Process and materials required for Metal fabrication

Posted by Jessica Beak on June 29th, 2017

What is metal fabrication?

Metal fabrication is the process of making machines or any structural designs from different metallic raw materials. The architectural metal fabricators NY are also known as fab shops. The main job of such fabricators is to manufacture equipment like stairs, railings etc. They design such structures by welding a metal.

The process of fabrication starts with planning stage. The professional orders suitable materials and designs CNC machines for the work. Specialized projects are also out sourced sometimes. The process of fabrication involves many techniques like welding, punching, forging, brazing, casting, spinning, lathing, grinding, broaching, honing, milling and drawing. Many projects also include hydraulics and electrical facilities as well.

Materials required for fabrication

There are many basic raw materials used in the process of metal fabrication. Different techniques require different raw materials. Here is a list of such raw materials used by architectural metal fabricators NY.

• Materials required in Casting

1. Silver
2. Stainless steel
3. Gold
4. Steel
5. Copper
6. Magnesium
7. Iron
8. Aluminum
   

• Basic fabricating items

1. Plate Metal
2. Welding wire
3. Fittings
4. Formed and expanded metal
5. Castings
6.  Sectional metal
7. Flat metal
8. Hardware

• Hardware

1. Wires
2. Corners
3. Wires
4. Chains
5. Handles
6. Latches
7. Locks
8. Keys

• Types of metals

1. Hollow structural section (HSS): This type of metal is available in different shapes like square, circular etc. It has a hollow piping in it.
2. Bar: Bars have a flat shape, molded into long rectangular metal.
3. Rod: A long metal in form of square or circle is called a rod.
4. Z-shape: This type of metal is structures in form of alphabet “Z’, and has lots of angles.

Procedure of fabrication

There are three steps involved in making of metal structures. They are as follows:

• Cutting

The process starts by cutting the required materials with CNC machines under control of engineers. Cutting is done through different ways like chiseling, sawing torching, lasers, shearing etc.

• Bending

The next step in fabrication is bending the structure. Bending is done via hammering or press braking. Modern custom stair interior fabricators NY use the press brakes technique. The metal is air bended into the required form. The CNC press brakes are the most efficient in nature.

• Assembling

The last step in the process is joining all the elements together. The elements are assembled together through welding, riveting, using adhesives, using thread fasteners etc. The materials required for assembling are welding wires, fasteners and flux.

The other types of metalwork include process like metal stamping, casting, forging, machining etc.
