Most Common Frame Finishes for Tensile Fabric Structures

Tensile Fabric Structures Frame FinishesTensile fabric structures use a combination of high-strength metal framing and tensioned membranes to create functional and beautiful pieces of architecture.  To achieve the desired look, designers choose from a variety of frame finishes, including these most common options.

Polyester Powder Coat Finish

The polyester powder coat finish is the most economical option and has low VOCs (volatile organic compounds).  With no liquid being used for the application of this finish, it’s a simpler process for achieving a consistent thickness.  The powder finish is applied with an electrostatic gun, dries fast, and cures at 390o F.

At Eide, we follow these specifications (and many more) for quality control when using polyester powder coat finishes:

  • Commercial blast clean surface in accordance to SSPC-SP 10.
  • Primer and polyester powder coat paint applied to a minimum of 3 mils thick.
  • Color options: Selected from standard RAL numbers.
  • Premium Options Available: Metallic Colors and Wood Grain.

Three-Part Epoxy Paint Finish

Three-part epoxy paint is more expensive than powder coating but offers better protection against corrosive environments.  With no need for an oven to cure the finish, there are no size restrictions for projects using this option and it can be applied in the field as needed.

At Eide, we follow these specifications (and many more) for quality control when using three-part epoxy paint finishes:

  • Commercial blast clean surface in accordance to SSPC-SP 10.
  • Primer Material properties – (1) coat of PPG/Ameron’s Dimecoat 9 at 2.5-4.0 mils MDFT.
  • Paint Material properties – (1) coat of PPG/Ameron’s Amerlock 2 at 3.0-7.0 mil MDFT per coat.
  • Paint Material properties – (1) coat of PPG/Ameron’s PSX 700 at 3.0-7.0 mil MDFT per coat.
  • Minimum thickness – 8.5-18 mils TDFT.
  • Color option: As selected from manufacturer’s available stock colors.
  • 10-year warranty for gloss and color retention.

Hot-Dip Galvanizing Finish

Hot-dip galvanizing coats steel frames with a layer of molten zinc, inside and out, to provide a highly abrasion-resistant and corrosion-resistant finish.  While this basic concept has been available for more than 150 years, new technologies and creative chemistry has made this durable finish available for a multitude of projects, including for tensile fabric structures.  With at least 1” holes at both ends for drainage, the frame elements are dipped in a bath of molten zinc that is kept at a temperature of approximately 840o F.

At Eide, we follow these specifications (and many more) for quality control when using hot-dip galvanizing finishes:

  • Comply with either ASTM A 123/A 123M or ASTM A 153/A 153M standards.
  • Commercial blast clean surface so it’s free from all dirt, debris, oil, or grease.
  • Fill vent and drain holes that are exposed in the finished work (unless indicated to remain as weep holes) by plugging with zinc solder and filing off smooth.

When creating tensile fabric structures, designers have a wide variety of options, including the style and shape of the structure and the type of membrane, in order to create unique and iconic structures.  Explore the benefits of tensile fabric structures for your next project.
