What does your perforated metal profile say about you?

The unique characteristics of perforated metals

Locker Group has over 60 years experience in the business of manufacturing perforated metal. We produce a huge range of perforated profiles, and each has its own unique, distinctive character. But what are the characteristics that make each product unique? It's not just a shape, it's a personality, so without further adieu, here is what each profile has to say for itself.

Perforated metal profile: Champagne


Champagne is literally the life of the party, but not in an obnoxious way. Interesting, witty, and not afraid to be a little bit silly, Champagne is naturally charismatic and turns heads without even trying. It's said that Champagne once performed karaoke for 36 straight hours and only stopped because there were no songs left. Champagne might not be for everyone, but no one can deny its magnitude.

Perforated metal profile: Aztec


While Aztec has its fair share of academic credibility, it certainly doesn't think it's better than you. Well-read, well-traveled, and concerned for the wellbeing of all living things, the uninitiated may refer to Aztec as a "hippy" though in truth it's a hard-working profile that is proactive about bringing about positive change in the world. Fun fact: Aztec is fluent in three languages and continues to appear as a guest lecturer at Universities around the world.

Perforated metal profile: Sheer 2800 / Hexagon

Sheer 2800

Sheer 2800 (or Hexagon to its friends) is smart and creative, like a scientist with a flair for experimentation. Obsessed with the complex geometric relationships of living cells*, Hexagon is a leader in its field and tends to garner respect from all corners. Though it seems fairly simple at first, Hexagon is more impressive every time you look at it and even its detractors will admit there is something intrinsically fascinating about this profile.

*We're not sure what this means either, you'll have to pick up Hexagon's latest book.

Perforated metal profile: Ribbon


Ribbon is often the shyest of the profiles, but when it comes out of its shell you'd be surprised by how kooky and fun this profile can be. Ribbon tends to view the world through the eyes of a child, and when you interact with it, this tendency sometimes rubs off – leaving you to enjoy a wondrous world of colour and shape. Ribbon enjoys play-doh, fire-engines, and spaghetti.

Perforated metal profile: Niche

Niche 250

Not a lot is known about the profile that is Niche. Some say it was created in a small town on the SA/NSW border in the late 1970s, others say that Niche has simply always been. Niche is a night-dweller with a serious composure, often preferring its own company to that of others. Highly motivated and darkly attractive, rumours persist that Niche is either a sith lord or a vampire. Attempts to confirm either rumour have been met only with maniacal laughter.

Perforated metal profile: Herringbone

Herringbone 19

Remember the good old days? Herringbone certainly does. By no means a simple profile, Herringbone has a certain depth and elegance all its own. It would be wrong to call Herringbone a relic, since this is a modern profile in a changing world. Quietly wise, Herringbone has seen it all but won't stop smiling – it knows that best of times is still to come. Herringbone was a confidante of Ernest Hemingway and supposedly taught Stephen Fry everything that he knows.

Conveyor belts are essential to the food industry, but which is best - plastic or metal?

4 benefits of using metal belting in food manufacturing

Food manufacturing relies heavily on conveyor belt systems. Not simply because it's far more efficient than manual labour, but because it's considerably cheaper in the long run. Food manufacturing has to stand up to extremely stringent regulations, and processes differ greatly between different food items.

What works for raw meats won't work for baked goods, so it's important to invest in the right system. Conveyor belts can be made of numerous materials, but we believe that metal is the ideal option for food manufacturing. Here's why.

1) Metal conveyor belts easily meet sanitation requirements

A recall is an enormous headache for those in the food manufacturing industry. Not only can it be extremely expensive, it can also do irreparable damage to a manufacturer's reputation. Metal belts are capable of withstanding the extremely high temperatures and pressure required for sanitation. An additional benefit to metal belts is that they are nonporous. Plastic belts are easily chipped and scratched which can become ideal locations for hazardous chemicals or bacteria.

Is a metal conveyor belt ideal for bread?Metal conveyor belts are perfect for food applications, they can easily manage any temperature and are easy to sanitise.

2) Metal conveyor belts can withstand extreme temperature variation

Food processing will require cooking or cooling, and metal excels in both of these areas.

In addition to sanitation, the heat resilience of metal gets extra points for functionality. Some applications of food processing will require cooking or cooling, and metal excels in both of these areas. A thermal expansion coefficient dictates how a material can expand, contract or otherwise change shape with temperature fluctuations. Most metals have a fairly low coefficient, meaning they retain heat when subjected to temperature change. Plastic can easily melt, warp or simply break during processes that metal will roll through easily.

3) Metal conveyor belts are less environmentally taxing

While virtually no manufacturing operation is without a carbon footprint, plastic is far more taxing on the environment to produce. Plastics are made from petroleum, which isn't exactly the poster child for sustainability. While the production of metal does result in pollutants, the sector has made strides in recent years.

4) Metal conveyor belts offer great flexibility

We don't literally mean the ability to flex, but rather, there is a metal solution for every pain point in food manufacturing. Metal conveyor belts generally have a greater ratio of open area which means they are ideal for baking, cooking, or any application where drainage is important. Furthermore, metal belts can be used effectively in conveyors with singular or multiple tight turns, which reduces the need for manual transferral to another belt.

