Extruded Aluminum Trim: The Ultimate FAQ Guide

Choosing a suitable extruded aluminum trim can be an overwhelming task.

However, this guide will make everything simple and straightforward for you.

So, keep reading to learn more.

What Is An Extruded Aluminum Trim?

 Extruded Aluminum Trim Used In A Residential Project

Extruded Aluminum Trims Used In A Residential Project

An extruded aluminum trim is an aluminum billet or ingot that has undergone extrusion to create long, narrow and adaptive pieces referred to as trims.

Due to their adaptability, the trims are widely used in various architectural applications, lighting, and engineering designs.

Other exceptional features of extruded aluminum trims include:

  • Accurate dimensions
  • Super tolerances
  • Customized design

How Do You Manufacture An Extruded Aluminum Trim?

The method used in manufacturing extruded aluminum trims is the extrusion process.

Extrusion generally involves forcing metal through a die, consequently converting it to the desired shape.

In extrusion, there are two main aspects to consider:

  • Billet – a small bar of metal (in this case aluminum) that is set to undergo further processing.
  • Die – a hollow profile of required cross-section that forms thin, narrow, long trims.

During extrusion, the billets are forced through the die by a ram, forming aluminum trims.

Extrusion Process

Extrusion Process

There are three main types of extrusion:

  • Cold extrusion – Carried out at room temperature.
  • Warm extrusion – Conducted slightly above room temperature
  • Hot extrusion – Done in extremely high temperatures (Commonly used for aluminum trims)

Lastly, to increase the aluminum trims’ corrosion resistance features and strength, the trims usually undergo post-heat treatment.

What Are The Common Applications For Extruded Aluminum Trims?

You can use extruded aluminum trims in several applications.

The extruded aluminum trims are widely used in houses for decoration and protection. Common examples of interior design usage include:

  • Stair antiskid or stair nosing
  • Handrails
  • Living room decoration
  • Table edge protection
  • Cabinet decoration
  • Bedroom decoration

The typical applications of extruded aluminum trims include:

  • Decorative Building Construction, for example;
  • The Hat channel aluminum trims act as a decorative divider between wall panels
  • Z-channel aluminum trims act as receivers for ridge caps and panels during roofing.
  • Countertop edging
  • Car interior decoration
  • Protecting and decorating the edges of glass, tiles, marbles, UV board, etc. For example, edging a tile using an aluminum trim will prevent it from chipping.
  • Woodwork projects such as a table, chair, and workbench edging
  • Housing LED lights. This specific application is for the round aluminum channel trim, which is hollow hence can host the LED light strips.
  • Creation and designs of portable displays. Commonly, the aluminum trims act as grooves for sliding the display glass or boards.

Note: Trims designed for use in the car’s interior are more detailed and smaller. Additionally, they have a pattern or a surface texture.

What Are The Types of Extruded Aluminum Trims?

Extruded aluminum trims have many applications. Consequently, there are various types to cater to the different uses.

Typically, the significant difference of the aluminum trims is in the design. Mostly, the various aluminum trims take the shape of a letter, as we will discuss in a bit.

In other scenarios, other people tend to differentiate aluminum trims depending on the finishing. However, we will only focus on types depending on the design.

Notably, the types named after the letters have a similar design to those specific letters.

U Aluminum Trim

For the longest, the U trim use is mainly for edge protection. In that, this trim offers protection from rough edges or acts as a finishing for edges.

The U trim is highly versatile and is used in various materials, including glass and wood. Also, it gives your project an aesthetic touch.

J Aluminum Trim

The J trim is used chiefly for leak or moisture build-up prevention. It is installed on the edge of the siding around the doors and windows to create a seal.

You can also install it on the upper part of the siding to hold it in place.

J Aluminum Trim

J Aluminum Trim

Z Aluminum Trim

Similar to J trims, the Z aluminum trim also prevents leaks. However, they are installed alongside metal roofs and act as receivers for ridge caps, headwall flashing, and panels

H Aluminum Trim

The H trim offers stability and strength on door and window frames. Also, they can play an aesthetic role when used on railings.

H Aluminum Trim

H Aluminum Trim

L Aluminum Trim

L aluminum trims can also be termed angle trims since they have a right angle shape. Commonly, their common usage is in table and countertop edging, frames, and braces.

Notably, the L trims can vary in terms of thickness and the length of the sizes. Otherwise, despite the variations, they are durable and robust.

T Aluminum Trim

The shape of the T trims dictates that they need overhead insertion into a project. As such, they are ideal for tile edging, mostly when transitioning tile floors.

The variation of the T trim is on the upper part, which can be either smooth, grooved, or fluted.

Other typical applications of T trim are in woodwork projects, elevators, and store fixtures such as display racks.

Hat Aluminum Trim

The hat trim takes the shape of a hat; hence it primarily acts as a decorative divider between tiles, boards, and wall panels.

