Find the full liquid head limit of the form
The full liquid head limit can be determined using the following graph below. The wall thickness is a function of the height and the diameter of the concrete form. For example, if the desired form has a diameter of 40″ and a height of 8 ft. the ideal wall thickness will be 5/16″ (7.5 mm).

Column Forms Brochure

PDF version

  • Superchute® Concrete Forms are all made of High Molecular Weight Polyethylene Plastic.
  • HMWPE is resistant to abrasion, chemicals and cold weather
  • Clients in Alaska and other cold climates appreciate its low temperature impact resistance of -100 ºC (-156 ºF)
  • In hot weather the plastic will become a little softer
  • Bright yellow plastic (safety-minded color) shows off your company name plate
  • Many thicknesses available
  • UV treated

  • Unique clasp consists of a pair of 95° aluminum angles riveted to the form wall
  • 95° angle clasp helps the form maintain a continuous round shape
  • Aluminum clasp is quickly closed using the supplied speed bolts & nuts for a tight seal

Button Head Rivet (original design)
The 1/2″ dia. button head creates 2 vertical bands of very shallow dimpled imprints on the concrete surface.

Countersunk Flat Head Rivet

  • Use this rivet style when you must have a smooth concrete surface finish
  • Since the rivets are countersunk 1/16″ of the plastic wall is lost slightly reducing the clasp strength
