Sheetmetal & Fabrication



Detailed Sheetmetal work

C-Mac Sheet Metal, a large structural steel fabrication and precision detail sheet metal fabrication shop in Sydney, started in a garage more   than 47 years ago. The founder was able to fabricate stainless steel exhaust manifolds for inboard ski boats, which were something very special and hard to obtain at that time.

To this day, with a comprehensive range of computerised equipment and   machinery to assist skilled tradesmen to fold, roll, shape, weld and finish products and projects, our detailed sheetmetal fabrication workshop is able to provide "innovative sheet metal solutions" by manufacturing items, products and equipment that customers have trouble sourcing or getting designed and manufactured.

Welding & Soldering

Mig Welding

Welding involves the union between two pieces of metal by melting them together.

Soldering involves melting a lower-melting-point   material (intermediate metal like tin and lead solder, or silver solder   or brazing types) between the workpieces to form a bond between them,   without melting the workpieces.

Brazing is similar to soldering, except the temperatures used to melt the filler metal is higher.

Whether it is a small repair or a large fabrication, C-Mac in Sydney   provides quality welding & soldering service to solve your problems.   Welding and Soldering Services are in- house and on site:

  1. MIG: Metal Inert Gas or MMAW Manual Metal Arc Welding
  2. TIG: Tungsten Inert Gas or GTAW Gas Tungsten Arc Welding
  3. Stick: or SMAW Shielded Metal Arc Welding
  4. Spot
  5. Soldering: Soft Soldering and Siliver Soldering
  6. Brazing

Metal Bending

Bending metal in CNC brake press

Metal Bending, which gives the ability to produce tight radius bends on sheetmetal with no wrinkles or deformation, is a manufacturing process that   produces a V-shape, U-shape, or channel shape along a straight axis in ductile materials most commonly known as sheet metal.

Sydney based C-Mac Industries specialises in C.N.C Metal Bending as well as manual metal bending & rolling. We cater from volume   production runs down to the most complex shape, in small batch quantities with controlled accuracy and precision.

Sheet Metal Cutting

C-Mac Sheet Metal Fabrication is Sydney based and has on site a computerised plasma and profile cutting service enabling a vast array of shapes and sizes to be cut from plate or sheet metal.

Sheet metal cutting is a metalworking process that uses various machines or hand tools to create shapes and holes in a metal sheet or plate to create a metal profile.

With a wide range of cutting equipment readily available on site, it makes cutting a wide range of steel and metal for customers a easy to achieve process.

C-Mac can provide Quality Sheet Metal Cutting Services which include Manual Plasma Cutting, High Definition (HD) CNC Plasma Cutting, Oxy Cutting, Saw Cutting, Profile cutting, Bandsawing, Guillotining services and Cropping from merchant bar (flats, rounds, squares, etc), RHS and SHS to pipe, angle, plate & sheet and structural beams and builders' steel (See Photo Gallery)

Profile Cutting

Profile cutting is a process that is used to cut steel and other metals using either a hand held plasma or oxy/acetylene torch or CNC controlled equivalents.

Saw Cutting

A tool or piece of equipment used for cutting, typically a thin blade of metal with a series of sharp teeth. e.g. recipricating saw, band saw, hole saw or hacksaw.


Using a blade it is forced (using hydraulics) through the steel sheering off a section. Idealy used for cutting angle and flat bar without creating heat or sparkes.


Guillotining is the process of taking a sheet of steel and cutting it into a smaller custom sized blank to any required dimension.

Oxy Cutting

In Oxy Cutting, a torch is used to heat metal to its melting point temperature. A stream of oxygen is then trained on the metal, burning it into a metal oxide that flows out of the kerf area as slag. Nick named a "Gas Axe".

Manual Plasma Cutting

Plasma cutting (plasma arc cutting) is a melting process in which a jet of ionised gas at temperatures above 20,000°C is used to melt and expel molten material from the cut. It is the human hand that guides a manual plasma cutting torch that is responsible for the roughness sometimes seen in plasma cut pieces. Guides and templates can be used to minimise this roughness.

High Definition (HD) CNC Plasma Cutting

High Definition CNC plasma cutting systems use computers on machines to create the shapes to be cut and control the cutting machine movement and gases. The resulting shapes are smoother and more complex and accurate than would be possible with a hand plasma torch, and can include intricate curves, inside cuts, and sharp corners.

HD CNC plasma cutting also provides near laser quality cutting at a fraction of the time and effort usually required by traditional oxy cutting. It is designed for high speed, accuracy and large capacity cutting of material.