Also, its design enables it to divert water and allows the thermal efficiency of a structure.

Round Aluminum Trim

The round aluminum trim is almost similar to an aluminum rod, but it does not form a complete cylinder.

This trim typically acts as an enclosure for LED lights.

Note: Although the above types are the most common, we can further customize the aluminum trim to fit your specific project.

What Is The Maximum Length Of An Extruded Aluminum Trim?

Interestingly, there is no maximum length limit for an extruded aluminum trim – maybe for the diameter, which should not exceed six inches

However, the carrier can limit the length of the trims. Carriers can only carry goods that meet a specific length threshold.

Meaning, the maximum length of the extruded aluminum trim is the maximum length that a carrier imposes.

What Material Is Used To Manufacture An Extruded Aluminum Trim?

Commonly, the 6000 series is the aluminum alloy series used in manufacturing extruded aluminum trim.

The 6000 series include 6063, 6061, 6005, 6082, and 6060.

Notably, the 6000 series has magnesium and silicon added to the aluminum. Consequently, this series has improved elasticity which allows for heat treatment.

Narrowing down, most manufacturers use aluminum 6063 because it has a smooth surface, thus enabling easy fabrication. Additionally, the aluminum 6063 is easy to machine and weld.

What Are Some Ideal Features For An Extruded Aluminum Trim?

For every product, there ought to be some key selling features. These features guide you on whether or not the specific product is the ideal one.

Features you should look out for in extruded aluminum trims include:

  • Easy installation – Installing an aluminum trim should be easy. Although you cannot install every type of aluminum trim without the relevant expertise, installation should be easy for the experts.
  • Long-lasting – The aluminum trim should be long-lasting to save on repair, maintenance, and replacement costs.
  • Economical – Purchasing aluminum trims should not overstretch your budget.
  • Strong and tensile – If the extruded aluminum trim is strong, it will survive in extreme conditions and forces. Consequently, it will last longer and eliminate the need for regular replacements.
  • Excellent finishing – In the construction industry, the finishing is as important as the foundation. The same is true for aluminum trims.

An excellent finishing will boost the aesthetic value of the aluminum trim and make it more efficient, i.e., a coating will protect the aluminum trim.

The good thing is that various types of finishing are applied to the aluminum trims to meet your custom requirements.

What Is The Hardness Of An Extruded Aluminum Trim?

One of the main reasons why aluminum is primarily preferred in extrusion is its strength.

Depending on the grade, aluminum alloys can be five times stronger than steel.

Notably, aluminum has a high strength-to-weight ratio, which also applies to the extruded aluminum trims.

Which Surface Treatment Options Are Available For Aluminum Trims?

Typically, the surface treatments improve the appearance of the aluminum trims. Moreover, the coatings offer protection to the aluminum trims.

There are various surface treatment options used on aluminum trims. They include:


Aluminum trims are anodized through an electrochemical procedure. The resultant trim, after anodizing, is both decorative and smooth.

Also, anodizing boosts the durability and corrosion resistance of the aluminum trims.

Additionally, anodizing results to a coating (aluminum oxide) that forms part of the trim’s substrate. Consequently, the anodized finishing does not peel or chip like other types of finishes.

Notably, you can add other finishes on top of the anodized finish.

Mill Finish

Simply put, a mill finish is a finish that the extruded aluminum trim has as it exits the billet. We can liken this to not finishing at all – you use the extruded aluminum trim as it is.

Aluminum trims with a mill finish have a slight amount of oxidation compared to the anodized aluminum trims.

One way to note a mill finish on the aluminum trim is a semi-reflective or a semi-dull finish. Also, you may note some lines running along the length of the extrusion.


Commonly, aluminum is electroplated using large copper deposits. Consequently, electroplating of aluminum can also be termed as copper plating.

Before copper plating, the aluminum trim is first polished. Subsequently, the aluminum trim is electroplated with heavy copper deposits.

Next, the now copper-plated aluminum trim is again further polished to make the surface smoother. The final step is the activation of the copper surface and electroplating the trim with nickel-chromium.

Significantly, to prevent the plating adhesion from weakening due to oxidation of the aluminum, you should add a zincate before nickel-chromium plating.


Commonly, polishing acts as a predecessor of the actual finishing. Polishing removes materials from the aluminum surface by using abrasives as abrasive media, belts, and wheels.

Powder Coating

Powder coating is the other standard option for aluminum finishing, accounting for more than 15% of the total industrial finishing market.

It involves spraying electrostatically charged powder (which is essentially paint) onto the surface of your aluminum trim.

