Metal fabrication & gas ducts · Baltics & Finland
Custom metal fabrication and gas ducts
Beyond tanks, the leading European manufacturers we represent design and fabricate non-standard equipment to your specification, using a broad range of welding and metalworking equipment: flue and air gas ducts, metal structures and welded assemblies. Virasmart handles specification, manufacturing coordination and delivery across Latvia, Estonia and Finland.
What we fabricate
Non-standard steel equipment engineered and manufactured to your drawings, standard and volume. The categories below are the ones we specify most for Baltic and Nordic projects; other fabricated products are made to order.
Air ducts & ductwork
Air and ventilation ducting for process and building systems, from straight runs to complex routed assemblies.
Non-standard equipment
One-off equipment designed and manufactured to your technical specification when a catalogue product does not fit.
Metal structures
Fabricated steel structures, frames and supports for plants and installations, in stainless or carbon steel.
Large welded assemblies
Large-diameter shells, cones and welded assemblies produced on rotators and specialised welding equipment.
Custom fabrication
Design plus manufacture: cutting, rolling, welding and finishing of steel products to drawing, with the documentation the project needs.
European manufacturing
We work with manufacturers whose fabrication is engineered and certified to the project, using a broad range of welding and metal-processing equipment.
Broad fabrication capability
A wide range of welding and metalworking equipment covers not only cylindrical vessels but ducts, structures and non-standard products.
Design and manufacture to spec
Equipment is engineered to your drawings and technical specification, not picked from a catalogue.
Certified quality
ISO 9001 quality management with a controlled process from design through welding, surface finish and factory acceptance.
