Coil and Coil Purchasing

Englert provides a painted coil product with the best reputation in the industry for consistency of quality and performance.

The metal and aluminum coil in Englert’s roofing and gutter products is made from the highest quality materials available. And it is 100% recyclable. We hold our suppliers to the strictest of standards and employ a rigorous qualifying process in selecting new sources.

A sophisticated data acquisition archive, and the use of a laser to imprint the company logo and tracking code on every roll of coil, provides a “recipe builder” for future jobs for the same customer, and eliminates potential errors on re-orders

Finally, we take care of our customers. We encourage them to know how to purchase coil and sell their products for the right price, and have developed simple charts and formulas for their use in calculating lineal feet and other measurements.

Roofing Coil Calculators


Calculating Cost Per Foot

As a contractor, you are purchasing gutter coil materials by the pound, and you are selling it by the foot. It is important to know what gauge material you are receiving. For example, over gauging by one thousandth of an inch could cost additional money per pound.

There is a simple chart contractors can follow to identify the cost per foot and make certain the coil they are using has been accurately weighed at the factory.

  • 025 gauge x 11 ¾”2.865 feet per pound
  • 027 gauge x 11 ¾”2.653 feet per pound
  • 032 gauge x 11 ¾”2.238 feet per pound
  • 027 gauge x 15”2.078 feet per pound
  • 032 gauge x 15”1.754 feet per pound

To find out the cost per foot, each pound of gutter material should produce a specific amount of footage. As you can see from the chart, 025 gauge will produce 2.865 feet of gutter per pound. To find the cost per foot, divide the cost per pound by the yield factor for the specific gauge. For example, at $2 a pound for 025 x 11 ¾”, the coil is costing the contractor 70 cents per foot.

Calculating Cost Per Pound

If a contractor is purchasing material for a low number per pound, it is important check the material to make sure the weight of the coil is accurate. Few installers have a large enough scale to weigh a coil in excess of 500 pounds. But our same formula for yield can be used to verify what a coil truly weighs.

By keeping accurate records of the number of feet run off on a single coil, a contractor can then divide the total number of feet by the gauge yield factor to determine the accuracy of the weight. For example, 1,000 feet of 027 gutter divided by the yield factor of 2.653 feet per pound equals 376 pounds of gutter coil.

Price is important. but equally important is knowing what you are buying. At Englert, you can be sure you are paying for the very best coil products and service support in the industry.


Material Conversion

As an Englert metal roofing manufacturer, you must understand that the amount of coil you purchase is not a direct indicator of the square footage of roofing panels you will manufacture. In the panel manufacturing process, your machine uses a portion of the flat coil to form the standing seams. Englert refers to this as Panel Coverage versus Material Usage.
