Step 1: Pre-Painted Coils

We purchase the 5-ton steel coils that meet our quality specifications directly from the steel plant. We ship them, first, to the coating facility, where the precoat and Sherwin-Williams’ top coat are applied, before shipping them to our warehouse. The coils are cataloged and carefully stored out of the weather — ready for use.

Step 2: Uncoiled

When an order is received, the coils are placed on the uncoiler that feeds the steel onto the rollformer.

Step 3: Heat Formed

For better performance, the ABM panel passes through a 1,000° Fahrenheit heat-box that warms the panels and temporarily softens the paint coating. This allows the paint to flex and bend with the steel as the panel is formed. Without heat-forming, the paint would crack and would likely rust. More on heat forming here.

Step 4 Imprinted for Quality Control

Each ABM panel is imprinted on the underlap with the order number, customer name, panel length, the date it was made, and the product grade (example: G-100 or Standard). This is how we are able to offer our low-hassle 40-year warranties.

Step 5: Cut-to-Length

The ABM panel is made to custom lengths within a 1/4” thanks to what we call the “flying sheer.” The flying sheer cuts the steel with amazing precision as it speeds down the line.

Step 6: Roll-Formed

The cut sheets go through a series of rollers with dies that form the steel into the ABM Panel profile. The ABM Panel comes with a 40-year paint warranty and can be expected to last even longer if properly maintained.

Step 7: Banded and Prepared for Shipment

A cover sheet (which often varies in color) is placed on top of the stack to protect the panels before the stack is banded together. A forklift transports the bundled panels to the customer’s waiting truck or trailer, or places it on the holding rack ready for shipment to the job site.
