Stainless Steel Castings for Building Facade Systems

Client Overview

Our client is a leading building solutions provider specializing in high-end building facade systems. They required high-precision stainless steel castings, specifically curtain wall spider fittings, to meet the stringent structural and aesthetic requirements of a landmark commercial building in Europe.

Challenges

1. Complex geometry: The spider fittings require complex designs to ensure load-bearing capacity while maintaining a smooth aesthetic.
2. Material integrity: 316L stainless steel was required to be corrosion-resistant in coastal environments.
3. Dimensional tolerance: Tight tolerances (±0.1 mm) were critical to ensure seamless assembly with glass panels.
4. Surface finish: A mirror-polished surface was required to match the high-end design of the building.

Our Solution

As a trusted stainless steel precision foundry, we provide end-to-end expertise:

- Design Optimization: Work with customer engineers to optimize 3D models and improve castability without compromising strength.
- Advanced Casting Process: Investment casting (lost wax) is used to obtain near-net-shape parts with minimal post-processing.
- Quality assurance: X-ray inspection, dye penetrant inspection and mechanical testing to comply with ISO 9001 and EN 1090 standards.
- Surface enhancement: Electropolishing process to obtain a uniform, corrosion-resistant surface.

Results

- 100% on-time delivery: 8,000 custom curtain wall spider parts were shipped in 4 batches within 6 months.
- Zero defects: All parts passed third-party load testing (compliance with EN 1991-1-4 wind load standard).
- Cost savings: Processing costs were reduced by 30% through near-net-shape casting.