The typical steps to follow during powder coating are:

  1. Pre-treating the aluminum trim’s surface to remove any foreign particles, including grease, dust, etc.
  2. Next, you will use an electrostatic spray gun to apply the powder paint on the aluminum trim’s surface.
  • The sprayed aluminum trims are then placed into an oven to heat and uniformly melt the powder coating.
  1. Finally, you remove the aluminum trims and allow them to cool. After cooling, your aluminum trim will have a smooth, hardened coating or layer.


Painting is more or less similar to powder coating, with the significant distinction being evident in the procedure.

To paint an aluminum trim, you will follow the below steps:

  1. First, you will thoroughly clean the aluminum trim then allow it to dry.
  2. Next, you will sand the aluminum trim’s surface – first with coarse, then finally with fine sandpaper
  • Before actually painting the trim, you need to apply a self-etching prime, then sand again after it dries.
  1. You can then proceed to apply the paint. If you are using multiple coats – you should sand between the coats
  2. Finally, you will apply the enamel sealer.

A major disadvantage of painting is that it does away with the maintenance-free nature of the aluminum trim

Polyvinylidene Fluoride (PVDF)

Many times, PVDF finishing is confused with powder coating. The main difference is that PVDF is a resin-based liquid coating or finishing, whereas powder coating uses electrostatically charged powder.

In terms of durability, PVDF coatings are more durable than powder coating. However, powder coatings are stronger than PVDF coating.

The similarity between powder coating and PVDF is that both require the aluminum trim to be baked together with the coating to facilitate strong adhesion.

Notably, different types of finishing have different costs attached to them. Arguably, anodizing is the most expensive type of finishing yet ideal for various environments.

Consequently, your choice of a specific finishing will be influenced by your budget and the environment you intend to use the aluminum trims.

What Is The Importance Of A PVC Coating On An Extruded Aluminum Trim?

The primary role of a coating is to offer protection to the material it encloses. Apart from PVC coating providing protection to the extruded aluminum trim it also allows for color customization.

PVC coatings come in various colors, thus you can choose the ideal color for your project.

What Are The Important Certifications For Extruded Aluminum Trims?

Certifications may vary depending on the country of production. Despite the variations, these different certifications draw their standards from the below main certifications:

  • ISO 9001:2015
  • AS9100D
  • IATF 16949:2016 – For aluminum trims used in the automotive industry

How Can I Ensure I Get Quality Extruded Aluminum Trims From The Manufacturer?

When making a purchase, it is advisable to abide to the phrase ‘seeing is believing’ – only trust it is quality once you see it.

In the case of aluminum trims, you place an order before the actual production of the aluminum trims.

Consequently, you may think it is impossible to first see the trims before ordering for them.

On the contrary, you can see a sample of the trims before the manufacturer commences mass production.

All you need to do is request a pre-production aluminum trim sample from the manufacturer.

From the sample, you can gauge the trim’s quality and suggest to the manufacturer what alteration you need.

However, if you have made quality purchases from the manufacturer in the past, there might be no need to request pre-production samples.

What Is The Recommended Standard For The Production Of Extruded Aluminum Trims?

There are various standards put in place for the production of quality extruded aluminum trims. Some of these standards also dictate the quality that the finishing should meet.

The common standards include:

  • GB/T 5237-2008 – Aluminum Industry Standard
  • SGS Standards – For testing and inspection.
  • AAMA Specifications for aluminum coatings (Specifically AAMA 2605-17a)

Is There A Warranty For Extruded Aluminum Trims?

Yes, most manufacturers provide a warranty for their extruded aluminum trims. Commonly, the warranty applies to defective products.

The warranty period can be as long as ten years for original purchasers.

However, the warranty will not come in to effect if there is any alteration to the original extruded aluminum trims.

How Can I Install An Extruded Aluminum Trim?

Aluminum trims are installed in various ways depending on the type and application of the trim. Professionals do most installations.

Moreover, most manufacturers enclose the installation guide when sending over the trims.

Regardless, we will not fail to give you an overview of how to carry out the installation.

  1. First, upon receiving the extruded aluminum trims, you will need to examine them to ensure they are quality.

Commonly, the trims will come with steel mounting clips.

  1. Depending on the installation surface, you will need to have separately purchased installation hardware such as metal screws or mounting anchors (for concrete or block walls). Importantly, for each mounting clip, you will require one anchor or screw.
  • Next, determine the location of the trim on the wall or surface and mark it. However, if you plan to install an aluminum tray, do so first.
  1. With the wall measurements, proceed to cut the aluminum trims to size using a fine-tooth miter saw.
  2. Proceed to install the steel clips 0.0625 inches outside the markings you made on the wall or surface.
  3. You will install the trims to the clips over the angled size of the steel clips. Generally, you will be hooking the trim pieces on the clips while applying moderate pressure with the heal of your hand to the side not locked in. Eventually, the trim pieces will lock.

This installation procedure is not a one-size-fits-all.

However, the various installation procedures will slightly deviate from the steps we have highlighted above.
