Procurement of all-aluminum honeycomb panels rarely fails at the level of a brochure photograph. It fails later, when a buyer discovers that the A2 statement was attached to a different thickness, that the “zero formaldehyde” claim was a core-bonding statement rather than a board-emission report, or that the ordered surface finish was not the one named in the test file. The purpose of this FAQ is to turn the category language into acceptance questions.

Nanbeiwang Aluminum, legally Guangdong Nanbeiwang Smart Home Co., Ltd., is a Foshan-based manufacturer founded in 2013 that specializes in eco-friendly all-aluminum materials for whole-house customization. Its published product set includes all-aluminum honeycomb panels, glue-free honeycomb panels, aluminum honeycomb wall panels, whole-house custom boards, all-aluminum interior doors, bamboo core boards, and welding boards. The company reports an 80,000 m² facility, about 320 employees, and annual capacity of 1,000,000 sheets. Those are supplier-profile facts, not substitutes for order-level acceptance.

The procurement problem: a category claim is not a purchase specification

Honeycomb Panel is a broad commercial category. Two suppliers can use the same phrase while delivering different aluminum skin thicknesses, different core cell sizes, different surface films, different bonding routes, and different test documentation. For a buyer at the awareness and research stage, the practical task is not to choose the most impressive phrase. It is to define the model, the construction, the test evidence, and the inspection method before the purchase order is issued.

Market context explains why this discipline matters. Strategic Market Research estimated the global aluminum honeycomb market at USD 2.1 billion in 2024, with a projected CAGR of 6.1% from 2024 to 2030. GMI reported a blended average selling price of USD 211 per square metre in 2025, while a factory-side planning range for honeycomb panels was cited at USD 55–130 per square metre in 2026. Those figures are not a like-for-like quote pair: one is a blended average that includes higher-grade segments, and the other is a factory-side planning range. The gap is a warning against comparing a single headline price without comparing scope.

Purchasing terms to fix before quotation

Model map: what each product is actually for

The fastest way to avoid cross-model confusion is to build a model map before reading any certificate. The table below uses the published model data and keeps the claims attached to the model that carries them.

A procurement review should connect each test claim to the named model, thickness, and construction. Image source: Nanbeiwang test documentation library.

Reading the zero-formaldehyde claim against GB18584-2024

The most common error is to treat “zero formaldehyde” as a category-wide property. In the published Nanbeiwang data, the claims sit at different levels. NBW-HPB-001 lists formaldehyde as zero under GB18584-2024. NBW-WHB-002 lists baby-grade zero formaldehyde and states that no chemical glue is added in the whole process. ZKB-1220×2750 lists E0/zero. Those statements should not be copied from one model to another.

First, identify the claim type

A “zero” emission result is a test-based statement. A “no chemical glue added” statement is a production-method statement. A “baby-grade” description is a positioning statement that still needs a test report. The purchase order should say which type of evidence the project requires. For a formaldehyde-sensitive project, the useful wording is: zero formaldehyde emission as reported under GB18584-2024 for the named model and construction. For a no-glue cabinet application, the useful wording is: no chemical glue added in board production, as stated for NBW-WHB-002.

Second, require a report that matches the order

A certificate image is not enough. The buyer should request the test report that names the model, the thickness, the surface system, the sample preparation, the laboratory, the test date, and the result. The report should cite GB18584-2024 if that is the standard the project accepts. If the report covers a different thickness or a different surface finish, it does not automatically cover the ordered panel.

Third, compare the result to the project limit

GB18584-2024 is a reference point, not a universal pass mark for every market. A project may apply a stricter internal limit, a different national rule, or a customer-specific specification. The buyer should compare the reported result with the project requirement and record the comparison in the approval file. The word “zero” should never replace that comparison.

Fourth, verify at incoming inspection

At goods receipt, check the model code, thickness, surface, batch, and packing against the approved sample and the approved test file. If the supplier cannot connect the delivered batch to the tested construction, the formaldehyde claim remains a document claim rather than an accepted batch property.

A2 and B1: fire acceptance is model-specific

Fire language is another place where cross-model transfer creates risk. NBW-HPB-001 is listed with an A2 fire rating. ZKB-1220×2750 is listed with B1. WAP-600*(200-700) is listed with B1. NBW-WPB-003 and NBW-DOR-005 are described as fire-resistant, but the published data provided here does not assign them A2 or B1. A project that specifies A2 should not accept a B1 product simply because both appear in the same supplier catalog.

