

Uses

Bending rolled or extended sections

Press tools small or large

Casting for reproduction of fine detail

Gas tight seals

Fusible plugs and links

Bending thin-walled tubing in copper, brass, mild and stainless steel.
