Miter Cutting

Miter cutting creates a joint by cutting two pieces at an angle and fitting them together. The cut is made at a precise angle. Penn Stainless Products can miter cut ornamental tubing to your specifications. Please contact a sales representative for more information.

Polishing

Positive Material Identification (PMI)

In some cases, it may be necessary to complete additional positive material identification testing. Penn Stainless Products can complete this testing in house or we can work with an independent laboratory to complete the testing. Please contact us for specific requirements.

UT Testing

Ultrasonic Testing (UT) utilizes sound energy at high frequencies, in order to provide examinations and measurements of the stainless steel product. This aids in flaw detection/evaluation, dimensional measurements, etc.
