FAQs for Sheet Metal Projects

This FAQ guide answers common questions about precision sheet metal fabrication, including supported industries, materials, in-house processes, tolerances, prototyping, quality control systems, lead times, KanBan programs, and international shipping.

Full traceability with ISO certification

Full traceability is critical in precision sheet metal fabrication, especially for regulated industries such as medical devices, semiconductors, photonics, and aerospace.This article explains how ISO 9001:2015 and ISO 13485:2016 certified systems ensure complete material traceability, process documentation, inspection records.

Surface finish standards

Surface finish in sheet metal fabrication affects far more than appearance. Controlled roughness, coating quality, and edge condition directly influence assembly accuracy, corrosion resistance, cleanliness, and regulatory compliance.

Weld integrity inspection

Weld integrity inspection ensures structural strength, dimensional stability, and cosmetic quality in sheet metal assemblies. This article explains common weld defects, inspection methods, HAZ control, and how Rollyu Precision integrates multi-stage weld inspection to meet ISO 9001 and ISO 13485 requirements.

Critical dimension checks

In precision sheet metal fabrication, not all dimensions carry equal importance. Critical dimensions—such as material thickness, hole location, flatness, bend angles, and fastener seating—directly affect assembly fit, functional performance, and regulatory compliance.
