Production workflow and shop travelers · Lesson 2 of 4

Production workflow and shop travelers: materials, standards and design constraints

The material facts a traveler must state, the AFS limits and status check that gate the queue, the coating maker's rules that travel with the job, and how metal is stored between operations.

You will be able to: Write the material line of a traveler, apply the limits and bend rules that decide whether a job can be queued, and carry the coil maker's handling and storage rules with the job.

Slide 1 of 11

The material line

Every traveler states the material, its thickness in its own unit, the colour and which side is painted. AFS sizes thickness by material:

Galvanized and stainless steel: 26 to 16 ga
Aluminum: 0.018 to 0.080 in
Copper: 16, 20, 24 or 32 oz
Zinc: 0.7 or 0.8 mm

AFS quote approval sends each FlashDraft profile to PathfinderEdge for AFS's Thalmann folder: legs, bend angles and hems; a person checks the machine file before it reaches the folder; painted side confirmed in 3D - Architectural Flashing Supply

Glossary

Girth: The total flat width of the blank. AFS shows it as Blank Width, a quoting figure: the legs to the mold line plus an approximate allowance for each hem, not a measured cut width.
Shop review: The fabrication status that means AFS confirms the profile before it is fabricated.
Strippable film: A temporary protective vinyl on prefinished metal; PAC-CLAD has it removed before or right after installation.
FIFO: First in, first out: the oldest stock is used first.
Wet storage stain: Staining of galvanized surfaces that the AGA advises preventing by avoiding tight stacking, removing standing water and keeping air moving.
