Expertise and Quality with Any Material Grade

Over the years, our skilled and dedicated staff of Engineering /Technical Professionals and Metal Finishing Experts, who take pride in their work and have made a commitment to excellence, have developed processes capable of producing products from most material grade, including:

Stainless Steel Bars
  • Low, Medium & High Carbon & Alloy Steels
  • Stainless Steels
  • Nickel Alloys
  • Aluminum
  • Copper
  • Brass
  • Teflon Plastics

Product liability legislation is on the rise and the manufacture can no longer sidestep their responsibility for considering the effects of poor product performance. Our products have performed successfully in service environments the must meet the most extreme requirements such as; Ductility, Toughness, Shear Strength, Fatigue Strength, Hardness and/or Corrosion. Today's manufacturer of high performance products must be knowledgeable on the origins of products failures, such as Stress Corrosion, Hydrogen Embrittlement, Stress Embrittlement, Stress Corrosion Cracking, and the effectiveness of various countermeasures. For example, all of our heat treated and plated products are manufactured to tolerances that will facilitate thread gage inspection requirements, torque-tension relationships, preventing assembly and interference between mating parts, particularly threads, slots, grooves and recesses . Simply stated, our products are capable of performing, combating failures and providing solutions for your toughest service requirements and environments.
