Characteristics of Commercial Doors
A commercial door is designed to be more durable than standard residential models, allowing for higher traffic and more demanding use. You’ll find these doors in businesses, schools, and industrial settings.
Commercial Door Materials
Commercial doors are commonly made from steel or wood. Wood commercial doors typically feature a metal core for added strength and are usually used for interior applications. Steel doors are more popular for exterior or high-traffic use, and at Indiana Wholesale Supply, most of our stocked steel doors include polystyrene cores for sound and heat insulation.
Steel doors are not only durable, but also among the most cost-effective options for commercial use.
Coloring Commercial Doors
Commercial doors are typically sold unfinished and ready for paint or stain:
- Steel doors come with a rust-resistant primer and are ready to be painted.
- Wood doors are usually sold unfinished for on-site staining, but we also offer pre-finished options with factory-applied stain.
Fire Ratings
Fire ratings are an essential consideration in commercial settings. The American National Standards Institute (ANSI) certifies commercial doors and frames based on how long they can withstand fire:
- Ratings include 20, 45, 60, or 90 minutes.
- These ratings are verified by third-party agencies.
- Ensure your door and frame meet the fire code requirements for your project.
Hinge Locations
Most commercial doors include three hinges, but their location can vary based on the manufacturer. Prepped hinge locations are often:
- Wood doors: cutouts and pre-drilled holes.
- Steel doors: factory-made openings with reinforcement.
If you're replacing a door within an existing frame, it's crucial to match the hinge locations. Alternatively, continuous hinges can be used to avoid compatibility issues.
Hardware and Door Prep
Proper door prep for hardware is a key part of commercial door installation. Consider:
- The type of locking mechanism (e.g., panic bar, lever handle, card access).
- Frame reinforcements for closers or electronic strikes.
- Whether hardware will be installed during fabrication or in the field.
At Indiana Wholesale Supply, we can prep doors and frames for your exact needs and offer on-site repair or adjustment if needed.
Door Size and Handing
Standard commercial door sizes:
- Height: 6'8" or 7'0"
- Width: 3'0" is standard; 4'0" is common in healthcare or high-traffic areas.
Consider the handing of the door—whether it swings to the left or right. If you’re unsure, we can assist in identifying the correct handing and frame configuration.
