We started out in 1949 with one goal in mind...to create a line of industrial heat processing equipment our customers could believe in.
Today, while much at Grieve has changed, our commitment to that goal is steadfast.

How do Grieve ovens perform in the most difficult test...the rough and tumble of the real world? Extremely well! Each unit is built to withstand years of constant operation.

Nonetheless, if some problem happens to arise, you'll be pleased to know that Grieve has always maintained complete customer and job information on every unit we've ever built. We never retire a job file, so you know we'll always have the facts on hand should you need a replacement part.

Most important, are the people of Grieve. Our office staff, engineers, manufacturing and shipping personnel are all dedicated to your continued satisfaction.

Ovens and furnaces for which there simply are no equals...Grieve.

Grieve Quality begins with the engineer's very first layout. The highly sophisticated CAD equipment shown here translates thoughts into form, form into function. From this stage, it's on to manufacturing, where Grieve quality continues to take shape.

Testing... Grieve's Assurance of Quality Performance

More about quality

The testing of a Grieve oven or furnace is done with the same care and attention to detail as the design and manufacturing stages. Without exhaustive testing, we would, in effect, be asking our customers to do the testing for us. That’s not the way we do things at Grieve. No Grieve product gets its nameplate until it passes our rigorous test procedure. Our family name is on the door…anything less than the best won’t do.

 

Finishing & Inspection...
Our Final Touch of Quality

More about the final touch

The Grieve oven or furnace you’re about to receive at your factory has been fully performance tested. Now, our finishers take over to complete the last few steps in the manufacture of a Grieve product. From complete paint coverage to gasket fit, door hinge alignment, wire bundling neatness, shelf and accessory item counting, over 100 aspects of a Grieve product are carefully checked by a member of our company’s management before a unit is crated for shipment.
