Composite Decking Manufacturer & Supplier for Trade Buyers
BOHAI is a composite decking manufacturer in Sihui, Zhaoqing, Guangdong. We make capped, classic, hollow and solid composite deck boards for importers, distributors, builders’ merchants, contractors and project buyers.
Buyers comparing composite decking manufacturers and composite decking suppliers need more than a catalogue. This commercial specification hub shows the product range, the information needed for a comparable quotation, how samples and OEM decisions work, and which evidence belongs to which profile. For the separate question of how to verify a factory rather than a trading company, use our six-check factory guide.
The minimum order is 70 m². Standard catalogue production is planned around a 20-day production period before shipping, subject to the confirmed profile, colour, quantity and production slot. Samples are free; the buyer pays the courier and that cost is credited against the first order.

Manufacturer, Supplier or Deck Company?
These labels describe different roles. Compare the role before comparing the price.
A manufacturer controls production
A real composite deck manufacturer controls the extrusion line, tooling, raw-material recipe, profile dimensions, surface and batch record. That matters when a buyer needs a repeatable section, a changed die, a named production slot or evidence tied to the goods being ordered.
A supplier may hold stock and local service
Composite decking suppliers can be manufacturers, importers, national distributors or regional merchants. A composite deck supplier may add stock, small quantities, quick delivery and installation support. Different composite deck suppliers therefore solve different parts of the buying process. A factory-direct supplier adds product and production control but the importer must still plan customs, local stock and after-sales responsibility.
A deck company may design and install
Searches for composite deck companies often include installers as well as material sellers. BOHAI supplies materials to trade and project buyers. Local structural design, permits, foundations, labour and code approval remain with the project team.
Choose the Right Supply Model
The best route depends on what the buyer needs to control.
| Supply model | Best when | What to verify | Typical limitation |
|---|---|---|---|
| Manufacturer direct | Importer, distributor, OEM brand or project volume | Factory identity, profile, batch, documents, Incoterm, QC and repeat-order plan | Buyer manages import route, local stock and local service |
| Importer / national distributor | Local stock, recognised market documents and shorter replenishment | Exact brand/profile, stock depth, warranty handler and replacement route | Less control over tooling and production schedule |
| Regional merchant | Small quantities, collection and local product comparison | Batch continuity, accessory compatibility and delivery promise | Narrower range and a retail/merchant margin |
| Installer-led deck company | One complete local project | Design responsibility, labour scope, foundation, permits and product identity | May not control manufacturing or long-term stock |
| Marketplace listing | Early price and supplier discovery | Legal entity, factory proof, exact specification and independently checked documents | Listing labels do not prove who made the board |

What BOHAI Controls as the Manufacturer
Profile tooling and section drawings
BOHAI owns its moulds and cuts dies in-house. A profile change is therefore a defined tooling question with cost, tolerance and lead time—not a promise relayed to an unknown plant. For verification steps, use the WPC factory checklist.
Surface, colour and production batch
A quotation should name the board range, profile, surface texture, colour and length. Visible areas and practical spare stock should be ordered in one production batch because pigment and surface appearance can vary between runs.
Accessories and the complete system
Board-only prices are not comparable if clips, start clips, joists, trims, fasteners and support components are omitted. The supply schedule should show which accessories are included, which are optional and which remain a local engineering choice.
Factory Capability for a Decking Programme
Commercial controls that matter after the sample is approved
65 extrusion lines
Capacity is planned against a confirmed profile, colour, quantity and production slot.
In-house dies
Dimensioned sections and tooling conversations stay with the plant.
Batch-linked checks
Dimension, surface, colour and packing records should travel with the order.
OEM and private label
Packaging, labels and market documents are agreed before production.
MOQ 70 m²
A first order can test one coherent product route without filling a container.
Export from Guangdong
Nansha and Yantian are the starting ports; the final route ends at the receiving point.
From Enquiry to Repeat Order
The sequence prevents a colour sample from becoming a vague purchase order.
Define the buyer and market
State the country, sales channel, application, receiving point and responsible importer. A distributor launch and one project need different ranges and documents.
Choose a product route
Select the composite decking material route: capped or classic, hollow or solid, then profile, surface, colour and stock length. Use the types of composite decking guide when the route is not yet clear.
Request a sawn sample
Approve the face, wet and dry colour, texture, cut section, cap coverage and clip groove. Record the exact model and colour rather than approving a generic swatch.
Lock the specification
Put the profile code, colour, length, quantity, accessory schedule, packaging, labels, documents and applicable evidence into one written specification.
Compare one commercial boundary
Compare quotations on the same Incoterm, destination, currency, validity, accessory scope and quantity. A low board-only FOB number is not a landed system price.
Approve the production evidence
Confirm the reference sample, tolerances, inspection points, batch identification and pre-shipment record before the run.
Receive and preserve records
Keep the invoice, packing list, arrival record, batch report, retained spare board and installation documents together.
Plan the repeat order
Reorder against the original model, colour, batch history and current sample. Do not assume a name alone guarantees a perfect colour match across production runs.

