Build faster, build better:

building technology by Hardman-De

kaskaHardman’s unique molded steel reinforcement couplers and portable mechanical pressing system is a better way to build with monolithic reinforced concrete that offers a dramatic reduction in frame and building construction time, materials, and labor costs compared to other methods of rebar splicing and connection.

  • One set of equipment replaces 10 welders
  • On-site training provided - no specialized or craft workers required
  • Install up to 100 rebar joints in an 8-hour shift
  • Increase the reliability and structural strength of your building
  • Increase construction speed - finish faster, save time and money
  • Reduce environmental impact

We have been producing our molded steel couplers since 2008, in a full range of sizes. All couplers meet ISO 15835 international standards.

What we offer?
