ZSJH
Customized steel stiffening plates are used to reinforce the web, flange, beam ends and column joints of the beams, providing additional load-bearing capacity in areas of local buckling or concentrated loads. The products can be delivered as cut and processed parts or welded sub-assemblies. ZSJH Steel supplies finished steel plate products rather than a standalone cutting-only operation.

We manufacture from customer drawings or approved shop drawings. Custom options include steel grade, thickness, outline, hole diameter and pitch, slots, notches, bevel angles, weld details, machined surfaces, flatness tolerance, coating system, piece marks and packing by assembly zone.
1. Review drawings, standards, tolerances and finished-part requirements.
2. Verify material certificates and maintain traceability.
3. CNC cut the plate outline and internal features.
4. Drill, slot, notch, bevel or machine as specified.
5. Assemble and weld ribs, tabs or subcomponents where required.
6. Straighten and inspect dimensions, flatness, holes and interfaces.
7. Perform specified visual and non-destructive weld inspection.
8. Blast, coat, mark, document and pack the finished plate product.
Is this page for cutting-only service?
No. Steel Plate Fabrication pages describe finished steel plate products that may include cutting, drilling, slotting, beveling, welding and surface treatment. Cutting-only work belongs to the separate CNC Steel Cutting Service category.
Can the parts be delivered with holes and weld preparation completed?
Yes. Hole groups, slots, notches and bevels can be completed before delivery according to approved drawings.
What information is needed for quotation?
Please provide drawings, material grade, plate thickness, quantities, processing details, inspection level, coating, packing and delivery location.
Send your steel plate drawings and finished-part requirements to ZSJH Steel for a fabrication review and quotation.
