Trim Options for Your Steel Buildings

Published January 23, 2015 by Whirlwind Team

Colorful TrimYour trim options play two roles for your metal building. On the surface (literally and figuratively) they provide a tidier and more attractive aesthetic from the outside, and functionally the right trim pieces help your building to better weather the elements, protecting its components from the destructive forces of wind, rain, moisture, etc.

Choosing poor quality trim pieces or incorrect installation techniques can make your building look cheap and shabby and will leave it susceptible to weather-related damage that leads to costly and labor intensive repairs or renovations.

Metal Building Trim Options: Which Ones Do You Need?

You have many options when it comes to the type of trim options you select. The following is a general run down of the different categories. You can always contact your metal building manufacturer to discuss the trim options for your specific building so you implement the components that will work best for your buildings style, function and geographic location.

Before the list gets started, please note that you are much better off spending a little extra to purchase trim pieces that are custom designed for the exact specs of your building than you are buying generic pieces that have to be modified in the field. The modification process often yields trim that are more difficult to install and that compromise the final look and performance of the finished building.

Now, let's look at the most typical trim options you'll be selecting to enhance the look and function of your next metal building.

The Roof

Most of the trim options available to you are designed to merge the transition from one plane of your building to another. Nowhere is this need more prevalent than your roof, which - depending on your building's design - can be loaded with different panel junctures, corners and angles.

Typical metal building roof trim includes:

  • Ridge Caps. These cover the top ridge line of your roof where the panels come together on either side. These caps are often integrated with ridge vents that help to maintain a continuous airflow, enhancing the indoor air quality and temperature of your building as well as to moderate humidity levels and decrease moisture accumulation. The roof ridge can be one of the most difficult areas to fit properly and incorrect installation leads to gaps that will allow birds to nest, pests to infiltrate and can also lead to leaks and corrosion in your building panels.
  • Rake Trim. These trim pieces cover the exterior edges of your roof line, creating an attractive and uniform edge and preventing anything from infiltrating the underneath side of your roof system.
  • Peak and Corner Boxes. As we mentioned before, trim options help to soften transitions and - sometimes - your trim transitions need transitions too! This is where peak boxes and corner boxes come in. They create attractive and tightly sealed transitions on peaks and corners created by the rake trim.

You will also have various trim pieces to choose from depending on the types of features you design for your roof. Additional features and accessories - such as skylights or cupolas will mean another set of trim options to choose from.

The Sides

Your building panels will also require trim pieces along the corners where two wall panels come together. These are called angle trim pieces. You will also use base trim options to transition between the foundation and the bottom edges of your wall panels. Base angles can be used to transition the base trim around the corners of your exterior door frames.

Gutters, Gutter Trim and Downspouts

Potentially one of the most important aspects of your trim installation, gutters and downspouts take moisture runoff from the roof and/or real-time weather elements and direct them down and away from your building. They also keep sheets of water from streaming down on you, guests and/or employees at entry door locations. Steel and metal buildings are incredibly durable and low-maintenance but moisture is their enemy. When well designed, built and installed, gutter and downspouts will also create an attractive accessory for your building, allowing you to introduce a new color to your exterior color palette.

Jamb Flashing

Jamb trim, or flashing, is used to cover the exposed openings caused by a framed window or door. They tidy up the appearance and also seal the opening from critters and the elements.

These are some of the basic trim options available for your metal building. There are multiple variations of each type, all created to suit the specific design of a wide range of metal building types. Working with a professional metal building fabricator will ensure you purchase the best trim options for your building.
