Custom Doors & Prehung Systems for Canada
China-manufactured interior doors, entrance doors and prehung sets for Canadian importers, contractors and project buyers, with inch dimensions, handing and packing reviewed before production.
SJ DOORS supplies custom doors and prehung door sets from China for Canadian projects. Orders can be quoted in inch or metric dimensions, with frame, hinge, locking, handing, finish and hardware requirements checked on the approved schedule. Window and fire-door certification documents are confirmed per model and system.
Interior, entrance and project door sets.
Canadian projects may combine solid-core interior doors, entrance doors and prehung sets in the same shipment. We review the opening schedule and finish direction together so the doors, frames and hardware are produced as one coordinated package.
- Solid-core MDF, timber, aluminum and steel door options
- Door slabs, prehung sets, frames and architraves
- Inch or metric opening sizes with custom heights
- Left-hand and right-hand handing reviewed on the drawing

Inch sizes and site conditions must be checked together.
Opening size
Provide the rough opening or finished opening, wall type and finished floor thickness before the frame is confirmed.
Handing and swing
Each opening should identify the hinge side, swing direction and any special condition such as a closet or corridor return.
Hardware
Locks, handles, hinges and closers are checked against the door type, backset, preparation and fire or security requirement.
Certification scope is confirmed by product.
CSA A440 and NAFS documentation can be reviewed for applicable window systems, while UL listed assemblies are available for applicable fire doors. Door finish, core, frame, hardware and glass scope are confirmed on the quotation and approved drawing. We do not state that every door in an order carries the same certification.
For Canadian projects, the importer and local professional should confirm the applicable building, fire, accessibility and installation requirements before production. We provide the available model-specific documents needed for that review.
Protect finished doors before container loading.
Door protection
Face protection, corner protection, hardware separation and clear opening labels help reduce handling damage and site confusion.
Shipment planning
Carton dimensions, wooden-crate requirements, loading sequence and destination port are reviewed with the quantity and delivery schedule.
Questions before requesting a quotation.
Do you supply custom doors and prehung door sets to Canada?
Yes. We supply interior and entrance door systems from China for Canadian importers, contractors, developers and project buyers. We do not claim a local factory or Canadian stock.
Can you produce doors in inch dimensions and custom heights?
Yes. Opening sizes can be provided in inches or millimetres. Width, height, frame details and wall conditions are converted and checked on the approved shop drawing before production.
Do you supply slabs, prehung doors or complete sets?
Door slabs and prehung sets can be reviewed with frames, hinges, locking preparation and hardware according to the approved door schedule.
Can you confirm left-hand and right-hand opening?
Yes. Handing and swing direction must be shown on the opening schedule or drawing. The approved handing is checked before production so the door opens correctly on site.
What hardware can be included?
Hinges, locks, handles, closers and project-specific hardware can be coordinated. The final hardware scope depends on the door type, fire rating and security requirement.
Which certification documents are available?
Documentation is product-specific. CSA A440 and NAFS can be reviewed for applicable window systems, and UL listed assemblies are available for applicable fire doors. Exact door and window certificate scope is confirmed by model before quotation.
