Custom cover enquiries: what should a clear drawing include?

Specify dimensions, materials, loads and markings early for clearer technical discussions.

Define structure and dimensions

Provide overall size, clear opening, frame height, installation method and tolerances. Include site photographs and existing product drawings when available.

Describe functional requirements

Confirm load performance, anti-theft features, sealing, noise reduction, opening and markings individually. Include environmental conditions and project specifications for unusual applications.

Confirm samples and production batches

Include expected quantity, packing, delivery location and target dates. Agree on approval procedures for samples and production batches at the start of the project.
