Coil handling and finish protection · Lesson 3 of 4

Coil handling and finish protection: methods and worked application

A step-by-step method from receiving to shipping, the handling rules at each step, and a worked coil: weight per foot, length, PIW, outside diameter and pieces per coil.

You will be able to: Apply a documented receiving-to-shipping method to an incoming coil, estimate its length, outside diameter and piece yield with every input stated, and set its inspection points.

A documented method

This module's own method, built from the cited sources: nine steps for every coil, with a hold at receiving, identifying and finish inspection:

  • Receive, identify, store, stage
  • Feed and cut, form on AFS's Thalmann folder
  • Inspect the finish, pack, ship
  • Wet? Separate and dry it at once
  • Finish damaged? Touch up within limits, or remake; either way, inspect again
From receiving to shipping: the coil handling methodNine numbered steps run from top to bottom: receive, identify, store, stage, feed and cut, form, inspect finish, pack, ship. After receive, a diamond asks Wet; yes leads right to a box saying separate and dry at once, which returns to identify; no continues down. After inspect finish, a diamond asks Damaged; yes leads right to a box saying touch up within limits or remake; a touch-up returns to inspect finish, and a remake returns to feed and cut, so both are inspected again; no continues down to pack.

A flow of nine numbered steps from top to bottom: receive, identify, store, stage, feed and cut, form, inspect the finish, pack, ship. After receiving, a decision asks whether the coil is wet; yes leads to separating and drying it at once. After the finish inspection, a decision asks whether the finish is damaged; yes leads either to touch-up within the limits, which goes back to the finish inspection, or to a remake, which goes back to feed and cut and passes forming and the finish inspection again. Flags mark the hold points at receiving, identifying and inspecting.

1
Receive: check bands, wrap, edges and water; record it (hold point)
2
Identify: gauge, material, colour name and chart, finish face, against the queue card (hold point)
3
Store: indoors, chocked or racked, stack limits, first in, first out within the supplier's age limit
4
Stage: watch for condensation on cold coil brought indoors (GalvInfo); dry it before it is stored or fed
5
Feed and cut: padded contact points, burrs removed, cut away from finished stock
6
Form on AFS's Thalmann folder; film stays on if the supplier allows
7
Inspect the finish against the painted face ordered (hold point)
8
Pack: faces protected, no sealed wrap
9
Ship
The nine steps are this module's own method, built from the cited sources. Flags mark hold points: work does not move on until the check is signed. Touch-up limits come from MCA and the coil or panel supplier. A touched-up or remade piece is inspected again before it is packed.

Outside diameter (OD)
The diameter across the outer wrap of the coil.
Swarf
Hot or loose steel particles from cutting or drilling, which rust if left on a coated surface.
Chock
