Custom Metal Fabrication
Metal fabrication is the creation of metal structures
by cutting, bending, welding and assembling processes.
It is a value-added process involving the creation of
machines, parts, and structures from various raw
materials. Metal fabrication usually starts with
drawings with precise dimensions and specifications.
Typical projects include loose parts, instrument
enclosures, structural frames for buildings and heavy
equipment, and stairs and hand railings, etc..
Process of Metal Fabrication
Cutting
Cutting is done by sawing, shearing, or chiseling (all
with manual and powered variants); torching with
handheld torches (such as oxy-fuel torches or plasma
torches); and via numerical control (CNC) cutters
(using a laser, mill bits, torch, or water jet). Here
several tools like notches, punches, lasers, plasmas,
shears and saws are used.
Bending
Bending is done via press brakes, tube
benders and similar tools. Modern metal fabricators use
press brakes to coin or air-bend metal sheet into form.
CNC-controlled backgauges use hard stops to position
cut parts to place bend lines in specific positions.
Assembling
Assembly (joining of pieces) is done by welding,
binding with adhesives, riveting, threaded fasteners,
or further bending in the form of crimped seams.
Structural steel and sheet metal are the usual
materials for fabrication; welding wire, flux and/or
fasteners are used to join the cut pieces.
Coating
Surface finishing is an industrial processes that
alter the surface of a manufactured item to achieve a
certain property. Finishing processes may be employed
to: improve appearance, corrosion resistance, tarnish
resistance, chemical resistance, hardness, remove
burrs and other surface flaws, and control the
surface friction.
SVEIFAB has the ability to apply any required coating in sets of our heated coatings facilities which meets government environmental requirements. The fabricated steel is cleaned with a spraying line first to remove dirt, grease, mill scale and rust. Coatings vary from powder coating, sandblasting and painting line which is self-owned, and galvanization is performed off site using local businesses.

Application of Custom Metal Fabrication
Metal fabrication is the process of turning
raw metals into pre-made shapes for assembly use.
For example, Electrical enclosures and any type of
metal enclosures require sheet metal fabrication.
Look around you. Many people never notice it, but many
of the products and components we take for granted have
some aspect of precision sheet metal fabrication. From
desk bracket to construction steel form, and all types
of finished products and parts in between start out as
sheet metal or heavy steel. The sheet metal fabricator
machines punch, cut, drill, bend, shape and assembly
metal sheet into an endless number of forms.
Fabricators use their experience and mastery of a variety of processes, including welding, heat treating, adhesive joining, brazing and soldering, stamping and rolling, tumbling, buffing, polishing and honing. Fabricators take the customers’ desired material, the rate of production, the desired geometry and other physical requirements of the part to create an optimized, cost-efficient manufacturing process. Companies across a broad spectrum of industries, products and service offerings require the expertise and services of companies that specialize in sheet metal fabrication. For SVEI, the sheet metal processing services we provide cover the following industries:

Although commercial and industrial companies typically
use metal fabrication services, they purchase
customized metal parts for plants, warehouses, office
buildings and other spaces. Some residential homeowners
also have a need for customized metal fabrication
services.
Cost of Custom Metal Fabrication
Many businesses require custom fabrication solutions for a wide variety of applications. As each product is made specifically to match your needs, it is natural to ask yourself what you will pay for these services. This number will be based on many factors:
Dimension
The dimension of the custom metal fabrication project that you need to be completed will have a great influence on the overall cost as larger products will use more labor and materials. From small bracket to huge production equipment enclosure, cost vary widely.
Material
The metal used for custom fabrication will affect the price greatly. Metals that are commonly utilized include mild steel, aluminum alloy and stainless steel, and heavy steel. However, depending on the type of project other metals like brass and copper may be used as well.
Process
The processes which will be used to design your custom fabricated metal work will influence the price too. Some commonly used processes are punching, metal cutting, bending and welding. The total cost will be influenced too by the number of processes that will have to be carried out. Their complexity will play a role in the total cost of the custom fabrication. The more expertise and experience required, the more expensive the process will be.
