Hot-dip galvanising involves submerging steel parts into a molten zinc bath to produce a protective coating over the steel, by an exceptional longevity.
The zinc coating is not merely deposited zinc, it is metallurgically bonded to the base steel through a metal diffusion reaction that occurs between the iron and zinc.
Centrifuging takes place immediately after removal from the bath, and the deposited thickness is from 50 to 90 µm.
LRD-TS mainly uses spinning for this treatment, in order to treat small parts.
- Exceptional maintenance-free service life
- Full protection of the parts
- Dual electrochemical and physical protection
- The iron-zinc layer provides exceptional corrosion and abrasion resistance with good adhesion
- Unobstructed holes and drip-free parts
- The reliability of an industrial process complying with the NF EN 1461 standard
- A very cost-effective process
- Shiny parts
- Functional threads after treatment
Reminder : Hot-dip galvanizing process
- Fittings for buildings
- Lag screws & threaded fasteners
- Nuts and bolts, construction, railway, etc.
