Dimensions describe inside-frame openings, not shipping sizes or building cutouts. Packing dimensions and electrical details are established for the selected configuration.
Hermetic door size, finish, operation, packing and documentation can be customized for the destination project and its installation requirements.
Buying hermetic doors from China requires a clear handover between the supplied assembly and the destination site. shengtongjh coordinates equipment and material supply around the agreed drawing, component package and installation requirements.
Translate measurement definitions before translating the order
A buyer may describe a door by its net passage, while a site drawing gives the building opening and a supplier drawing gives the inside of the frame. These dimensions can be close enough to look interchangeable while requiring different leaf and frame sizes.
Identify each measurement on the same drawing and keep the units visible. Show the finished floor datum, wall thickness, operator side and opening direction. A photograph supports the information, but perspective in a photograph cannot establish the dimensions needed for fabrication.
For an existing building, measure the interface after the relevant finishes are known. Ordering before a floor buildup or wall lining is decided can leave the frame in the wrong position for its seal.
Agree what crosses the shipment boundary
A complete assembly and a component kit create different responsibilities at the destination. The buyer needs to know which parts arrive together and which must be provided, assembled or adjusted locally.
List the frame sections, leaf, seals, rail, guides and fixings included in the package. For an automatic version, identify the operator, activation devices, protective detection, locks and any interface accessories. Avoid a generic description such as full set where it hides these details.
Connect each package to the relevant door reference. A project with several similar openings benefits from clear component identification so frames, trims and handing-specific parts are not mixed during storage or installation.
Match electrical requirements to the destination
Do not assume that the supply voltage and frequency used in the production location are suitable at the destination. The selected operator and accessories must be coordinated with the site's power and control arrangements.
Identify the purpose and type of each external connection. Access readers, room controls and alarm systems may use different signal interfaces. Resolve these connections before dispatch so installation does not depend on improvised wiring or unsupported controller changes.
Match documentation to the actual configuration
The destination project may require particular evidence, drawings or installation information. Agree that scope before the order is finalized. A general company document or a report for another door construction does not establish the performance of the supplied assembly.
Keep the required air-leakage duty separate from any fire, acoustic, smoke or shielding requirement. If the configuration changes, review which evidence still applies rather than leaving an earlier report attached to a different door.
Protect the components that determine fit and sealing
Long rails and slender frame members need support during handling. Finished leaves need protection against distortion and face damage, while seals should not be held in an unintended compressed shape by the packing.
Agree package identification and handling information with the shipment scope. Actual shipping dimensions and weights come from the selected construction and packing, not from the doorway size. Local unloading and internal movement should be planned before delivery reaches the site.
Complete the handover with local installation
The destination team needs approved drawings, component identification and instructions for the selected assembly. Site preparation includes the supporting structure, finished floor and wall interfaces, plus power and control provisions for automatic operation.
Receipt of the goods is different from acceptance of the installed door. Alignment, travel, sealing and the required operating functions must be checked after installation. Any site changes should be recorded so future replacement parts match the door that was actually handed over.
