Steel Building Accessories & Options

Your Steel Building, Your Way.

Every Agricultural and Commercial Operation has its own needs and goals. At Topline, we custom build each steel building to fit the specific needs of the customer.

Looking for column-free space for large equipment or riding arenas? We can help. Need ventilation and insulation accessories for commercial chicken coops and livestock pens? We’ve got that covered, too. When it comes to space for commercial storage, security for tools and equipment, or protection of your livelihood from the elements – Topline has the expertise to help you achieve your goals.

Insulated steel building Options

Premium – If you want to maintain tight temperature control and spend the least on energy expenses over time, our Premium Insulation provides the best option. Designed to fit snugly between purlins, our Premium Insulation remains compression-free and offers your steel building the best protection available. Our Premium Insulation Package also gives a finished look to the roof, while providing a high insulation R-value of up to 40.

Midgrade – If you’re looking for a slightly lower R-value but similar appearance, try our WMP-50 Fiberglass Insulation. The improved vinyl and nylon facing is 200% stronger than traditional insulation packages, which enables the installer to stretch the insulation tighter, creating a flatter and cleaner look. The increased strength also helps prevent birds and other animals from picking holes in the insulation facing.

Base – Though WMP-VR Insulation is our base level for metal buildings, this traditional fiberglass insulation can provide a great buffer between you and the elements. Available in a wide range of “R” values, we’re sure to have the level of protection best suited to your operation’s needs.

Overhead steel building Doors

When it comes to the size, placement, and number of overhead doors, Topline Steel Buildings offers great flexibility and variety. We can go as slender as 8 feet, and as broad as 36. Doors can be ordered both with and without insulation. Other options are available as well.

Walk doors for metal buildings

Like our overhead doors, our walk doors come in a variety of sizes and styles. Each and every door comes with a lock and handles. Glass (and glass sizes), closures, and insulation properties can be adjusted according to your wishes. Just let us know your needs or specific preferences and we’ll custom build it to fit your operation.


Add natural light to your metal building with insulated subframe windows. Windows come in a variety of sizes and can either be a fixed picture or horizontal sliding to open. Common sizes include 3’x3′, 4’x3′, or 5’x4′, but we can also customize sizes to meet your needs.
