Deciding on which finish to use when designing your project can be critical to the project’s success. As the final step in preparing metal products, you do not want to have to start all over again if the part cannot be used correctly. Will it be able to stand being used in its environment? Will it develop rust or corrode?
As a leading metal fabricator in Sydney, the Ogis Engineering team can help ensure your project is designed to last. Continue reading to learn how to choose the right finish for your metal fabrication project.
Reasons To Add A Finish
Applying a finish to your metal products and projects can increase overall quality in several ways:
- Increased resistance to chemicals and tarnishing
- Greater visual appeal
- Increased durability
Types Of Finishes
Stainless Steel Finishes
2B Finish is a dull industrial finish usually used where aesthetics is not the primary focus. Possible applications for 2B stainless steel finish include bakeware, chemical plant equipment, flatware, laundry and dry cleaning as well as plumbing fixtures, refrigeration and vacuum drum dryers.
No. 4 Finish
No. 4 Finish is stainless steel that has been polished with abrasive belts to give a low gloss and the best overall appearance. Also referred to as “satin” or “linished”, it is considered the main stainless-steel finish for the light fabrication industry, used for work surfaces, handrails and applications requiring good aesthetics such as kitchen equipment, storefronts and boat fittings.
No. 8 Finish
No 8. Finish is a mechanical polish by successively finer abrasives and buffers which results in a highly reflective finish. Also referred to as “mirror” finish, it is commonly used in projects such as mirrors, ornamental trim, reflectors and signage.
Electropolish provides a smoother, brighter and deformation-free metal surface that has superior corrosion resistance.
Bead Blasting is ideal for stainless steel used within food industries and for car restoration parts. It provides a dull finish which removes weld discolouration.
Powder coating is a cost-effective way to paint production items and provides a thick, hard finish that is tougher than conventional paints. This finish best suits metal substrates such as aluminium, stainless steel or steel, and is relatively quick and easy to apply.
Wet painting is the traditional way of finishing metal, involving applying liquid paint by spray, pump or pressurised vessel. It is especially good for harsh environments and produces a much thinner finish than powder coating.
Electroplating (Chrome, Nickel, Bronze and Zinc)
Electroplating is the process by which metal is deposited on a conductive surface. It is a decorative finish, some with good durable surfaces, and provides a wider range of colours. This also works well for products that cannot be heated for powder coating.
Hot Dipped Galvanising
Hot dipped galvanising is a chemical process that is used to create a protective coating in order to prevent corrosion of steel through atmospheric exposure. This is ideal in situations in which aesthetics are not a priority.
How To Choose?
Consider the following factors when choosing a finish for metal fabrication:
- Which process best suits how the product will be used?
- Does the technique fit into your timeline?
- Is the finishing method cost-effective?
- Is the finishing technique suitable for the project’s materials?
