Ultimate FAQ Guide to Stainless Steel Grilles

What are stainless steel grilles used for?

Stainless steel grilles are generally just covers for some opening.

This may be a vent, a drain, a door opening.

Such covers protect any mechanism or application inside the opening, protect any person from accidental tampering, or guide air and heat.

Another type of grilles that we offer are cooking grilles, which provide a surface over an open heat source.

These may include picnic cooking fires or barbeque grills.

   Stainless steel grille

Of course, it doesn’t have to be a heat source since grilles are often used in fridges and freezers as shelves.

In summary, grilles are either covers or surfaces for any imaginable application and use.

Is stainless steel better than other materials for grille?

Stainless steel is more resilient to various weather and other conditions. 

For example, sun rays, rain, salt, and wind.

This is great for outdoor grilles like sliding door grilles and some vent grilles.

Also, if you plan on requesting a grille for cooking, such as a flexible grille basket, a foldable charcoal grille, or a grille rack, then stainless steel is better than cast iron.

  Cast iron grille vs stainless steel grille

It is so because stainless steel retains heat better, meaning that you can save on gas or other fuel.

Furthermore, stainless steel protects from rust, so the grille will serve you longer than other types of steel would.

If you need bathroom drainage, stainless steel won’t rust from constant contact with water.

Usually, 14 gauge steel is used for grilles, which is about 2 mm.

Is 304 or 316 stainless steel better for a grille?

Stainless steel grilles can be made with steel grades 304, 316, and 430.

Stainless steel is created by adding chromium, nickel, and molybdenum in different proportions to the iron-carbon alloy.

Steel grades 304 and 316 differ in the content of all additives.

316 stainless steel provides the best protection against salt spray, certain acids, and high temperatures.

Grade 316 is slightly stronger and resistant to saline and acidic water because of molybdenum.

Stainless steel

This is why 316 is used more for grilles in harsher environments.

But grade 304 is cheaper and more common in general use.

This is why most stainless steel grilles use 304 steel.

This grade is durable as well.

It is also 316L or 304L.

Grades 316L and 304L have a lower carbon content, making it a little bit stronger.

However, they are not very frequently used on the market.

Steel grade 430 is also very popular and cheap, but less durable than grade 304.

Do stainless steel grille rust?

‘Stainless’ is a little misleading; this type of steel does get stained, but it does not rust.

Stainless steel does not rust unless they come in contact with concentrated bleach.

This is why it is important to clean your grille, but not too zealously — with harsh chemicals.

Stainless steel can become discolored, appearing like rust, but it is not corroded.

Tea-staining

This is known as tea-staining, but it does not affect the lifetime of your stainless steel grilles.

Smoke and salt are examples of substances that can discolour your stainless steel grille.

However, if that happens, only the aesthetic value of the grille is damaged, not the steel.

Where should stainless steel grilles be installed?

This depends on the type of grille that you need.

If you are looking for a vent cover, then these are typically installed on the ceiling or upper or lower part of the wall.

If you want to cool your room, then ceiling vents are better, but if you are looking for a heating vent, then the floor is best.

Furthermore, vent grilles can be installed on the floor if you have heating floor ducts.

If you want a cooking grille, then these are portable and can be stored anywhere!

Cooking grille

Except, if you want your grille permanently installed in an oven, fridge, or restaurant food storage spaces.

Grilles can even be used as surfaces on a trolley.

We also offer bathroom drainage grilles that are installed into the floor of a walk-in shower.

This is done for aesthetic value and to make sure all the water gets drained—linear grille drains do that better than regular drains.

Also, regular drains are recessed into the floor, being lower than the floor surface; this may be painful to step on, and our grilles level this surface.

As a result, you don’t notice sharp edges if you step onto the drain.

 Bathroom drainage grille

Finally, we offer a range of door grilles.

These can be either safety grilles or ventilations grilles.

Safety grilles, or sliding door screen grilles, are used to deter burglars and increase the security of your house, office, business, anything.

They also have a classic aesthetic value.

Ventilation door grilles are installed into a door to provide a pathway for air to move through rooms.

These are common in commercial kitchens, pools, and other such places.

Of course, we also offer general-use grilles and punch-sheet grilles for any application.

How to install a stainless steel grille?

Grilles are very easy to install.

Cooking grills generally don’t require any installation: they are either used as is, or they can be easily placed into grooves in an oven or fridge.

