How do contractors buy bi-fold and accordion patio doors wholesale?

Contractors buy bi-fold and accordion patio doors wholesale by opening a trade account directly with Gladiator Window & Doors, bypassing distributors and showrooms to access factory-direct pricing on every unit. Once your account is approved through our Reseller & Wholesale Application, you receive a dedicated trade pricing schedule, priority quoting, and a single point of contact for all your orders — whether that's one door on a custom home or a 40-unit multi-family project.

The wholesale buying path works like this:

• Apply for a trade account — submit your contractor license number, business entity, and a brief description of your typical project types.
• Receive a trade pricing schedule — pricing is tiered based on annual volume and project size, not arbitrary minimums.
• Submit project specs — rough opening dimensions, panel count, finish, glass spec, and hardware preference submitted per project.
• Get a formal quote within 48 hours — your account rep reviews the spec sheet and returns a line-item quote you can plug directly into your bid.
• Confirm order and deposit — standard deposit to release production on custom-sized units; in-stock standard sizes move faster (see lead times below).

Free nationwide shipping is included on all orders — no freight surprises buried in the final invoice.

What is the ordering process for factory-direct folding patio doors at scale?

The factory-direct ordering process for folding patio doors at scale runs through a structured spec-and-quote workflow designed for multi-door projects, with one account rep managing the entire order from submittal to delivery. Here is the full sequence contractors and developers follow:

1. Project intake form — submit door count, rough opening schedule (width × height per opening), configuration (2-, 3-, 4-, 6-, or 8-panel), swing direction, finish, and glazing spec.
2. Engineering review — our team checks header requirements, panel weight per leaf, and threshold/track options against your structural notes.
3. Formal shop drawing or submittal package — provided at no charge for projects of five or more openings; available for smaller projects on request.
4. Order confirmation & deposit — 50% deposit locks production scheduling; balance due prior to shipment.
5. Production & quality check — each unit is inspected before crating.
6. Freight scheduling — LTL or full truckload coordinated with your site super; we provide tracking and ETA updates directly to your project manager.

Developers running multiple units on a single project should ask about staged delivery scheduling — we can hold finished product in our Florida or California warehouses and release by building phase to reduce on-site storage risk.

What lead times should builders expect when ordering bi-fold doors direct from the manufacturer?

Lead times for factory-direct aluminum bi-fold doors range from same-week ship (in-stock standard sizes) to 8–12 weeks for fully custom configurations — the specific timeline depends on panel count, rough opening size, finish, and glazing spec.

Here is a practical lead-time breakdown for 2026 project planning:

• In-stock standard sizes — 2- to 4-panel configurations in common widths and matte black finish typically ship within 1–5 business days from our stocked inventory. See in-stock doors ready to ship.
• Standard-spec custom sizes — thermal-break aluminum, 6mm tempered glass, standard finishes (matte black, dark grey RAL 7016, white RAL 9010, bronze anodized): 4–6 weeks.
• Large-span or high-panel-count units — 6- to 8-panel systems, oversized rough openings (up to 32 ft wide), or non-standard glass specs: 8–12 weeks.
• Multi-project bulk orders — phased production scheduling available; first phase typically ships within the standard custom window; subsequent phases staggered per your site schedule.

Builder tip: For projects with hard completion dates, order against in-stock inventory wherever the rough opening allows, and reserve custom-span units for signature openings. Mixing in-stock and custom on the same project is a proven schedule-compression tactic.

How do dealers set up a wholesale account for aluminum bi-fold and folding door systems?

Dealers set up a wholesale account by completing the Gladiator Reseller & Wholesale Application online — approval typically takes one to two business days, and your trade pricing is active immediately upon approval. The application asks for:

• Business name, entity type, and state of operation
• Contractor license or dealer/reseller certificate number
• Estimated annual door volume (used to tier your pricing schedule)
• Primary product categories of interest (bi-fold, sliding, pivot, storefront, or windows)
• Key contact for quotes and order management

Once approved, dealers receive a dedicated account rep, access to our full product catalog with trade pricing, and co-marketing support including product imagery and spec sheets for client presentations. Dealers who resell to builders and homeowners can mark up freely — our pricing model is designed to protect your margin while keeping the end price competitive with dealer-network brands that carry two or three markup layers.

Looking to add complementary products? Our sliding glass door collection and architectural pivot doors carry the same wholesale pricing structure and can be bundled on a single project order.

What minimum order quantities or project sizes qualify for contractor pricing on accordion patio doors?

There is no hard minimum order quantity — contractor and dealer pricing activates at account approval, not at a unit threshold — but volume tiers reward larger and repeat orders with progressively better net pricing. Here is how the structure works in practice:

• Tier 1 (1–4 units/year): Approved trade pricing on all orders, free shipping, standard 48-hour quote turnaround.
• Tier 2 (5–19 units/year): Enhanced discount off trade pricing, priority production scheduling, dedicated account rep.
• Tier 3 (20+ units/year or single multi-unit project): Best-net pricing, staged delivery coordination, submittal package support, and volume-based payment terms available.

A "unit" in the context of accordion patio doors is counted per opening (one rough opening = one unit), regardless of panel count. A six-panel folding wall filling a 24-foot opening counts as one unit. Developers with large multi-family or hospitality projects should discuss project-level pricing — a 40-opening hospitality project, for example, is quoted as a package, not 40 individual line items.

What specs and construction details do contractors need to submit when ordering large bi-fold doors?

Contractors ordering large bi-fold or accordion patio door systems need to submit rough opening dimensions, panel configuration, swing/stack direction, sill type, finish, and glazing spec — the more complete the submittal, the faster the quote and the fewer field surprises at installation. Use this checklist for every opening:

• Rough opening width and height (in inches, to 1/8-inch precision)
• Panel count and configuration — 2, 3, 4, 5, 6, or 8 panels; folding direction (all-fold left, all-fold right, center-open split)
• Stack side — which side the folded panel stack lands on; critical for furniture and traffic planning
• Threshold/sill type — low-profile flush track (ADA-friendly, most residential), recessed track, or raised threshold
• Frame finish — matte black, dark grey RAL 7016, white RAL 9010, or bronze anodized; interior/exterior finish can differ
• Glass spec — standard is 6mm tempered; specify low-e coating, tint, or laminate if required by project
• Swing direction — inswing or outswing (outswing is standard on most configurations)
• Header and structural notes — lintel/beam size, header depth available, and whether the opening is load-bearing
• Hardware and locking — multi-point locking system preference, handle finish, keyed or non-keyed

Header and Rough-Opening Planning Notes for Large Spans

Bi-fold systems spanning more than 16 feet require careful header planning. As a general rule:

• Rough openings wider than 16 ft typically require an engineered steel or LVL beam — confirm with your structural engineer of record.
• Allow a minimum of 2–3 inches of header depth clearance above the door unit for the top track and hardware carrier.
• Slab-to-slab or slab-to-beam rough opening height should account for the track assembly height; our submittals specify exact dimensions per unit.
• For flush-track (low-profile) sill on concrete slabs, plan for a recess poured into the slab — dimensions included in the shop drawing package.
• Stack pocket width (where the folded panels land) should be a minimum of 10–12% of the total door width per stack side.

Need a folding pass-through window above a counter or bar opening? Our folding passthrough windows follow the same ordering process and can be bundled with bi-fold door orders on the same project.
