Linqu, Shandong, China — one of the world's largest building-aluminium clusters OEM & ODM · Private label contact@unionalum.com 中文
Aluminium product design · Manufacturing · Supply chain

Making aluminium products easier for global brands to develop and manufacture.

Our home, Linqu (Shandong, China), is one of the world's most concentrated building-aluminium clusters — extrusion presses, tooling shops, powder & PVDF coating, glass and hardware are all within one hour of our desks. For you, that means faster sampling, tighter costs, and one purchase order for the whole job: engineering to export.

What we manufacture

The six product systems — plus your own design.

Six established ranges in production. Each ships as a finished product, a knock-down kit, or components for a design you own.

Innovation & co-development

Not sure how to develop an aluminium product? Bring us the idea — we'll build it into a product with you.

We welcome innovative partners worldwide. Share a concept, a sketch or a market gap; our engineering team develops it with you from the first drawing to a loaded container. The project below started exactly this way.

Solar Smart Charging Station

Outdoor power, seating, lighting and digital information in one integrated public unit — engineered for parks, campuses and smart-city projects.

  • High-efficiency solar canopy with battery storage — fully off-grid
  • USB / USB-C and wireless charging on the table surface
  • LED lighting, digital information display and security camera
  • Accessible charging port — inclusive by design
  • Aluminium structure engineered for year-round outdoor use
Why clients work with us

You get one partner, not another supplier to manage.

Extruding aluminium is easy to find. Coordinating multiple processes into one product is not.

"My order needs six factories and I only have time for one."

All processes run as one order, one contact. You manage one relationship, not a vendor list.

"I need a sample before I commit to tooling."

We engineer and prototype first. You approve a physical sample before volume.

"The product has to carry my brand, not a factory's."

Private-label production, your packaging, your artwork. Your drawings stay confidential.

"My margin lives or dies on landed cost."

Shared profiles, standardised parts and container-fill design cut cost — without changing the design.

"I can't afford a supplier that disappears mid-project."

Defined stages, named deliverables, one account team that stays on your product.

"I don't want to explain my product to five people."

One technical contact, one shipment plan. Fewer handoffs, fewer delays.

How a project runs

From a drawing, a sample or an idea — to a loaded container.

01

Brief & feasibility

Send a drawing, a sample or the market requirement. We come back with the route and the cost drivers.

You receive: feasibility note + proposed manufacturing route
02

Design & engineering

Structure, material, extrusion section design and cost engineering — reviewed before anything is cut.

You receive: structure drawings, section design, material and finish options
03

Prototype & validation

A physical sample to test look, function and fixings with your own team or your customer.

You receive: prototype sample + validation notes
04

Tooling, sampling & approval

Dies and fixtures are made, first-article inspection runs, colour and finish are approved.

You receive: first-article approval record + colour standard
05

Production & quality control

Batch production with inspection at the stages that matter: material, machining, finish, assembly.

You receive: process records + inspection results
06

Assembly, packing & export

Knock-down design where it saves freight, protective packing, container loading and export documents.

You receive: packing list, loading record, export documents
How we can work together

Five ways to place your product with us.

01

OEM manufacturing

You supply the drawing, sample and quality standard. We manufacture to it.

  • Built to your drawing
  • First-article approval
  • Repeat-order consistency
02

ODM product development

You bring the market need. We develop structure, materials and samples with you.

  • Concept to validated sample
  • Material and process choice
  • Cost engineered in design
03

Standard product supply

Modular, repeatable product lines for your brand or retail channel.

  • Shared profiles per family
  • Retail or trade packaging
  • Forecast-based scheduling
04

Custom fabrication

Project work where size, structure or finish is not standard.

  • Non-standard spans
  • Project-quantity batches
  • Site-drawing coordination
05

Supply chain integration

Profiles, hardware, finishing, assembly and packing — one order instead of eight.

  • Consolidated suppliers
  • Inspection at each handoff
  • One container, one document set
06

Not sure which one fits?

Describe the product and market. We will tell you which route we would take.

The cluster advantage

Most suppliers will only quote you for extrusion. We turn the whole cluster into one order.

Presses, coating lines, CNC shops, hardware and plastic suppliers — all within a short drive. Capacity was never the problem. Coordinating it is what we do.

  • 1
    One contract, many processes Profile, machining, finishing, hardware, assembly and packing under one order.
  • 2
    Consolidated shipping Components arrive together and load into one container.
  • 3
    Fewer places for defects to hide Incoming inspection and defined handoffs between processes.
  • 4
    Cluster cost, without the broker layer Direct access to regional capacity, organised around your product.

Manufacturing & supply chain capability

Every stage of the product, under one order.

Own process control where it decides quality; cluster capacity where it decides cost.

Extrusion & die development

Sections designed around your product, with dedicated die development.

Surface treatment

Powder coating and anodising, with colour, texture and wood-grain effects.

Precision machining

CNC machining, cutting and drilling to your dimensional tolerances.

Welding & assembly

Welding, structural connections, hardware fitting and modular assembly.

Multi-material sourcing

Hardware, plastic parts and fasteners consolidated into one package.

Packing & export delivery

Knock-down design, set packing, container loading and export documents.

Who we are

A product partner built on Linqu's aluminium industry — not a catalogue seller.

We supply profiles and machined parts, but that is not the product. The product is your finished item, on your brand, in one container with the paperwork your customer expects.
