KDM Galvanized Sheet Metal Fabrication Advantages

The fabrication of galvanized sheet metal is among the most popular fabrication around the world. This is due to their numerous advantages, which include:

Long-Term Investment – Because of its long-term investment, galvanization of metal parts is a great option for many businesses. In normal environments, the galvanized sheet metal can indeed last around 50 years, unlike the other metal that is applied with a protective coating. In coastal or severe urban environments, they can also survive for 20 to 25 years.

Less Expensive – Galvanization of sheet metal does not require as much labor. So, they are one of the least expensive options.

Most Durable Protective Coating – Hot-dip galvanization is a process that makes the sheet metal extremely durable and resistant to rust, corrosion substances, weather conditions, and scratches. This process is done by fully dipping the metal into the molten zinc and all parts of the metal such as recesses and sharp corners will be fully coated, unlike other metal that are not galvanized. The zinc also acts as a sacrificial anode. This means that even if the coating is scratched, there is a remaining zinc that will protect the affected metal.

KDM Galvanized Sheet Metal Processes

Galvanizing sheet metal parts can be done in a variety of ways. But, the most popular methods are hot-dip galvanizing and electro-galvanizing methods.

Hot-Dip Galvanization Process – Hot-dip galvanization is a process that involves completely immersing the metal in high-quality molten zinc that has a minimum zinc content of about 99.95%. And the zinc protects the metal from scratches, oxidation, corrosive substances, moisture, weathering, and rust. Also, this process can coat all areas of the metal such as difficult-to-reach areas like corners, recesses, etc.

Electro-Galvanization Process – The coating created in the electro-galvanizing process is typically not as thick as that created for the hot-dip galvanization process. In this process, the coating is thick, uniform, and adheres well. The coating in the electro-galvanization can be made from either pure zinc, zinc-nickel, or zinc-iron. In this kind of process, electroplating is used for coating the metal with a layer of zinc. Moreover, it has no zinc crystals on the surface, unlike the ones found on the hot-dip galvanized sheet metal. Some of the advantages of this process are that it could be performed in cold temperatures without affecting the metal’s mechanical properties.

  • CNC Punch presses and laser are used to cut holes into Sheet metal during the process of manufacturing.
  • Water jet cutting machine has the ability to cut metal materials using high pressure jet of water or a mixture of water and abrasive substance that can cut metal.

This tool is used when cutting various parts of a machine.

It’s the best method when handling metals that are sensitive to high temperatures.

You can learn more about laser cutting sheet metal.

Bending Galvanized Sheet Metal

This process involves bending the metal surface to a certain shape at an angle.

The process is complex.

It requires high-tech equipment such as: Press brakes, folding machines, panel benders

Welding Galvanized Sheet Metal

This process involves craft work.

Two metal parts are joined in this process.

Welders can use welding to turn a concept into a metallic reality.

There are two methods of welding.

Fusion welding which is heating metal parts and using fillers to fuse them into joints.

Solid state welding which is same as fusion but doesn’t use additives.

It is a series different welding techniques producing fusion of temperatures below the melting point of the metals being joined.

The main processes of welding are

  • MIG (Gas Metal Arc Welding)-

It is preferred for thin stock and sheet metal welds.

It requires electricity for heat production, electrode for filling the joint and shielding gas for protecting the weld from air.

In this method, a wire moves continously at the heated head of a welder.

The wire melts and drips onto the metal piece to be joined to another

  • TIG(Tungsten Inert Gas Welding)-

It’s the most refined form of welding.

An electric arc goes heats between Tungsten electrodes (non-consumable electrode) and a metal thus joining the metals. .

  • Robotic Welding

Robotic Welding

This is which uses a robot to join metal parts.

It is an automated process thus increases accuracy.

It is safe and does not take a lot of time to complete a project.

To use this mode of welding you require highly trained and certified personnel.

There is a tool in the robotic arm heats to melt metal and join the various metal pieces together.

Robots can perform other types of welding such as TIG and MIG.

  • Laser welding

It is also used for joining different metals

When welding using laser welding machine, the fabricators role is limited to controlling a robot.

The laser welding head moves around the work piece in an enclosure that is made to hindered release of laser light.

The laser machine has the ability of minimizing heat during welding

They are two types: hand held laser welding machine and automatic laser welding machine

Hardware Insertion

This is a process of using compression force to insert fasteners into a metal surface.

The hardware insertion include studs, standoffs, clinch hardware and nuts.

They can insert upto four fasteners at one go.

Grinding & Graining

Metal grinding is a process of finishing rough edge, cleaning up welds, belt sanding to put nice grained finish.

