Door projects rarely arrive with exactly the same requirements.

Two openings may have similar dimensions but require completely different solutions because of the surrounding wall structure, available headroom, operating frequency, environmental conditions or control requirements.

Huadun has therefore continued to develop its project-based manufacturing and technical support process for overseas customers.

Before production, the team can review information such as opening width and height, installation position, available side room and headroom, quantity, operating method and electrical requirements.

For more complex projects, architectural drawings, door schedules and site photographs can also be reviewed before the final configuration is confirmed.

Customization may include door dimensions, materials, surface finishes, operating systems, control methods, accessories and selected packaging requirements.

Electrical configurations can also be discussed according to the voltage and frequency used in the destination market.

This process is particularly important for fire protection products. Fire curtains, smoke curtains and fire shutters may involve additional project requirements such as installation space, fire alarm linkage and required fire-resistance performance.

Rather than applying one standard configuration to every project, Huadun recommends confirming the actual site conditions before final quotation and production.

The same approach is used for industrial sectional doors, garage doors, high speed doors and roll up doors where traffic frequency, insulation, security, wind conditions and installation method may affect product selection.

Customers who already have technical drawings can send them directly for review. When complete drawings are not available, opening dimensions and site photographs are usually a useful starting point.
