Custom Sheet Metal Fabrication Manufacturer in China

  • Custom metal parts and brackets made to your drawings
  • Manufacturing based in Hangzhou, China
  • Laser cutting, bending, stamping and welding
  • Coordinated surface finishing, assembly and packaging

Our sheet metal work combines cutting, forming and joining to produce custom metal components. We also coordinate surface finishing through external processing partners, together with assembly and packaging requirements for the order.

Custom Sheet Metal Parts & Assemblies

We manufacture flat metal parts, formed brackets, custom components and metal housings for drawing-based orders. Cutting, bending, stamping and welding are selected around the part’s geometry and application. Material, thickness, joining and finish requirements work together to define the manufacturing route.

Materials

  • Material grade affects strength, corrosion resistance and forming behavior.
  • The base material and finish should suit the part’s intended environment.

Thickness

  • Thickness influences weight, rigidity and bend behavior.
  • Suitable thickness depends on the material, geometry and application.

Fabrication Processes

  • Laser cutting for sheet profiles and openings
  • Bending for angles, flanges and formed shapes
  • Stamping for formed metal features
  • Welding for joined components

Assembly Coordination

  • Mating parts and fixing positions
  • Component orientation and fit
  • Related hardware requirements
  • Packaging for the finished part or assembly

Surface Finishing

  • Arranged through external processing partners
  • Selected to suit the base material and application
  • Color and appearance requirements included in the order specification

Why Work with JIANSEN

A custom metal part needs more than a matching outline. Formed features, fixing positions, joined components and surface requirements all affect how the part works in its final application. Our work brings these requirements into the same manufacturing discussion.

Drawing-Based Production

We work from part drawings and specifications, with attention to dimensions, hole positions and assembly interfaces.

Connected Fabrication Processes

Laser cutting, bending, stamping and welding support different part features, from flat profiles to formed and joined components.

Custom Parts and Established Hardware

Alongside custom fabrication, our regular hardware ranges cover doors, gates, furniture and structural connections.

Coordinated Surface Finishing

Surface treatment is arranged through external processing partners according to the order’s finish requirements.

Direct Discussion with Our Team

Work with our Hangzhou team to discuss the part, application and order requirements before proceeding.

Drawing-Based Quotation & Project Review

Custom sheet metal pricing depends on more than a part’s outline. Material grade, thickness, bend features, joining requirements, finishing and order quantity all affect the manufacturing route.

We use your drawing and order details as the starting point for a quotation discussion. Critical dimensions and mating features should be considered alongside the visible part geometry.

  • Dimensioned drawings define the part geometry.
  • Material and thickness influence processing choices.
  • Joining and finishing affect the completed component.
  • Quantity and packaging help establish the order scope.

Welding & Assembly for Custom Metal Parts

Welding joins separate metal pieces into a fabricated component, while assembly brings related parts together around their fixing and mating features. Joint positions, visible surfaces and installation requirements help define the finished result.

Welding for Fabricated Components

Our welding work supports custom metal components and bracket assemblies. Joint locations, mating features and visible faces help define the joining requirements. These details belong alongside the dimensions and geometry in the part specification.

Assembly Around the Final Application

Assembly requirements depend on how the parts locate, connect and fit together. Fixing positions, component orientation and access for installation all matter. Related hardware and packaging can be discussed together with the fabricated parts.

Our Metal Manufacturing Services

Laser Cutting

Cut sheet profiles and openings for custom metal parts. Material, thickness and part geometry define the cutting requirements.

Bending

Form angles, flanges and brackets from cut sheet parts. Bend features should be considered together with holes and mating surfaces.

Stamping

Produce formed metal features for hardware and custom components. Part geometry and order quantity help define the production approach.

Welding

Join metal pieces into fabricated components and assemblies, with joint locations and appearance requirements defined for the part.

Assembly Coordination

Bring related components and hardware together around fixing positions, orientation and the intended installation.

Surface Finishing Coordination

Arrange surface finishing through external processing partners, based on the material, appearance and application requirements.

Sheet Metal Fabrication FAQs

What kinds of custom sheet metal parts do you manufacture?
Our work includes flat metal parts, formed brackets, custom components and metal housings. The manufacturing route depends on the part geometry, joining requirements and intended application.
How should I choose the material for my part?
Material selection depends on strength, corrosion exposure, weight, forming requirements and the intended finish. If your design already specifies a material grade, include it in the drawing. Where material options remain open, the application provides a useful starting point for discussion.
What sheet thickness should I specify?
Thickness affects stiffness, weight and forming behavior. A thicker sheet is not automatically the most suitable choice, because bends, flanges and part geometry also influence rigidity. The appropriate thickness and manufacturing route need to be considered for the specific part.
Which files are useful for a quotation?
A dimensioned PDF drawing and available CAD files, such as DXF, DWG or STEP, help explain the part. Include the material, thickness, quantity and finish requirements, and identify any critical dimensions or assembly interfaces.
Is surface finishing carried out in your own factory?
Surface finishing is arranged through external processing partners. The required finish should be discussed together with the base material, appearance and intended use of the part.
How are order quantity and lead time determined?
Quantity and the requested delivery date form part of the quotation discussion. The production arrangement depends on the part, processing route, finishing and order scope. Applicable quantities and delivery terms are confirmed for the individual order.
Can I also enquire about standard hardware products?
Yes. Alongside custom metal parts, we supply fence and gate hardware, barn door hardware, garage door hardware, metal furniture legs, pergola brackets and shelf brackets. A product model or reference image helps identify the hardware you need.
