Certified Steel Structures – ISO 3838-2 & EN 1090 EXC4

Quality is the core of our production philosophy. Our commitment is backed by globally recognized and mandatory certifications:

Structural Integrity Assurance

All steel structure manufacturing is carried out under the EN 1090-2 EXC4 certification. This verifies top-level production capability for components subjected to high dynamic loads, such as wind turbine tower elements.

Critical Welding Quality

Under the ISO 3838-2 Quality Assurance System, every welding operation (MIG/MAG, TIG) is rigorously inspected. Our certified welding engineers apply customer-specified WPS/PQR procedures to ensure the weld and heat-affected zone maintain maximum performance.

Customized Manufacturing & Delivery Solutions

As a metal fabrication company, our flexibility comes from adapting to your project schedule and technical needs.

Design-Driven Production

Whether transformer skid bases for solar plants, nacelle components, or blade connection parts, all customer drawings and material requirements (Carbon Steel, Stainless Steel, Aluminum) are processed with precision.

Wear & Corrosion Resistance

To ensure durability in harsh energy plant environments, we perform top-tier surface treatments such as Hot-Dip Galvanizing (DIN EN ISO 1461) and C5-grade industrial coating—fully controlled by our in-house quality team.

Logistics Alignment

Your products are delivered assembled or assembly-ready, depending on your site installation plan—always on schedule.
