Manufacturing & supply chain

Our own process control where it decides quality, and qualified specialist capacity from the Linqu cluster where it decides cost and scale — organised as one order, not eight.

Capability

Every process stage, and where each one sits with us.

This is the part overseas buyers usually have to assemble themselves, across separate suppliers, separate quotes and separate shipping windows.

01

Aluminium extrusion & die development

Sections designed around your product's structure, load path and application — not picked from whatever dies happen to exist. We develop dedicated dies where the product needs them, and organise production across a range of profile sizes so wall thickness, strength and material use are balanced against cost.

Typical outputs: section drawings, die specification, extrusion samples
02

Surface treatment

Powder coating and anodising, with colour, texture and decorative effects coordinated to your range — including wood-grain finishes. Finish quality is agreed against a physical standard before production, and coating thickness and adhesion are checked as part of inspection.

Typical outputs: colour standard, finish sample, coating thickness records
03

Precision machining

CNC machining, cutting and drilling to the dimensional and assembly tolerances your product actually needs. Where a component is invisible once installed, we machine to the function rather than to an unnecessary tolerance — that decision shows up in your landed cost.

Typical outputs: first-article inspection, dimensional records
04

Welding & assembly

Aluminium welding, structural connections, hardware fitting and modular assembly — up to the complete finished product. Where a knock-down structure saves more freight than it costs in assembly, we design for that instead.

Typical outputs: welded frames, sub-assemblies, tested finished units
05

Multi-material sourcing

Metal hardware, plastic parts, fasteners, seals and other components consolidated into the same product package. You receive one delivery against one purchase order, rather than five partial shipments you have to reconcile yourself.

Typical outputs: consolidated bill of materials, single packing list
06

Packing & export delivery

Knock-down structure design, set packing, container loading plans and export documentation — built for transport, storage and channel distribution, so goods arrive ready for your warehouse or your dealer rather than as a repair job.

Typical outputs: packing design, loading plan, loading photographs, document set
07

Regional manufacturing integration

The Linqu aluminium industry gives us access to press capacity, coating lines, CNC shops and component suppliers within a short distance. We coordinate those processes and their inspection points under one programme, so the customer sees one supplier and one quality standard.

Typical outputs: supplier qualification records, incoming inspection records
Why this cluster matters to you

The cluster is not a talking point. It is your supply chain.

Linqu County in Shandong is one of the densest aluminium extrusion and processing regions in China. Extrusion presses, anodising and powder coating lines, CNC machining shops and hardware suppliers sit within a short drive of each other. Every one of them is capable. Almost none of them will take responsibility for assembling the whole product for you.

That gap is exactly where we sit. We are the party that holds the product together — the technical drawing, the finish standard, the inspection points, the packing design and the container plan — and answers for all of it.

  • 1
    You audit one supplier, not a network Qualification, technical review and quality evidence come from one place, on one document set.
  • 2
    One container instead of eight part-shipments Components are staged, checked and loaded together against a single loading plan.
  • 3
    Defects are caught at the stage that caused them Incoming inspection at each handoff, rather than discovering the problem after assembly.
  • 4
    Capacity is matched to your order, not to a broker's Processes are selected for your product and your volumes, and re-selected when your volumes change.

Quality & compliance

What we can prove — and whose name is on the certificate.

Sourcing from China responsibly means knowing which factory holds which certificate, for which process. We would rather show you the right documents than make a claim that does not survive your due diligence.

Our position on certification

Our own process control covers incoming material, machining, surface finish, assembly and final packing, and we only place work with qualified partner factories. We do not present a single group-wide certificate, because the manufacturing is distributed.

Where your market, your customer or your tender requires certification, the certificate belongs to a specific factory and a specific process. We identify the correct factory for your product, provide the current certificate set covering that product and process, and arrange third-party inspection if you need independent confirmation.

If your tender needs a named certificate before we start, tell us at the feasibility stage and we will confirm what is available for your specific product rather than after you have quoted it.

Documents we can supply on request

  • Supplier qualification and factory audit records
  • Material certificates — alloy and temper
  • Coating thickness and adhesion test results
  • First-article inspection and sample approval records
  • Dimensional inspection reports for machined components
  • Third-party inspection coordination — SGS, BV, TÜV or your nominated agency
  • Container loading photographs, packing list and export documents
  • Sample and prototype approval records
Packing & loading

Freight is part of the design, not an afterthought.

Aluminium is bulky and light, which makes the way a product packs a commercial decision, not a warehouse detail. We design knock-down structures and nesting arrangements so more product fits in the container, and we plan the loading sequence before production rather than after.

  • ✓
    Knock-down design where it pays Structures designed to be flat-packed and assembled in your market when the saving in freight outweighs the cost of local assembly.
  • ✓
    Set packing, not bulk packing Components for one unit packed together with fittings and instructions, so nothing is sorted on arrival.
  • ✓
    Loading plan and photographs You see how the container was loaded, against the packing list, before the vessel sails.
  • ✓
    Export document set Commercial invoice, packing list, bill of lading and certificates coordinated with your forwarder.
