Finding a reliable sheet metal fabrication company in China takes more than comparing quotes. You need a factory that reads drawings correctly, controls quality, and ships on time. Zhangjiagang Zhongfu Metal Products Co., Ltd. (Zhongfu Metal) is a sheet metal fabrication company in Zhangjiagang, Suzhou, Jiangsu. We make custom cabinets, control boxes, instrument enclosures, welded frames, and stainless steel vessels from your drawings or samples.
This guide explains what we make, how a project moves from RFQ to shipment, and what to check before you choose a sheet metal manufacturer. It is written for importers, OEM buyers, contractors, and purchasing teams.
Custom Sheet Metal Fabrication Factory with Laser Cutting, CNC Bending & Welding
Zhongfu Metal runs complete in-house production lines. A typical sheet metal part moves through these steps in one factory:
• Laser cutting to produce accurate flat blanks
• CNC metal bending to form angles, boxes, and covers
• Metal welding to join parts into rigid assemblies
• Surface treatment and assembly preparation before inspection
Keeping these steps under one roof means fewer hand-offs between suppliers. It also makes delays easier to find and fix. This is the main reason buyers choose a custom sheet metal fabrication factory over several separate workshops.
ISO 9001 Sheet Metal Manufacturer for Global OEM & ODM Orders
We support export-oriented industrial projects with ISO 9001 quality management. We build to your drawings, samples, technical standards, and brand requirements. Our OEM & ODM service covers size, material, logo, appearance, and structural changes.
Good practice: ask any supplier, including us, for a copy of the certificate and the scope it covers. A real sheet metal manufacturer will share it without delay.
One-Stop Sheet Metal Fabrication from Drawing Review to Export Shipment
Managing five suppliers for one product is slow and risky. We combine the full route in one factory: drawing review, sample development, production, inspection, packing, and export shipment.
You can start with CAD, PDF, or 3D files, or with a physical sample. Our engineers review the design and advise on feasibility before we quote. This early review often catches problems that would otherwise appear after production starts.
Factory-Direct Sheet Metal Parts, Cabinets & Enclosures from Jiangsu, China
Our factory is in Zhangjiagang, Suzhou, Jiangsu, one of China’s main manufacturing regions. We sell factory direct, so you deal with the people who make your parts. Our main sheet metal product groups include:
• Industrial sheet metal cabinets and equipment housings
• Control boxes and instrument enclosures
• Welded frames, racks, and turnkey assemblies
• Stainless steel tanks and process vessels
We also machine CNC parts, cast, and forge, so mixed assemblies can stay with one supplier.
Precision Sheet Metal Fabrication for Industrial Equipment Manufacturers
Equipment makers need parts that fit the first time and repeat on every order. That requires clear drawings, consistent bending, and stable welding.
We confirm dimensions, material, and critical tolerances from your drawing before production. Typical precision sheet metal fabrication parts include equipment housings, instrument protective covers, control boxes, and structural frames that need both accuracy and strength.
Our work also supports beverage equipment, small pressure vessel systems, sports equipment, and public safety structures. These projects show how one factory can handle thin sheet, tube, and heavier welded work for different industries.
What Does a Sheet Metal Fabrication Company in China Do?
A sheet metal fabrication company turns flat metal sheets into finished parts. It cuts the sheet, bends it into shape, joins the pieces, and finishes the surface. The result may be a single bracket or a complete cabinet.
Many buyers source from China for three reasons: a complete supply chain, flexible order sizes, and strong export experience. The risk is choosing a supplier that cannot match its promises. The sections below show how to check.
What buyers should expect from a good supplier
• A clear review of your drawing before any price is given
• Honest feedback if a design is hard to bend, weld, or finish
• Written confirmation of material, thickness, finish, and quantity
• Inspection records and photos before shipment
Sheet Metal Fabrication Services: Laser Cutting, Bending, Welding & Finishing
Our sheet metal fabrication services cover the processes below. Each one connects to the next, so the table shows how they fit together.
| Process | What it does | Typical use in sheet metal projects |
| Laser cutting | Cuts flat sheet into exact shapes and openings | Cabinet panels, brackets, enclosure blanks |
| CNC bending | Folds flat parts into angles and boxes | Housings, covers, frames, control boxes |
| Welding | Joins formed parts into rigid assemblies | Cabinets, racks, equipment frames, tanks |
| Metal stamping | Presses repeatable shapes with a die | Higher-volume brackets and small parts |
| Surface treatment | Finishes parts for appearance and protection | Finished cabinets and enclosures |
Ask your supplier which finishes it offers in-house and which it outsources. Confirm your required finish before quotation.
