What types of warehouse doors are available (dock-high vs. grade-level)?
TruSteel offers two main warehouse door setups: dock-high overhead doors that sit about 48 in. above the paving for tractor-trailer loading, and grade-level (drive-in) doors that start flush with the slab so forklifts and box trucks roll straight inside. Both can be roll-up or sectional and are framed where you need them.
Start with how you load. Dock-high doors sit 48–52 in. above the paving—the same level as a semi-trailer floor. We frame these openings 8′–10′ wide by 9′–10′ tall and reinforce them for dock levelers, seals, and bumpers. On a commercial steel warehouse, this layout keeps forklifts on the platform and speeds pallet flow.
Grade-level (drive-in) doors start flush with the slab. Typical clearances are 12′×14′, 14′×16′, or larger so box trucks or skid-steer loaders can roll straight inside. They can be insulated roll-up curtains or sectional overhead panels and can include windows for daylight.
Most customers blend both: a line of dock-high doors for shipping and one or two grade-level doors on the gable end for equipment or maintenance vehicles. Every TruSteel red iron, bolt-up steel building kit arrives pre-cut with your framed openings in place—no field torching. County-specific stamped building and foundation plans detail the door loads for quicker permits.
