In the year 1986, Lichtgitter GmbH took over the Sulz galvanising plant together with a connected plant for the production of perforated metal planks. Over the following years, we dismantled the existing plant and replaced it in 2009 with a completely new galvanising plant in accordance with the latest technological developments. Due to the advanced fluxing agent treatment which is gentle on resources, the Federal Environmental Agency has provided a substantial amount of funding for the plant. Today, the Sulz galvanising plant is, due to its high quality standards, a constant for the steel-processing branch in the south-west of Germany.



Our solutions at the Sulz site
Hot-dip galvanizing
Hot-dip galvanizing creates a durable, robust layer that protects components from corrosion by immersing them in liquid zinc.
Powder coating
Powder coatings have a high scratch resistance and long durability and are even more environmentally friendly than other coating processes.
Centrifugal galvanizing
Centrifugal galvanizing is the solution for galvanizing and small parts. Centrifugal force is used to remove excess zinc from small components such as screws or bolts.
Duplex systems
Duplex systems combine galvanizing with additional coating and ensure a longer protection period. They also deliver aesthetically pleasing results.
