Industrial Frame and Support Structures

We deliver strong and precise steel structures for industrial needs. These structures can be machine frames, support structures, bases or other critical assemblies subject to continuous stress. We take part in systematic manufacturing where each joint and dimension is made with durability and safety in mind. The structures are produced according to the customer’s drawings, tested, and documented.

Industrial Pipelines

We manufacture and supply various industrial pipelines suitable for, among others, the process industry, energy industry, and mining industry. Pipelines are fabricated with high accuracy and tailored to the customer, taking into account material requirements, connection techniques, and any surface treatments. Welding is performed with methods appropriate to the task, and if necessary, we include pressure testing and inspection reports. We also offer assembly and pre-installation.

Dust and Smoke Extraction Ducts

We provide duct solutions designed for dust and smoke extraction in industry. These structures are designed and built to withstand harsh operating environments as well as possible chemical and thermal stresses. We implement ducts and components with precise measurements, and if needed with beveled or rounded designs. We have manufactured both individual parts and large duct systems for several different industrial sectors.

Silos, Tanks, Platforms, and Stairways

We supply silos, tanks and various platform solutions tailored to our customers’ needs. Tanks can be non-pressurized or pressure-bearing, horizontal or vertical, and we deliver them either as individual units or as part of a larger turnkey delivery.

Stairs, platforms and railings are always designed according to the site, with work safety and ergonomics as priorities. The structures are made durable, easy to install and, if needed, removable. We can also implement special structures and site-specific solutions that require experience, precise measurement and sound structural design.

Transport Containers and Lifting Devices

We manufacture various steel structures for transport and lifting, such as transport containers, lifting frames, and custom-fabricated support structures.

Each product is designed according to its intended use, taking into account load requirements, lifting points, stackability, and fastening solutions.

We have delivered both standard-compliant and customized lifting devices for use in machine shops, mining equipment, and offshore applications. The lifting solutions can be tested, equipped with the necessary identification plates, and documented in accordance with regulatory requirements.

Flanges, Hatches, and Valves

Critical connection points of machines and processes – such as flanges, hatches, and valves – are manufactured by us with high precision and according to material requirements. These parts can be part of a larger delivery package or delivered as individual spare components.

Typically, we produce solutions machined from plate and blanks which may include threaded connections, weldable fittings, or sealing surfaces. If necessary, we ensure functionality with test assembly or measurement reports. We can also produce replacement parts for originals based on drawings or a sample piece.

Conveyors, Conveyor Drums, Rollers, and Roller Sets

We manufacture conveyor solutions designed for industrial material handling along with related components. Conveyors can be chain, belt, or roller conveyors, and they often utilize our in-house made drums, rollers, and sets of rollers.

We deliver solutions for both continuous inline conveying and special purposes that require custom dimensions, mechanical durability, or welded assemblies. We can manufacture the entire conveyor structure or a sub-assembly according to the customer’s wishes.

Support and Rope Wheels

We produce support wheels and cable car sheaves needed for mechanical power transmission and lifting, in various sizes. Typical applications include lifting and transfer devices, mining and port equipment, as well as process industry systems.

The structures are made as required by the application from machined blanks or welded parts. Diameters, groove depths, bearings, and attachment methods are defined on a case-by-case basis.

Shafts, Bearing Housings, and Pedestals

We machine and manufacture shafts, bearing housings, and pedestal structures according to drawings. Production covers both turned and milled forms, with through-holes, keyways or combined surfaces as needed. Bearing housings can include mounting holes, grease channels and protective features. Pedestals are usually implemented by welding and finish-machining the critical surfaces.

Couplings and Other Machine Parts

We supply various machine components, such as couplings, sheet metal parts, protective structures and adapter pieces. These parts are often produced as part of a larger machine assembly, but we can also deliver them as separate replacement parts. Implementation can include welding, machining, heat treatment or surface treatment, depending on the application.

Horizontal and Vertical Components of Drilling Equipment

We manufacture components belonging to earth drilling machinery, such as horizontal and vertical spindle bearings, support structures in frames, and power transmission parts. These parts are often large and require both mechanical strength and high-precision machining. Production is carried out in close collaboration with the customer.

Wear-Resistant Steel Parts for the Mining Industry

We supply various wear-resistant parts to the mining industry, such as wear plates, guides, guards, and wear shoes. The parts are made from hardened or specially coated steels, and can be enhanced with mounting points, bevels, or cut-to-shape edges. Manufacturing is based on precision and material knowledge so that the wear properties meet the conditions of the application.