Composite Decking RFQ Checklist
| Field | Why it changes the offer | Example of a useful answer |
|---|---|---|
| Buyer / channel | Sets range depth, packaging, samples and service model | Regional builders’ merchant launching two colours |
| Application | Changes surface, section, support and evidence questions | Hotel terrace, residential garden or public walkway |
| Profile and range | Defines construction, metre weight, cap and warranty schedule | Capped hollow 23 × 138 mm |
| Colour and surface | Controls production and visual approval | Teak, named grain, approved physical sample |
| Length and quantity | Changes waste, packing, freight and production plan | 4.0 m, 600 m² plus agreed spares |
| Accessories | Makes the quoted system installable | Clips, start clips, joists, trims and specified fasteners |
| Destination and Incoterm | Defines the commercial boundary | CIF Rotterdam or FOB Nansha |
| Required documents | Documents have profile and method scope | Current CE/CPR document and named test report |
| Target date | Connects production slot and sailing plan | Required at warehouse by a specific date |
| Packaging / OEM | May need artwork, language, barcodes and setup | Private-label carton and pallet marks |
OEM, Private Label and Distributor Range Design
Start with a narrow coherent range
A first distributor range works better when one or two profiles, a controlled colour set, matching accessories, samples and installation guidance fit one market position. A large catalogue without stock depth makes replacement and installer training harder.
Separate the product from the brand layer
The purchase specification owns the profile, material route, colour, tolerances and evidence. The brand layer owns product names, label language, carton artwork, barcodes, brochures and warranty presentation. Approve both before production.
Keep document scope visible
Private labelling does not broaden a test report. The local brand should retain the original profile identity and the scope of certificates, declarations and test evidence so a sales claim can be traced back to the supplied board.
Evidence BOHAI Can Identify by Number and Scope
Ask for the current document and confirm that it names the profile or system in the quotation.
| Subject | Reference | Scope boundary |
|---|---|---|
| Quality management | ISO 9001:2015 — IAS25924Q1473R0M, valid to 29 Apr 2027 | Management system; not a performance rating for every board |
| Environmental management | ISO 14001:2015 — IAS25924E0394R0M, valid to 29 Apr 2027 | Management system; not recycled-content certification |
| CE / CPR | M.2024.206.C97619, UDEM, valid to 11 Mar 2029 | Named product/profile scope must be checked before quoting it |
| Slip, shod and oil-wet | Intertek 230625005SHF-001; AS 4586-2013 Appendix D; R10 | Profile ZSGJ138H23A only; not a barefoot pool result |
| Surface burning, US method | SGS GZIN2404000442CM01-1_EN; ASTM E84-23c; FSI 10 / SDI 30 | Named 138 × 23 mm specimen and test method; not an EU reaction-to-fire classification |
| Warranty | Manufacturer limited warranty | Capped and classic ranges use different stepped schedules; read the schedule, exclusions and start date |
Pricing: Compare Specification Before Square Metres
A useful price is tied to a board
The offer should identify profile, range, colour, length, quantity, metre weight, accessories, packing, Incoterm, destination, currency and validity. Without those fields, two prices may describe different boards and different commercial boundaries.
Factory direct does not remove destination costs
Ocean freight, customs, import VAT or tax, terminal charges, inland transport, unloading, storage and local compliance remain part of the buyer’s landed plan. The responsible importer and adviser confirm current tariff and tax treatment.
Use the calculators for the right job
Use the deck material calculator for board count, joists, waste and stock lengths. Installed cost requires local labour, foundations, structure, freight and tax; it should not be invented from a universal per-square-metre website range.
Quality Control and Batch Traceability
Approve one reference
A physical approved sample and a dimensioned profile drawing give production and receiving teams the same reference. Screenshots and colour names alone are not enough.
Check what can actually be measured
The inspection plan can record dimensions, metre weight, surface, colour against the approved reference, fit with clips, quantity, packing and visible damage. Project performance still depends on correct design, installation and exposure.
Keep the batch connected to the shipment
Batch identification, pre-shipment records, packing list and retained samples make a future question reproducible. A broad catalogue warranty without order and batch evidence is harder to administer.

Composite Decking Manufacturer and Supplier FAQ
Company and supply model
Is BOHAI a composite decking manufacturer or a trading company?
BOHAI is the manufacturing and export brand of Guangdong Bangying New Material Co., Ltd. The plant is in Sihui, Zhaoqing, Guangdong, with its own extrusion lines and profile tooling.
What is the difference between composite decking manufacturers and suppliers?
A manufacturer controls production, tooling, specification and batch records. A supplier may be a manufacturer, importer, distributor or merchant that adds stock, logistics and local service. Confirm which role each company performs.
Does BOHAI install composite decks?
No. BOHAI supplies materials to trade and project buyers. Local designers, engineers and installers remain responsible for foundations, structure, permits, labour and code compliance.
What is the minimum order?
The minimum order is 70 m². It is intended to let a buyer test a coherent profile, colour and accessory route without making a full-container first commitment.
Can distributors request private-label composite decking?
Yes. Packaging, labels, market language, branding and document presentation can be discussed. The underlying profile, evidence scope and production specification remain traceable.
Products, documents and orders
Which composite deck boards can BOHAI supply?
The range includes capped co-extrusion, classic uncapped and 3D embossed boards, with hollow and solid sections. Confirm the current model, surface, colour, length and accessory system in the quotation.
How should composite deck manufacturers and suppliers be compared?
Compare the same profile, metre weight, colour, length, quantity, accessories, packing, evidence, Incoterm, destination, currency and validity. A board-only price and a landed system price are not comparable.
Can I receive samples before ordering?
Yes. Samples are free; the buyer pays the courier and the charge is credited against the first order. Ask for a sawn section and record the exact profile, surface and colour.
How long does production take?
Standard catalogue planning uses a 20-day production period before shipping, subject to the confirmed profile, colour, quantity and available production slot. Freight time is separate and route-specific.
What should buyers ask composite deck material manufacturers?
Ask for the exact material route, profile drawing, metre weight, surface, colour, accessory system, tolerances, batch record, warranty schedule and profile-specific evidence. Do not accept a category claim in place of the quoted board specification.
