Key Features

Key Features Built For Commercial Door Schedules

Commercial projects succeed when openings are specified correctly and arrive jobsite-ready. These features focus on durability, code coordination, and procurement efficiency for contractors and distributors.

SDI Level 1-3 Configurations

Commercial projects fail when doors are underbuilt for the opening. Euwoo offers SDI Level 1, Level 2, and Level 3 configurations so you can specify the right balance of durability, weight, and cost for each location. Level 1 is a practical fit for low-frequency interior openings, while Level 2 covers most corridors and everyday tenant improvements. For high-abuse areas like loading routes, schools, and hospitals, Level 3 adds heavier skins and reinforcement.

Coordinated Door, Frame, and Hardware Packages

Ordering doors, frames, and hardware from separate sources often creates tolerance issues and missed handoffs. As a commercial steel door supplier focused on B2B projects, Euwoo can deliver coordinated packages with preps aligned to your chosen lock, closer, hinges, and exit devices. This reduces field drilling, improves consistency across openings, and helps installers keep labor predictable.

Fire-Rated and Smoke-Control Ready Options

Many commercial buildings require corridor and stair openings to meet fire and life-safety codes. We offer steel door systems that can be configured as fire-rated assemblies, including options up to 3 hours where required. Our team reviews your rating requirements and application to propose a build that supports labeled configurations and jobsite inspection.

Finish and Corrosion Protection Choices

Finishes affect both the look and lifecycle cost of a commercial building steel door. For office and retail environments, we provide a smooth factory primer ready for field paint, or durable powder-coat colors. For humid, coastal, or wash-down areas, galvanized skins and corrosion-resistant prep options help reduce rusting around edges and hardware cutouts.

Vision Lites, Louvers, and Access Control Preparation

A modern office steel door often needs to do more than swing and latch. Euwoo supports vision lite cutouts for safety sightlines, conference-room visibility, and code-driven glazing requirements, plus louver options for mechanical closets and IT rooms. For controlled areas, we can prepare doors for access control systems, including electrified lock preps and raceways.

Acoustic and Thermal Core Options

Noise and temperature control are common pain points in commercial interiors. By selecting the right core and perimeter sealing strategy, our doors can improve acoustic privacy for executive offices, meeting rooms, and healthcare consultation spaces, while also helping limit air transfer between conditioned and unconditioned zones.

Quick-Ship and Technical Support

Project schedules rarely wait for long lead times. Euwoo maintains a quick-ship program for common sizes and standard configurations. When the job requires non-standard dimensions or special preps, our engineering support keeps the process moving with clear shop drawings, cut sheets, and packaging instructions.

Applications

Applications

Commercial openings vary by traffic, security, and code requirements. These are common scenarios where steel door systems provide long lifecycle value.

Office Tenant Improvements

Steel doors for corridors and suite entries that stay aligned and latch cleanly over years of use. Vision lites improve safety at intersections.

Retail Back-of-House

Durable doors for stockrooms and receiving areas that resist dents from hand trucks and support security hardware.

Stairwells & Egress Routes

Code-compliant openings for stair enclosures and shaft applications with proper rating, gasketing, and hardware.

Institutional Spaces

Schools, clinics, and public buildings need openings that handle constant use and frequent cleaning with minimal maintenance.

Materials

Material and Finish Options

Select materials and finishes based on the opening environment, desired appearance, and maintenance expectations.

Steel Options

Cold-Rolled Steel

Best for: Standard interior commercial applications

Common choice for cost-effective commercial openings with factory primer.

Galvanized Steel

Installation

Installation Guidance (Contractor-Focused)

Proper installation protects door performance and reduces punch-list issues. Always follow local codes and manufacturer instructions.

1

Confirm Opening Conditions

Verify rough opening dimensions, plumb/level, wall construction type, and frame throat selection.

2

Set and Anchor Frames

Use anchors appropriate to wall type. Shim for plumb and square, secure at hinge and strike areas.

3

Maintain Clearances

Check consistent reveals at head and jambs. Confirm floor conditions match threshold selections.

4

Install Hardware

Use specified hardware set. Follow manufacturer templates and torque guidance.

5

Final Adjustments

Adjust closers, verify latch engagement, document deviations, keep touch-up guidance.

Common Mistakes to Avoid

  • Setting frames out of plumb or out of square
  • Field drilling without confirming hardware set list
  • Modifying rated openings without approval
FAQ

Frequently Asked Questions

Start with the opening location and expected abuse. Level 1 for low-frequency interior doors, Level 2 for most corridors and tenant entries, Level 3 for high-traffic or high-abuse areas. Map each opening to traffic, security, and code requirements.

Gauges are selected based on duty level and denting risk. Lighter gauge for low-traffic interiors, heavier gauge for corridors and service routes. Tie gauge selection to SDI performance level and hardware being applied.

Yes, fire-rated configurations are available. A compliant fire opening is a system: door leaf, frame profile, core type, edge details, gasketing, and hardware must all match. Share your rating requirement and hardware schedule.

We supply door slabs, frames, or complete prehung assemblies. Prehung sets save labor on new construction because door, frame, and hinging are aligned at the factory.

Yes. We align door and frame preps to your schedule, including cylindrical/mortise locks, exit devices, closers, hinges, and electrified hardware. Provide hardware set list for prep coordination.

Standard sizes and common configurations can often be supplied through quick-ship programs. Made-to-order doors with special dimensions or complex preps take longer. Share your target ship date and we'll propose a mix of quick-ship and customized builds.