Locker Group manufactures conveyor belts to any width or length, capable of withstanding temperatures between -250 and 1200 degrees celsius. Our belts are assembled in modules to simplify the maintenance process. Whatever you're cooking, Locker Group has the belt for you.

Painting your metal products is much easier than you might think, as long as you do the right prep.

How to paint your metal products

We've talked about the myriad of uses for welded or woven wire mesh and perforated or expanded metal before, but what if you need to paint these materials? It can add a new dimension to a completed project, whether making them stand out from, or to more cohesively fit in with, an environment. Thankfully, painting your metal products isn't difficult, but there are a few things you should know going in.


To start with you'll want to ask yourself a few questions:

  • What kind of metal are you painting?
  • How does this metal need to be prepped for paint?
  • What are the environmental conditions the paint will need to withstand? 

These questions will help you determine what kind of coating you need to use, and what the surface will need before you approach it.

Ferrous metals are those that contain (or are derived) from iron. These materials are far more susceptible to rust, and will begin to do so as soon as they are in contact with moisture. The first thing you should do with ferrous metals is remove any existing rust. Even if your sheet is brand new, it's worth brushing or sanding the surface once over as a precaution.

Aluminium and galvanised metal will require a thorough wash and rinse to remove oil, dirt, and in the case of galvanised metal, zinc chromate leftover from the galvanising process.


Ferrous metals need to be primed as soon as you've prepped the surface. Because it's so easy for these materials to rust, it's best to reduce the time they are exposed to moisture. You'll need to use a rust-inhibiting primer here, and to stay on the safe side it's recommended you do two coats. For galvanised metal you should use a corrosion-inhibiting primer because it's less susceptible to rust.

Aluminium (generally) falls into two camps. If it's anodised, you'll only need to make sure it's clean before painting. If it's not anodised, you'll want to make sure any oxidation is removed. From there, you can treat it as essentially ferrous- it must be primed as soon as possible to prevent the surface from being corrupted.


In terms of top coat, the best bet is to use an exterior latex acrylic paint. This is not the only paint that can be used, but it's likely it will suit the application of metal quite well, and will last longer than other types. It should be available in either a spray can or in larger quantities if you'd prefer a brush or roller. It's recommended you use a spray for more complex or detailed profiles.

Direct-To-Metal (DTM) coatings are also available, which basically mix the primer in with the topcoat for direct application. This can work well, but make sure you check that the DTM you're using will work for your application (both the type of metal and the conditions it will face).

Meshstore's quick guide to sheet metal and wire mesh cutting tools.

What are the best tools for cutting wire mesh?

At Meshstore we sell most of our metal sheets in pre-cut sizes. Most of you will know however, that some jobs require precision. Whether you're trimming a few millimetres off the side or cutting custom shapes, you need the right tools for the job. Certain methods can leave abrasive burrs or distortion. 

Here is Meshstore's quick guide to cutting your perforated metal sheets.

What are the variables?

Before going any further we need to understand the variables. If you've just Googled "how to cut metal sheets" we're sorry to say there's more to it than that. Metal sheets aren't created equally, so you need to have a few more specifics to figure out the way forward.

  • Firstly, what is the nature and profile of this sheet? Is it perforated or expanded metal? Is it wire mesh? There are significantly different methods for each.
  • Next, how thick is this sheet? Thinner materials will be easier to cut. What kind of metal are we talking about? Steel is typically harder than aluminium, so this will also need to be considered.
  • Finally, think about your application. Will burrs be dangerous? Does it need to look tidy? Are there any other application specific considerations to make?

What are the best tools to use?

While punch presses, lasers and plasma cutters typically achieve the greatest result (simultaneously sounding rather cool), these resources aren't exactly readily available. Here are our alternative recommendations:

Snips – These are fairly common and cheap, hobbyists may already have a pair and contractors certainly will. Snips are great for cutting thin sheets and wire mesh and are even capable of delicate curves, but you may run into difficulty at lower gauges, particularly if the metal is quite hard. Snips may leave burrs.

Hacksaw – Like snips, chances are most DIYers will already have a hacksaw. Great for thicker gauges that snips can't manage, but harder metals can chew up blades fairly easily. It's very hard to get curved shapes with a hacksaw and the finish will largely depend on the blade you use.

Angle grinder – Powered and portable, an angle grinder can tackle much thicker gauges. An experienced hand may be able to get good curved results, however this might be trickier if you've not used one before. Fast and efficient with a relatively clean cut.

Power shears – Small, powered shears take small bites out of the metal as you manoeuvre the tool across your intended path. They require a little bit of elbow grease to steer properly, but with a bit of practise you can cut complex shapes with power shears. They will often leave a serrated edge that will need to be handled with care. Power shears and angle grinders are both available at your local hardware store.

There are also a number of benchtop cutting tools for more those handling sheet metal and wire mesh more frequently, but that is a matter for another day. Meshstore's range of wire mesh, perforated and expanded metals are suitable for projects of all types. To find out more, pop into a branch today.
