Quality &
Verification

The SGS Salt Spray Test independently verifies that JBL Metal stainless steel mesh surface treatments meet defined corrosion resistance thresholds under salt spray exposure. The test exposes metal samples to a continuous 5% sodium chloride mist at 35°C — simulating coastal and chloride-rich environments in accelerated time. SGS is the world's largest inspection and certification body, operating in 140 countries. The certification is a third-party result, not a self-declaration. It can be referenced in project specifications and procurement documentation for coastal, exterior, and high-humidity architectural applications.

JBL Metal follows a six-stage production quality inspection process: (1) Raw material incoming inspection — wire diameter and mill certificate verification; (2) Weaving process patrol — tension and aperture uniformity monitoring; (3) Sample confirmation inspection — physical sample measured against drawing spec, client written approval required; (4) First-piece production inspection — first batch unit verified against approved sample before batch proceeds; (5) Pre-dispatch full inspection — dimensional re-measurement, 100% visual inspection, quantity count; (6) Pre-shipment video confirmation — complete inspection video sent to client, shipment held until written approval received. Each stage is documented. No stage proceeds without the previous stage being cleared.

Yes. JBL Metal provides complete raw material mill certificates on request for all orders. The mill certificate documents the chemical composition (Cr, Ni, Mo, C, Mn), mechanical properties (tensile strength, yield, elongation), heat/batch number, and wire diameter of the stainless steel used in your production run. This provides full traceability from the finished mesh panel back to the source material batch — relevant for structural applications, export compliance, and OEM equipment certification documentation. Advise at order confirmation that a mill certificate is required.

Before every shipment is dispatched, a complete inspection video is recorded and sent to the client via WhatsApp or email. The video covers: unpacked finished goods showing surface condition and dimensional compliance, edge treatment close-up review, quantity count on camera, packing method demonstration, and carton labelling confirmation. You review the video and send written confirmation before goods are released. If you identify any concern, the shipment is held and the issue is resolved first. This process gives you direct visibility of the physical goods before they leave the factory — eliminating the most common source of site delivery disputes.

Yes. JBL Metal fully supports third-party pre-shipment inspection. If your project requires an independent inspection report from SGS, Bureau Veritas, Intertek, or another accredited inspection body, this is arranged on request. Please advise at order confirmation so the inspection can be coordinated against the production schedule. JBL Metal does not charge a coordination fee — the inspection fee is charged by the inspection body directly. For projects where third-party inspection is a procurement requirement, advise at drawing submission stage so it can be factored into the project timeline.

Standard documentation with every shipment: commercial invoice, packing list, bill of lading or air waybill, and certificate of origin. Available on request or as required: raw material mill certificate (provided as standard on request), SGS or third-party inspection report, internal QC inspection report, Form E for ASEAN preferential tariff destinations, and material safety data sheet. All documentation is reviewed internally before release — incomplete or incorrect documentation that could cause customs delays is identified and corrected before the shipment departs.

Drawing-to-production compliance is verified at three stages. First, at sample confirmation: the physical sample is measured against the drawing specification across all critical parameters — wire diameter, aperture/pitch, panel dimensions, edge treatment, and surface finish. Any deviation is documented and resolved before the sample is approved. Second, at first-piece production inspection: the first unit from the batch is re-measured against the approved sample. Third, at pre-dispatch full inspection: a defined sample from the batch is re-measured, and the pre-shipment video provides a visual record for client review. The approved drawing, approved sample, and inspection records are kept on file for every order.

If a delivered product does not match the confirmed specification, JBL Metal investigates against the production inspection records, approved sample photographs, and pre-shipment video — which together document the condition of the goods before dispatch. If the non-conformance is attributable to JBL Metal's production, remediation is arranged — which may include replacement production, dimensional adjustment, or agreed compensation depending on the nature and extent of the deviation. All non-conformance cases are documented and used to improve our production process. Our pre-shipment video confirmation process is specifically designed to prevent this situation by giving clients visibility of the goods before dispatch — ensuring any concern is raised and resolved at the factory, not at the project site.
