Custom-built steel structures and welded assemblies for mechanical engineering and industry – built to your drawings and specifications.

Tomasic's steel construction is used wherever load-bearing structures, frames or assemblies are needed for machines and plants — from individual conveyor technology frames to complete plant housings. We also manufacture steel structures as standalone contract work outside our own special-purpose machines, built to customer drawings.
For the food industry and other sectors with high hygiene requirements, we also supply steel components in stainless steel.
Our manufacturing depth ranges from design through cutting and machining to welding and on-site assembly — in stainless steel as well as steel and other materials.
Finishing steps such as surface treatment or galvanising are not part of our own capabilities. For these steps, we work with specialised partner companies.
As a special-machine builder with our own manufacturing depth since 1994, we don't treat steel construction as isolated contract work, but as an integral part of plant engineering. This gives us an understanding of tolerances, loads and assembly requirements that pure steel construction shops often lack.
For a quote, we generally need your technical drawings, the required materials and tolerances, and details on the quantity needed and delivery date. The more detailed the documentation, the more precisely we can prepare your quote.
Yes, alongside standard steel, we also manufacture in stainless steel, for example for applications in the food industry with high hygiene requirements. We clarify together which material suits your project.
No, surface treatment and galvanising are not part of our own services — we focus on the planning, manufacturing and assembly of steel structures, in both stainless steel and other materials. For finishing steps such as surface treatment or galvanising, we work with specialised partner companies.
Steel construction with Tomasic makes sense both for one-off items and small batches — we manufacture from a single assembly to a larger series. The specific economics depend on component complexity and quantity, and are factored into the quote.
