The trims are metal sheets in parts that are folded. They work to keep the roof waterproof.  

The large lengths maintain consistency. Their application is very simple for makeovers of the home or shed.

Generally, water damages different parts of the metal roofing during rain. But metal trims will seal the joints and keep off moisture. They will allow roof panels to connect from edge to edge in the roof and give a polished look.

Types of Metal Building Trims

Here we discuss different metal building trim types:

Roof ridge cap

This one offers an intersection between two roofs at the ridge. So, the roof is free from leakage and rain.

Metal Building Eave Trim

Eave trim

This custom trim stays at the roof’s end and also at the top of the panel. It offers an aesthetic look. It also prevents moisture to enter the wall and panels. 

Gable trim

Gable trim

Gable trim offers a panel that remains water-resistant. It is placed between the panels of the wall. For this, it can block steel plates and prevent water from coming inside. 



We can place this on the edge to lead the rainwater to a downspout. So, instead of collecting on the steel roofing, the water will flow towards the ground. 

Wall Corner trim

Wall Corner trim

As the name says, this trim remains at the wall’s outside corners. So, mostly it works for the decorative part but also removes water so that it doesn’t enter the building. 

Metal Building Base Trim

The intersection of the panel and wall is made of a base. This trim will cover this base and prevent any water from entering the building. It even covers the metal building windows and the doors.

Metal Building Rake Trim 

This is an angled trim to fit the roof pitch. So, the trim can cover the seam of the roof. Both the roof panels and end wall panels are covered with no overhanging roof line. 

J-Channel Trim

The J-channel trim offers a very sleek appearance. These are quite efficient and easy to clean. Having J-channel trims makes windows and siding installation extremely easy and seamless.

Jamb Trim

If you want to add extra protection across your doors and windows, you must depend on jamb trims. Featuring a polished appearance, these would help remove extra water and debris.

Valley Trim

The valley trim protects the intersecting panels of the two slopes. Since it is shaped in a valley-like format, it ensures the water easily runs off without causing any leaks or external damage.


If you’re looking forward to combining functionality and aesthetics in metal trims, nothing can work better than Z trims. These add depth, thereby creating the desired visual appeal.

Hemmed Eave Trim

This type of trim is mostly used on the edge of the roof. Since the edges are secured, there is no risk of damage due to water infiltration.


Fascia helps in covering the roofline. It provides a watertight seal across the roof, thereby protecting the aesthetic appeal of the roof.

Fitted Ridge Trim

As the name suggests, the fitted ridge trim protects the roof’s ridges. The roof’s highest point receives a watertight seal, thereby enhancing a finished appearance.

Sidewall trim

Rather than the roofs, the side wall trims often protect the sides of the walls. Contrary to the other methods, the side wall trims are installed vertically. As a result, the frames are protected against any potential damage.


Endwalls are installed across the end of the building. With a finished edge, there is no risk of water intrusion. As a result, there is no potential damage.

Metal Building Corner Trim

With the help of corner trim, you can easily protect the extreme corners of the exteriors. With increased strength and durability, the corner trims offer a clean and sleek appearance.

Drip Edge

One of the major functions of drip edge is to prevent the water from seeping in. Since it is installed across the roof edges, the water will be redirected to the fascia, preventing damage to the entire structure.

Material Used in metal building Trims

Functionality, aesthetics, and durability are the three primary criteria for selecting materials for metal building trims. Take a look below to understand what materials to choose from:


The strength and affordability make steel an absolute favorite for metal building trims. The effective structural integrity of steel makes it an efficient choice, as it can effortlessly handle harsh weather conditions. And it’s not only functional but also aesthetic, as steel provides a sleek and modern look.


Whether you want to use aluminum for exteriors or interiors, these suit the purpose of resisting corrosion. Being lightweight, aluminum is extremely versatile and can be molded into designs of personal preference. Aluminum is one of the prime choices because of low maintenance and is fading and dust resistant.

Galvanized Steel

Galvanized steel, with its additional zinc layer, helps offer protection against corrosion. Owing to its durability, the galvanized steel trims can easily withstand moisture. Therefore, if you’re in a high-humidity area, you must opt for the galvanized steel trims.

Stainless Steel

Whether it’s heavy damage, corrosion, or rust, stainless steel trims are here to fight it all. With a modern and polished appearance, stainless steel trims enhance aesthetics. As far as functionality is considered, these can serve well across healthcare facilities and food processing plants.


With their distinct patina, the copper trims add character and charm to the buildings. If maintained properly, the copper trims can last for generations serving numerous benefits.


You can never go wrong with zinc trims. These are highly suitable for areas with high humidity, especially coastal areas. You don’t have to worry about corrosion if you have zinc metal trims, for they can eventually help get rid of it all. Also, it’s lightweight and doesn’t require much maintenance, so you can use it without burning a hole in your pocket.

Effects of Metal Building Trims

Whether trims offer an intersection or remain at the edge, corner, or angle, their purpose is to cover the opening. This will either block the rainwater or make them flow to a different route. 

Besides, the color options, shape, and finish of each trim offer a beautiful structure.

Why is Opening Trim for Metal Buildings so Important?

Opening trim will allow us to give a polished look to the metal building. We can change the color and texture. Besides, they are used to cover the wall panels and roof edges from all sides. This will ensure that the trims can seal the areas properly. 

Then the roof can remain waterproof by making the rain flow downwards outside the building.
