Preparing CAD Details for a Custom Casement Door

For a custom casement door, submit a dimensioned CAD drawing that clearly shows the door’s frame and sash, opening direction, glazing rebate, insulation, mesh selection, drainage, and sealing requirements. Xinhe Aluminium’s published casement-window specifications may offer a point of reference, but they are not door specifications. Ask the technical team to confirm the required door dimensions and drawing details before production.

What to Include in Your CAD Submission

Make the drawing easy to review by labeling every dimension and unit. Distinguish the outer frame from the sash, identify the glazing rebate and interfaces, and add a cross-section for any non-standard profile. Specify the opening direction and whether you require diamond mesh or high-transparency mesh.

Where relevant, indicate how the design should accommodate hidden drainage, multi-layer weatherproof seals, and integrated safety safeguards. Mark these as requested features, and show their interfaces where possible. Confirm with the supplier how each feature can be incorporated into a casement door.

Use Window Data as a Reference—Not a Door Specification

The available product information describes a casement window with a listed thickness of 1.8 mm, an outer frame measuring 120 mm by 30 mm, a sash measuring 63.5 mm by 75 mm, and a 38 mm glazing rebate. It also gives insulating strip widths of 35.3 mm for the frame and 22 mm for the sash, along with a material figure of 10.7 kg/m².

These measurements belong to the referenced window product and should not be copied into a custom door design without approval. Provide the door’s own frame, sash, glazing, and insulation requirements, then request technical confirmation.

Custom Profiles and Manufacturing Checks

If the door needs a special cross-section, show its shape and dimensions in the CAD file and ask the supplier to assess manufacturability and any further information needed. A listed project case mentions custom mold opening for special profiles, including shaped, narrow-frame, and large-section curtain wall profiles. It does not establish specific requirements for casement-door profiles.

Guangdong Xinhe Aluminium Co., Ltd. describes its business as the research, development, and production of building, decorative, and industrial aluminium profiles. The company lists aluminium casement doors among its application areas, but the available information does not include a door-specific CAD template.

Reference Data and How to Apply It

Frequently Asked Questions

Can the listed window measurements be used for a custom casement door?

Not without confirmation. The published figures apply to a casement window; request door-specific dimensions for the frame, sash, glazing, and insulation.

Which functional details should I mark on the drawing?

Identify any requirements for hidden drainage, multi-layer weatherproof sealing, and integrated safety safeguards. Show relevant interfaces where the drawing allows.

Do the listed minimum order and lead time apply to doors?

The casement-window listing gives a minimum order quantity of 500 square metres and a delivery time of 15–20 days. These terms are stated for that product, so confirm whether they also apply to a custom door.

Before You Send the Drawing

Prepare a dimensioned CAD file showing the door’s frame and sash geometry, opening direction, glazing and mesh choices, and requested drainage, sealing, and safety features. Clearly identify any custom sections. Before moving forward, confirm door-specific parameters, production feasibility, minimum order quantity, and schedule with the supplier.
