Aluminum Storefront Doors for Commercial Projects

Bring the door, frame, glass and hardware into one coordinated opening. Share your door schedule with DERCHI to discuss configuration and supply scope.

New openings & replacementDoor schedule firstProject-specific scope

01 / Define the opening

Choose your storefront entrance layout

Start with how people enter, then identify what belongs in the supply package.

A layout defines the opening. The selected series, glazing and hardware define the final assembly.

Single framed glass entrance with sidelights and a transom

01Single door

Review clear passage, swing space and daily access. Record any sidelight or transom as part of the opening.

02Paired doors

Decide which leaf operates each day and when both open. Coordinate meeting stiles, locking and closing sequence.

03Door + fixed glazing

Coordinate frame depth, head and jamb connections, glass support and the threshold across the whole frontage.

Define the supply scope separately.

02 / Stile & system selection

Choose the frame around the hardware

The stile is the door's vertical edge. Compare its width with the exact lock, exit-device and glazing requirements.

Narrow

Prioritize sightlines; check hardware space, templates and glass clearance before selection.

Medium

Review the balance of visible frame and hardware space against door size and weight.

Wide

Allow for specified hardware and rail requirements. Stile width alone does not establish commercial duty.

Thermal or non-thermal? Use exposure and energy requirements to set the shortlist. Compare whole-door data for the selected glass, frame and threshold.

Keep stile width, frame depth and profile wall thickness separate in the specification.

03 / Dimensions & frame fit

Four dimensions. One coordinated opening.

Opening size, finished frame, door leaf and clear passage are different measurements. Mark each one on the elevation.

Site opening widthFinished frame widthDoor leafOpening height
Concept elevation · Measure clear passage with the door open, allowing for the leaf and stops.
  • New construction: record opening width/height, finished-floor level, substrate and adjacent glazing.
  • Existing frame: send section photos, dimensions, condition and current hinge/lock positions before choosing a replacement leaf.
  • Handing: show swing direction and the viewing convention; identify active and inactive leaves for a pair.
  • Installation interface: assign anchors, movement allowances, perimeter seals and drainage to the agreed system detail.

Measure clear passage with the door open, from the leaf face to the opposing stop. Use the applicable access requirements to review it; nominal leaf width alone is insufficient.

04 / Hardware, access & egress

Plan how the door opens, closes and locks

Public hours, closed hours and emergency exit can require different operating arrangements. Resolve them before machining the frame and leaf.

Hanging & closing

Match suspension, reinforcement and closer selection to leaf size, weight and expected use.

Locking & exit devices

Specify make/model and template. Check stile space, backset, glass setback and any mullion.

Paired-door operation

Identify active/inactive leaves, meeting details and the required closing and latching sequence.

Access control

Coordinate the locking interface, power transfer and exit operation with the project hardware specialist.

For high-use entrances, review applicable whole-assembly and hardware test evidence. Recheck compatibility when components change.

05 / Glass, finish & exposure

Match the glazing to the opening's conditions

Safety treatment, insulating makeup and surface finish do different jobs. Select them together with the frame, hardware and threshold.

Safety & use

Identify the required safety-glazing specification. Glass weight and thickness also affect the leaf and hardware.

Thermal & solar needs

Compare whole-door U-factor and solar data where required; glass-only values describe a different scope.

Sightlines & privacy

Balance visibility, solar control and privacy. Check the actual sample and intended viewing conditions.

Weather exposure

Coordinate seals, threshold and drainage. Review air, water and structural data for the specified assembly.

Finish selection: use a physical sample to agree color and texture. Confirm the coating specification and maintenance for the selected system, especially at coastal sites.

Impact resistance and fire performance require the applicable system evidence; a glass choice alone does not establish either.

06 / Project documents

Review files for the actual configuration

Use your door schedule and specification to identify the documents needed for the selected series and project location.

08 / A quote you can compare

Use one opening ID from drawing to delivery

When comparing aluminum storefront door manufacturers, ask each to quote the same assembly, responsibilities and destination.

Scope example · Opening D01Door and frame · Glass: factory or site glazing · Hardware: supplied, fitted or by others · Drawing revision · Packing and delivery terms.

Agree each line before production, including the items supplied by others.

  1. Prepare the opening brief

    Country/city, opening IDs, quantities, elevation, measured dimensions, layout and required arrival date.

  2. Agree the supply package

    Glass and hardware, assembled or knockdown supply, machining, documents, samples, packing, trade terms and installation exclusions.

  3. Define approval and handover

    Drawing revision and release point, shipping milestones, receipt checks, installation responsibility and operating handover.

09 / After handover

Plan service and spare parts with the order

Keep the final drawings, opening IDs and fitted hardware references for maintenance and replacement parts. Discuss DERCHI's 10-year warranty terms for the selected system, including covered components, exclusions, claim procedure and labor or freight responsibilities.
