Manufacturing Focus

Custom doors

Wrought iron doors, French doors, oversized entry doors, pivot doors and Dutch doors are presented as made-to-order reference designs.

Architectural metalwork

The public product range also includes iron railings, fences, stair railings, windows, gazebos, steel-structure pergolas and related custom metalwork.

Drawing-based production

Opening dimensions, structure, glass, hardware, finish, installation conditions and delivery scope are reviewed against the project brief and approved shop drawings.

Factory role

The company presents itself as a manufacturer and project supplier. Local installation responsibility, site conditions and destination-country compliance remain project-specific.

Common Material and Glass References

Q235 carbon steel

We primarily use Q235 carbon steel for custom iron doors and architectural metalwork. Final steel grade, thickness, structure and surface treatment are confirmed according to approved shop drawings and project requirements.

5 mm + 9A + 5 mm insulated glass

Our commonly used insulated glass configuration is 5 mm glass + 9 mm sealed air space + 5 mm glass, with a nominal overall thickness of approximately 19 mm. Glass type, safety treatment, privacy level, coating and final thickness are confirmed per project.

Q235 and 5 mm + 9A + 5 mm are common manufacturing references, not fixed specifications for every product or order. No tempered, laminated, Low-E, argon-filled, fire-rated, acoustic, impact or code-compliance claim is made here without product-specific evidence.
