Our Services

bi-directional stainless steel chute

Our custom fabrication shop offers a range of services to an array of industries. From replacement parts to custom products, our services fit your every need. Our areas of expertise include:

Design & Fabrication
Let us handle your custom fabrication project for industrial & commercial use. We can design, cut, bend and assemble your parts and pieces to your specification.

Engineering
We can design and create virtually anything that you can think of. Give us your CAD designs or we can design it for you. We cater to all of your mechanical and structural needs.

Welding
We can create light and heavy weldments in aluminum, steel & stainless steel. Our MIG and TIG welders are among the best in the industry.

– Gas Metal Arc Welding or GMAW (otherwise known as MIG Welding or MAG Welding) is the most commonly used welding process in the industry; due to it’s ease of adaptation, speed, and versatility.

– Gas Tungsten Arc Welding or GTAW (otherwise known as TIG Welding) the most common use for TIG Welding is for welding thin sections of stainless steel. It is also used to weld copper alloys, aluminum, and magnesium.

Steel Fabrication
We specialize in shearing, sawing, rolling, press break work, punch press work
& general machining

Waterjet Cutting
Our waterjet cutter can cut virtually any material! Waterjet Cutting (also known as Water Jet Cutting) is a process by which the machine cuts through a material or substance using using a high-pressure stream of water. Waterjet Cutting is the preferred method to avoid melting and burning of surfaces.

We have the ability to machine intricate parts out of almost any material, such as:

Hot Rolled Plate Stainless Steel Tool Steel Aluminum	Titanium Copper Tungsten Glass	Rubber Ceramics Lexan Brass
ADVANTAGES OF WATERJET CUTTING OVER OTHER METHODS:
No heat-affected zones, allowing superior edge quality Minimal tooling and set up required for short runs, making customized jobs more cost effective Eliminates many secondary operations, drastically reducing machining costs Almost no mechanical, heat or chemical influence on the workpiece Complicated contours are easily cut Great for locating and cutting holes for secondary operation prep Minimal loss of material Varying levels of cutting surface quality available CAPABILITIES Cut material up to 4″ thick 55″ X 100″ cutting envelope Two dimensional geometrics within +/- .010 Customer CAD drawings can be retried via email We can produce CAD drawings from your blue prints

About E.T. Duval & Sons

Today we are in the fourth generation of our family-owned business. It all started in 1932 when Emery Duval
opened a small fabrication shop out of his garage, working primarily for Leominster area businesses.

Emery’s son, Ronald F. Duval, inherited the business in

Founder: Emery T. Duval 1889-1945

1945. The shop remained in the garage for several more years until it became too small to handle the growing business.

Prospects grew to other industries across a wider geography, making expansion of the shop inevitable. A full-service shop facility was built just across the street from the garage to meet customer needs.

Ronald’s brother, Francis, joined the family business in 1950. The Duval brothers then transformed their father’s small home-grown business into a professional metal fabrication company.

We now serve the Greater New England area from our state of the art fabrication shop, designing for your needs with the latest computer software to give you the highest quality products from start to finish.