Vent and bathroom drainage stainless steel grilles can be easily screwed in place.

Installing vent stainless steel grille

However, sliding door and door vent grilles are more problematic.

Door grilles would require a hole in the door, which is a complication.

But once there is a hole in the door, installing a grille is simple.

Sliding door grilles may require professional help, depending on the design of the grille.

It may require the installation of a track, or you may be able to install it yourself with simple fasteners.

Either way, stainless steel grilles are not troublesome in installation and maintenance.

How long do stainless steel grilles last?

Grilles are simple, they are not mechanisms that get worn out.

Plus, our grilles are made from stainless steel, making them very resistant to heat, corrosion, impact, dust, and everything else.

Therefore, your stainless steel grille—no matter what the design or application is—will last for years.

For example, sliding door grilles can last up to 30 years, whereas charcoal cooking grilles are known to last up to 15 years and more!

So, with our stainless steel grilles, you don’t have to worry about running out of its time.

Is it possible to make a grille for a curved surface?

Yes!

It is possible to manufacture vent grilles and sliding door grilles for concave and convex surfaces.

This may be needed if you have rounded corners in your residential or commercial location.

For a sliding door grille, a curved track will be necessary.

What is the difference between a register, a grille, and an air return?

Grilles are vent covers, racks, or cooking surfaces, which allow air and heat to pass through it without control.

Registers are also vented covers, but they have dampers to open and close the vent to control airflow.

An air return is basically a grille that passively guides air into some central system like a heating or a cooling unit.

Air return, register, grille

If you need to adjust vent airflow, then a register is helpful.

If you need a simple generic vent cover, then a grille is perfect, but if the vent cover is for a system vent, then air return should be used.

Registers are also usually placed on floor vents, whereas other vent covers go on the walls and ceilings.

What filter additions do stainless steel grilles offer?

Sometimes, adding a filter to an air vent or a bathroom drainage grille is a good idea.

The extra filter cleans the air before it reaches some central air filtering system, prolonging its life.

Such grille filters are often soft pieces of foam, fiber, or fabric that are easy to install and service.

   Filter on a grille

What cooking grilles can I request?

Grilles are mostly used for outdoor cooking.

We offer stainless steel racks, foldable charcoal grilles, and even grille baskets.

Stainless steel grille racks are flexible multi-purpose grilles that can be used to cook over a fire, roast in the oven, as a surface to frost cakes, or even to cool baked food.

These are available in a square or circular design, but the latter is more popular than the former.

Stainless steel grille rack

Foldable charcoal steel grilles are perfect for picnic steaks and roasting vegetables over the fire.

Usually, 15-20 coals are used for one picnic.

We offer portable grilles that you can fold for your convenience.

Foldable charcoal steel grille

These grilles are lightweight and durable, giving you motivation to go on a picnic.

Stainless steel grille baskets are ideal for the best grilled fish.

These grilles are difficult to clean, but they are very portable and easy to use.

Usually, they have wooden or plastic handles, so you don’t burn your hands; metal handles may conduct heat.

Stainless steel grille basket

So, if you like grilled or fried fish and chips, a basket is for you!

Is it safe to cook on a grille?

Cooking on stainless steel is perfectly safe; you just have to preheat the grille first.

Cooking on gas like propane tends to be healthier than cooking on charcoal, but that has to do with the fuel, not the type of grille.

How do sliding door stainless steel grilles work?

Sliding doors have a stationary panel and an operating panel that moves sideways or extends.

These stainless steel grilles can have a simple design that does not fold, but just slides away, such as a linear design.

Simple sliding door grille

Another design of a sliding door grille is a more complex one, where lines of steel interlock so that they can be folded, saving space.

Both designs grant security.

These door grilles may also require a locking mechanism to make sure the door grille stays in place.

Most often, such sliding door stainless steel grilles are used for commercial applications: to secure stores and malls at the end of the day.

Complex sliding door grille design

However, it is possible to install one in your backyard as well.

Stay safe!

Where can I install bathroom drainage stainless steel grilles?

Bathroom drainage stainless steel grilles can be installed in a walk-in shower.

The surface of the shower does not matter much; you can install a drain grille on a tile floor, as well as other types of bathroom flooring.

Subflooring also does not matter much, as you can request a stainless steel drainage grille for wooden and concrete subfloors.

  Stainless steel drain grille

What are common stainless steel grille design features?

Stainless steel grilles encompass many applications, designs, and features.

