What a Real Carbon Steel Plate Inspection Looks Like

Recent photos from our carbon steel plate warehouse during customer inspection and loading. No renders — just real material, real handling, real shipment.

Plate Warehouse Ready for Inspection

Large quantities of carbon steel plates (Q235B, Q345B, A36, SS400) are stored in our warehouse with clear grade separation and visible mill markings on every piece.

Buyer Representative On-Site

The customer's inspector walks the warehouse to verify thickness, dimensions, surface quality and quantity. We provide full access, sampling support and certificate matching.

6 Things Every Buyer Can Verify

Our inspection process is built around the details that matter for carbon steel plate projects: grade accuracy, dimensional tolerance, surface quality and export-ready handling.

01

Mill Certificates & Heat Number

Match each plate bundle to its original mill test certificate (MTC), chemical composition (C, Si, Mn, P, S) and mechanical properties (tensile, yield, elongation).

02

Thickness & Dimensions

Measure thickness at multiple points, verify width, length, diagonal difference and flatness against ASTM A6, EN 10029, JIS G3193 or your project spec.

03

Surface & Edge Quality

Inspect for rust, mill scale, dents, scratches, laminations, pits and roll marks. Check edge condition for burrs, cracks and rolling marks that impair fit-up.

04

Flatness & Warpage

Lay plates on a flat surface and use straightedges. Verify deviation is within tolerance limits for your application.

05

Quantity & Bundle Count

Count sheets per bundle, weigh bundle, calculate theoretical weight and compare against packing list and contract quantity.

Third-Party Lab Test

SGS, BV, Intertek or customer-appointed inspection agencies are welcome at our mill and warehouse.