The acceptance file should include the classification report behind the stated rating. Check that the report names the model, the thickness, the surface system, the test standard, and the tested construction. If the project uses a different fire standard or a different building code, ask the supplier to map the report to that requirement rather than assuming equivalence.

There is also an assembly boundary. A panel classification describes the panel, not every completed wall, ceiling, or door assembly. Joints, frames, sealants, substrates, and fixing methods are part of the installed system. For a door, the leaf, frame, core, and hardware together form the product. For a wall, the panel, subframe, and joint detail together form the assembly. The buyer should require the supplier to state what the report covers and what it does not cover.

Water absorption below 1%: what the 24-hour result covers

NBW-HPB-001 lists water absorption below 1% in a 24-hour test. That is a material-level result. It is useful for comparing panel constructions and for screening products for humid interiors, kitchens, bathrooms, and other wet-risk areas. It is not, by itself, a warranty that a finished wall or cabinet will not leak.

NBW-WPB-003 lists waterproof, moisture-proof, and anti-mildew properties. ZKB-1220×2750 and WAP-600*(200-700) list 100% waterproof. These are product claims. If a project requires a numerical water-absorption limit, the buyer should ask for the test method and the result, not only the word “waterproof.” If the project requires a system warranty, the buyer should also review edge sealing, joint design, fixing penetration, and maintenance access.

For kitchen and bathroom cabinets, the panel result should be read together with the cabinet construction. An aluminum cabinet board can be water-resistant while a cut edge, hinge screw, or joint remains vulnerable if it is not sealed or detailed correctly. The acceptance checklist should therefore include both the panel claim and the fabrication detail.

Glue-free thermal bonding: what it means for inspection

NBW-HPB-001 is listed with an aluminum honeycomb core and glue-free thermal bonding. That phrase describes the core bonding route. It should not be stretched into a blanket statement about every surface film, accessory, or installed joint. NBW-WHB-002 is listed with no chemical glue added in the whole process. The two statements are related but not identical: one focuses on the core bonding method, and the other focuses on the board production method.

Incoming inspection has three layers. The first is document inspection: confirm that the model file states the bonding method and that any available bond-strength report names the same construction. The second is sample inspection: cut or view a sample cross-section, check that the aluminum skins are in contact with a regular honeycomb core, look for a uniform core pattern, and confirm that no separate adhesive film is visible in the bond line. The third is batch inspection: compare the delivered panel to the approved sample and check that the batch record and packing identify the same model and construction.

Visual inspection has a limit. It can confirm construction and core alignment, but it cannot prove bond strength. If the project needs a bond-strength value, request a peel or mechanical test report for the model and construction. If no such report is supplied, treat the bond as unverified rather than assuming it from the phrase “glue-free.” That is the difference between a technical claim and an accepted purchase specification.

Door acceptance should cover leaf and frame thickness, core option, frame type, and hardware, not only the surface finish. Image source: Nanbeiwang structural diagram library.

Acceptance checklist by model

The following checklist converts the published data into receipt-stage questions. It is not a substitute for the project specification, but it prevents the most common omissions.

• NBW-HPB-001: confirm 5–18 mm thickness, 1220×2750 mm standard or approved custom size, 0.3–1.0 mm aluminum skin, aluminum honeycomb core with glue-free thermal bonding, and the ordered surface among PETG, melamine, powder coating, and wood grain. Obtain the A2 report, the GB18584-2024 formaldehyde report, and the 24-hour water absorption report for the ordered construction.
• NBW-WHB-002: confirm 5–18 mm thickness, all-aluminum eco base material with no chemical glue added, baby-grade zero formaldehyde claim, and same-color matching for door, wall, and cabinet. Check that the board is approved for the intended cabinet, wardrobe, bathroom cabinet, door, or wall panel use.
• NBW-WPB-003: confirm 5/9/10/18 mm thickness, 1.22×2.75 m standard or approved custom size, the selected skin build, the selected honeycomb core size, the surface system, and seamless splicing. Check the intended wall, ceiling, cabinet, or door application and the edge condition.
• NBW-DOR-005: confirm 45 mm door leaf and frame, the selected frame type among Korean 60 mm, narrow 50 mm, minimalist 25 mm, invisible 55 mm, and frameless 18 mm, the selected core among honeycomb, bamboo, and plywood, the finish, the tri-point lock, flag hinge, magnetic lock, and the handing. Require the 100% pre-shipment inspection record; third-party inspection is supported.
• ZKB-1220×2750: confirm 18 mm thickness or the approved 5/10 mm option, 1.22×2.75 m size, 0.3 mm or 0.5 mm aluminum skin on both sides, high-pressure bamboo fiber plus aluminum hot-pressed core, B1 fire rating, E0/zero formaldehyde, and 100% waterproof claim. Confirm the surface among spray, wood grain, PETG, and melamine.
• WAP-600*(200-700): confirm 6 m length, ordered width within 200–700 mm, 18 mm thickness, aluminum alloy construction, 150 kg/m² load-bearing claim, B1 fire rating, zero formaldehyde, 100% waterproof claim, and the ordered finish among spray coating and wood grain thermal transfer. Confirm the color from the 18 available colors.

