Every project inquiry receives a written response within 6 business hours — including a structural feasibility assessment, system recommendation, and defined next steps. No verbal approvals. No ambiguous timelines.
Every response is structured — not a generic acknowledgement. The 6-hour window is the outer limit, not the target average.
Based on your submitted drawings or project brief, we assess whether the described system is structurally achievable, identify any geometry constraints, and flag any parameters that require clarification before proceeding.
We recommend a specific mesh system type (woven, rigid panel, coil, flexible fabric) with initial material grade and surface treatment options appropriate for your application environment — not a catalogue guess.
We provide indicative lead time ranges for both sample development and production, scoped to your project type. Standard, custom, and urgent paths are identified where applicable.
Every response closes with a specific list of next actions required to advance the project — whether that is drawing confirmation, specification detail, or sample approval. The process does not continue without completing each step.
Architectural and structural drawings submitted via the online form, email, or file transfer. Includes DWG, PDF, DXF, and image formats. Response includes feasibility notes and system definition questions.
Questions about material grade selection, surface treatment options, wire diameter, aperture sizing, open area percentage, and edge treatment. Each query receives a written specification note.
Requests to begin the sample development process. The response includes confirmation of receipt, sample parameters to be confirmed, and the sample approval process timeline before production begins.
Project briefs or concept-stage descriptions without formal drawings. The response assesses what information is needed to define the system and what level of preliminary recommendation can be offered.
Updates, change requests, and production queries for projects already in progress. Status communications are issued at each project milestone — drawing confirmation, sample approval, production start, and shipping.
Post-delivery questions, installation coordination notes, and issue reports. Every problem report is acknowledged in writing and progressed to a resolution path — not left open-ended.
JBL Metal does not issue or accept verbal confirmations for any stage of a project. This is not a procedural formality — it is a structural risk control that protects both parties.
Verbal agreements create ambiguity about specification parameters, delivery conditions, and quality expectations. Eliminating them removes the most common cause of project disputes between manufacturers and project teams.
All drawing parameters must be confirmed in writing before the sample development stage begins. No sample is produced against verbal drawing approval.
Production does not begin until a written sample approval is received. Samples shipped and approved via email constitute the production reference. No phone or meeting approvals accepted.
Any change to specification, quantity, or delivery condition after initial approval must be submitted in writing. Changes communicated verbally are not processed until documented.
