What Is Sheet Metal Fabrication?
Sheet metal fabrication is a subtractive manufacturing process that forms parts from thin metal sheets. Engineers often choose sheet metal parts for their high precision and durability, especially for end-use applications like chassis, enclosures, and brackets. China CNC Machining Service

How Tiandiao Sheet Metal Fabrication Works
Tiandiao's metal fabrication services utilize the top sheet metal fabricators. Sheet metal
fabricators first convert CAD and drawing data into machine code. A laser cutting, waterjet,
or plasma cutting machine will then precisely remove sheet metal material. The raw material
is formed into angular bends and features using brakes, punches, and dies. If any assembly
or post-processing is required, our sheet metal manufacturers will weld, add inserts, or
finish the part.
The efficiency and high precision of metal fabrication, coupled with Tiandiao’s variety of materials, range of sheet metal fabricators, and post-processing options means you can get parts for any application. Sheet metal applications include aerospace, defense, automotive, energy, industrial, medical, dental, and consumer products.
Sheet Metal Materials Available at Tiandiao
Aluminum 6061: A heat-treatable aluminum sheet metal with medium to high strength, used for a variety of
applications including furniture, boats, and automotive.
Aluminum 5052: A lightweight, corrosion-resistant aluminum with good forming and welding characteristics; it is the most commonly used sheet metal fabrication material.
Copper 101: A highly conductive, 99.99% pure sheet metal copper often used in specialty electrical
Copper C110: A low-cost, multipurpose copper often used in electrical sheet metal applications.
Brass Copper 260 (Brass): A highly formable brass often used in high heat components and decorative home hardware.
Stainless steel 301: A high-strength stainless steel for sheet metal, used for aircraft, automotive, and
train structural components, appliances, and utensils.
Stainless steel 304: The most common stainless steel for sheet metal fabrication applications with increased corrosion resistance over 301 and industrial applications like food processing equipment, railing and trim, and more.
Stainless steel 316/316L: A stainless steel with increased corrosion resistance over 301 and 304, which makes it ideal for marine, medical, chemical, and chemical processing applications.
Steel Steel 1018 (Low Carbon): A highly formable and weldable steel due to its ductility and high heat-transferability. This material is typically cheaper than aluminum but is of lower strength and is susceptible to corrosion.
Custom Additional alloys and tempers are available upon request. We can source to your project specifications. Review more information about our materials here.

Available Sheet Metal Finishes
Standard Minimal post-processing or treatment on parts is done
Bead Blast The part surface is left with a smooth, matte appearance.
Anodize (Type II Or Type III) Type II (MIL-A-8625, Type II) creates a corrosion-resistant finish. Sheet metal parts can be anodized in different colors—clear, black, red, and gold are most common—and are usually associated with aluminum. Type III (MIL-A-8625, Type III, Class 1/2 "hardcoat") is thicker and creates a wear-resistant layer in addition to the corrosion resistance seen with Type II.
Chem Film (Chromate Conversion Coating) This sheet metal finish provides corrosion resistance and good conductivity properties. Chem film can be used as a base for paint and can leave surfaces yellow or gold. Adds very little thickness, about 0.00001”-0.00004.” Chem film will conform to MIL-DTL-5541, TYPE I/II.
Powder Coat This is a process where powdered paint is sprayed onto a part that is then baked in an oven. This creates a strong, wear- and corrosion-resistant layer that is more durable than standard painting methods. A wide variety of colors are available to create the desired aesthetic.
Electroless Nickel Plating Provides uniform nickel coating which offers protection from corrosion, oxidation, and wear on irregular surfaces. The finished part will be brighter. Thickness starts at .0001” and this finish conforms to MIL-C-26074.
Gold Plating Gold Plating provides good corrosion and tarnish resistance with excellent solderability. Default application specification is MIL-G-45204 & ASTM B488, CLASS 00, 0, OR 1 (Thickness 0.00002" - 0.00005").
Silver Plating Silver offers high solderability and electrical conductivity but is susceptible to tarnish on sheet metal parts. Conforms to AMS QQ-S-365D. Thickness is about 0.00002”- 0.0003.”
