Custom A36 Steel Plate Sourcing for Hydraulic Press Manufacturing
Macrodyne Presses & Automation needed a verified Chinese steel fabricator capable of producing custom-dimensioned, ASTM A36-compliant structural steel plates for their hydraulic press frames. Luckee conducted full on-site verification — from raw material coil provenance to live XRF chemical testing on the floor.
What Macrodyne Needed Confirmed
Macrodyne Presses & Automation manufactures heavy-duty hydraulic presses and automation systems for industrial clients across North America. Their press frames and platens require large-format, custom-dimensioned structural steel plates — often exceeding 150mm in thickness — with strict dimensional tolerances and verifiable ASTM A36 material compliance.
Finding a Chinese fabricator capable of delivering at this specification, with genuine mill-traceability and reliable custom cutting capability, requires more than a supplier profile. Macrodyne engaged Luckee to physically verify the supply chain from raw steel coil to finished custom-cut plate — confirming that the material, the fabrication process, and the documentation were all genuinely in place.
The audit covered three stages of the supply chain in a single visit: the raw material yard (Wuxi steel coil inventory), the CNC flame cutting workshop, and the finished custom plate warehouse — with live XRF chemical testing conducted on-site on representative samples from the production batch.
XRF Test Conducted On-Site — A36 Confirmed
The single most important verification for any structural steel supply relationship is chemical composition. Supplier-provided Mill Test Reports (MTRs) can be falsified, misattributed, or attached to the wrong heat. Luckee's auditor used a handheld XRF analyser directly on a representative plate from the production batch. The result: a confirmed carbon steel match with 99.74% Fe and 0.26% Mn — fully within ASTM A36 limits.
What the Audit Verified Across the Supply Chain
Six findings from the on-site visit — covering raw material origin, fabrication capability, dimensional compliance, and documentation quality.
Mill-Direct Steel Coil Supply — Wuxi Yard Inspected
ASTM A36 Composition Confirmed by XRF
BTHG CNC Flame Cutter — Multi-Torch, Active Production
Complex Custom Profiles and Pockets — Confirmed In-House
Plate Markings Cross-Checked Against Order Dimensions
MTR Provision — Confirmed Available, Format Improvement Recommended
The Supply Chain Through the Auditor's Lens

Supplier Approved for Macrodyne's A36 Steel Plate Programme
No critical findings were recorded. The factory demonstrated genuine CNC flame cutting capability for heavy-gauge structural plate, confirmed ASTM A36 chemical compliance via live XRF analysis, and showed a credible raw material traceability path from Wuxi mill coils through to finished custom plates. MTR documentation was available and traceable. One minor recommendation was made regarding English-language MTR formatting for Canadian import documentation. Macrodyne was advised to proceed to a trial order with mandatory third-party inspection of the first shipment.
