Production Scrap Factors
Coil Coating is a highly cost effective method of material decoration. We maintain ver low material processing scrap ratios in accordance with the following industry standard material spoilage schedule. Coil material free of camber, surface imperfections and tempered to a stable mid-A.S.T.M. hardness substantially reduces coil coating spoilage ratios. Please remember that soft material has a tendency to occasionally buckle and hard material has a tendency to snap.
Single pass production runs, net of slitting:
| 40,000# - Plus | Up to 2% |
| 20,000# - 39,999# | Up to 3% |
| 10,000# - 19,999# | Up to 4% |
| 0 – 9,999# | Variable % subject to job complexity & condition of coil |
- Pre-slit set-up will carry an additional 1.5% allowable scrap rate.
- Final slit set-up will carry an additional 3% allowable scrap rate.
- Vinyl metal laminates will require an additional 3% allowable scrap rate.
Please take into consideration an additional 3% post shipping scrap factor for roll forming.
What You Should Know About Painted Metal
Metal surface condition, preparation and treatment are all important factors to consider when painting metal. If moisture is permitted to rest on a coil of painted metal the results may be the rapid development of rust. White rust will attach to the paint surface causing undesirable marks and irregularities.
By practicing efficient material management, scrap factors shall be held to minimum levels.
Observe the following:
- Provide proper inside storage. Painted material stored outside is not guaranteed.
- Make provisions for adequate air flow in storage areas.
- During periods of extreme temperature change, provide heat to prevent concealed condensation.
- Storage beyond six months is not recommended and may result in damage to your painted material.
- Damage to the painted surface may result if formed parts are stored at the job site and are exposed to excessive moisture.
Cold Weather Forming
Forming of painted materials at temperature lower than 60 degrees Fahrenheit may produce unsatisfactory results.
During cold weather, pre-coated coil stock should be brought into the shop several days prior to fabrication to allow the material the opportunity to rise to room temperature.
If this is not possible, heater can be placed on-line, prior to the roll-forming operation, to evenly heat the strip. This adjustment in temperature will make the applied paint more elastic for crucial bending processes.