Custom Sheet Metal Cabinets, Control Boxes & Instrument Enclosures
Enclosures are one of our core product lines. They need accurate cutouts, clean bends, and strong welds. They also need to protect what is inside.
Typical products
• Industrial cabinets and equipment housings
• Control boxes and electrical enclosures
• Instrument covers and protective housings
• Tool tables, workshop frames, and support stands
A good enclosure design also considers assembly. Door fit, cable openings, mounting holes, and access for service all affect how easy the final product is to use. We flag these points during drawing review so you can adjust the design before production, not after.
What to send us
Share the drawing, material, wall thickness, finish, and quantity. If the enclosure has a protection requirement, tell us the working environment. This helps us suggest the right material and structure.
Stainless Steel, Carbon Steel & Aluminum Sheet Metal Fabrication
We process stainless steel, carbon steel, aluminum alloy, copper, and iron. We can also advise on the right choice for your use case.
• Stainless steel: resists corrosion. Common in food, beverage, and process equipment.
• Carbon steel: strong and economical. Usually needs a protective finish.
• Aluminum alloy: light and easy to form. Useful where weight matters.
Tell us where the part will be used. Outdoor, humid, and chemical environments change the best material choice.
Material cost also affects your final price. A thicker sheet adds weight and shipping cost, while a thinner sheet may need extra ribs or bends for strength. Our engineers can suggest a balance between cost, strength, and appearance when they review your drawing. If you have not chosen a material yet, send the intended use and we will recommend options.
From RFQ to Shipment: How Our Sheet Metal Fabrication Process Works
Projects run best when the basics are clear early. Our process follows four steps:
• Inquiry intake: we collect category, quantity, finish, destination, and drawing status.
• Route planning: engineering decides which sheet, machining, vessel, or welded route fits.
• Production: forming, CNC machining, welding, finishing, and assembly preparation.
• Delivery alignment: inspection, packing, and shipment match your delivery plan.
For quality control, we inspect raw materials, check dimensions, and test finished products. We can provide a quality inspection report on request.
For repeat orders, keep the same drawing revision and sample approval on file. This helps both sides confirm that every batch matches the approved part, and it reduces disputes on quality or dimensions.
Get a Sheet Metal Fabrication Quote Within 24 Hours
We send a formal quotation within 24 hours after receiving your information. To get an accurate price, send:
• Drawings in CAD, PDF, or 3D format, or a physical sample
• Material and thickness
• Quantity, including trial and mass-production volumes
• Surface finish and special requirements
• Working environment or intended use
Incomplete requests slow down quoting. A clear drawing and quantity usually gets you the fastest and most reliable price.
Small-Batch Samples to Mass Production, Lead Times from 7 to 30 Days
We accept sample orders, small-batch trial orders, and mass production. Many buyers start with a sample to check fit and quality, then move to volume.
Lead time depends on complexity, process, and quantity. These are our typical ranges:
• Simple parts: 3 to 7 working days
• Standard custom products: 7 to 15 working days
• Large machinery or complex projects: 15 to 30 working days
We confirm the exact delivery time before you place the order. To protect your schedule, approve drawings and samples quickly and tell us about any planned changes early. Late design changes are the most common cause of delay in custom sheet metal projects.
Why Overseas Buyers Choose Zhongfu Metal as Their Sheet Metal Supplier
Overseas buyers usually worry about communication, quality, and delivery. We address each directly:
• Fewer suppliers: sheet, CNC, welding, and vessel work in one factory.
• Early feedback: we review drawings and samples before quoting.
• Process matching: we choose the cutting, forming, and welding route that suits each part.
• Export coordination: material, packaging, and logistics details stay aligned through the order.
We pack for export in wooden cases or cartons, and we support sea freight, air freight, and express delivery.
Direct Manufacturer, Not a Trading Company: A 7000-8000 sqm Workshop
Zhongfu Metal is a direct manufacturer. We operate our own workshop of 7000 to 8000 square meters for fabrication, machining, finishing, and vessel-related production.
Whichever supplier you choose, use this short checklist:
• Ask for workshop photos or a live video tour
• Request a quality certificate and a sample inspection report
• Order a sample before a large purchase
• Confirm payment terms and lead time in writing
• Check that the engineer reviewing your drawing can answer technical questions
