Bi-Fold Doors

Don’t forget these features and options for your SteelBuilt building!

Each Diamond Door comes equipped with standard features (such as an electric lift motor, a high-quality frame finish, and a sturdy manual locking system) to make the operation of our bifold doors easy and convenient. However, if you are looking for door options to maximize the potential of the door and building, here are a few features you might need to hear about.

The Auto-Lock System

This system makes operating the bifold door one step simpler by automatically unlocking (or locking) when you hit the button to open (or close) the door. Like our standard manual locking system, it provides security to the building. When paired with our remote operating system, the bifold door becomes completely accessible by remote.
The Insulation Package
Read More
The Diamond Doors insulation package provides excellent temperature control and improves the energy efficiency of the building. Shipping cut-to-length, our rigid board polystyrene panels are easy to install and offer an insulating value of R12 (2” thickness) or R16 (3” thickness).
Door Finishing Options
Read More
We offer a variety of door finishing options, including polycarbonate sheeting (which allows plenty of natural light into the building) and Tuff Rib cladding in a variety of colours. Mix and match finishing choices to match or complement each building style.
The Self Supporting Header
Read More
This option is typically used in retrofit applications where the building is not strong enough to support the weight of the door or where the door must extend past the roofline of the building. For easy installation, we include all necessary hardware and finishing.
The Pedestrian Door Package
Read More
Pedestrian doors are a great option for easier foot access into the building - especially on doors that cover the entire face of the building. They are fully insulated and come pre-installed from factory.

Our steel buildings provide a cost-effective solution to create low-maintenance, customizeD space that is safe and secure.
