Manufacturing QA and continuous improvement: materials, standards and design constraints

Where a flashing job's acceptance criteria come from: the specification's quality articles and shop drawings, the edition of a referenced manual, what material makers say is and is not a defect, and the limits AFS checks every profile against.

You will be able to: Trace each acceptance criterion on a flashing job to the document that governs it: the contract, a referenced standard and its edition, the material maker, or the fabricator's own limits.

The documents that set acceptance

A defect is a departure from a written requirement, not a look someone dislikes.

One 07 62 00 section (Gelfand Partners, 2026) asks for makers regularly engaged in making similar items, with a history of successful production the Architect accepts.

It also asks for complete shop drawings with large-scale profiles of all sheet metal work.

Glossary

Shop drawing
The fabricator's drawing of the work, approved before fabrication. One published 07 62 00 section asks for complete sheet metal shop drawings with large-scale profiles of all sheet metal work.
Oil canning
The Metal Construction Association's term for visible waviness in the flat areas of metal roofing and metal wall panels; MCA says no maker, fabricator or installer can assure its total prevention.
Wet storage stain
The American Galvanizers Association's term for a bulky white or gray deposit formed by accelerated corrosion of a zinc coating, when new galvanized items are stored damp, closely packed and poorly ventilated.
SHOP REVIEW
One of AFS's three design-check statuses (OK, SHOP REVIEW, BLOCKED). The profile can be submitted, and the customer is told: "AFS confirms this profile before fabrication."
