Introduction

Are you thinking of buying stainless steel coils to meet your needs? If the answer is yes, then you might want to choose the hairline stainless steel coil.

Keep reading the article, and you will know why.

What is hairline stainless steel coils?

The decorative hairline stainless steel coil is a type of stainless steel coils. Featured with their surface finishing with the lines resembling human’s hair, they get their names of “hairline”

Compared with traditional mirror/glossy surface finishing, they remain unique and easy to recognize.

The hairline effect gets their patterns by endless grinding lines.

These grinding lines extend uniformly along with the length of the stainless steel coil.

The hairline finish is a well-defined directional finish with a long and fine taste of art.

However, its surface is matte and does not glow. Even so, it doesn’t affect its decoration.

So, it’s common to see them in our daily life.

Does Hairline stainless steel rust?

Hairline stainless steel has a visible grain that creates a matte surface. This, like any other stainless steel, can rust over time once the layer of protective surface wears off. Use mild cleaning solutions that will remove this rust without damaging the metal.

Stainless steel can contain other elements such as nickel and manganese, but chromium is the key element which makes it rust-resistant. As long as there is sufficient chromium present, the chromium oxide layer will continue to protect the stainless steel and prevent it from rusting.[1]

 How do you remove rust from hairline stainless steel?

Removal of oxidized stains and even “surface rust” can be done by using a paste made from baking soda and water or a cleaner that contains oxalic acid, such as Bar Keeper’s Friend Soft Cleanser. If using baking soda and water, use a cloth or soft bristle brush, rub the baking soda in the direction of the grain.[2]

Applications of hairline stainless steel coils

Hairline stainless steel coils offer more than just a glamorous look.

At the same time, its surface is very clean. Therefore, it helps to improve its corrosion resistance and ease of maintenance.

People are often attracted by the appearance of stainless steel.

But also, in many industries, it is a durable and practical material choice.

You can find the footprint of hairline stainless steel coils in the following applications:

  • Elevator panels
  • Escalators
  • Interior cladding
  • Building facades
  • Architectural cladding
  • Signage and interiors
  • Machinery
  • Automotive
  • Exhibition
  • Cookware for home and business use
  • Various home appliances and commercial appliances
  • And more

In fact, the widespread use of hairline stainless steel result from their benefits.

The benefits and drawbacks of hairline stainless steel coils

The benefits

The hairline brushed stainless does not reflect light.

This effect can even be better than the glossy stainless steel sheets.

For example, the colour on the hair brushed stainless steel table looks noble, but not shiny.

So, the stainless steel hairline finish provides a unique and distinct choice for designers.

For products that require very good materials, in particular, the beautiful colours and texture coatings. It will be the right choice.

Shinning is one of the advantages of your stainless steel. Therefore, it can attract people’s attention and has the characteristics of a modern style. But if we want it to be less smooth, we can use decorative stainless steel hairline.

Some might have an experience like this when busy looking for ways to clean the stainless steel items.

I don’t like stainless steel. Like many remodelers, I worry about the resale value of my house. So, I want to do it once and for all.

However, because the front and handlebars are difficult to keep clean, it is difficult to completely clean fingerprints and scratches. Then, this issue might once remain a burden to many.

Their minds change until they find hairline stainless steel.

One of the critical reasons is hairline stainless steel hides scratches and fingerprints.

As a member of the brushed stainless steel family, hairline stainless steel isn’t something new actually.

The story shared by Keith Barry on reviewed.com talked about the merit of it.

Mr Barry said, the cooktop and range his grandmother bought in 1961 still looked good after over 50 years.

According to the author, his grandma wasn’t afraid to scrub off stains. Meanwhile, she didn’t have to spend hours washing away every fingerprint with a specialized cleaner.

The drawbacks

Some people think this is more suitable for construction projects because the overall appearance is the most important factor. There can’t be any wear and tear, and many people don’t like to have too much reflection.

However, it is important to know some level of variation might happen due to the manufacturing process.

Thus, the hairline finish is less resistant to corrosion in coastal areas due to salt particles in the air.

High humidity areas, such as around swimming pools, are also not suitable for hairline stainless steel and glass exterior railings. This is because the grooves in the finish increase the risk of rusting.

Hairline stainless steel coils vs. polished stainless steel coils

1、Different concept

Hairline Stainless steel refers to the texture effect of stainless steel surface stripe, is the most common stainless steel surface processing technology, the most widely used one. The matte surface of the stainless steel plate into the brushed processing, there is a fine surface texture, but there is no concave-convex feeling.

