Suitable Anodic Film Range – 0.0002”-0.0003” (5.08-7.62 microns.)
Exterior Standard 2
Suitable for applications requiring reasonable heavy abrasion and corrosion resistance with normal exposure to the elements.
Suitable Anodic Film Range – 0.0003”-0.0004” (7.62-10.16 microns)
Architectural Class I
Suitable Anodic Film Range – 0.0007” and Greater (17.78 microns and greater.)

Adhere
Most exterior grade products are available with Adhere on the backside. Additional charges and minimum order quantities apply to all products with Adhere. For additional information, click on the Adhere link to download the Adhere Brand Information Sheet.
High Strength Aluminum Options
Lorin now features MacPac-S products featuring a high strength aluminum anodized to your specifications. Not all gauges and widths are stocked. Inquiry through Sales / Inside Sales.
Material Inspection
Material is reviewed for visual consistency from edge to edge at a distance of 5 feet or 1.5 meters looking straight at the material hanging from a vertical surface.
Surface Protection
Lorin recommends that surface protection be applied to all specular / high reflective finish products as well as any anodized product with a thin anodic film to reduce surface scratching during the production process.
Visual Standards & Limitations
Due to deviations which are inherent to the raw aluminum surface, anodized aluminum products may display a range of color shades which do not indicate a product defect. Please confirm with your Inside Sales / Sales Manager if your order is for standard inventory stock or a specific product that requires consistency throughout. Aluminum finishes are directional by nature and may show a color shift or shift in visual appearance when viewed at different angles. Please communicate running direction at time of assembly or finished product production.

| Fabrication Characteristics |
|
Bending (Brake Press)
Handling pre-anodized stock has been found to be similar to handing other metals.
Half hard tempers are most often used because of their formability and structural integrity.
Where possible, use scrap material to adjust the depth of stroke required to accomplish the desired bend.
Gradual bending of the material will help to minimize crazing of the anodic film.
Strippable surface protection will protect the anodized surface during the bending process.
Laminating
Polyfilm surface protection is helpful and can be left on throughout the production process.
Clean the substrate with a clean brush prior to laminating.
Cut the sheet to size using sharp shears or a saw.
Consider experimenting with saw and feed speed on scrap material prior to full production runs.
Cut into the sheet so that the rough edges are on the back-side.
Spray-guide contact adhesives work best. Apply them on the anodized aluminum first, then on the core material.
Rollforming
In many cases, no tooling changes are required when transitioning from other metals to anodized aluminum.
Pre-anodized aluminum will take all minimum bend-radii as specified by the Aluminum Association.
As with other metals, tooling should be kept polished.
Chrome-plated rolls typically perform the best.
Using surface protection will sometimes eliminate the need for lubricants.
Stamping & Blanking
No major modifications in tool design are necessary.
Consider reducing male-female die clearance to 2%-8%.
Keep dies sharp.
A looping pit ahead of the press allows for smooth coil feeding.
Synthetic grippers on feed work best.
Lubricants may be eliminated, depending on the process.
Use link-less gloves when handling pre-anodized stock.
Anodized blanks are protected and stackable.
