From glass storefronts to industrial overhead doors — we work on all commercial door types found in Minnesota businesses.
Full steel construction with reinforced frames. Ideal for high-risk areas like storage rooms and back entrances. Resistant to cutting, prying, and impact.
Galvanized steel sheets over a honeycomb core. Common in office buildings and schools. Can be fire-rated and paired with security locksets.
Tempered or laminated glass in aluminum frames. Offers visibility and security. Often used in retail stores and lobbies across Minnesota.
Heavy-duty mesh or metal bars that allow airflow while deterring break-ins. Popular for warehouses, loading docks, and service entrances.
Preparing Minnesota commercial doors for harsh seasonal conditions
Minnesota winters put extreme stress on doors. Temperature swings cause metal to contract and expand, leading to gaps, sticking, and seal failure. Our security doors are installed with thermal breaks and weatherstripping rated for -40°F to prevent drafts and ice buildup.
Spring thaw can reveal warped frames or frozen locks. We recommend an annual inspection before winter and after spring. DJ Commercial Door offers seasonal maintenance to keep your doors operating smoothly through Minnesota's toughest months.
Tip: Schedule a pre-winter door inspection in Minnesota before temperatures drop — closers and seals need adjustment to perform through subzero conditions.
Don't wait for a door failure to disrupt your business — watch for these common warning signs.
Misalignment can be a security risk. If your door sticks, drags, or won't latch, it may indicate settling or worn hinges. Call us before the problem worsens.
Gaps between the door and frame allow forced entry and energy loss. This is common in older Minnesota buildings. A new security door eliminates these weak points.
Moisture and road salt accelerate corrosion. If hinges or locks show rust, their strength is compromised. Replace them before a break-in occurs.
Drafty doors let conditioned air escape. In Minnesota, that means higher energy costs. Upgrading to a well-sealed security door improves efficiency and comfort.