Hairline stainless steel compares with the general 2B surface stainless steel are much better because the surface hairline treatment can reflect the texture of metal materials. The grain of drawing board surface has a straight grain, random grain, ripple and thread wait for main a few kinds.

Polished Stainless steel is use polishing fluid through polishing equipment on the stainless steel plate surface, iron-red powder, nitric acid, water as the grinding medium, to wool felt grinding formed the surface so that the board luminosity as clear as a mirror.

2、Different application

Hairline stainless steel is like long and short lines covered with stainless steel plates, forming different lines as decorations for the appearance.

The stainless steel mirror panels can be collectively referred to as stainless steel mirror panels like glass mirrors, which are used in different high-end decorations.

According to the requirement coefficient, there are 8K for normal grinding, 8K for ordinary fine grinding, 8K for fine grinding, and 8K for super fine grinding.

With the design of surface, those materials were mainly used in kitchen tableware, elevator decoration, large shopping malls and so on.

While the hairline finish treatment remains the major choice by the people who prefer less gloss. And those who like to see fewer fingerprints on the surface.

Still, people are loving to adopt the glossy mirror surface stainless steel. Why? It has a unique and aesthetic shining appeal after all.

Besides, a smoother surface can make cleaning easier somehow. This is because there are no tiny cracks and there is no place for dirt to stay. Just remember not to scratch the glossy surface by accident.

To sum up, your personal preferences and installation conditions determine your choice of the hairline or mirror-polished finish for stainless steel.

The common stainless steel finishes on the market

Electropolish

Electropolishing is an electrochemical process removing material from a metallic workpiece.

You might find it in other names: electrochemical polishing, anodic polishing, or electrolytic polishing.

In the stainless steel industry, electropolishing stainless steel is a “reverse plating” process. The method uses electrochemical solution to remove the outer skin of a metal part.

As a result, the electropolishing surface treatment significantly improves a part’s corrosion resistance. And leaves it with a lasting bright finish.

Bead blasting

The finish treatment of bead blasting is an ideal choice for stainless steel used in marine and food industries.

As well, it is common to see in repairment for automotive and motorcycle parts.

This is because it can make the stainless steel dull and hence removes weld discolouration. At the same time, retain a smooth and natural surface without changing the underlying surface.

2B Finish

The 2B finish is the most common choice for industrial finishing of cold-rolled mills.

When beauty is not the most important requirement of stainless steel products, the 2B finish can take place.

It’s not applicable for deep drawing applications though. Still, you can find their footprints in various situations.

Stainless steel with 2B finish can produce a dark grey, slightly reflective stainless steel finish. And, it is the starting point for many other polished stainless steel finishes.

People may use it to make ovens, chemical plant equipment, dyestuff room equipment, tableware.

Plus, laundry and dry cleaning equipment, bathroom fittings, refrigeration, sewage treatment, sheet metal products and vacuum drum dryer as well.

No. 4 Finish

No. 4 finish treatment has a low gloss, and perhaps remain the easiest to maintain.

The production of no.4 finish comes with short parallel polishing lines. And mechanically polished with abrasives after that to provide the best overall stainless steel appearance.

Moreover, it is generally the main stainless steel finish for light manufacturing.

People often use stainless steel with no. 4 finish treatment to make surface, armrest and beautiful products.

Besides, the mechanical polishing with abrasives provides the best overall stainless steel appearance.

That’s why it has another name as “satin” or “lining”.

Also, it is a universal finish. You can find it in restaurant and kitchen equipment, storefront, food processing and dairy equipment. Building wallboards, beverage equipment, ship accessories, road tanker trailers, hospital surfaces and equipment, instrumentation and control panels as well.

No. 8 Finish

It is a kind of mechanical polishing treatment, which can obtain bright and nondirectional polishing through fine abrasive and buffer.

A high reflective polishing effect as a result.

The grit lines on the surface of No. 8 finish stainless steel are almost invisible. But if you look at the surface carefully, you can see them.

However, people use this process to produce a mirror stainless steel finish.

So, there is jargon for no. 8 finish in the stainless steel industry, which is, “mirror” finish.

The applications of this stainless steel finish include cleanrooms, column covers, mirrors, decorative trim, pressure plates, reflectors, signage and wallboards.

As there are many surface treatment options, usually need help to decide which one fits the best of your case.
