OEM and ODM Steel Parts Made to Your Drawing
An equipment builder does not want plate, it wants the panel that bolts into the machine. Every step left to the buyer, from breaking down the coil to punching the bolt pattern.
An equipment builder does not want plate, it wants the panel that bolts into the machine. Every step left to the buyer, from breaking down the coil to punching the bolt pattern, is labor competing with assembly work that earns more. Tianyu Metal takes drawings and sample parts and supplies finished components in carbon, alloy, wear resistant, bullet resistant, stainless and coated material, using cutting, bending, welding, decoiling and punching with painted or galvanized surfaces where the product allows. ODM and OEM work is quoted the same way as stock material, with the grade and the certificate named before production starts.
The Problem
What This Removes From Your Procurement
Finished Parts Bought As Raw Material
Plate delivered to a machine shop still has to be cut, formed and drilled before it becomes a component. Buying the component instead moves that work off your floor and out of your labor cost.
Small Batches Nobody Wants to Quote
A recurring order of a few dozen panels sits below the interest of a dedicated fabricator. Processing it alongside the material supply keeps the batch worth producing.
Batch to Batch Drift on Repeat Parts
When the specification lives in a sales conversation it changes. Freezing grade, tolerance and hole pattern on the order confirmation gives every later batch the same reference.
Coating Added by a Third Party
Sending fabricated parts out for paint or galvanizing adds a handoff and a party who never saw the drawing. Where the product carries a painted or galvanized surface it is supplied that way from the start.
No Traceability on a Fabricated Assembly
An OEM audited by its own customer needs to show what the part is made of. The mill test certificate for the parent material is issued with the finished parts.
Step By Step
How We Run It
Drawing or Sample Review
A part described in words alone gets priced against an assumption. The first sample then differs from what the buyer had in mind and two weeks are gone. Send the drawing, or the old part you are replacing, with the material, the thickness and the quantity per batch. We confirm what can be produced as drawn and identify any feature that has to change before a price is given.
Material Selection for the Part Not the Catalog
Custom parts often inherit whatever grade the previous supplier used, which may be overspecified for most of the part and marginal at the one point that fails. The grade is chosen against the duty. Wear faces move to AR400 AR500 or AR600, loaded members to S460 S550 or S690, corrosive service to 304 316 or 2205, outdoor structures to galvanized or Zn-Al-Mg coated material, and tooling to P20 D2 or M2.
Quotation with the Processing Listed
A lump sum price hides which operations are included, so the buyer discovers at delivery that the holes or the paint were extra. The quotation lists the operations that are in the price, covering cutting, bending, welding, decoiling and punching, plus the surface as natural painted or galvanized, so nothing appears afterwards as a variation.
Order Confirmation and First Batch Agreement
Custom work repeated across several orders drifts. Batch three no longer matches batch one and the assembly line finds out with a part that will not seat. The confirmed order fixes grade, dimensions, tolerances, hole pattern, bend directions and finish, and that record is what every repeat batch is produced against rather than the memory of the last run.
Production and Fabrication
Parts made by separate suppliers for cutting, forming and coating accumulate errors, and no single party owns the finished dimension. Cutting, bending, punching and welding are carried out on the same order so the finished part is measured as a part, not as a sequence of separate services with a gap between each one.
Inspection and Certification
A fabricated component without material traceability cannot be used by an OEM whose own customer audits the supply chain. A mill test certificate is issued against the material grade and finished dimensions are checked against the drawing before packing. ISO9001 BV SGS and RoHS certifications are on file and copies are released on request.
Packing to the Assembly Sequence
A pallet of mixed components has to be unpacked and sorted before assembly can begin, which puts warehouse labor in front of production labor. Parts are marked by part number, counted into the packing list and bundled the way you assemble them, with photographs taken before loading so the batch can be checked against the order on arrival.
Deliverables
What You Receive
- Finished parts produced to your drawing with the hole pattern and bends as specified
- Material supplied in the grade agreed for the duty rather than a default catalog grade
- Mill test certificate for the parent material issued with each order
- Dimensional check of the finished parts against the drawing before packing
- Packing list by part number with quantities counted per bundle
- Photographs of the finished batch taken before loading
Who It Is For
Buyers Who Ask For This
- Equipment OEMs that want bolt in components rather than plate to break down
- Machinery importers replacing a local fabricator with a single supplier for material and parts
- Maintenance contractors ordering repeat liner and guard packages to a fixed drawing
- Can makers and packaging converters specifying tinplate to their own size and coating
- Structure builders ordering galvanized tube frames cut and punched to a standard design
- Brand owners specifying a private label product built to their own dimensions

OEM ODM and Custom Fabrication FAQ
What does your ODM and OEM service actually cover?
Material supplied in your specified grade and dimensions, processed by cutting, bending, welding, decoiling and punching, with a natural painted or galvanized surface where the product carries it. Work outside those operations is declined rather than subcontracted without telling you.
What do you need to quote a custom part?
A drawing or a sample of the part being replaced, the material grade or the duty it has to survive, the thickness, the quantity per batch and how often the batch repeats. Tell us which dimension is critical so the tolerance is applied where it matters.
Can you supply tinplate in our own size and coating?
Yes. Tinplate is supplied as coil strip and sheet in 0.15~0.50mm thickness and 600~1050mm width to GB/T 2520-2008 JIS G3303-2008 DIN EN 10203-1991 and ASTM A623M-2011, in coated and customized formats for can and packaging production.
Do you make welded assemblies or only single parts?
Welding is one of the processing services, so sub assemblies are produced where the design allows it. Send the assembly drawing and we will confirm which joints can be made here and which are better left to your own shop.
How do you keep repeat batches identical?
Grade, dimensions, tolerances, hole pattern, bend directions and finish are recorded on the order confirmation and every repeat batch is produced against that record, not against the previous run.
Is the custom part still supplied with a certificate?
Yes. A mill test certificate is issued against the grade of the parent material, so a fabricated component stays traceable for your own quality file and for your customer's audit.
