GNEE Aluminum has completed the packing and dispatch of a multi-thickness order of 5083 H116 aluminum plate for a marine-fabrication buyer. The order combined four thicknesses - 4 mm, 5 mm, 6 mm and 10 mm - all cut to the full 2000 × 6000 mm sheet size, and the whole lot was released under Bureau Veritas (BV) classification survey together with an EN 10204 3.1 mill test certificate. The buyer's decision to consolidate four thicknesses into one 5083 H116 order reflects a common purchasing pattern in ship repair and hull outfitting work, where plating for hull shells, decks, bulkheads and superstructures is sourced from a single certified batch to keep weldability and traceability consistent.
For marine and transport fabrication, procurement teams do not only compare price per ton - they compare weight per piece, because freight quotation, crane capacity on site, cutting plans and hull weight budgets are all planned around the weight of individual sheets. A 10 mm sheet of 5083 H116 plate at 2000 × 6000 mm weighs 327.60 kg, more than twice the 131.04 kg of the 4 mm sheet in the same order, and this difference directly affects how the plates are palletized, lifted and routed through the customer's workshop. For that reason, the unit weight of every size in this order was stated explicitly in the order confirmation, and the same figures are reproduced below so that other buyers can use them as reference values when budgeting their own 5083 H116 requirements.

Quality Control for the 5083 H116 aluminum plate order
Ultrasonic test (UT) per ASTM B594 - detects internal laminations or inclusions in the plate that are invisible on the surface and could fail under wave-induced loading in hull service.
Tensile test per heat / lot (recorded on the MTC) - confirms that yield strength, tensile strength and elongation meet the 5083 H116 requirements of ASTM B209 and the BV rule requirements before the lot is released.
Thickness and flatness measurement - verifies each sheet against the dimensional tolerance class ordered, so plating fits fabrication jigs and welds without excessive distortion.
Visual and edge inspection - checks surface condition, edge quality and handling damage, since edge cracks propagate in welded marine structures.
Bureau Veritas (BV) surveyor witness - the certification body audits the material, marks and certificates so the plates are accepted directly by the classification society at the customer's yard.
Heat number traceability and stencil marking - every sheet carries grade, temper, heat number and BV marks for full traceability from MTC to installed plate.
Export Packaging for the 5083 H116 aluminum plate shipment
Plates of this size and weight are shipped on strong export-standard timber pallets or steel stillages, with each bundle capped at a safe lifting weight and separated by protective interleaving to prevent surface scratching. Edges are protected, and desiccant plus waterproof wrapping guard against sea-freight moisture, which matters because white rust on freshly milled marine plate can interfere with later welding and painting. Each bundle is labelled with grade, temper, size, heat number and gross/net weight so the customer's warehouse can reconcile goods against the packing list and MTCs without re-measuring. Standard shipping documents - commercial invoice, packing list, EN 10204 3.1 certificates, BV certificate and certificate of origin - are issued with the shipment.

FAQ
What is the unit weight of a 5083 H116 aluminum plate at 2000 × 6000 mm?
For this shipment the confirmed unit weights were 131.04 kg/pc at 4 mm, 163.80 kg/pc at 5 mm, 196.56 kg/pc at 6 mm and 327.60 kg/pc at 10 mm. Piece weight scales almost linearly with thickness, so these figures work as reference points when you estimate freight and cutting plans for other thicknesses at the same sheet size.
Can GNEE supply 5083 H116 aluminum plate with BV (Bureau Veritas) certification?
Yes. GNEE supplies 5083 H116 marine plate under classification society certification including Bureau Veritas. An EN 10204 3.1 mill test certificate ships with every order as standard, and 3.2 certificates or class surveyor witness inspection can be arranged for project work.
What is the MOQ and lead time for 5083 H116 marine aluminum plate?
MOQ is flexible and small trial orders are welcome. Standard lead time is 15–30 days depending on the thickness mix and certification scope; common marine sizes held in stock can be dispatched sooner.