Some features you can request include single- and double-deflection adjustable-blade grilles, fixed blades, louvered, perforated face or egg-crate grids.

Single-deflection blades for vent covers represent rows of blades that can be adjusted to restrict or loosen airflow.

Double-deflection blades have both rows and columns set at 90 degrees for greater control over the flow of air.

Deflection types

Adjustable blades in when you can change the angle of the blades, controlling airflow, whereas in fixed blades you can request them to be permanently at 0, 14, or 45 degrees.

Grille with adjustable blades

Louvers are horizontal slats that cover the opening.

They are angular to let in air, but keep rain or dripping condensation out.

  Louvered vent cover 

There are several designs of these louvers, such as single-slat or double-slat.

Single-slat louvers face out, but double-slat can face either way like adjustable blades.

Perforated-face grills are basically punched sheet grills.

Egg-crate grilles are perforated-face, but their holes are usually in square shape.

Egg-crate grilles look like double-deflection, but in double-deflection, there are columns of blades, whereas in egg-crate grilles there is just a cage pattern.

Egg-crate grille

What bar designs are there for stainless steel grilles?

There are 3 main bar designs for grilles.

These can be used in security applications like sliding door grilles, or in cooking.

This is because vent stainless steel grilles use another type of design: blades.

One design is when bars are welded at cross-points.

Welded bars for stainless steel grille

This one is the easiest to manufacture, but it is also durable.

Cooking grilles use this design most often, while the next two designs are popular with sliding door security grilles.

Another design is when there is a horizontal flat bar that vertical bars go through.

 Bars with flat bar

These are very secure, but are slightly harder to make, and they don’t look as aesthetic as other bar designs.

The final bar design is similar to the first design, but the crosspoints are enforced with welded clamps.

Enforced welded bars for stainless steel grilles

Obviously, this design is the most difficult one to manufacture.

However, it combines the strength and aesthetics of the previous two designs.

How to remove vent stainless steel grilles?

If you decide to add a filter or clean the grille, there are a couple of ways to remove it from its frame.

You can install either a removable core or a hinged core grille.

Removable cores are fitted with spring-loaded fasteners.

The outer frame has brackets, while the inner removable frame holds slotted head studs

You can remove the inner frame with a screwdriver, Allen keys, or just your fingers.

The inner frame then pops out and can be easily cleaned.

However, this may not be optimal for applications when you need to remove the grille often.

 Removable core

In this case, you can request a hinged core.

For the inner frame to hinge out, a full-length piano—or continuous— hinge is installed at one side.

It is discreet, and ensures minimal loss of core area, meaning that you can make the grille bigger and more efficient.

The inner core is held in place by a fastener, small lock, or a clasp.

Hinged core

Hinged cores allow you to access the vent quickly.

What can stainless steel punch sheet grilles be used for?

Generally, for anything.

Most often, these grilles are used as vent covers.

Because of a circular—or any other—pattern of holes, this grille offers a different aesthetic quality than regular grilles.

This is why these covers get requested for various commercial locations like restaurants, and residential homes.

Punch sheet grille shapes

The pattern is universal and can be customized in several ways: the density of holes, diameter, and shape.

Some shapes include diamonds, clubs, crosses, squares, honeycombs, ovals, and much more.

The finish can also change how the grille looks, so if you need an aesthetic vent cover, punch sheet grilles with satin polish or epoxy paint.

Contact us today to discuss your design idea!

What coatings for stainless steel grilles are there?

You can request satin polishes, epoxy coatings, and anything special like phenolic coating.

Satin polish is an abrasive polish that uses aluminum oxide as an abrasive substance.

This finish produces a fairly smooth surface good for any application of a steel grille, but especially so for cooking.

There is also a brushed finish, which shows lines and is rougher to touch; brushed finish may not be great for cooking because the tiny grooves accumulate grease and are harder to clean.

  Brushed vs satin polish

Epoxy coatings consist of an epoxy resin and a hardener.

This type of coating is very durable and is suitable for harsher applications like vent covers, door grilles, and bathroom drainages.

We offer epoxy coatings in clear and white colors.

Phenolic coatings are special epoxy coatings that can be extra corrosion- or heat-resistant depending on the formulation.

 Reddish phenolic coating

These coatings often have their own color, so it is common to request an additional paint coat to cover it up.

Typically, epoxy coatings are not used for cooking, but for other applications.
