Today we make a broad range of reliable products, from bolts and beams, to channels and trusses, to resin and rebar. We’re proud to make products that make mining and tunneling safer and more efficient.

A Single Source Provider

Our network of affiliates includes engineering services, resin manufacturing, rolled-steel and drill-steel manufacturing, carbide drill bits, custom steel fabrication, chemical roof support and sealing products, and even includes staffing solutions and our own trucking company. This ability to provide a complete range of complementary products and services ensures quality, efficiency and availability, resulting in reduced costs, reduced lead times and increased customer satisfaction.

JENNMAR continues to grow, but our focus will always be on the customer. We feel it is essential to develop a close working relationship with every customer so we can understand their unique challenges and ensure superior customer service. Our commitment to the customer is guided by three words; Safety, Service and Innovation. It’s these words that form the foundation of our business. It’s who we are.
