What is a square of panels?

A square is an area of 100 square feet.

How do I calculate my amount of squares?

You must know exactly how many panels you need, and how long each panel will be. Once you have determined this information, you can figure squares by this method:

  1. Arrive at a total length of all of your panels as if they were placed end-to-end. For example: 20 panels of 10’ 4” in length would be 206.6’ of the total length.
  2. If your panels are 3” coverage panels, multiply your total lengthy by 0.0317. This is your amount of squares. Round off your total to the nearest tenth of a square. 206.6’ x 0.0317 = 6.5 squares
  3. If your panels are standing seam or architectural types, multiply your total lengthy by the actual coverage of the panel and then divide by 100. 206.6’ x 2” coverage standing seam divided by 100 = 4.1 squares.
  4. The following multiplier should be used for their respective panels:
    Super Span & Low Rib .0319
    Cor Span .0283
    7.2 Rib .0325
    Weather Lok-16 / Weather Snap-16 .0133
    Shadow Wall-18 .015
    Sturdi Rib & Sturdi Span .0317
    Super Seam-II / Super Seam-Plus .02
    7.2N Rib .0269
    Accent-11 / Accent 11R .0092
    Weather Guard .01

What is "ASTM"?

The American Society for Testing and Materials.

ASTM is a not-for-profit organization that provides a forum for the development and publication of voluntary consensus standards for materials, products, systems and services. More than 32,000 members representing producers, users, ultimate consumers, and representatives of government and academia from over 100 countries develop documents that serve as a basis for manufacturing, procurement, and regulatory activities.

ASTM develops standard test methods, specifications, practices, guides, classifications, and terminology in 130 areas covering subjects such as metals, paints, plastics, textiles, petroleum, construction, energy, the environment, consumer products, medical services and devices, computerized systems, electronics, and many others. ASTM Headquarters has no technical research or testing facilities; such work is done voluntarily by the ASTM members located throughout the world.

More than 10,000 ASTM standards are published each year in the 73 volumes of the Annual Book of ASTM Standards. These standards and related technical information are sold throughout the world.

For more information go to the ASTM web site.

What's the difference between a self-tapping screw and a self-drilling screw?

Technically, both screw types are "tapping" screws because both "tap" their own mating internal thread when driven into preformed holes. "Self-tapping" screws require that a pilot hole be pre-drilled through the panel and steel support member prior to screw installation. "Self-drilling" tapping screws have a drill point on the tip that allows the screw to drill, tap and fasten the panel to the steel support member in one operation. We also offer a sharp-point Woodtite screw that will pierce through the panel and fasten into a wood support member.