Metal grinding

The process can be done manually using file or grinding machine.

Graining as a process of galvanized metal fabrication involves using coated abrasives to soften the surface.

You can work with the grains longitudinal or transverse.

Graining is used in industries such as aerospace, telecommunications and medical services.

Electro-galvanized Sheet Metal Vs. Hot Dip Galvanized Sheet Metal

Electrogalvanized is a process where zinc is electro plated on a sheet metal in order to shield it from rusting and corrosion.

While dip hot galvanizing involves submerging a sheet metal in hot molten zinc for the same reason of protecting it from rusting.

electro galvanized sheet metal

electro galvanized sheet metal

Hot Dip galvanizing provides a thick resistance which lasts for a long period.

Electro galvanizing provides a thin layer of protection which means the protection against corrosion is for afew months.can be used in areas with limited exposure

Electro galvanized metal when applied or exposed to harsh environments, they corrode very fast.

Hot dip galvanized sheet can withstand extreme environment due to the thick layer of zinc protection.

Hot Dip galvanization has dull and rough finish.tThey are not recommended for aesthetic applications.

Electro-galvanized metal are smooth and bright and excellent for aesthetic applications

Hot Dip galvanizing process Involve: pre- plated parts, decreasing, water washing,, pickling, water washing,squeezing, water solvent, drying and packing.

Hot dip galvanized sheet metal

hot dip galvanized sheet metal

Electro galvanized process involves: pre-plated parts, decreasing, erosion, polishing, galvaning, hydrogen removal, dyeing.

Electrogalvanized metals are suitable for small parts while hot dip galvanized mate can be used for all sizes.

Applications Of Galvanized Sheet Metal Fabricated Parts

Galvanized Sheet metals Fabricated Parts are applicable in the following ways:

  1. Electrical appliances such as making computer casings and precision instruments. Zinc coating is excellent for these appliances because it resists rust and moisture.
  2. Construction materials. Sheet metal is majorly used for construction projects for various purposes.

These include; making balconies, frames, canopies, Awnings, Ductwork, Hand rails, staircases and fences and ladders.

I) Galvanized Sheet Metal is used in making pipes for cold water plumbing. Galvanized plumbing pipes lasts long.

II) Transport industry. Galvanized Sheet Metal are composed in aircrafts and cars to make; oil pans, fenders, hoods, parking brakes , roofing, spring Housings and seats

III) Children play equipment such as swing sets, jungle gyms and bicycle racks.

IV) Telecommunications industry- galvanized sheet metal is used in this industry for phone wiring and equipment boxes.

V) Nails bolts and nut manufacturing.

VI) Tanks, boiler and ship container manufacturing.

Surface Finishes For Galvanized Sheet Metal Parts.

The final appearance and finish provides important information which reveal any error that happened during the process of Galvanization.

Some of the surface Finishes of galvanized sheet metals.

Grinding off zinc drips form the sheet surface to create a smooth surface.

Organic finishes: These are organic coatings that act as barriers between the metal and corrosives in the environment.

When applied to metallic surface they provide protection against harsh weather conditions, and provide aesthetic appearance.

These include painting and porcelain enameling

  • Paint coating is used to prevent further corrosion and rusting of galvanized sheet metals.

However long the galvanized sheet metals take eventually they will rust.

Painting slows the process of corrosion.

Painting is also used for aesthetic reasons, they also provide texture to the finished product.

  • Powder coating– This is also known as dry coating.


Powder coating

Dry powder is applied through electrostatic process.

The finishes are high quality finishes in terms and function.

There are two types of powder coating; Thermoplastic and thermoset.

This gives rise to a high quality coating on steel which produces a matte gray finish.

Metallic finishing: This is a process where some metal coating is placed on the surface of a metallic part.

  • Electroplating ‘-this is a process of using electric current to coat metals.

The plating metal is moved to another conductive metal through electroplating.

The electric current deposits some amount of metal on the cathode (the bar holding the work to be plated).

Uniformity of the surface is maintained when the anode dissolves.

  • Sherardizing– This is a finishing process where small parts are tumbled in zinc dust. This is done at a temperature below zinc melting point.

A thin coating that is mettellurgically bonded to the metal part is formed.

  • Galvannealing– this is a process where hot Dip galvanization and annealing are combined.

First the metal part has gone through immersion in hot molten zinc.

Next the excess zinc is removed using air knives.

From there it is heated in an annealing furnace for some seconds.

This leads into the formation of zinc – iron alloy on the surface on the metal part.
