Our welding range is from .010″ thick material to 6.00″ thick. Tig-weld, Mig weld, Torch/brazing, and Stick welding are all used when needed.

We have the equipment and experience to weld the following materials.



  • (ASTM) A36 Most common like AISI 1018, it can be hot rolled or cold drawn but is typically hot rolled. Fabrication processes such as welding, forging, drilling, machining, cold drawing, and heat treating are ideal. Without a protective coating, this will rust.
  • AISI 1040 carbon steel has high carbon content and can be hardened by heat treatment followed by quenching and tempering to achieve 150 to 250 ksi tensile strength. Without a protective coating, this will rust.


Most common in HVAC and places where low cost is the most important. No protective coating is needed.

Stainless Steel Fabrication

Quality Stainless Steel Fabrication Services in NH

When your job requires a sturdier, stronger solution, stainless steel is three times heavier than aluminum, which means it’s stronger as well. Because it is such a strong material, it requires a reasonably extensive fabrication process and specialized techniques.

The benefit of using stainless steel for your next fabrication project is that it is less likely than aluminum to corrode and can withstand temperatures higher than 400 degrees. If the project does not require a lightweight material, stainless steel is usually the best option.

Our fabrication experts are committed to quality by using our proven fabrication techniques, along with choosing the proper materials for the job. Check out some of our most common materials here.

Some of the grades of stainless steel we use are:


The most common grade; the classic 18/8 stainless steel. Also referred to as “A2” under the International Organization for Standardization ISO 3506.

304 #4 Polish material

Same as 304 only available in sheets and ships with a protective coating.


We recommend for applications in all high-temperature environments where scaling and corrosion resistance, as well as high-temperature strength and good creep resistance, are required.


The second most common grade (after 304); Also known as “marine grade” stainless steel due to its increased resistance to chloride corrosion compared to type 304. We recommend for food and surgical stainless steel uses; Also referred to as “A4” under the International Organization for Standardization ISO 3506.



  • Formable but not suitable for machining, unlike 6061-T6. This material is softer and more pliable then 6061-T6. When machining the end mills, fill up with chips of material more quickly. Typical applications include marine, aircraft, architecture, general sheet metal work, heat exchangers, fuel lines and tanks, flooring panels, streetlights, appliances, rivets, and wire.
  • The exceptional corrosion resistance of 5052 alloy against seawater and salt spray makes it a primary candidate for the failure-sensitive large marine structures, like tanks. No protective coating is needed. However, we do recommend chromate or anodize.


  • NOT Formable but great for machining, unlike 5052 6061-T6 is great for machining as the chips do not stick to the end mills. When forming the material tends to show stress cracks and can even split at angles of 90* or more if a large radius is not used. No protective coating is needed. However, we do recommend chromate or anodize.
