External screen
For a commercial façade, mark panel dimensions, joint widths and bracket interfaces. Ask the design team to confirm support spacing and loads; the quoted sheet thickness is not a complete structural specification.
Application to purchasing requirements
Perforated metal cladding for defined project conditions
Begin with the elevation, exposure and support interface. We help buyers organize application requirements into an enquiry; project suitability and installed-system performance still need design review and appropriate documentation.

Four settings, different acceptance questions
Interior feature wall
For a lobby wall, specify the visible face, alignment at joints and protected edges. If sound absorption is required, request evidence for the backing, cavity and fixing arrangement as a complete assembly.
Service enclosure
For screened plant areas, show access zones, clearances and corrosion exposure. Describe airflow criteria separately; open area identifies geometry but does not by itself verify enclosure ventilation.
Repeated elevation bays
For repeated bays, identify the reference panel, pattern direction and delivery sequence. Separate replacement pieces and corner conditions so the factory can price distinct fabrication operations and label packs accordingly.
Resolve application trade-offs before selecting an offer
Does greater open area mean the panel is a better choice?
More openings may support a lighter visual screen, but remaining ligaments, edge zones and the support design still matter. A denser pattern may offer a different appearance and rigidity. Record the required visual effect and have the project team review geometry, thickness and attachment together rather than buying on open area alone.
Should a lower-cost metal substitute be accepted?
Compare grade, exposure, coating process and maintenance access alongside price. An economical alternative may fit an interior decorative brief while exterior exposure can require a different finish and material selection. Ask the supplier to identify the substitution, then obtain the buyer's technical approval before comparing the revised total.
What does the sample prove?
A sample can document hole geometry, edge quality and appearance under agreed lighting. It does not establish fire rating, wind resistance or acoustic absorption. Request the applicable report for the exact system if those requirements form part of the project specification.
Which delivery constraints belong on the RFQ?
Provide the US receiving location, unloading limitations, maximum pack size and intended installation sequence. Clarify whether protective film, interleaving and panel labels are included. Compare delivered costs only after freight and site handling assumptions use the same scope.
Send the elevation and the open questions
Identify the installation setting, panel schedule and required documents. We will use those inputs to frame a supplier comparison, with deviations clearly separated.
