Pre-Treatment

All of our metals undergo a pre-treatment prior to coating finishes, in order to prepare the surface and improve the quality of finishing coats. This is especially common in applications requiring plating or powder coating.   

Mill Finishes

If not stated, our team will determine the right finishing process for your project during initial contract review. Our choice of finishes include:

Pickled and Oiled Mild Steel

Used in applications requiring a high level of surface cleanliness, pickling and oiling removes mill scale and other contaminants. Pickling is undertaken to clean the workpiece surface prior to oiling, which helps protect the clean surface from oxidation. 

Hot Rolled Steel

This refers to steel processed above its recrystallisation temperature, resulting in a product that is easier to form and work with. It is suitable across steels and steel grades, oftentimes required because of the product and material specifications.

2B (Stainless Steels)

The 2B finish is a smooth, grey metal finish with reduced shine, achieved on a processing mill. Applications for 2B are most commonly stainless steel where the appearance of the metal is insignificant, however aluminium and brass can also achieve a 2B finish.

Dull Polished (Stainless Steel, Aluminium, Brass)

A dull polished finish is more aesthetic than 2B but is not as bright as a mirror polish. The dull polish is used on stainless steel, aluminium and brass products designed for decorative applications.

Mirror Polished (Stainless Steel, Aluminium, Brass, Copper)

A mirror polish is a highly reflective, bright shine finish. It is used on aesthetic products designed to be seen, such as furniture, shop fitting components, automotive parts and more.








    Secondary Operation Finishes

    Powder Coating

    Powder coating is a common finish that provides a hardened, durable coat on surfaces. It is created by spraying dry powder onto a component, which is then cured. Subcon Laser’s powder coating service is available in a wide range of colours to meet design requirements.

    Electro Coating (E-Coat)

    Electro coating is a painting process, depositing electrically charged wet paint particles onto the part in a coating bath, before being cured to harden the coating.

    Electro coating requires a conductive part material in order to be successful.

    Galvanising

    Subcon Laser provides galvanisation, coating parts with a layer of zinc to protect them from corrosion. The component is immersed in a bath of molten zinc, and through a metallurgical reaction, a bonded layer of zinc is formed on its surface.

    Plating

    Subcon Laser utilises a trivalent passivate following zinc plating. Trivalent passivation is more environmentally friendly than outdated alternatives while maintaining the same levels of protection. A highly efficient method of coating, and available in clear (bright sheen) and black. Heavyweight Zinc Trivalent is further available.

    Anodising

    For increased corrosion protection, as well as improved aesthetic qualities to metal surfaces, we offer anodising. Anodising is an electrochemical process that forms a protective oxide layer on the surface of metals, commonly aluminium.

    Electro Polishing

    Electro polishing removes material from the surface of the component in order to clean and smooth it, as well as producing a bright polished finish and improving the corrosion resistance of the metal.

    Don't take our word for it...

    We have been using Subcon Laser for several years now and can’t recommend them highly enough! They are really helpful and friendly, they deliver on their service promises, and their quality and turnaround times are great.

    Richard, General Manager - Production Company

    It gives me great pleasure to be able to be involved in creating a testimonial for Subcon Laser for the outstanding service they have given me over the past 10 years. The main point of contact for me would be Tom Mongan, who is the general manager at the organisation and whom as I understand has been at the company for over 20 years.

    Buyer - Pressing Company

    As one of the longest established laser cutting companies within the UK with a high staff retention ratio, it comes as no surprise that the skill, knowledge and technical ability of their staff is really what sets them apart from their peers. One also has to mention their investment strategy in the very latest laser technology because this also sets them apart from a lot of companies as they are able to compete at every level.
