HK Testing Process

You are what you build. So build with the best.

Help buildings withstand Mother Nature, start with the smallest, most durable building blocks. The HK Ties testing process is extremely rigorous, ensuring only the most superior products thrive.

Tests passed:

  • Tensile
  • Shear
  • Long-term alkaline resistance
  • Concrete pull-out
  • Fire resistance
  • Cyclic fatigue
  • Finite Element Analysis (FEA) modeling


Much of this testing was conducted at Owens Corning’s 500 acres Science & Technology Center in Granville, OH. Additional testing has since been replicated at other building-code certified testing facilities.

See it and believe it.

Not only do we believe in our company and products, we believe in being open and transparent with our clients. Brand trust just got easier. Discover the strength of HK Composite products below.
