CUSTOM FABRICATION

 

Occasionally, we do custom fabrication for people outside of our usual customer base. Here we have a beautiful custom fabricated stainless steel countertop done for a local couple.


This countertop was fabricated to match the couple’s other stainless steel appliances. After several hours of programming and fitting samples, we started with 14 GA #4 Brush Finish Stainless Steel also called Directional or Satin Finish. Since its invention in 1913, stainless steel has been a multitasking wonder and is the most popular finish for appliances and matching countertops. It can make a sweeping design statement and makes clean up a breeze. Also, stainless steel (unlike other countertop metals) won’t patina. Brush finish is the most common of stainless steel cosmetic finishes and is characterized by fine polishing grit lines that are uniform and directional in appearance. For this project, the finish was produced by polishing the metal with a 120-grit Walter Hand Sander.

Cutting

Blanks were cut using our Whitney plasma cutting system with Hypotherm HPR260 torch with 80″ x 20′ cutting table capable of cutting up to 1-1/4″ thick steel.

Bending

Bending was performed on our Cincinnati Press Brake with Gladwin Crowning System and JMT Durmazlar AD-S Press Brake with 120” bending length.

Welding

Finally, the welding process used was Gas Tungsten Arc Welding (GTAW), also known asTungsten Inert Gas (TIG) welding. This is an arc process that uses a non-consumable tungsten electrode to produce the weld. The weld area is protected from atmospheric contamination by an inert shielding gas (argon or helium), and a filler metal is normally used, though some welds, known as autogenous welds, do not require it. A constant-current weld power supply produces electrical energy, which is conducted across the arc through a column of highly ionized gas and metal vapors known as a plasma. TIG welding is most commonly used to weld thin sections of stainless steel and non-ferrous metals such as aluminum, magnesium, and copper alloys. The process grants the operator greater control over the weld than competing processes such as shielded metal arc welding and gas metal arc welding, allowing for stronger, higher quality welds.
