We deliver quality

Supplier production at the highest level

MODERN MANUFACTURING

Experienced welders, high-performance CNC manufacturing, and one of Europe’s leading surface finishing processes enable the efficient production of sophisticated components and assemblies for industrial customer projects.

HIGH-PERFORMANCE LOCATIONS

Our manufacturing facilities are consistently designed for industrial projects—with state-of-the-art equipment, well-defined processes, and ongoing investments in machinery and personnel.

EXPERIENCED TEAM

At SPALECK, construction mechanics, machining experts, and surface treatment specialists work hand in hand—from simple laser-cut parts to the Assembly of components.

From a single part to mass production

Our Manufacturing Capabilities

Whether it’s a laser-cut part, a Welded assembly, or a ready-to-install unit: Our customers’ requirements for industrial metal fabrication are as varied as their products.

That is why we bring together the most important manufacturing technologies in metalworking and Machining under one roof. From precision components to large-scale Welded assemblies with crane capacities of up to 40 metric tons, we support your projects from prototype to series production. This ensures streamlined processes, close coordination of the individual manufacturing steps, and efficiency in solutions for our customers.

Laser cutting

The quality of many components is determined right from the cutting stage. Using state-of-the-art Laser cutting technology, we produce laser-cut parts with high dimensional accuracy and clean cut edges. Whether small sheet metal parts or large-format components measuring up to 2,000–6,000 mm: These precise cuts create optimal conditions for subsequent bending, welding, or Assembly of components.

Edges up to 14 meters: Precisely fitting bent parts, even for large structures

Large bent parts place high demands on manufacturing and handling. With bending lengths of up to 14 meters, we manufacture components for mechanical engineering, Plant engineering, and other industrial applications with precision according to drawings. This results in components that fit perfectly and can be reliably integrated into Welded assemblies and structures.