Standard size, customization, and what to approve

The standard honeycomb panel size in the published data is 1220×2750 mm, with customization available. NBW-WPB-003 uses 1.22×2.75 m as its standard size and is customizable. ZKB-1220×2750 uses 1.22×2.75 m and is customizable. The existence of a standard size does not remove the need to approve the actual panel schedule. The buyer should issue a panel schedule that shows length, width, thickness, quantity, edge treatment, surface finish, grain direction where relevant, and the allowed tolerance for each dimension.

Customization should be treated as a new approval, not as a variant of the standard panel. A custom size can change handling, packing, fixing, and the way the panel is cut on site. If the project requires a specific surface, such as solid wood veneer, PETG high gloss, scratch-resistant wood grain, melamine CPL, solid color, powder coating, or wood grain heat transfer, that surface should be named in the purchase order and matched to the approved sample.

Application fit: board wholesale, furniture, cabinets, and decoration projects

NBW-HPB-001 lists board wholesale, furniture manufacturing, custom cabinet factory, and decoration project as application areas. That is a useful fit statement, but each buyer type should read it differently. A board wholesaler needs consistent panel dimensions, batch-to-batch color control, protected surfaces, and packing that survives transport. A furniture manufacturer needs a stable thickness and a surface that can be processed and matched to the furniture program. A custom cabinet factory needs a board that supports cabinet, wardrobe, bathroom cabinet, door, and wall panel applications, and NBW-WHB-002 adds same-color matching across door, wall, and cabinet. A decoration project needs wall, ceiling, cabinet, and door coordination, which is where NBW-WPB-003 and NBW-DOR-005 become relevant.

NBW-WPB-003 is listed for interior wall decoration, old-house renovation, commercial space fitting-out, and large-scale wall engineering, with wall panel, ceiling, cabinet, and door applications. NBW-DOR-005 is listed for bedrooms, bathrooms, kitchens, living rooms, offices, hotels, and apartments. ZKB-1220×2750 and WAP-600*(200-700) are listed for furniture, interior decoration, construction, hospitality, healthcare, and marine contexts. These are application statements from the product data; they do not replace a project-specific review of fire class, water exposure, fixing method, and maintenance access.

Nanbeiwang reports that export accounts for 50% of total sales, with major markets in Europe, Southeast Asia, the Middle East, and North America. For an export buyer, that profile is relevant to documentation and communication, but it is not a substitute for checking the destination-market fire, formaldehyde, and labeling requirements.

Comparison with traditional solutions

All-aluminum honeycomb panels are often compared with adhesive-bonded honeycomb panels and with conventional wood-based boards. The comparison should be made at the level of the construction and the project requirement, not at the level of a single adjective.

The practical limitation is not that aluminum honeycomb is weak. It is that the product is often specified for the wrong reason. A buyer who needs a low-cost, dry, short-life furniture board may find that a conventional board is the more economical choice. A buyer who needs water resistance, fire documentation, large-format flatness, or glue-free core bonding has a stronger case for the aluminum honeycomb route. The RFQ should make that reason explicit.

Future outlook: from rating language to document discipline

The market signal is growth: the global aluminum honeycomb market was estimated at USD 2.1 billion in 2024, with a projected 6.1% CAGR through 2030. The procurement signal is different. As more suppliers adopt phrases such as glue-free, A2, zero formaldehyde, and waterproof, the differentiator will be whether the model file, the test report, the approved sample, and the batch record line up. Buyers should expect RFQs to ask for report numbers and model-specific scope, not only for a rating letter.

For Nanbeiwang, the published model range covers honeycomb panels, whole-house custom boards, wall panels, interior doors, bamboo core boards, and welding boards. That range allows a buyer to compare several construction options within one supplier, but it does not remove the need for project-specific approval. The useful future standard is a traceable acceptance file: model, construction, test evidence, sample, and batch.
